G. Maintenance schedule G 1. Service Correct maintenance at the right time is essential for reliable operation of the tractor. Maintenance costs are small compared with repair costs resulting from lack of maintenance. The most important measures are those which you carry out yourself which include lubrication and various checks and adjustments. The service intervals shown apply for normal operating conditions but in more severe conditions servicing should be carried out more frequently. Cleaning the tractor General cleaning instructions Protect environment following the following environment orders. The washing place must have a separator outlet when using some detergents. It is best to wash the new tractor for the first time during the first week of the start---up. Never rub back and forth. General instructions concerning oil checks and oil filling G 1.1. NOTE: Do not wax the paintwork of the new tractor before the initial washing. Do not let the tractor run during washing. --- Always stop the engine before starting work. --- Apply the parking brake to ensure the tractor cannot move. If the ground is uneven the wheels should be blocked. --- Wash down the tractor first so that the work can be done easily and quicker, see cleaning instructions (point G 1.2.). --- Always observe the utmost cleanliness in all maintenance work. Thoroughly wipe off filler caps and plugs as well as surrounding parts of the tractor before filling up with fuel or oil. Inspect the oil and filters when changing. Large amounts of dirt (e.g. heavily clogged filters) can point to a fault which could cause extensive and costly repairs if not corrected in time. --- When carrying out checks the tractor should stand on level ground. --- Levels should be checked in the morning when the oil is cold and has had time to run down to the bottom of the unit concerned. --- When changing the oil, bear in mind that the oil can be very hot when it drains from the tractor. --- Avoid touching the exhaust manifold, turbocharger and other hot parts of the engine. --- Keep the engine surfaces clean in order to avoid the risk of fire. --- The fuel, lubricating oil and coolant cause irritation to skin if in contact for long periods. --- After completion of service work replace all safety covers etc. --- Waste oil, liquid waste, oil filters and batteries should be handled carefully and disposed of properly. Greasing lubricating points fitted with grease nipples --- Always clean the grease nipples before applying the grease gun. --- Apply grease through the nipples until clean grease oozes out (unless otherwise instructed). --- Wipe away superfluous grease which has been pressed out at the lubricating point. --- Preferably carry out lubrication with bearing points and joints unloaded and with the bearings in different positions. G. Maintenance schedule G 1.2. When washing do not use special nozzles (t.g. turbo nozzle). Keep the nozzle of the pressure washer at least 30 cm from the sealing points and paint work. The temperature of the washing water may not be higher than 50˚C. Follow also the instructions of the manufacturer! When washing the cabin sides do not let the water get to the cabin air filter (in the side plate, usually on the left). Do not wash the inside of the cab with a pressure washer or running water. Do not point the pressure washer towards to the electrical equipment, electrical connectors, lead---through points, bearings, seals and locks. Use lower pressure, 65 bar / 940 psi) and point the water jet diagonally to the above points. Do not point the pressure washer towards the radar sensor (distance min. 1m and the max pressure 65 bar / 940 psi). When using the so---called cold fat remover, do not keep the tractor in sunshine, the paintwork must not be hot otherwise the paintwork may be damaged. After washing grease the lubricating points, the joints and bearings must be lubricated with oil. Wax the painted surfaces. Engine compartment Keep the engine surfaces clean in order to avoid the risk of fire. Do not wash the hot engine, fire risk. Radiator honeycombs Clean all the radiator honeycombs regularly using compressed air or by flushing with water (according the maintenance program). Bellows of front axle suspension (air---suspend front axle) To ensure correct function of the front axle suspension, the dirt in the bellows of the suspension and in the housing have to be occasionally removed (detach the housing, if necessary). ---94--- Keep the pressure washer nozzle during washing at distance of at least 30 cm from the bellows. The temperature of the washing water may not be higher than 50˚ C. Do not use special nozzles when washing (Turbo nozzle). Cleaning the polycarbonate windows If the cab has the polycarbonate windows clean them according to the following instructions for keeping the windows bright as long as possible: --- Clean the stains by