CUTTING UNIT

Cutting unit
Dismantling
The cutting unit is a separate unit that can be replaced.
Remove the first water hose at the water valve. Remove the four screws that
hold the cutting unit to the crankcase.
Lift off the cutting unit.
Lock washers
The cutting machine is subjected to large vibration forces during operation.
Three of the cutting unit's attachment points to the crankcase are therefore
fitted with a special type of lock washer (Nord-Lock) that ensures secure
locking, provided they are fitted with the correct torque. The washers must
not be forgotten or replaced by other types of washer when reassembling.
Fit – use the torque wrench
In order for the Nord-Lock washers to provide secure locking, the two nuts
and the screw must be tightened at a specific torque. This must be done with a
torque wrench: Torque 26–30 Nm/19–22 lbf·ft.
The small screw, without a washer, must be treated with Loctite thread locking
compound and tightened to 10-13 Nm/7-10 lbf·ft.
