For more information: http://www.monarkexercise.se 4 LC6/LC7 Congratulations on your new test bike! Ideal position is important for performance to reach its maximum. LC6/LC7 has a brand new frame that is adjustable in all directions. The frame also allowes the Q-factor to be reduced, which further increases the possibilities for a perfect performance. The new setting options, along with an upgraded braking system, make Monark's renowned bike even better. LC6/LC7 gives the conditions; the rest is up to the rider. In today's society we are used to customizing our machines and tools for our own needs. The same applies to LC6/LC7. Through intelligent solutions parts can be customized according to user requirements. LC6/LC7 is also prepared for additional equipment, channels behind the covers make it easy to install different equipment for different needs. LC6/LC7 is a great bike as it is, with additional equipment, it can be even better. Force is a strong word which brings many associations. For us, force is interesting when it can be measured and calibrated. A brake-force must to be right, regardless of the system, be calibrated and controlled. On LC6/LC7 the brake system and calibration have been updated so that it is safer and more accurate. It is also quicker to adjust and has more options in that it is speed-independent, but can be switched into constant braking force as an alternative. Monark has always been known for the bikes measurement accuracy, now it's even better.

Initial operation LC6/LC7 is mechanically calibrated in the factory. The user may wish to verify this by performing the mechanical calibration of the pendulum weight. See ”Electronic calibration”. 1 2 Apply power to the test bike by first connecting the cable from the power adaptor to the test bike at the power connector(3) at the right side of the bike, see Fig: Front cover right. Then plug the power adaptor into the wall outlet. Turn on the power switch (2) and a green LED (1) lights up. The cable from the power adaptor can be locked with the clamp (4) which is placed below the power connection. Perform the electrical calibration as specified in section "Calibration Electronics”. Test pedal the bike. If the bike is working properly, it is ready for use 3 4 Fig: Front cover right 1) LED (voltage indicator) 2) Power switch 3) Power input 4) Locking for cable (power adaptor) 8 LC6/LC7 Operating Instruction Here are instructions for connection and options for connection to external devices. If advanced technical documentation / data protocol for system builders or similar are required, contact Monark Exercise AB. The control is performed over a serial line using ANSI/ ISO/ASCII format commands. Connector, a 9-pin D-Sub (male) located below the RPM meter, see Fig: Connector, is compatible with the RS232 standard. Power on crank or flywheel The bike need not be switched off when connecting external components, but it is recommended to prevent transmission of incorrect data between devices over the connection. Monark bikes measures the effect of the flywheel, so it will be a friction of 6-8% if you measure the impact of the pedals (measures the effect of the crankshaft, the difference is 4-5%). These percentages will be primarily due to friction in the chain, pedals and bearings. Be careful when connecting different types of external equipment to prevent flash-over and subsequent injury. The user must ensure that the correct cables are used, otherwise you risk serious injury or equipment damage. LC6/LC7 is designed for fitness tests and is set for power measurements on the flywheel. The bike can be set to work with effect in the pedals / crankshaft (the cycle constant). Control of the bike LC6/LC7 is built on a solid framework, a large wellbalanced flywheel, a brake belt and a pendulum that measures the braking force. The pedals operate around the brake wheel via a chain, while a stretch mechanism tightens the brake belt to regulate the braking force to affect the flywheel. This brake force is given directly by the pendulum against the scale on the right side of the bike. The computer system consists of a main unit (built in the bike) and a control unit (integrated computer on the bike, PC, terminal or other external equipment). The main unit reads pedal speed and braking force and to determine the test subject's heart rate by a chest belt, where applicable. In addition, the main unit activates an actuator, which adjusts the brake belt tension that regulates the braking force. This brake force is varied automatically in relation to changes in pedal speed, so that a constant power is maintained The bike is as default rpm-independent. For information about how respective control units works, see respective sections. The bike can be controlled externally by PC, terminal or other external equipment. 1 Fig: Connection 1) RS232 connection Measured quantities The following units are normally used. Where multiple units are specified, the user can select, see the software documentation.

