MAINTENANCE

Clean the sealing section regularly with compressed air to remove any dust and particles.
Lubricate the die (position 16) and punch (position 25) daily with a thin grade of oil.
This will reduce friction and extend the life of the tool as well as the parts.
Spray the entire tool daily with a rust preventative, this will prevent any rust formation.

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.

REPLACEMENT OF PARTS

Note: If you are not familiar with the following replacement procedures, please contact your authorized dealer for a demonstration or for service.

To Replace The Feedwheel (Position 5)

1.	Remove external retaining ring (position 3).
2.	Remove tensioning assembly (consisting of tension lever (position 11) and feedwheel shaft (position 2)).
3.	Install new feedwheel with the "O" and "l" marking facing the strap guide (position 4), reinstall tensioning assembly observing the key way position during assembly.
4.	Reposition strap guide onto the protruding feedwheel shaft.
5.	Reinstall external retaining ring.

To Replace The Gripper (Position 26)

Note: The gripper is held in a nonadjustable position with spring tension pin (position 27).

1.	To remove gripper, use drift pin matching the dimension of the spring tension pin (position 27) and drive the tension pin into the tool base, until the gripper comes loose from its position.
2.	Lift feedwheel lever (position 7) to access gripper.
3.	Clean cavity area and add one drop of a thin grade of oil in the cavity.
4.	To install new gripper, place the gripper into the cavity of the tool base. Reinstall the spring tension pin and drive it into the hole of the tool base, until it is flush with the tool base.
