Safety Information CombCut should be connected to an ordinary tractor. Machine should be used for cutting weed in growing culture. CombCut is delivered from factory in folded transport position. When off-loading the machine must be placed on an even and hard surface, otherwise there is a risk that the machine can fall over. After offloading must be unfolded and stored in unfolded position. See information about parking. WARNING! Read and understand this manual before start using the machine.
WARNING! Never attempt to work on or repair the machine when tractor engine is on. There is a risk that the hydraulic system can be activated. WARNING! The operator must make sure there is no person close to the machines working area. This is also valid when folding and unfolding CombCut hydraulicaly. VARNING! Never allow anyone to sit or climb on the machine.
WARNING! RISK OF CUTS The machine has a large number of razor sharp cutting blades at the bottom of the frame. The blades must, during transport, repair, lubrication, cleaning or adjusting, be covered by the orange protective plates. These plates are fitted with warning decals for cutting risk. WARNING! RISK OF CRUSH INJURIES When the 8 meter machine is folded together and disconnected from the tractor, there is a risk that the machine can fall over, if it’s lending more than 6 degrees. It is VERY important to place the machine on an even hard surface. WARNING! RISK OF CRUSH INJURIES When folding out the machine from transport position there is a risk of crush injuries. The operator must make sure that no person is close or under the machine. There is also a risk of crush injuries when folding or unfolding the outer sections on the 8 meter machine. Warning decals for crush injuries are fitted on the machine near the risk zone.

WARNING! RISK OF CRUSH INJURIES When using the brushes there is a risk of crushing injuries. The operator must make sure there is no person close to the machine when the brushes are activated. Warning decals for rotating parts are fitted on the machine in the vicinity of the risk zone. NOTE ! Lowest hight is 2.8m when CombCut is folded together (depending how high it’s lifted from the tractor). Transport width is 3m, when machine is folded together. Weight is 800kg (6m version) and 1050kg (8m version) (Wheight w/o wheels). Wheel incl. bracket, wheight 27,5 kg per wheel. Recommended air pressure in the tires is 4 bar, max pressure is 5 bar. Before transportation of CombCut both outer sections mist be folded in and locked (8m version). Both side sections must after this be folded up and secured against the rest position BEFORE transportation. Hydraulic hoses must be changed if they are damaged or have signs of cracks. Risk of hydraulic oil leakage. When lifting the machine, only use the red marked lifting lugs, located on top of the mid section frame. The lifting lugs are also labelled with decals showing a lifting hook
Important Technical Information NOTE! Before making any work or repair on the machine the hydraulic hoses must be disconnected from the tractor. All 4 hydraulic connections must be disconnected. CombCut must be safely connected to the tractors 3-point linkage or placed on an even hard surface. Use the legs and wheels on the machine and make sure it’s standing in a stabile position.

Always start adjusting the outer section. Tilting of knives: (Adjustment 0-15 on the indicator)
Risk of cutting
Tilting of knives is adjusted by turnbuckle “A”. Factory setting: 5 on the indicator. Adjustment: Loosen the lock nuts on turnbuckle ”A”. Adjust the length of the turnbuckle. Wrench size 19 mm. The topp late is now moved sideways. Higher value on the indicator means more distance between the knifes. More material will pass through the knifes. Less cut material. Indicator at ”0” means that the knives are completely closed and all material is cut. Tighten the lock nuts. Adjust all sections to the same indication value. See section ”Practical hints”. Angle of attack: (Adjustment 40-70 on the indicator)
Risk of cutting.
Adjusted by turnbuckle “B”. Factory setting: 50 on the indicator. Adjustment: Loosen the lock nuts on turnbuckle “B”. Adjust the length of the turnbuckle. Wrench size 19 mm. The under plate is now moved sideways. Higher value on the indicator means more aggressive cutting (specially if the weed straws are stiff). Tighten the lock nuts. Adjust all sections to the same indication value. See section ”Practical hints”.

Bolts 1; 2 och 3 are pre-adjusted with spring washers from factory. Plates 4 (top plate) and 5 (under plate) is moving sideways when the turnbuckles are adjusted. Bolts 1; 2 and 3 keep a constant spring pressure on all knives. 6
Tilting of machine Make sure no person is close to the machine. Risk of crush injuries Tilting of machine is done with the top link. Cutting hight is changed. A few degrees forward tilting could be advantageus to optimize the cutting result. Hydraulic top link is recommended if tilting of machine is adjusted frequently. See section ”Practical hints”
2-30 degrees
Hydraulic drive of the brushes.
Warning, rotating parts.
The brushes are driven by a hydraulic motor on CombCut’s right side. The hydraulic hoses are connected to the tractor’s hydraulic system. Red marking=pressure. Blue marking=Return. These two hydraulic hoses regulates the rotation direction of the brushes, both forward and reverse. The flow is controlled from the tractor. Rotation forward is normal operation. Reverser rotation is used when cut material need to be cleaned from the knifes. Cleaning is only done when needed and in short sequences (5-10 sek). Rotation speed of the brushes (approx 250 rpm) is pre-adjusted from factory and should normally not be adjusted.
Forward
Normal operation, forward rotation