wiping using a detergent or plenty of water. Never rub back and forth. --- Never use the window wiper on a dry window. --- Ensure that there is enough fluid in the washer reservoir. --- Never clean the window using a sharp tool like an ice scraper. --- Never use an abrasive detergent. --- Do not point the pressure washer towards the side seals or lead---through seals because the possible detergent may reach the uncoated glass parts. However the coated window withstands well different detergents. G 1.3. Lubrication and maintenance schedule NOTE: All intervals are counted from zero hours on the hour recorder. For example, the 500 hours service is carried out after 500, 1000 hours etc. even if the measures have been carried out at the 100 hours service. Example: The 1000 hour service contains all items mentioned under the 10 hr/daily and the 50 hr/weekly checks as well as the 500 hr service. G 1.4. Service inspection (after 100 hours) Your dealer gives a cost---free service inspection (excluding oil and filter costs) to all new tractors after 100 hours running. The service procedure is as follows: 20 Engine --- Change engine oil and filter --- Change prefilter, fuel system --- Change fuel filter 40 Power transmission --- Change pressure filters and hydraulic return filter 60 Front axle and steering system --- Change oil in differential --- Change oil in hubs Other points --- Lubricate according to chart --- Road test tractor. Check during the road test all the functions of the controls and instruments. After the road test, check for oil leaks, check the coolant and fuel system. ---95--- G. Maintenance schedule G 2.

G 2.2.3. IMPORTANT: To mix fuel with any admixing materials is not allowed. G 2.2.1. Fuel --- The properties of light fuel oil that is only intended for warming use do not meet the requirements of modern diesel engines and cannot be used as fuel. --- In particular, distributor---type injector pumps require the fuel to have sufficient lubricity, because they do not have oil lubrication in the same way as typical multi---element pumps. Adding oil to diesel fuel is not recommended, because it causes carbon build---up, and if oil is mixed with even a small amount of water it will clog the filter. --- Additionally, various fuel quality requirements imposed by taxation and seasonal changes have to be taken into consideration. G 2.2.2. EN ISO 3104 Fuel storage --- Storing and distributing fuel must be arranged in conditions where no water or impurities can enter the storage tanks. The storage tanks must be installed in a slanted position, so that water and impurities are collected at the opposite end from the suction pipe of the pump. The suction pipe of the pump should not reach the bottom of the tank. --- Water must be periodically drained from the tank in order to prevent problems. Refueling at the same time the tank is being refilled must be avoided without exception. --- When the tank is filled with winter---quality fuel in good time, the engine is guaranteed to run flawlessly during the cold season. Filter system --- The engine’s standard filter system gives sufficient protection for the injection system from impurities that can be present in well---tended distribution systems. --- The control of distributor---type injection pumps is based on internal pressure, which will drop if the fuel system is clogged. If the pilot pressure drops too low, engine power is reduced, smoke increased and starting becomes more difficult. Additionally, water in the injection system will destroy it in a very short time. For this reason, the water trap and the filters must always be serviced according to the specified amount of running hours. --- It is also important always to use original Valtra (or Sisu Diesel) fuel filters. They guarantee sufficient filtration, preventing impurities from damaging the fuel system. There are many cheap filter kits (so---called pirates) on the market, with lower quality and performance in order to minimise the cost. Among other things, the quality and amount of filter paper are often insufficient. There are also often dangerous defects in the basic structure that may cause expensive damage even in a short period of time. G 2.2.4. Biodiesel fuel The only possible alternative fuel to use is RME (Rapeseed Methyl Ester) Biodiesel according to European norm EN 14214 or US norm ASTM D6751. When using Biodiesel the engine capacity is almost the same as using diesel fuel. In Tier 3 SisuDiesel engines with Common Rail fuel injection system only max 20% dilution of Biodiesel (B20) is allowed. ---97--- G. Maintenance schedule G 3. Grease Valtra Grease Moly, NLGI2 Moly Grease Always use the following greases in Valtra tractors. Each point requires it own type of grease. Valtra Grease, NLGI2 Universal grease Lithium ---based universal grease. Is suitable for greasing all heavy machines. ---25˚ ... +130˚C