Cushion arm assembly consists of the door arm tube
section and door arm rod, which are packed
separately. To assemble, screw the door arm rod into
the door arm tube in a clockwise direction
approximately ten turns.
Connect cushion arm assembly into trolley with open
end of rod hook facing motor.

to 10” between the inside face of the door and the
solid cushion arm rod. If adjustment of the trolley
position is necessary, use the CLOSE TRAVEL AD-
JUSTMENT knob located on the bottom of the motor
power head unit. A 1/4 turn equals approximately 1”
of trolley movement; turn clockwise to move forward;
counterclockwise to move back.
