PART ADJUSTMENT, REMOVAL & REPLACEMENT
REFER TO PAGES 7 AND 8 FOR ADDITIONAL INFORMATION
DISASSEMBLY OF TOOL:
1. Remove the seals from the magazine and the sealer mechanism.
2. To remove both units loosen the cutter adjustment screw (33) and remove the top and
bottom cap screws in the sealer frame (1 and 2).
3. Push the magazine out to the side so the locating lug clears the offset in the frame. Pull
back the entire sealer mechanism and magazine assemblies, twisting the front outward away
from the sealer frame. Remove both assemblies from the sealer frame.
4. The magazine is now easily separated from the sealer mechanism. The magazine and sealer
mechanisms are now accessible for examination and replacement of worn or broken parts.
The sealer mechanism is serviced by removing the cutter blade pins and cutter blade. Clean
the parts. Jaws and notchers are replaced as required. Note that the outer jaws can be
reversed front to back to provide new cutting edges, doubling the life of these parts. After
necessary repairs have been made, grease the parts or apply light machine oil. The tool is
now ready for reassembly.
REASSEMBLY OF TOOL:
1. Place the sealer mechanism against the magazine and hold the units together.
2. Be sure the strap latch spring (26) is in the correct position in the tensioner frame (23).
3. Insert the lower portion of the assembly into the tool first and hook the slot in the sealer cam
(70) on to the cam roller (7) inside of the sealer frame. Then swing the front of the sealer
mechanism into the sealer frame so that the guide on the jaw support (76) aligns with the
groove in the front of the sealer frame. Then push the whole assembly forward into place
engaging the lug in the side of the magazine into the offset in the sealer frame.
4. Insert and snug up but do not tighten the top and bottom cap screws (1 and 2).
5. With jaws in the down position, advance the cutter adjustment set screw (33) until a slight
bind can be felt when operating the sealer handle.
6. Securely tighten the top and bottom cap screws (1 and 2).
7. Insert a stack of seals into the magazine. Operate the sealer mechanism through 3 or 4
cycles to check tightness of the cutter adjustment set screw and see that the seals feed
properly. If the sealer mechanism is excessively tight, back off the cutter adjustment set
screw slightly. Next, apply a strap under tension to be sure that all elements of the tool
operate properly.
EJECTOR (48) AND EJECTOR LEVER (46) W/O MAGAZINE REMOVAL:
1. Remove the seals from the magazine.
2. Remove the Truarc (43) from the right side of the ejector arm pin (42).
3. Lift the sealer handle to clear the ejector arm pin (42).
4. Drive out the ejector arm pin (42) from the sealer handle side.
5. Remove the ejector arm spring (45).
6. Place the sealer mechanism in the UP position with the sealer handle in the rest position.
7. Hold the gripper lever (35) down and pull out the ejector lever.
EJECTOR DISASSEMBLY
1. Drive out the roll pin (49) from the ejector pin (50). Be sure to support the ejector lever (46).
See Figure 7.
2. Remove the pin (50), ejector (48), and spring (47). Replace the ejector lever and/or ejector as
necessary.
3. Reassemble with the new ejector by following these steps in reverse order.
NOTE: If only the ejector needs to be replaced, it can be removed without removing the ejector
lever following the above 3 steps.
