DISASSEMBLY
6. Unscrew the breech plug from the
rear of the barrel using a 1” wrench.
Protect the barrel from damage if a
vise is used to hold the barrel during
the disassembly.
7. Slide the piston out of the barrel
assembly. If necessary, tap the breech
plug end of the barrel on a wood block
to free the piston.
8. Inspect all parts for wear or damage
and clean or replace as required.
Use detergent oil and cleaning brush.
Wipe parts dry before reassembly.
WEAR SAFETY GOGGLES WHEN
CLEANING TOOL PARTS.
9. Check the piston tip for mushrooming
or other deformities, and grind flat.
The tip of the piston must be 90° to
the shank and grinding must only
be done by qualified personnel. The
overall minimum length of the piston
must not be less than 6-1/16”. When
less than this length, the piston must
be replaced to avoid tool damage.
10. Inspect all tool parts for wear or damage
and clean or replace as required. Wipe
all parts dry before reassembly.
11. Reassemble the tool in the reverse order
of disassembly. Align the stop grove in
the barrel with the stop opening in the
tool housing when replacing the barrel.
ALWAYS PERFORM THE DAILY
FUNCTION TEST BEFORE USING THE
TOOL AFTER CLEANING OR SERVICING.
