The SL-150 AC gearbox is equipped with an internal clutch to protect the operator when gate is
reversed in mid-cycle.
The clutch comes from the factory set at 60 lbs. of torque. In some applications, where the gates are
heavier than normal, the clutch may require some adjustment to increase the amount of torque. It is
important to have the clutch tight enough to be able to move the gate without slipping. It is as important to
not over tighten the clutch, as it is a method of protecting the operator.
Follow these instructions to tighten the clutch when necessary:
Ÿ
To increase the torque, use a pipe wrench to turn the clutch nut clockwise.
Ÿ
Turn the nut 1/2 a turn at a time until the operator is able to move the load of the gate without the
clutch slipping.
Ÿ
Once the operator is able to move the gate without the clutch slipping, turn the nut one full turn. This
will allow the operator to move the gate, but also slip when the gate is reversed mid cycle or in the
event the gate gets jammed.