When power is turned on to the bike it will beep, and from the number of beeps the command type can be determined. • Command type 0: A long beep. • Command type 1: A long beep followed by a short beep. • Command type 2: A long beep followed by two short beeps. • Command type 3: A long beep followed by three short beeps. Connection to PC To connect a PC to the bike, use a 0-modem cable (RS232) with 9-pin D-sub connector (female) at both ends. If no serial port is available on the computer, use a USB-serial adaptor (included) for connection to the USB port. 1 In order to control the bike use the PC software (Monark 939 E Analysis Software) supplied with the bike, which is common for models 831 E, 839 E, 939 E and LC6/LC7. Other external PC software that are compatible with the bike can also be used. Fig: Connection 1) RS232 connection Terminal Mode PC A variety of settings can be made from the software. For more information about this see the software's help file. Settings can also be made directly from the PC through the terminal mode, see the Technichal Manual which is available from Monark Exercise AB. 12 LC6/LC7 Management of connections Display with integrated computer on the bike (LC7) Make sure the power adaptor is connected to the bike Make sure the USB cable is plugged into the bike computer and the computer has power (needed if the computer's internal battery is drained). The computer can be powered from the bike power adaptor. Set the bike power switch to "on" and then start the computer. Now you can start the computer software in the computer. If you get a message that the connection can not be obtained probably the wrong COM port is registered in the software, see the manual to the software. Connecting external equipment directly to the RS232 connector (LC6/LC7) Make sure the power adaptor is connected to the bike Set the bike power switch to "off" then remove the USB cable from the bike computer. NOTE! It is important that the USB cable is disconnected from the bike computer, otherwise there may be a conflict between the external computer and the display with integrated computer. Insert the supplied RS232 cable to the RS232 connector below the RPM meter. Connect the other end of the RS232 cable to the external equipment. Set the bike power switch to "on" and then start the external equipment. Connecting an external computer (LC7) Make sure the power adaptor is connected to the bike Set the bike power switch to "off" and then remove the USB cable from the bike computer. NOTE! It is important that the USB cable is disconnected from the bike computer, otherwise there may be a conflict between the external computer and the display with integrated computer. Insert the supplied RS232 cable to the RS232 connector (2) below the RPM meter. At the other end of the RS232 cable, connect the USB serial adaptor. Connect the USB connector into an available port on the external computer. Set the bike power switch to "on" and then start the software in the external computer. If you connect an external computer with an RS232 port you can connect the RS232 cable directly into the serial port and do not need to use the USB serial adaptor. LC6/LC7 1 Fig: Connection 1) RS232 connection 13 Validation Validation of force The following procedure ensures that the bike works for daily use. Start the PC software and select a test programme from the menu "Test". In the dialogue box that opens is a box showing the braking force in Newton, see Fig: Force and HR display. You do not have to press "Start" (1) to get the heart rate showed (2), but you must press "Start" to show the force (3). • Check the pulse function, see section. • Check the brake force, see section. • Pedal and check that it obtained a reasonable rpm - verify by a clock. Feel so the pedals move smoothly. Listen for unusual sounds. Remedy if necessary. • Adjust the handlebar and saddle and make sure they are securely attached and that the adjustment is working properly. • Make sure the support legs are in position by rocking the bike. Tighten if necessary. If something unusual is found during the daily inspection and that you not can resolve, please call customer service. Checking the pulse function 1. With the pendulum pointer at 0, the display should read "00N". 2. Move the pendulum pointer to 4 kp and the display should now show "39N". If the braking force is not displayed correctly, an electronic calibration must be done. See section "Calibration electronics". NB: After this verification, the brake belt will be loose, which means that it takes about 15 seconds before the regulating device has tense the brake belt to normal again (5 N). This bike does not have a meter that shows the heart rate. However, the heart rate is displayed in the computer software or other external equipment. 