6.2 Refer to 6.2. Remove enclosure wall and red
plug from enclosure adjustment access hole. If adjustment
is necessary, use adjustment knob to rotate feed
assembly to ensure one pair of set screws on feed collar
and polarization drive unit gear box align with adjustment
access hole. Note: Aligning one pair of set screws with
adjustment access hole will also align remaining set
screw pairs with cover plate opening and enclosure door
opening. Important: Adjustment of feed collar and gear
hub must not exceed 3/8 in. Feed assembly must not be
rotated such that either actuator screw passes between
limit switch rollers. Ensure all set screws are retightened
