CLUTCH ADJUSTMENT
Important: Always turn power o before making any adjustment.
Remove the two set screws in the clutch adjuster nut.1.
Using a 1 ¼” Open-end wrench (available at the factory) tighten the clutch adjuster nut until proper tension 2.
is achieved. (See Note below) Try just a ¼ turn at a time and then test. DO NOT USE A PIPE WRENCH OR
CHANNEL LOCKS TO ADJUST THE CLUTCH!.
Important: Do not over tighten the clutch! Gear damage may result voiding the warranty!
Note: e clutch must be suciently tight so that it does not slip in normal operation and so that the motor
and the current sensor “feel” a load when the gate is obstructed.
Aer the clutch is properly adjusted, with power OFF, tighten the two set screws in the clutch adjuster nut.3.
FINAL LIMIT ADJUSTMENT
It is possible that a nal adjustment may be required for the arm to stop exactly as desired. In the open position,
the swing arms and the pipe arm should be doubled on the top of each other. On CLOSE the motor should
turn o before the arm hits the stop so that it coasts to the stop. If the operation is not as described, adjust the
position of the limit collar to correct the error.

CLOSE TIMER
is switch is used to activate (on) or deactivate (o) the automatic close timer. e gate will
close aer a specied time as set under Close Delay if this switch is ON unless the gate is
being held open by an accessory.
Brake Delay (for slide gates only)
is set of switches determines the length of time between the motor turning o and the
electronic brake coming on. All switches should be ON except for a gate on an incline.
REVERSE DELAY
is set of switches is to prevent instant reversal of the motor to reduce operator/gate stress
and to prevent operator malfunction. Note: Never put all of these switches in the OFF position as
operator damage may result.
