5.6.1 Clutch
Before attempting any intervention, make sure to first switch the tractor engine off and
remove the ignition key!
Proper clutch settings will ensure optimum pull force. The clutch is set by the manufacturer during
final testing of the product before shipment. However, possible wear of the lining may require some
extent of adjustment as the time passes. Clutch adjustment should be performed every time when
your winch no longer reaches the required pull force.
To perform clutch adjustment:
• loosen the nut shown in Pos. 1
• slightly tighten the nut in Pos. 2
• on engaging of the clutch, switch the motor on and start the driveline
• if the rope winds up although you are not pressing the black push-button (1), then you probably
tightened the nut (Pos. 7) excessively and there is no more clearance between the drum and the
clutch. In this case, release the nut and repeat the setting procedure till the rope stops winding
unless the black push-button is pressed.
5.6.2 Prebrake regulation
To facilitate winding of the wire rope, perform prebrake regulation with the screw (10) and respective
wingnut (11) (Fig. 8). Exact prebrake regulation will also prevent the rope from unwinding excessively
fast or accidentally slipping off the drum. Extreme fast unwinding and abrupt brake disengagement
may cause severe damages to the wire rope. Exact prebrake regulation occurs when the rope can be
effortless spooled off the drum. The prebrake arrangement must be disengaged for uphill winching
operations in order to ensure easier pulling of the rope. A pre-braking function is also performed
by the inlet fairlead Pos. 12, (Fig. 8) where the rope is inserted. Exact prebrake regulation will also
prevent the rope from unwinding excessively fast or accidentally slipping off the drum. Extreme fast
unwinding and abrupt brake disengagement may cause severe damages to the wire rope.
Exact prebrake regulation occurs when the rope can be effortless spooled off the drum.
The prebrake arrangement must be disengaged for uphill winching operations in order to ensure
easier pulling of the rope.
5.6.3 Brake
On completed pulling, the differential brake automatically takes the load over (the drum should not be
allowed to unspool and the rope must remain stretched).
The brake is preset by the manufacturer before shipment. However, it is possible that slight wear of
the brake band lining occurs requesting some additional adjustment. Brake readjustment must be
performed every time when the load cannot efficiently hold back any longer.
To perform readjustment:
• tighten the nut (Pos. 3) Fig.8 used to lock the spring
• adjust nuts (3) and (4) to obtain a 7 mm gap between nut (1) and (3) on the threaded spindle
• tighten nut (4) to complete the procedure
