ADJUSTMENTS

TO ADJUST SEALING DEPTH
Loosen nut (position 31), adjust hexagon socket set screw (position 44) with a hexagon key, turn counterclockwise to increase sealing depth, or turn clockwise to decrease sealing depth, retighten nut.

TO ADJUST CLEARANCE BETWEEN THE FEEDWHEEL (POSITION 5) AND GRIPPER (POSITION 26)
The clearance between the feedwheel and the gripper should be .020" (.51 mm). If the clearance is more or less than this, it must be adjusted.
To reduce the clearance: loosen nut (position 31A), turn hexagon socket set screw (position 30) counterclockwise with a ball hexagon key, re-tighten nut.
To increase the clearance: loosen nut (position 31A), turn hexagon socket set screw (position 30) clockwise with a ball hexagon key, re-tighten nut.
