PURPOSE
1. Adjustment of the winch clutch nut is necessary to limit the power of the winch. The
clutch nut must be tight enough to prevent clutch slippage when raising the tower and loose
enough so that the clutch does slip if the tower should come in contact with some overhead
obstruction or be extended past the upper limit switch which would cause the tower to stop
against the dead stop bolt.
2. The clutch nut torque value is approximately 28 to 30 in lbs. (DO NOT OVER TIGHTEN)
NOTE: The nut may seem loose when it is properly set. DO NOT ADJUST; further tighten-
ing may cause cable failure.
INSTRUCTIONS FOR SETTING THE CLUTCH UNDER FIELD CONDITIONS WITHOUT
A TORQUE WRENCH
1. Loosen clutch nut approximately ½ turn.
2. Stand clear of the tower when raising or lowering tower.
3. Start engine and operate the winch in the up direction. The winch should run but the
tower should not move. (At this time the clutch nut should be loose enough to let the
clutch slip, if not, back off the clutch nut just enough so the clutch does slip).
4. Start the clutch nut setting procedure by making a slight tightening adjustment until the
tower starts to rise.
5. The tower may again stall even while the winch continues to run. If so, lower the tower
and make another slight adjustment to the clutch nut, by tightening in the clockwise direc-
tion approximately 10 to 20 degrees.
6. Repeat the previous step until the tower reaches full elevation without stalling. Do not
make large adjustments to the clutch nut as it would be easy to over tighten the nut.
7. Run the tower up and down at least 5 times to ensure consistent full elevation.
8. The clutch is a serviceable part and may require slight adjustments periodically.
