9.7 Adjust the Clutch
IMPORTANT! The clutch function is set at the factory.
Adjustment should not usually be necessary. The clutch
is designed to slip when the machine pulls the maximum
weight. Adjustment of the clutch changes the maximum pull
capacity of the machine.
If it is necessary to adjust the clutch:
1. On the front of the machine, loosen the three jam nuts.
2. Tighten the socket-head capscrews by hand until they
slightly contact the pressure plates.
3. Equally tighten the socket-head capscrews (in a pattern)
until the clutch lever moves freely.
Pull the cable or winch rope to feel the movement in the
clutch and adjust as necessary.
4. Tighten the three jam nuts.
5. Check the clutch setting.
6. Start the PTO and check for resistance on the clutch.
Resistance can cause the cable or winch rope to wind
slowly when there is no tension on the cable or winch
rope. If the cable or winch rope winds when the clutch is
disengaged, do the previous procedure again.

9.8 Drum Brake Maintenance
Set the drum brake to prevent the winch drum from turning and
the cable or winch rope from becoming tangled.
9.8.1 Drum Brake Operation
The drum brake has two positions:
• Engaged
When there is no tension on the cable or winch rope, the
spring moves the drum-brake arm to engage the drum
brake. The drum brake applies a small amount of tension on
the cable or winch rope.
• Disengaged
When there is tension on the cable or winch rope, the cable
or winch rope applies force to the roller. The drum-brake
arm moves to disengage the drum brake.
The cable or winch rope routing is between the drum-brake arm
and over the roller.
