CARE OF YOUR OPENER
LIMIT AND FORCE ADJUSTMENTS:
Weather conditions may cause
some minor changes in door
operation requiring some
re-adjustments, particularly
during the first year of
operation.
Pages 23 and 24 refer to the
limit and force adjustments.
Only a screwdriver is required.
Follow the instructions
carefully.
Repeat the safety reverse test (Adjustment Step 3,
page 25) after any adjustment of limits or force.
MAINTENANCE SCHEDULE
Once a Month
• Manually operate door. If it is unbalanced or binding, call
a trained door systems technician.
• Check to be sure door opens and closes fully. Adjust
limits and/or force if necessary. (See pages 23 and 24.)
• Repeat the safety reverse test. Make any necessary
adjustments. (See Adjustment Step 3.)
Once a Year
• Oil door rollers, bearings and hinges. The opener does
not require additional lubrication. Do not grease the door
tracks.
To Open the Door Manually
The door should be fully closed if
possible. Pull down on the
emergency release handle and
lift the door manually. To
reconnect the door to the opener,
press the door control push bar.
The lockout feature prevents the
trolley from reconnecting
automatically. Pull the emergency
release handle down and back
(toward the opener). The door
can then be raised and lowered
manually as often as necessary.
To disengage the lockout feature,
pull the handle straight down.
The trolley will reconnect on the
next UP or DOWN operation,
either manually or by using the
door control or remote.
To prevent possible SERIOUS INJURY or DEATH from a falling
garage door:
• If possible, use emergency release handle to disengage
trolley ONLY when garage door is CLOSED. Weak or broken
springs or unbalanced door could result in an open door
falling rapidly and/or unexpectedly.
• NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
• NEVER use handle to pull door open or closed. If rope knot
becomes untied, you could fall.
