Force Adjustment - Craftsman 200.57933 Owner's Manual

Force Adjustment

To prevent SERIOUS INJURY or DEATH from improper force adjustment:
- DO NOT adjust force to compensate for binding or sticking of the garage door. Call a qualified garage
door service technician to make necessary adjustments in case of binding.
- DO NOT increase the force beyond minimum force required for closing the door. Too much force will cause
improper operation of safety reversal mechanism.
- If either the force or travel limit adjustment is made, the other adjustment may also needed.
- After ANY adjustments, the safety reverse test MUST be performed to ensure the door reverses on
contact with a 1-1/2" thick object (2x4 laid flat) .
For safe operation, the force setting should
always be set at the MINIMUM FORCE
required to run the door.

WARNING
!
Adjusting Force
1. Force adjustment controls are located on the rear panel of
the opener. The force adjustments regulate the amount of
force required to open or close the door.
2. Force adjustment is applied only to compensate for the minor
resistance caused by weather or other conditions.
 Note: Force is preset at level 6 for both open and close
adjustments. The size and operating conditions of the
garage door will determine the correct level of force/
sensitivity. Weather conditions may also affect the operation
of the door requiring further adjustments as needed.
 Note: If the close force is set too light the opener will reverse
the door during closing. If the open force is set too light the
opener will stop the door during opening.
 Note: There are 12 levels for open and close force settings.
When either the maximum or minimum level is reached, the
light will flash 6 times.
 Never adjust the force setting by more than 1 level (1 press)
at a time.
Setting Force
Setting Close Force
1. If the door completes a full close cycle without reversing,
decrease (-) the close force by 1 level at a time until the door
reverses. If the door reverses during closing, increase (+)
close force by 1 level. The close force is now properly
adjusted.
2. During the "door-close" cycle, the opener will reverse if the
force required to close the door is exceeded.
Setting Open Force
1. If the door completes a full open cycle without stopping,
decrease (-) the amount of force by 1 level until the door
stops during the opening. Once the door stops during
opening, increase (+) open force by 1 level. The close force
is now properly adjusted.
2. During the "door-open" cycle the opener will stop if the force
required to open the door is exceeded.
