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.