Universal grease of high quality, lithium based grease for vehicle use. It is recommended for greasing wheel bearings, chassis water pumps, catepillar rollers etc. The grease is adhesive, protects against corrosion and resists water and varying temperatures. Temperature range is ---25˚ ... +130˚C. Valtra Calsium LF, NLGI2 Calsium Grease LF Is suitable for greasing all heavy machines. Lithium ---based universal grease. Molybdenum sulphide as an additive (1---3%) improves greasing in places exposed to shock loads. ---25˚ ... +130˚C Universal grease of high quality, lithium based grease for vehicle use. It is recommended for greasing wheel bearings, chassis water pumps, catepillar rollers etc. The grease is adhesive, protects against corrosion and resists water and varying temperatures. Temperature range is ---25˚ ... +130˚C. Avoid repeating skin contact. Protect nature and take care of empty packages. Is suitable for greasing all heavy machines. Long fibre grease. Colour red. Especially good for greasing points exposed to water. ---25˚ ... +80˚C Calsium LF is of long fibre, high quality and calsium based universal grease for vehicle use. It is recommended for greasing chassis, water pumps, pins etc.The grease is adhesive, protects against corrosion and resists water and varying temperatures. Temperature range is ---25˚ ... +80˚C. G 4. Maintenance schedule PERIODICAL MAINTENANCE---schedule (according to operator’s manual) is recommended for all tractors and specially for tractors, which have more than 1000 running hours in one year. The periodical maintenances from 50 hours onwards can also be ordered from the authorized workshop. In that case the periodical maintenance is carried out by Valtra authorized and trained service personnel. Observe when doing the services that if the tractor is equipped with extra equipment like towing device, air condition, air pressure brakes etc. the periodical maintenances and checks for them must be carried out. The extra equipment which needs servicing is given in the end of this manual in section ”K”. YEARLY MAINTENANCE---schedule should be carried out by an authorized workshop, but for tractors which have under 1000 running hours in one year the operator has to carry out the normal service routines according to the following table (like daily and weekly periodic maintenance).

H 1.1. 1 Air filters A H49 A low---pressure indicator with a warning lamp is connected to the air cleaner. When the lamp (A) lights up on the instrument panel, the filter must be cleaned. If the indicator light illuminates quickly in dusty conditions, check the ejector pipe (1) is fitted properly. 2 A H48 Cleaning 1 Always stop the engine before cleaning. A blockage of the air filter is indicated by a change of the engine beat, smoky exhaust and reduction of engine power. --- Check the inside of the air cleaner housing and the inlet pipe. Dirt on these parts indicates that the filter element is defective or has not been fitted properly. Change air filter (1): --- At least once a year --- After every 1000 hours --- After 5 cleanings, when the indicator light for the air cleaner has illuminated 5 times Change safety air filter (2): --- At least once a year --- After every 1000 hours Unless it is necessary do not open the cover of the air cleaner housing. Only associated with the situations mentioned before. During the maintenance check, that the cover of the housing, pipes and unions are in good condition. A H50 --- To clean the main element carefully blow out the main element from the clean air side (side with sealing) with compressed air (maximum 5 bar) until no more dust escapes. By doing so, the tip of the compressed air gun must not touch the main element. IMPORTANT: The filter element must not be cleaned more than 5 times, after which it must be replaced. The filter must be changed every 1000 hours in accordance with the maintenance requirement: --- Before refitting, check the paper bellows and the rubber seals on the cleaned main element carefully for damage. ---101--- H. Periodic maintenance --- Damaged main element must be changed. Filters uncoupling and coupling, see maintenance point 24 on page 112. Maintaining the cyclone block The cyclone block should be checked regularly and cleaned if necessary. 1 2 --- Unscrew the central bolt and remove the cyclone (3). IMPORTANT: Do not damage the cyclone cells, do not use hard or sharp tools. --- Remove foreign bodies and dust deposits from the cyclone block and in the housing by e.g. using a brush. --- Loosen stubborn dust deposits on the cyclone block by soaking in compatible cleaning agent and removing with a water jet. --- Blow---dry the cyclone block to prevent more dust from adhering. --- Insert the cyclone block into the housing and tighten the screw (6 Nm). 3 A H52 --- Loosen the bolts (1) of the air intake box and remove the air intake box (2).

