ADJUSTMENTS
TO ADJUST SEALING DEPTH
Loosen nut (position 33), adjust hexagon socket set screw (position 46) with a hexagon
key, turn counterclockwise to increase sealing depth, or turn clockwise to decrease sealing
depth, re-tigthen nut.
TO ADJUST CLEARANCE BETWEEN THE FEEDWHEEL (POSITION 5) AND GRIPPER
(POSTION 27)
The clearance between the feedwheel and the gripper should be .012" (.31 mm). If the
clearance is more or less than this, it must be adjusted.
To reduce the clearance: loosen nut (position 33A), turn hexagon socket set screw
(position 32) counterclockwise with a ball hexagon key, re-tighten nut.
To increase the clearance: loosen nut (position 33A), turn hexagon socket set screw
(position 32) clockwise with a ball hexagon key, re-tighten nut.
