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 requires a torque value of 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 tightening may cause cable failure.
SETTING THE CLUTCH UNDER FIELD CONDITIONS
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 direction ap-
proximately 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.