Adding oil should be done through the oil filler cap (2). Stop the engine and allow it to stand for a few minutes before checking the level so that all the oil has had time to run down into the sump. For the correct oil grade, see Recommended fuel and lubricants on page 96. A H54 The expansion tank (1) has a liquid level sign (2) where the liquid level must be when it is cold. Hot liquid level is higher. IMPORTANT: The coolant pump is provided with a drainage hole on its underside. This hole must not be blocked. If coolant drips out of the hole, the pump seal is faulty and should be changed immediately. There may be slight leakage on a new engine before the pump has been run in. H. Periodic maintenance ---102--- Freezing point of coolant H 2.3. Check the freezing point of the coolant at the beginning of the cold season. If the freezing point is too high, drain off some of the coolant and top up with anti---freeze. Run the engine for a while until the anti---freeze has been mixed in, then re---check the freezing point of the coolant. Drain the cooling system completely every second year and refill with new coolant. IMPORTANT: Never use just water as a coolant. Check for leakage (oil, fuel, coolant) (3) Check, that there are no leakages. Check also radiator grilles and clean if needed B B 3 B 4 1 2 N H62 When cleaning use air pressure, a water hose (not pressure washer) or a soft brush (be careful not to damage the cores). Direct the spray against the air streaming direction. The tractor is equipped with the following coolers/radiators: --- Gearbox/hydraulics oil cooler (1) --- Air conditioning cooler (2), extra equipment --- Engine intake air cooler (3) --- Engine coolant radiator (4) By opening the locking latches (B) the first coolers pivot forwards to make cleaning easier.

Check prefilter and fuel filter (9) --- Open the locking (1) and turn the battery casing and the steps to open position down. --- If necessary slacken the screw (2) before moving the battery from its place. --- The battery electrolyte level should be on the level marked on the battery. If the battery has not that mark check that the electrolyte level is approx. 5---10 mm (0.2---0.4 in) above the cell plates in the battery. --- Top up with distilled water if required. --- Under no circumstances should you attempt to replenish the battery acid yourself. --- Never use a naked flame to check the level of the electrolyte. NOTE: If the water in the battery evaporates too quickly, it may be a sign that the charging voltage is too high. Keep the battery clean and dry on the outside. Protect the pole studs and the cable terminals with grease. 2 1 3 WARNING: Be careful with the battery solution --- it is corrosive! N H64 Drain the fuel prefilter into a container, NOT ON THE GROUND, by opening the tap a little (1) at the bottom of the prefilter. By opening the airscrew (2) in the upper part of the prefilter water comes out easier. After draining water close the tap and the airscrew. Drain the prefilter more often to reguired. IMPORTANT: During the cold season it is important that the engine is allowed to run for a while after topping up with distilled water, otherwise the water may freeze before it has had time to mix with the battery acid. Also check cables and battery terminals and clean them if necessary. Drain water from the fuel filter by opening the tap (3) in the bottom of the filter. Close the tap. Drain the fuel filter more often if reguired. IMPORTANT: If there is water in the fluid; it can damage the pump and the nozzles. If necessary bleed the fuel system, see instructions on H. Periodic maintenance ---106--- H 3.8. DANGER: When welding the discs the tyre must be away from the rim/ disc, DANGER OF EXPLOSION! Check tyre pressures (11) NOTE: Check the tyre pressures regularly (values are listed in Technical Specifications on page 127). When mounting the tyre on the disc the pressure limit is 250 kPa. If the tyre does not go on the disc properly, remove it and refit. When the tyre is positioned correctly on the disc, inflate to correct pressure. DANGER: Avoid over inflation as excess pressure may cause the tyre to explode. It is recommended that the changing of tyres and wheels is carried out in a professional tyre workshop which is equiped to handle this type of work. H 4. H 4.1.

