NOTES:
• Severe or high cycle usage will require more frequent maintenance checks.
• Limits may have to be reset after any major drive chain adjustments.
• If lubricating chain, use only lithium spray. Never use grease or silicone spray.
• Over time, the drive chain on the operator will stretch and need to be tightened. To tighten the drive chain adjust either of the two chain eye bolts.
The chain should have no more than 1 inch of sag for every 10 feet of chain length.
• It is suggested that while at the site voltage readings be taken at the operator. Using a digital voltmeter, verify that the incoming voltage to the
operator is within ten percent of the operator’s rating.

Disconnect all power to the operator before servicing.

MAINTENANCE
To reduce the risk of SEVERE INJURY or DEATH:
• 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 (AC
or solar and battery) 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
national and 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.
• The entrance is for vehicles ONLY. Pedestrians MUST use separate
entrance.
• Test the gate operator monthly. The gate MUST reverse on contact
with a rigid object or reverse 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.
• Use the manual disconnect release ONLY when the gate is NOT
moving.
• KEEP GATES PROPERLY MAINTAINED. Read the owner’s manual.
Have a qualified service person make repairs to gate hardware.
• ALL maintenance MUST be performed by a LiftMaster professional.
• Activate gate ONLY when it can be seen clearly, is properly adjusted
and there are no obstructions to gate travel.
• SAVE THESE INSTRUCTIONS.
IMPORTANT SAFETY INFORMATION
To protect against fire and electrocution:
• DISCONNECT power (AC or solar and battery) BEFORE installing or
servicing operator.
For continued protection against fire:
• Replace ONLY with fuse of same type and rating.
