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
If the cylinder stroke is greater than 8 mm, oil can leak on clutches.
Preliminary brake
Set the pre-
brake with screw (pos. 4, fig. 11) and nut (pos. 5, fig. 11).
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 position immediately after.
