TOOL ADJUSTMENTS, Continued
STRAP CUTTER
The VT strap cutter has two serrated cutting edges.
After the first edge has become dull or strap cut-off
becomes difficult the blade can be remounted to use
the second cutting edge. Once both edges have
become worn the blade should be replaced. Use the
instructions below to remount, install and adjust a
new cutter blade.
1. Remove the two mounting screws which secure
the air motor to the tool body. Remove the weld
motor from the tool by turning the motor counter-
clockwise to release the O-ring which seats on
the top of the motor.
NOTE: The small spring contained in the holder does not need to be removed to change
the cutter blade.
2. The cutter blade group of parts can now be removed from the tool. Continue to also remove
the cutter pin from the tool.
3. Remove the two smaller screws which mount the cutter blade to the holder. Rotate the cutter
blade to the new cutting edge and reinstall the mounting screws.
NOTE: If both cutting edges are worn replace the cutter blade at this point.
4. Reinstall the cutter group of parts back into the tool. Before installing the cutter pin inspect
the cutter holder movement within the tool.
A. The holder should move freely up and
down in the tool body. If the holder does
not move freely inspect the tool for debris
or damage.
NOTE: If the holder has been replaced
it may also be necessary to adjust the
clearance of the two cutter guides.
B. The holder should not be able to move
from side to side. Excessive side to side
clearance will result in poor strap cut-off. If
the holder does move side to side, loosen
the four mounting screws which secure
the side guides. Move the guides as
needed to obtain a 0.025mm to 0.127mm
(0.001"-0.005") clearance.
C. Tighten the mounting screws.
5. Once the cutter holder has been inspected and adjusted, continue to reinstall the remaining
parts in the order that they were removed.
6. Run a few test cycles on the tool to confirm that the strap cut-off performs properly.
