ADJUSTMENT STEP 2
Adjust Force
Force Adjustment Controls are located on rear panel
of opener. FORCE ADJUSTMENT settings regulate
amount of the power required to open and close
door.
NOTE: The door STOPS in the UP direction if
anything interferes with its travel. Door
REVERSED in the DOWN direction if anything
interferes with its travel (including binding or
unbalanced doors).
If the force adjustments are set too light, door travel
may be interrupted by nuisances reversals in DOWN
direction and stops in UP direction. Weather
conditions can affect the door movement, so
occasional adjustment may be needed.
Maximum force adjustment range is 260 degrees,
about 3/4 of a complete turn. Do not force controls
beyond that point. Turn force adjustment controls with
a screwdriver.
