FORCE WILL INTERFERE WITH THE PROPER
OPERATION OF THE SAFETY REVERSE SYSTEM OR
DAMAGE THE GARAGE DOOR.
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 REVERSES
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 nuisance 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.
