DISASSEMBLY
6. Slide the piston out of the rear barrel
assembly and slide the guide out of the
front barrel.
The tool is now disassembled for normal
cleaning. Inspect all parts for wear or
damage and clean or replace as required.
Use detergent oil and cleaning brushes to
remove dirt and powder residues. Wipe all
parts dry before reassembly. Wear safety
goggles when cleaning tool parts.
7. Check the piston tip for damage and
grind flat. The tip of the piston must be
90° to the shank. Grinding should only
be done by qualified personnel. The
minimum overall length of the piston
must not be less than 5-5/8" long. When
less than 5-5/8" long, the piston must
be replaced to avoid tool damage.
8. Reassemble the tool in the reverse
order of disassembly. When sliding the
front barrel onto the rear barrel, align
the groove in the rear barrel with the
groove in the front barrel.
9. Align the groove in the rear barrel with
the pawl opening in the tool body when
placing the barrel assembly into the tool
body. Replace the pawl and install the
barrel retention clip.
ALWAYS PERFORM THE DAILY FUNCTION
TEST BEFORE USING THE TOOL AFTER
