Care of Your Opener
LIMIT AND FORCE ADJUSTMENTS:
Weather conditions may cause some
minor changes in door operation
requiring some readjustments,
particularly during the fi rst year of
operation.
Pages 21 and 22 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 23) after any adjustment of limits or force.
MAINTENANCE SCHEDULE
Every 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 21 and 22.)
• Repeat the safety reverse test. Make any necessary
adjustments. (See Adjustment Step 3.)
Two Times a Year
• Check chain tension. Disconnect trolley fi rst. Adjust if
necessary. (See page 7.)
Every Year
• Oil door rollers, bearings and hinges. The opener does
not require additional lubrication. Do not grease the
door tracks.
Every Three to Four Years
• Use a rag to wipe away the existing grease from the
garage door opener rail. Reapply a small layer of white
lithium grease to the rail.
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 button.
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.
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.
