To reduce the risk of SEVERE INJURY or DEATH:
• Disconnect ALL electric and battery power BEFORE performing ANY service
or maintenance.
• Without a properly installed safety reversal system, persons (particularly small children)
could be SERIOUSLY INJURED or KILLED by a closing gate.
• Too much force on gate will interfere with proper operation of safety
reversal system.
• NEVER increase force beyond minimum amount required to close gate.
• NEVER use force adjustments to compensate for a binding or sticking gate.
• If one control (force or travel limits) is adjusted, the other control may also need
adjustment.
• After ANY adjustments are made, the safety reversal system MUST be tested. Gate MUST
reverse on contact with a rigid object.
• READ AND FOLLOW ALL INSTRUCTIONS.
• ANY maintenance to the operator or in the area near the operator MUST NOT be
performed until disconnecting the electrical power and locking-out the power via the
operator power switch. Upon completion of maintenance the area MUST be cleared and
secured, at that time the unit may be returned to service.
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly
grounded and connected in accordance with local electrical codes.
NOTE: The operator should be on a separate fused line of adequate capacity.
• NEVER let children operate or play with gate controls. Keep the remote control away
from children.
• ALWAYS keep people and objects away from the gate. NO ONE SHOULD CROSS THE
PATH OF THE MOVING GATE.
• Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or
stop when an object activates the non-contact sensors. After adjusting the force or the
limit of travel, retest the gate operator. Failure to adjust and retest the gate operator
properly can increase the risk of INJURY or DEATH.
• Activate gate ONLY when it can be seen clearly, is properly adjusted and there
are no obstructions to gate travel.

LEARN LIMIT ASSEMBLY
The limits are internal settings that indicate when the gate is in the fully open position and the fully closed position. For proper functionality, the limits must be programmed during the
installation process. The gate has to travel a minimum of 6 feet in order to program the limits.
The programming uses a combination of buttons on the control board. The specific buttons used for programming depends on which side of the gate the primary operator is installed and how
many operators the installation includes.
BEFORE programming the limits ensure that the gate is closed and the chain is connected to the operator. To close the gate press the reset switch to RESET/DISCONNECT, then manually close the
gate. To resume normal operation press the reset switch back to NORMAL OPERATION.

FORCE ADJUSTMENT
The operator is equipped with an obstruction sensing feature. If the gate encounters an
obstruction the operator will automatically reverse direction for a short time and stop. Based
on the length and weight of the gate it may be necessary to make force adjustments. The
force adjustment should be high enough that small objects such as branches or wind will not
cause nuisance interruptions but low enough to prevent serious injury to a person or a vehicle.
Use the SINGLE BUTTON to open and close the gate.
If the gate stops or reverses before reaching the fully open or closed position increase the
force by turning the force control clockwise.
If the gate hits a rigid object and does not stop or reverse, decrease the force by turning the
force control counterclockwise.
Run operator through a complete cycle and verify proper operation.
NOTE: Weather conditions can affect the gate movement, so seasonal adjustment may be
required. The force control is factory set to the mid-position.