Arms for brushes. 3 settings
Risk of cuts.
There are 3 positions for the support arms. The center shaft for the brushes must always be ”in line”, so the claw couplings will have a good grip. The claw couplings is the connection between the shafts. The support arms are mounted in the middle position from factory (Brushes moved towards the front). Brushes can be moved to achieve the optimum cutting effect. All brushes must be moved equally and the center shaft must be “in line”. If needed, also the turnbuckles and the bearing supports must be adjusted. After adjustment, make sure all bolts, arms and turnbuckles are securely tightened.

Adjustment of center shaft with claw couplings
Risk of crush injuries and cuts.
1) Start with the right outer section where the hydraulic motor is placed. 2) Loosen the bolts A on the arms , 2 pc. 3) Release the lock nuts B on the turnbuckles. 4) If needed, loosen the bolts for the bearing housings C (2 x 4 bolts) 5) Adjust to new position and tighten all bolts and nuts. Adjust all center shafts so they are “in line” with the shaft from the hydraulic motor. If this adjustment is not correct, there is a risk that the machine and brushes will create vibrations, harming the claw couplings and optimal function of the machine.

Brushes
When the side sections are folded out there is a risk to damage the claw couplings. Make sure the claws slide into correct position. Adjust by rotating the brushes slightly. The locking pins in the claw couplings can shear off if the shaft rotation is overloaded. It must then be replaced. The locking pins are purposly the weakest link and a safety to avoid serious damage on the machine. Folding to transport position.
Risk of crush injuries
CombCut has 2 hydraulic cylinders for folding the side sections to transport position. Before disconnecting the machine from the tractor it must be folded out and placed on an even hard surface 2 hydraulic hoses from the hydraulic pistons (marked black) is connected to the hydraulic system of the tractor. Folding up/out is then controlled from the tractor. Make sure no person is close or under the machine when folded. Risk of crush injuries. When transporting on a public road, CombCut must be placed behind the tractor. If you need to mount the machine in front of the tractor, CombCut must first be folded out and placed on an even hard surface, before disconnecting from the rear of the tractor (transport position).

Mounting CombCut on tractor.
Risk of crush injuries
3-point linkage for mount behind tractor
When transporting on a public road, CombCut must be placed behind the tractor. Use correct size bolts and pins for lifting arms and top link. CombCut 8m machine must have the outer sections folded and locked in transport position before folding up the side sections. Risk of crush injuries. Fold up the machine and make sure that the side sections are secured against the rest position BEFORE transportation Machine with side sections in high position should never be disconnected from the tractor. There is a risk that the machine will tip over. Make sure that functional and legal signs and lights are mounted before road transportation. Variations in regulations apply in different markets. Parking CombCut on an even and hard surface: Risk of crush injuries and cuts Make sure all protection plates for the knifes are mounted. Risk of cuts. Put the front legs in position. Foot pointing to the rear. Make sure the machine is as low down as possible. Secure the legs with bolt and safety pin. Put the wheels in highest position (lowering the machine as much as possible). Secure with bolt and pin. Make sure the wheels are pointing straight backwards (for best stability). If wheels are not used, put down the rear legs instead. The foot must point to the rear. Secure with bolt and pin.

Support foot poining backwards
Make sure there are no people around. Risk of crushing injuries when machine is folded out. Choose a place where the ground is even and stabile. When CombCut is folded out and is standing safely on a stabile surface on its legs, the hydraulic hoses can be disconnected from the tractor. Make sure there is no oil leakage. Disconnect the top link and the lifting arms and make sure the machine is standing in a stabile position and is folded out in full width. If you are using a hight extension adaptor, this must be disconnected from the machine, before parking CombCut. CombCut in parking position Front legs in parking position

Loading and off-loading CombCut At delivery CombCut is loaded in folded position. The red marked lifting lugs should be used for off loading. Since the machine is high when it’s folded there is a risk of falling. CombCut must be placed on an even hard surface, before folding it out. After off-loading CombCut must be parked in folded down position. The machine should only be folded up when securely mounted on a tractor for transport.

Parking
Don’t climb on the machine, risk of falling CombCut is delivered in folded position and is very high, causing risk of tipping over. This is specially important for the 8m machine. It’s important to park the machine on an even and hard surface, so the machine can be connected to a tractor and be folded down. CombCut is always parked in folded down position when not in use.
