(a) Engage the winch drum lock.
(b) Place the winch clutch lever in the FREE position.
(c) Loosen lock nuts (1), loosen adjusting bolts (2, 3 and 4) so that the clutch band does not contact the head of the adjusting bolts.
(d) Adjust dead end adjusting bolt (3) in the dead end of the clutch band so that the clearance
between the drum and the clutch lining becomes approximately 0.6mm (0.024").
In the same way, adjust adjusting bolt (4) in the live end so that the clearance becomes approximately 1.Omm (0.04").
(e) Turn push rod (5) so that wheel cylinder (6) is retracted completely when the clutch is released.
