Changing Chisels on a Machine
To change the chisels, turn off power and air to the machine.
1.
Perform Lockout/Tagout
2.
With the air off, the chisel cylinders can be pulled out of their retracted position to
work on the chisel(s).
3.
Remove covers to access the chisels
Important: Be alert that all tools in the assembly are sharp and can cause injury.
4.
Using a 7/16” wrench, loosen and remove the bolts retaining the chisel clamps.
Remove the clamp and chisel.
5.
Clean off any particulate that may have accumulated on the clamp and chisel area.
This is especially important for the lower tools, where particulate can get trapped on
the tool surface instead of falling under gravity’s influence.
6.
Place the new chisel in the fixture, add the clamp, and tighten down the bolts back
onto the clamp.
7.
Verify that the chisel does not wobble in the fixture after tightening. Chisels should
be rigid and straight in the assembly.
8.
Push the chisel cylinder back into the machine head.
Clear the machine area and turn back on air and power to the machine.