1 2 While the patient rests, with the chest belt on, compare heart rate in the software with the manually taken pulse. If it does not correspond, check the chest belt contact area and moisten if necessary the electrode surfaces with water. If this fails, call customer service. Fig: Force and HR display 1) Start 2) Heart rate display 3) Force in software (manual test) Fig: Placement of the chest belt 14 LC6/LC7 3 Zero adjustment of scale Calibration Check that 0-index (3) on the scale (2) is in line with the pendulum pointer when the bike is at a stand still and the brake belt is loose. If not, an adjustment must be done. Loosen the screw and adjust the scale. Tighten the screw (1) after adjustment. See Fig: Adjustment scale. All LC6/LC7 are calibrated in the factory, but a calibration of the pendulum can still be done to verify this. If so, please do the following. Open the front cover. Check that the brake belt is loose. If not, move the pendulum to 4 kp and hold it there a while to loosen it. Unhook the brake belt from the spring. Check that scale 0-index is in line with the pointer. Adjust if necessary, see section "Zero adjustment of scale". Calibration weight 4 kg (Art. No: 9000-211) is hooked on the spring. NOTE! The flywheel must be completely stopped before the weight is hung on! 1 2 3 Fig: Adjusting scale 1) Screw 2) Scale (Kp-scale) 3) 0-index 1 2 3 This weight (4 kg) can, when properly adjusted, be read at the corresponding point on the scale. If there is a deviation adjust the pointer to the correct position by adjusting the weight inside the pendulum. To change the adjustment weight loosen the adjustment screw (1). If the pointer shows too low, the internal weight must be moved upwards. If the pointer shows too high, the adjustment weight is moved down. This process is repeated until pointer is in the correct position. Hook the brake belt in the spring and close the front cover. Check the calibration of the pendulum weight once a year or when needed. 4 4 kg 3 1 2 Fig: Calibration 1) Kp-scale 2) Pointer 3) Spring 4) Calibration weight 4 kg Fig: Pendulum 1) Adjustment screw 2) Adjustment weight 3) Brake belt LC6/LC7 15 Calibration Calibration electronics - with pendulum LC6/LC7 has a mechanical brake and pendulum weight, making performance validation a simple procedure. Calibration is necessary so that the electronic and the mechanical parts of the cycle conform. The work carried out on the bike is a result of the braking force (pendulum mode) and the number of pedal revolutions (= distance). The effect is then counted out by dividing the work done by the time it took to accomplish it. Validation includes both mechanical and electronic procedures. For detailed information, see the computer programme's user manual. If the bike fails to pass any section of the validation, proceed to the calibration and/or service menu. The following steps show how electronics are calibrated against the pendulum. After any repair or service, a "Daily Check" should be done. Calibration electronics Usually it is not necessary to recalibrate the cycle electronically, but it should be done after each service, change of electronic part, movement, if you adjusted the 0-index, or after you have programmed the "Reset" by default settings. The calibration coefficient calculated by the computer is stored in main memory. No matter when the power is turned on, the last stored calibration will be placed in main memory. New calibration automatically replaces the old. A check of the electronic calibration can be done in the computer programme, see section "Validation of force". 1. Open the front cover. 2. Check that the brake belt is loose on the flywheel, see Fig: Control loose brake belt. If not, move the pendulum pointer to 4 kp and hold it there for a few seconds. Move the pendulum pointer to 0 again, and check again that the brake belt is loose. 3. Adjust the scale, see "Zero adjustment of scale," so that the pendulum pointer is pointing at the 0-index of the scale, see Fig: Zero position. 4. Turn off the power to the bike and move the pendulum pointer to 4 kp, as shown in Fig: 4 kp. 5. Hold the pendulum pointer at 4 kp and turn the power on the bike again and wait for a beep. Move the pendulum pointer to 0, see Fig: 0 kp. Wait for a beep. 6. Move the pendulum pointer to 2 kp, see Fig: 2 kp. Wait for a beep. 7. Move the pendulum pointer to 4 kp, see Fig: 4 kp. Wait for a beep. 8. Move the pendulum pointer to 6 kp, see Fig: 6 kp. Wait for two beeps. Move the pendulum to 0 again. The calibration is complete. Close the front cover. It is also possible to calibrate from the software. See the menu "Monark Ergomedic" - Check calibration..." in the computer software. NOTE! The pendulum must be kept still at the different positions. This is done by pressing the pointer in the groove on the scale at each kp value. 