Check the condition of the filter. A damaged filter must be changed. Check brake fluid level (14) WARNING: The air filter element does not remove chemicals from the outside air. The instructions of the pesticide manufacturer must be abided with when using extra activated charcoal filter. Brake fluid As extra equipment is a larger air filter housing with active coal filter or larger air filter available. Also check the windscreen washer fluid (if the tractor also has a rearscreen washer, it has its own reservoir at the rear of the tractor). During the cold season you must use an anti---freeze agent in the fluid. H 4.5. Check wheel nuts tightness (16) CAUTION: Regularly check the tightness of the wheel nuts also the wheel disc/rim bolts (values are listed in Technical Specifications on page 127). N H61 WARNING: Brake fluid is corrosive and poisonous and must be handled carefully at all times (it also corrodes the paint). H 4.6. The fluid level should be between the max. and min. marks. Top up with new fluid as necessary, see recommended fuel and lubricants on page 96. Check brake pedal free travel (17) WARNING: Normally there will be no need to top up the fluid. If leakage has occurred, it must be repaired immediately, before driving. If necessary, contact the authorized Valtra---workshop. The brake fluid level should be checked frequently. Use recommended fluid only. H 4.4. Clean cab ventilation air filter (15) 6080---86 The free travel should be 70---80 mm (2.8---3.1 in) with the pedals latched together. Adjust the free travel if necessary (see Checks and Adjustments on page 121). Parking brake adjusting instructions can be found under Checks and Adjustments on page 121. N H17 Do the cleaning more often if needed. Detach the filter housing cover from the upper LH corner of the cabin roof and remove the filter. Knock the filter element against the palm of your hand, clean it with the vacuum cleaner from the outside in or blow it clean with compressed air from the center outwards. Make sure that H. Periodic maintenance ---108--- Change pressure filters (power transmission and hydraulic system) and return oil filter of auxiliary hydraulic (18) H 4.7. H 4.8.

A Hubs N H18 NOTE: Change pressure filters (A and B) and return oil filter (C). The filters are similar. If the lamp indicating a blocked filter (D) is illuminated (common indicator light for all three filters) when the oil has been warmed, then change all three filters. If the indicator lamp illuminates when using auxiliary hydraulics it is probable that the auxiliary hydraulic return filter is blocked. This can be checked by disconnecting the pressure sensor wires and running the engine. If the indicator lamp does not light now, the fault is in the return filter. Then only the return filter need be changed. --- Fit a suitable container under the filter and clean the filter housing and the surrounding area. Remove the filter housing and filter element. --- Wash the filter housing in diesel fuel and fit a new element (lubricate new seal). Do not use the old seal. --- Refit the filter housing and tighten with a suitable wrench to a torque of about 200 Nm. IMPORTANT: Always change the pressure filters (A and B) if repairs have been carried out due to impurities in the hydraulic system. If one or the other of the pressure filters illuminates, indicator lamp (D), both filters have to be changed. N H42 Turn the wheel until the oil surface indicator line is horizontal. The oil surface should be level with the hole. Add more oil if necessary (recommended oil and lubricants on page 96). ---109--- H. Periodic maintenance H 5. Maintenance every 1000 hours or yearly 3. Clean the insert in diesel fuel and dry it with compressed air. Change the insert if damaged. 4. Refit the suction strainer (2) and the cover (1). IMPORTANT: In conditions where the hydraulic system becomes dirty quickly, the suction strainer has to be cleaned more frequently. If the operating sound of the pump changes to a shrieking noise, the engine must be stopped, the suction strainer cleaned and the oil checked to ensure that its viscosity corresponds to the manufacturer’s recommendation. Change oil in power transmission/hydraulic system and clean the suction strainer (20) H 5.1. H 5.1.1. Draining H 5.1.3. Filling 1 1 2 2 2 3 6080---91 Run the tractor until the gearbox and hydraulic lift are warm as this will speed up the oil drainage and most of the impurities will come out with the oil. Lower the hydraulic lift. N H57 Remove the drain plugs under the gearbox (1) and brake housings (2) and drain the oil into a suitable container. Clean and refit the plugs. H 5.1.2. For the correct oil grade see ”Recommended fuel and lubricants” on page 96. When changing oil it is recommended to refill by pump through the hydraulic return coupling (3), then the oil goes through the return filter. When filling the oil through the filler cap (1), care must be taken with cleanliness. Cleaning suction strainer The oil level should reach the min mark on the dipstick (2); this is equivalent to 55 liters of oil with 30 liters for the auxiliary hydraulics.Normalfilling is between min and max mark. If more oil is needed for the auxiliary hydraulics, fill up to the max. mark on the dipstick. This is equivalent to 65 liters of oil; with 40 liters for the auxiliary hydraulics. As well the brake cooling improves with the larger amount of oil. After filling the system, start the engine and check the oil level. 1 IMPORTANT: When attaching implements to the auxiliary hydraulics. Note if there is dirty oil in the implement it will contaminate the clean oil in the tractor. Implements also require oil changes from time to time. 2 1 IMPORTANT: After driving for a short while check through the filler hole that the oil does not foam. Foaming is a symptom of a leaking cover gasket. If the oil foams, tighten down the cover or change the seal. N H20 1. Remove the cover (1) and the suction strainer (2). 2.

