MAINTENANCE OF YOUR OPENER SYSTEM
Test door opener monthly. The garage door MUST reverse on contact with a 1 inch high solid test ob-
ject on the floor. If adjusting either the force or the limit of travel, retest the door opener. Failure to ad-
just the opener properly may cause severe injury of death.
KEEP GARAGE DOORS PROPERLY BALANCED. See owner’s manual. An improperly balanced door
could cause severe injury or death. Have a qualified service person make repairs to cables, spring as-
semblies and other hardware.
Once a Month:
1.
Manually operate door, if unbalanced or binding, call a professional garage door service person.
2.
Check to be sure door opens and closes fully. Adjust Limits and/or Force, (
see pages 17, 19 and 21).
3.
Perform safety reverse tests (Step 28 and 30). Make any necessary adjustments.
Twice a Year:
Check chain tension. If chain rests on bottom of rail, adjust tension by turning the two chain adjusting nuts at the end
of the rails (
opposite the power head end)
clockwise. Make sure to adjust both nuts equal amounts and adjust until
chain is approximately 5/8” above rails. If your opener is equipped with only a single nut simply turn the nut to adjust
the rail.
Once a Year:
1.
Lubricate door rollers, bearings and hinges. (
Refer to door owner’s manual for maintenance information)
.
2.
Check batteries in Transmitters, Wireless Wall Station, Wireless Keyless Entry and Wireless Infrared Safety Sen-
sors (
if included)
. When replacing batteries always use new batteries; never mix old and new batteries. Never mix
different types of batteries (
see pages 14, 17 and 20)
. Alkaline or Lithium batteries are recommended for longer
life. Dispose of used batteries properly.
