NOTE: Door STOPS In UP direction if anything
interferes with door travel. Door REVERSES in
DOWN direction if anything interferes with door
travel (including binding or unbalanced doors).
If force adjustments are set too light, door travel may
be interrupted by nuisance reversals in the DOWN
direction and stops in the UP direction As weather
conditions can affect door movement, occasional
adjustment may be needed
The 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
