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 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 operator comes with two 7AH batteries. Two 33AH
(A12330SGLPK), with 33AH Battery Harness (K94-36596) may be used in place of
the 7AH batteries.
The batteries contain lead and need to be disposed of properly.

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.
