diffuser against the cable liner using 5/64" (2.0mm)

GUN HANDLE DISASSEMBLY

The internal parts of the gun handle may be inspected
or serviced if necessary.
The gun handle consists of two halves that are held
together with a collar on each end.
To open up the handle:
1. Turn the collars approximately 60 degrees coun-
terclockwise (the same direction as removing a
right hand thread) until the collar reaches a stop.
2. Pull the collar off the gun handle.
NOTE: If the collars are difficult to turn, position the
gun handle against a corner, place a screwdriver
against the tab on the collar and give the screwdriver a
sharp blow to turn the collar past an internal locking rib.
See Figure D.3.