16 LC6/LC7 Fig: Zero position Fig: Control loose brake belt Fig: 2 kp. Fig: 4 kp. Fig: 0 kp. Fig: 6 kp. LC6/LC7 17 Testing with LC6 / LC7 The versatility of the LC6 / LC7 enables it to be utilized in a variety of testing environments. The precision and reproducibility of the test values obtained with the bike, along with the uncomplicated way to set up the tests, means the bike can be used in clinical work tests, in occupational health services for the fitness tests as well as fitness centers, schools, sports clubs and the like. In general, one should note that stresses on the tested person can become quite severe, whether in a clinical work test or a simple fitness test in physical activity contexts. As a precaution, it may be advisable, prior to beginning an exercise protocol, that each subject consults with a physician. Before testing, the operator should review the entire protocol operation with the test person, explaining the work which will be required and the duration of the procedure. One should also agree on how the test person shall give signs of any fatigue, chest pain or other abnormal physical reactions. The test person should not engage in heavy physical activity for several hours prior to testing to establish maximum oxygen consumption. In addition, all testing and exercise protocols should be performed a reasonable time after meals. The test person should also refrain from smoking within an hour of the testing period. The tested person shall also have the appropriate clothing for a work test. Training suit or loosefitting clothing is best. More detailed instructions are rarely needed, regarding the ride, but it may still be appropriate for the test leader to give some advice on pedalling, saddle height and position of the handlebars. It should be comfortable to ride The appropriate height of the saddle is when the knee is slightly bent when the sole of the foot is centred over the pedal axle with the pedal to the bottom position. 18 Let the test subject try to ride with low workload and see how it feels to hold a steady rpm. Finally, the chest belt shall be put on, see Fig: Placement of the heart rate belt in section "Heart Rate (telemetry)" for correct placement. Check for a minute that a proper heart rate is displayed. The baseline heart rate may also be of assistance in determining the nervousness of the test subject. It may be appropriate to let the test person rest long enough before the test so a more or less stable resting heart rate can be read. Power calculation 1 rpm = that a point on the flywheel moves 6 meters per minute. 50 rpm = 300 m 2 kp force makes 2 x 300 = 600 kpm/min 100 rpm= 600 m 1 kp force makes 1 x 600 = 600 kpm/min Exact calculation: Watts = rpm x kp x 0.98065 "Rule of thumb" calculation: Watts x rpm x kp (2% error, but may be good enough in many cases) LC6/LC7 Heart Rate (telemetry) Test person enforcement A person's heart rate can be measured with a chest belt that senses the electronic output of the heart. The chest belt is standard equipment. The bike performs automated tests virtually by itself, requiring minimal intervention by the test operator. This allows the operator to pay careful attention to the test subject without distraction. The response to the exercise protocol can be accurately estimated and appropriate action taken to assist the test person, if necessary. Some programmes have sections where the test person may develop significant physical activity. The effect on the test person should not be underestimated. The bike does not have a meter that shows the heart rate, however, the HR is displayed in the computer programme or in other externally connected devices. The chest belt should be secured at a comfortable tension around the mid section, just below the breast muscle. Moisten the electrodes before use. Fuss-free HR measurement requires that the belt is correctly placed. When it is correctly fitted the logo on the belt will be central and readable, outward and upright, by another person. Before putting on the belt, clean the skin where the belt is to be placed. To make contact with the HR receiver on the bike, the distance should not be more than 100 cm. It is especially important when first used to identify the chest belt with the sensor, by standing close to get the HR (maximum 60 cm). This relates especially to the Polar heart rate belt. NOTE! Electromagnetic waves can interfere with the telemetry system. Cellular phones are not allowed to be used near the bike during test. During the test it is important to observe the subject person's appearance and heart rate. The testing should be stopped immediately if the test person reports chest pain, difficulty breathing, etc. A system of prompt medical attention should be set up prior to testing, in case of emergency. The test person may also have difficulty keeping a steady pedalling speed. This is of minor importance (except in cases where the program assumes a constant braking force, since the effect is automatically adjusted to the correct value as long as the pedal speed is at least 35 revolutions / min (rpm)). However, it is important to consider what each test documentation says about the pedal speed. In case of problems, turn off WiFi, Bluetooth and similar on computers nearby (including the display with integrated computer on LC7). Fig: Placement of the heart rate belt LC6/LC7 19 Reviewing results The maximum oxygen uptake is the standard