Maintenance every 2000 hours or every other year Change radiator coolant (32) If problems occur with the function of the cooling system this could be a sign that the whole system needs to be thoroughly cleaned as follows: Clean the cooling system using a special cleaning agent available from your dealer. Follow the manufacturer’s instructions. H 6.1.1. 3 Draining coolant N H69 1 --- Connect a hose from the draining cock of the cylinder block to a clean container and open the plug (3). --- Turn the heater control in the cab clockwise. --- Drain the water pump by cranking the engine a few revs with the drain plugs removed. Before filling, close: --- Fasten the radiator lower hose (2) --- The drain cock (3) of the cylinder group A H63 Always stop the engine before draining coolant. --- Open the cap (1) of the expansion tank. Open the expansion tank cap carefully. At running temperature the expansion tank has overpressure (1,0 bar). 4 N H70 --- Loosen the hose placed on the thermostat housing going to the expansion tank and check that the restrictor hole (Ø about 2 mm) in the union (4) is open. Refasten the hose. H 6.1.2. Filling Ensure that a recommended coolant is always used. 2 A H35 --- Loosen the lower water pipe (2) (remove the finger shield if necessary). The best way to drain the system is to loosen the upper end of the pipe and then loosen the lower end, then the pipe can be bent to the side and the fluid drained into a container. All models 12 liters Mix the antifreeze and water according to the manufacturer’s instructions. IMPORTANT: Never fill up with cold fluid while the engine is warm. Do not use plain water as a coolant. ---115--- H. Periodic maintenance H 6.3. Check function of fuel system injectors (34) 5 A H65 --- Fill the system to the expansion tank fluid level mark (5). After filling the fluid run the engine for a time and check the level of fluid. H 6.2. Change brake fluid (33) A6181---107 If the engine is to continue to give full power output, the injectors must be maintained in first class condition. Checking and cleaning should be carried out by an authorized workshop. Symptoms of dirty or faulty injectors are: N H61 --- Knocking is an indication that one of the injectors is faulty. When a cold engine ticks over a certain amount of knocking is unavoidable. If the engine knocks after it has reached normal operating temperature, it is very likely that one of the injectors is faulty. Air in the fuel system can also cause knocking (which should disappear after the system has been bled of air). --- Smoky exhaust gases may indicate impaired performance of the injectors. However, this can also be caused by other faults such as a blocked air cleaner. WARNING: Brake fluid is corrosive and poisonous and must be handled carefully at all times. It is recommended that the brake fluid be changed every second year or after 2000 hours of operation. --- Empty the brake fluid reservoir, open the bleed nipples. It is better to place hoses from the nipples into a container, as the fluid corrodes the paint. Pump the brake pedal until all brake fluid in the pipes and cylinders has run out. --- Fill the brake system with new brake fluid. --- Bleed the brake system of air (see Checks and Adjustments on page 121). If the tractor is equipped with the trailer brake valve and/or air pressure brakes as extra equipment, open also their bleed nipples to drain the hoses. The brakes must also be bleeded from the nipples in question: --- the fluid brakes of the trailer, see the bleeding instructions on page 149. --- the air pressure brakes, see the bleeding instructions on page 149. The correct amount of brake fluid is 0.5 liter. H. Periodic maintenance ---116--- I. Checks and adjustments Check and adjustment instructions for the extra and alternative equipment are in section K, after each extra equipment. I 1. I 1.1. Engine Bleeding fuel system I 1.2. Air filter There should be no air in the fuel system to ensure that the motor function is of maximum efficiency. The system automaticly removes the small guantity of air which has built up in the filters and injection pump. The fuel system must be bled if any part of it has been removed or if the tractor has run out of fuel during driving so that air has entered the system. Bleed the fuel system as follows: 2 A I15 1 The air cleaner prevents dust and other particles from entering the engine with the induction air. Engine wear is largely dependent on the cleanliness of the induction air, so it is very important to check the air cleaner regularly and to maintain it correctly. 