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.
• 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 it is
within ten percent of the operator’s rating.
Disconnect all power (AC, solar, battery) to the operator before servicing. The operator's AC Power switch ONLY turns off AC power to the control board and
DOES NOT turn off battery power. ALWAYS disconnect the batteries to service the operator.
BATTERIES
Batteries will degrade over time depending on temperature and usage. For best
performance, the batteries should be replaced every 3 years. Use only LiftMaster
part 29-NP712 for replacement batteries. The operator comes with two 7AH
batteries. Two 33AH (A12330SGLPK) may be used in place of the 7AH batteries.
The batteries contain lead and need to be disposed of properly. Batteries do not
perform well in extremely cold temperatures.
The operator alarm will beep 3 times with a command if the battery is low.
DRIVE CHAIN
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.
NOTE: The chain should have no more than 1 inch of sag for every 10 feet of chain
length.