measurement of cardiopulmonary fitness. Dependent on the linear relationship between work and oxygen uptake and between work and heart rate, the heart rate response to work may be used to estimate the oxygen consumption. If the maximum heart rate is considered, the maximum oxygen consumption may be determined. The YMCA and Åstrand protocols estimate the maximum oxygen consumption, based on a submaximal workload while all others report the oxygen consumption required by the final workload. The Bruce and Naughton protocols require that the test subject exercise at a workload level for a minimum of one minute to establish the oxygen consumption. If less than one minute is observed, the previous workload value is used. The estimated maximum oxygen consumption derived from some of the ergometer tests is subject to the error of the “age related predicted maximum heart rate“. Although there is a definite and linear relationship between work and oxygen uptake, there are some differences in actual oxygen uptake based on individual work efficiency. Test persons who are less familiar with bike exercise and those individuals who are less fit, are more likely be less efficient than those who ride bikes frequently. It should be noted that these results are estimates or predictions of maximal response and have a greater chance of being in error than if the individual were tested to their actual maximum value. Interpretation should therefore be made more carefully with an understanding of the possibility of errors in the methodology. A relative fitness index can be obtained from the following tables: Fitness Rating Index - Males Maximum Oxygen Consumption ml/kg/min Rating -36 yrs 36-45 45- yrs yrs Excellent 54 53 43 Good 49 45 38 Above aver- 46 39 34 age Average 36 33 30 Below aver- 32 29 27 age Fair 28 25 24 Poor 24 23 20 Fitness Rating Index - Females Maximum Oxygen Consumption ml/kg/min Rating -36 yrs 36-45 45- yrs yrs Excellent 55 49 46 Good 45 43 38 Above aver39 37 32 age Average 34 33 27 Below aver30 29 24 age Fair 26 26 20 Poor 20 22 18 See also table 7 in “ Work tests with the Bicycle Ergometer“ by P O Astrand. 20 LC6/LC7 Trouble shooting guide Symptoms Probable Cause/Corrective Action LED does not light up. • • • • No current in the outlet.

Try the belt with a person known to have a good pulse wearhing the chest belt. Check for loose cables or jack if you have a plug-in receiver. Use another HR receiver (HR watch or test bike monitor) to check the chestbelt. Check that it is the correct receiver and that it is in the correct place. Does it have a round Polar logo, the right way up. Uneven heart rate. • Use an external unit for example a HR watch to check if it also indicates irregular pulse. If this is the case, there is probably disturbance in the room. The disturbance may be of electronic fields from power cables, elevators, lamps etc. or other electronic devices which are too close (eg. cell phones). Move the bike to a different location in the room or change rooms. If an irregular HR remains it should be checked manually If the HR remains irregular at work the person's health should be examined. No rpm reading. • Check cable. Unable to calibrate force. • • The potentiometer shaft is not attached to the pendulum shaft, tighten the screw. The potentiometer is misadjusted. See the computer software menu - ’Monark Ergomedic’ - ’Service program...’ - ’Potentiometer’ and follow the instructions that appear on the screen. Then calibrate the electronics again. There is a click noise with every pedal revolution (increases with the weight). • • • The pedals are not tight. Tighten them or change pedals. The crank is loose. Check, tighten. The base bearing is loose. Contact your dealer for service. Scratching sound is heard when pedalling. • Check that the carriage block is taken off and that nothing is against the crank, chain, or wheel except the brake belt. There is a click noise and a squeak noise when pedalling. • Loosen the chain. LC6/LC7 21 Error message Message Cause "Test is aborted" An automatic test program has been stopped before it is ready, or with values that are outside the tables so that no result can be calculated. No test results can be obtained. Operation interferences It is normally considered that about 70 % of all shutdowns on small computers are caused by mains interferences, i.e. at short over voltage. These interferences can often be caused by different machinery, which is started or stopped. The processor in the computer is then reacting incorrectly or is not working at all. The problems can be solved by means of a mains interference protector, which is connected between the mains and the transformer. 22 LC6/LC7 Where to obtain additional information The user may require more information concerning several areas of the ergometer usage. This manual was intended to instruct the reader primarily in the operation of the ergometer. References are made to related topics in the discussions concerning the testing procedures and the protocol operation sections.

