Without a properly installed safety reversal system, person (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 BE TESTED. Gate MUST
reverse on contact with a rigid object.
The opener is equipped with an obstruction sensing feature. If the gate encounters an obstruction the opener will
automatically reverse direction 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.
NOTE:
You may need to increase the stall force in cold weather due to increased resistance from
gate hinges. The gate opener’s opening/closing force is adjusted automatically according to stall force
adjustment.
