1. Clutch
Before any modification on the winch, shut off the tractor engine!
Pulling force on the clutch is factory set and does not require to be changed. Due to
wear of friction surfaces, distance between clutches needs to be set after a certain
period. This is done once a year at usual work in the forest or after every 1000 m
3
of pulled
out logs, but not before end of warranty period. Perform the setting by unscrewing the nut
(pos. 9, figure 11), which is the safety nut, to the left. Then, tighten the high nut (p
os. 15,
figure 11) to the right. In this position, there is no distance between the clutches. Then,
unwind the nut for one turn to the left
–
this creates a gap between the lamellas of
approximately 4-
5 mm. Retighten the safety nut (pos. 9, figure 11) to the
right. This protects
the high nut from unwinding. Engage the motor and PTO shaft, pull out the rope and
begin controlling the adjustment. If, despite not engaging the right button for pulling, the
rope starts to move, then the distance between the clutches is too small. Increase it for
approximately 1 millimeter or repeat the setting procedure by unwinding the high nut for
¼ of a turn to the left. Engaging pulling is not allowed, if the nuts (pos. 9 and 15, figure 11)
are not installed on the shaft, because the hydraulic cylinder of the clutch gets damages,
because the maximum permitted travel is only 8 mm!
WARNING
For cylinder travel greater than 8 mm, oil can leak down the clutches.
2. Preliminary brake
With bol
t (pos. 4, figure 11) and wing nut (pos. 5, figure 11) set the preliminary brake.
By
rotating the bolt to the right, the brake force is increased, with rotating to the left, the
brake force is decreased. Then tighten the wing nut, which prevents the bolt to loosen
automatically. Proper setting ensures that the wire rope does not roll off the drum
automatically or excessively. This would cause loose winding and damage to the wire
rope at fast disburdening of the brake and unwinding. Preliminary brake is properly set
when unwinding of the rope is still possible without excessive effort. If you pull the rope
uphill, it is possible to additionally disburden the brake, so that rope towing is easier, the
bolt (pos. 4, figure 11) must be returned to its original posit
ion immediately after.
