Trolley and latch assembly must be at the
factory preset fully closed position, (see
illustration).
Verify preliminary trolley and latch assembly
close position is 11” to 13” between trolley
clevis pin and the inside face of the door.
If adjustment of the trolley/latch assembly
position is required, use the close travel
adjustment screw located on the bottom of
the opener. A 1/4 turn equals approximately
1” of trolley travel; turn clockwise to de-
crease distance between header and trolley
and counter-clockwise to increase distance
between header and trolley.