1 N I33 1. Pump by hand the lever (1) on the fuel pump. If pumping feels ineffective, turn the engine a little, so the camshaft turns away from the line of the pump arm. IMPORTANT: The safety filter (2) behind the main filter (1) must not be cleaned but must always be changed according to the maintenance schedule. The purpose of the safety filter is to prevent damage to the engine if the main filter should fail. Cleaning the main filter, see maintenance on page 101. 2 A I14 2. Start the engine to the low idling, do not race. If the engine does not start, open the union (2) of the bleeding pipe from the fuel filter to the injectors. Pump by hand pump, until the fuel is running out from the union. Tighten the union and dry the fuel overflowed. IMPORTANT: Do not open the union in the upper part of the prefilter, because it is on the suction side. 3. Start the engine and check that there are no leaks. ---117--- I. Checks and adjustments I 1.3. Maintenance---cooling system the cooling system functions correctly: --- Check the coolant level (see maintenance point 2 on page 102). --- Check the fan belt (belts) tensions (see maintenance point 8 on page 105). --- Clean the radiator honeycomb externally using compressed air or by flushing with water. I 1.3.1. M I3 The following action should be taken to make sure that I 2. I 2.1. The cooling system is filled with a mixture of water and anti---freeze agent on delivery. The anti---freeze agent also prevents rust from forming in the cooling system. However, the anti---rust properties of the agent diminish with time, so it is important to change the coolant at regular intervals. A suitable mixture is one part anti---freeze agent to one part water, but the manufacturer’s directions should always be followed (see maintenance point 32 on page 115, maintenance after every 2000 hours). Electrical system Battery checks and maintenance I 2.2. Alternator The tractor has a negative---grounded alternator which can easily be damaged if incorrect connections are made in the electrical system. For example, connection of the battery with wrong polarity can burn out the alternator or rectifier. The electrical charging circuit must not be broken when the engine is running. I 2.3. A6181---114 --- Check the charge in the battery using a hydrometer (”acid tester”). The density of the electrolyte should be at least 1,23. --- Make sure that the fan belt (belts) are always correctly tensioned. --- Keep the battery clean. It can be washed with lukewarm water after removal from the tractor (always disconnect the negative lead first). --- Also clean the pole studs, the cable terminals and the battery retainer thoroughly. Wash off oxidized spots with water. Wipe the outside of the battery when it is clean, and coat the pole studs and the cable terminals with petroleum jelly. --- Refit the battery (always connect the positive lead first). DANGER: Avoid sparking or naked flames near the battery. The battery gives off explosive hydrogen gas! Battery electrolyte is corrosive. I. Checks and adjustments Coolant Safety precautions for the electrical system --- Always connect the battery with the correct polarity. --- Disconnect the negative lead of the battery first and connect it last. ---Never open the charging circuit while the engine is running. --- Disconnect the negative battery lead before removing the alternator. --- Remove the battery caps during charging to prevent the build up of explosive gases in the battery. Do not connect any additional electrical equipment, as this may damage components of the existing electrical system. I 2.3.1. Welding IMPORTANT: The battery leads (negative first) and the alternator wiring have to be disconnected before arc welding is carried out on the tractor or an implement which is attached to it. IMPORTANT: Never run the engine with the alternator disconnected. ---118--- I 2.4. Fuses N I32 The fuse box, which is positioned under the instrument panel should always be kept clean. It contains 30 fuses. The nominal current rating of the fuses is between 5---30 A. If any of the fuses blow, the fault must be traced and remedied. Fuses must not be replaced with ones of a higher rating, as this may cause damage to the electrical equipment. The fuse diagram is placed under the fuse box (it is shown in the figure above). There is space for reserve fuses between the fuses. When you need a continuous electrical supply e.g. to the implement, illumination etc. power can be taken from the trailer connection (see page 82). With the implement control system (optional equipment) electrical power to the optional equipment can be switched on and off from the driver’s cab. Power for optional equipment can also be taken from the spare fuses or unused optional equipment fuses. A continuous current source can be connected from the main current pole of the starter motor (on the models with main circuit breaker, current is switched off with main switch) through the new fuse.

