IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of SEVERE INJURY or DEATH:
l
READ AND FOLLOW ALL INSTRUCTIONS.
l
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.
l
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.
l
NEVER let children operate or play with gate controls. Keep the
remote control away from children.
l
ALWAYS keep people and objects away from the gate. NO ONE
SHOULD CROSS THE PATH OF THE MOVING GATE.
l
The entrance is for vehicles ONLY. Pedestrians MUST use separate
entrance.
l
Test the gate operator monthly. The gate MUST reverse on contact
with an object or reverse when an object activates the noncontact
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.
l
Use the manual disconnect release ONLY when the gate is NOT
moving.
l
KEEP GATES PROPERLY MAINTAINED. Read the owner’s manual.
Have a qualified service person make repairs to gate hardware.
l
ALL maintenance MUST be performed by a LiftMaster professional.
l
Activate gate ONLY when it can be seen clearly, is properly adjusted
and there are no obstructions to gate travel.
l
To reduce the risk of FIRE or INJURY to persons use ONLY LiftMaster
part 29-NP712 for replacement batteries.
l
SAVE THESE INSTRUCTIONS.
l
ALWAYS wear protective gloves and eye protection when changing the battery or working around the battery compartment.

NOTES:
l
Severe or high cycle usage will require more frequent maintenance checks.
l
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.
Batteries
Batteries will degrade over time depending on temperature and usage. The operator alarm will beep 3 times with a command if the battery is low. Batteries
do not perform well in extremely cold temperatures. For best performance, the batteries should be replaced every 3 years. Use only LiftMaster part
29-NP712 for replacement batteries. The batteries contain lead and need to be disposed of properly.
The standard control box comes with two 7AH batteries.