It is important to carry out a regular service on your ergometer, to ensure it is kept in good condition. Always keep the bike clean and well lubricated. Warning Service action: Make sure the voltage indicated on the appliance corresponds to the local mains voltage before making connections. • We recommend isopropyl alcohol to disinfect the surface of the bike. Use a damp but not wet cloth to clean the surface you wish to disinfect. • Surface treatment with a rust inhibitor, especially when the bike is clean and the surfaces are dry This is done to protect the chrome and zinc parts as well as the painted parts (4 times per year). Warranty EU countries - Private use If you are a consumer living in the EU you will have a minimum level of protection against defects in accordance with EC Directive 1999/44/EC. In short, the directive states that your Monark Dealer will be liable for any defects, which existed at the time of delivery. In case of defects, you will be entitled to have the defect remedied within a reasonable time, free of charge, by repair or replacement. EU countries - Professional use Monark Exercise products and parts are guaranteed against defects in materials and workmanship for a period of one year from the initial date of purchase of the unit. In the event of a defect in material or workmanship during that period, Monark Exercise will repair or replace the product. Monark Exercise will not, however, refund costs for labour or shipping. Other countries Monark Exercise products and parts are guaranteed against defects in materials and workmanship for a period of one year from the initial date of purchase of the unit. In the event of a defect in material or workmanship during that period above, Monark Exercise will repair or replace (at its option) the product. Monark Exercise will i.e. not refund costs for labour or shipping. • Check now and then that both pedals are firmly tightened. If not the threading in the pedal arms will be damaged. When the Ergometer is new it is important to tighten the pedals after 5 hours of pedalling (4 times per year). • Check that the pedal crank is secure to the crank axle (4 times per year). • Be sure that the pedals are moving smoothly, and that the pedal axle is clear of dirt and fibres (4 times per year). • When cleaning and lubricating be sure to check that all screws and nuts are properly tightened (twice a year). • Check that the chain is snug and there is no play in the pedal crank (twice a year). • Check that pedals, chain and freewheel sprocket are lubricated (twice a year). • Be sure that the brake belt does not show significant signs of wear (twice a year). • Check that the handlebars and seat adjustment screws are lubricated (2 times per year). • Be sure that all moving parts, crank and flywheel are working normally and that no abnormal play or sound exists. I.e. play in bearings causes fast wearing and with that follows a highly reduced lifetime. • Check that the flywheel is placed in the center and with plane rotation. • Grind the brake belt contact surface, see section "Brake belt contact surface" (once a year). 24 LC6/LC7 Batteries If the meter is battery-operated, the batteries are in a separate package at delivery. If the storing time has been long the battery power can be too low to make the computer act correctly. Batteries must then be changed. Manual pendulum bike / exercise bike: To loosen the brake belt on the bike remove all tension. Please note how the belt is assembled. Remove it from the bike. Attach the new brake belt and assemble the bike in reverse order. Crank bearing NOTE! When replacing the brake belt it is recommended to clean the brake surface. See ”Brake belt contact surface”. The crank bearing is long term greased and requires no supplementary lubrication. If a problem arises, please contact your Monark dealer. Flywheel bearing The bearings in the flywheel are lifetime greased and require normally no maintenance. If a problem arises, please contact your Monark dealer. Transport During transport the brake cord should be tightened to prevent it from falling off the flywheel. Replacement of brake belt To replace the brake belt remove covers if necessary. Make sure that the belt is loose. Pendulum bike with engine: To loosen the brake belt on pendulum