Headlight adjustment Correct adjustment of the headlights is very important when running on the public road. Headlight adjustment can be carried out quickly and accurately by using an optical headlight adjusting unit. If no optical instrument is available, adjustment can be done as follows: If tractor has up lifted full/dipped beam headlights (on the top part of the cab), the lights have to be adjusted so that the light pattern shines on the mark at a distance of 30 m on even ground. Lights which can be mounted under the lower part of the front frame can not be used on general roads. Check before adjusting the headlight that the tractor loading is normal and tyre pressures are correct. With dipped---beam switched on, the cutoff edge of the light pattern should come at height H when the tractor is at distance L. With full---beam switched on, the distance between the light points should be B. Any necessary adjustment is done using the headlamp adjusting screws. A6181---118 Measurements: L=5m B = Distance between headlight centers H = Height of headlights above ground minus 50 mm (2 in) I. Checks and adjustments ---120--- I 3. I 3.1. Brake system Adjusting travel of brake pedals 1---2 mm 2A A 2 1 1 3 3 N I29 The pedal free travel should be 70---80 mm with the pedals latched together. It can be checked as follows: --- Fit blocks in front of the front wheels to prevent the tractor from moving --- The tractor engine must be running, shuttle --- speed gear --- and range levers have to be in neutral position --- Raise the rear wheels off the ground so that they can be turned by hand. --- Tighten the adjusting nut (1) until the wheels cannot be turned by hand any further. --- Slacken the adjusting screw 1.5---2 turns and check that the wheel can rotate freely. --- Check that the brake action is the same on both wheels while driving with the pedals latched together. Check the pedal free travel. I 3.2. Adjusting parking brake The parking brake is controlled with a spring return pressure cylinder and it is connected to the foot brake mechanism by a cable. The parking brake is adjusted in the factory and re---adjustment is not necessary unless parts of brake mechanism have been changed (the parking brake is affected when the foot brakes are adjusted). IMPORTANT: Always adjust the driving brakes before adjusting the parking brake. When adjusting, the parking brake has to be off. The tractor engine must be running, shuttle --- speed gear --and range levers have to be in neutral position, fit blocks in front of the front wheels to prevent the tractor from moving. Pull the cable clearance to the end of the cable (to direction of arrow A). Open the locking nut (2) and adjust through the adjusting nut (2A) the tolerance is 1---2 mm. Tighten the locking nut. IMPORTANT: When mounting the parking brake cable, the cylinder side end has to be mounted according to the tolerances, this should only be carried out by an authorized workshop. I 3.3. Bleeding brake system of air NOTE: Check that the brake fluid reservoir is full before starting to bleed the system. Bleed the brake system in the following way (the brake pedals should not be latched together): --- Depress one of the brake pedals and at the same time open the bleed nipple (3) on the brake which is being actuated by the pedal. Before depressing the brake pedal and opening the bleeding nipple, pump several times on the pedal in order to build up pressure in the system. --- Depress the brake pedal fully and close the nipple and slowly let the brake pedal up again. --- Repeat the pumping action with the brake pedal until the brake fluid which runs out at the bleeding nipple is completely free of air. --- The procedure for bleeding the brake is the same on both sides. --- Check the brake fluid amount in the reservoir after bleeding and top it if required. If the tractor is equipped with the trailer brake valve or air pressure brakes as extra equipment, they all must also be ---121--- I.
