VENT PLUG INSTALLATION
Gear reducers used in OSCO gate operators will have solid plugs installed prior to shipment in order to keep the oil inside from
spilling out during shipping. A vent plug has been provided to replace this plug during installation. This plug will look similar to
the ones shown below. Some models may have a vent plug with a breather pin. This pin should be removed after installing the
operator.

OPTIONAL TORQUE LIMITER
ADJUSTMENTS
Your Model SLR, SLC or SLD may have an optional torque limiter.
Follow these instructions if you do.
Before adjusting the torque limiter, make sure the gate is in good
working condition. One person should be able to move the gate by
hand. Be certain the gate moves freely and without binding through-
out its travel. Torque limiters are set light at the factory and must be
adjusted during installation. Adjust the torque limiter tight enough to
keep it from slipping during normal operation.
To adjust the torque limiter in models SLR, SLC and SLD:
1. Bend the locking tabs away from the adjustment nut.
2. To increase the output, turn the adjustment nut clockwise one
flat, or 1/6 turn, at a time until desired output is obtained.
To reduce the output, turn the adjustment nut counterclockwise
one flat, or 1/6 turn, at a time until desired output is obtained.
3. Bend the locking tabs up to lock the adjustment nut in place.
