5. Gear Reducer
If physical signs show a seal has broken in the gear reducer, it may be necessary to replace
the reducer.
When replacing the gear reducer oil, use Mobil1 10W-30 synthetic oil or equivalent. The oil
level for the gear reducer allows gear to be dipped but not submerged in oil.
DO NOT overfill gear reducer oil reservoir.

General Reference Information
THE GATE
Double check the gate and its related hardware. Does the gate move freely? If it doesn’t, this can
affect the internal obstruction sensor.
WIRING DIAGRAM
Always reference the wiring diagram that was supplied with the operator. Note that some of the
accessory items may have their own wiring diagram.
If you cannot correct the problem or if you feel you will require technical assistance, contact your
local distributor or dealer. If you do not have a distributor or dealer, then contact us for technical
assistance. Please when calling for assistance, make sure you have the gate operator model
number, voltage, phase, horsepower and a list of all accessories that are attached to the operator.
Features and Program Troubleshooting Review
The internal obstruction sensor (r.p.m. sensor) will cause the operator to either stop or reverse if it
senses a slow down in gate speed. A damaged or poorly working gate can trip the sensor and cause
“phantom” reversing or stopping.