bikes with engine, connect power to the unit and raise the pendulum to 4 kp. Hold it there until brake belt is loose. Please note how the belt is assembled. Remove it from the bike. Attach the new brake belt and assemble the bike in reverse order. Brake belt contact surface Deposits of dirt on the brake belt and on the contact surface may cause the unit to operate unevenly and will also wear down the brake belt. The contact surface of the flywheel should be smoothed with fine sandpaper and any dust removed with a clean dry cloth. Remove any potential covers and all workload on the brake belt and then remove it. Grind with a fine sand paper. Grinding is easier to perform if a second individual cautiously and carefully pedals the cycle. Irregularities on the brake belt contact surface are removed by means of a fine sand paper or an abrasive cloth. Otherwise unnecessary wear on the brake belt may occur and the unit can become noisy. Always keep the brake belt contact surface clean and dry. No lubricant should be used. We recommend replacing the brake belt when cleaning the contact surface. In regard to assembly and adjustment of the brake belt, see ”Replacement of brake belt”. Weight basket bike: To loosen the brake cord on cycles with a weight basket set the basket to its upper position. Loosen the lock washer that is holding the cord and remove it from the tension center. Loosen or cut of the knot in the other end of the cord and then remove the hole cord from the bike. When assembling a new brake cord, first enter one end into the hole in the tension center, and tie a knot and let the knot fall into the bigger part of the hole. Lock the end of the cord with the lock washer. LC6/LC7 Fig: Brake belt contact surface 25 Chain 1/2“ x 1/8“ Check the lubrication and tension of the chain at regular intervals. In the middle of its free length the chain should have a minimum play (3) of 10 mm (1/4 inch). See Fig: Chain adjustments. When the play in the chain is about 20 mm (3/4 inch) the chain must be tightened. Otherwise it will cause abnormal wear of the chain and sprockets. Therefore it is always recommended to keep the chain play as little as possible. Loosen the hub nut (2) on both sides and tense the chain with the chain adjuster (1) when needed. When the chain has become so long that it can no longer be tightened with the chain adjusters it is worn out and should be replaced with a new one. 1 2 3 Fig: Chain adjustments 1) Chain adjuster 2) Axle nut 3) Chain play To replace the brake belt, remove covers as required. To adjust the chain the hub nuts (2) should be loosened. Loosening or tightening the nuts on the chain adjusters (1) will then move the hub and axle forward or backward. Then tighten the nuts on the hub axle again. See Fig: Chain adjustments. To replace the chain, loosen the chain adjusters as much as possible. Dismantle the chain lock(6) and remove the chain. Use a pair of tongs for dismantling spring. Put on a new chain and assemble the chain lock. The spring of the chain lock should be assembled with the closed end in the movement direction (5) of the chain. Use a pair of tongs for dismantling and assembling the spring (4). See Fig: Chain replacement. NOTE! At assembly the flywheel has to be parallell with the centerline of the frame. Otherwise the chain and chain wheels make a lot of noise and wear out rapidly. Then assemble the removed parts as above but in reverse order. 26 LC6/LC7 5 6 4 Fig: Chain replacement 4) Lock spring 5) Movement direction 6) Chain lock Freewheel sprocket When replacing the freewheel sprocket remove frame covers if necessary. Remove the chain according to section ”Chain 1/2” x 1/8””. Loosen the axle nuts and lift off the flywheel. Remove the axle nut, washer, chain adjuster and spacer on the freewheel side. Place the special remover (Art. No: 9100-14) in the adaptor and place the spacer and axle nut outside. See Fig: Special remover. NOTE! NOTE: Do not tighten the axle nut completely. It must be possible to loosen the adaptor-sprocket half a turn. Replace sprocket-adaptor and assemble the new parts in reverse order according to the above. The sprocket should be lubricated with a few drops of oil once a year. Tilt the cycle to make it easier for the oil to reach the bearing. See Fig: Lubrication.
