DISASSEMBLY
5. Slide the barrel assembly from the
outer barrel shroud and muzzle
bushing.
6. Unscrew the firing chamber from the
barrel. NOTE: When ready to reassemble
the firing chamber, do not screw it
on tightly to the barrel so that it can
be readily aligned with the slot in the
receiver.
7. Remove the piston from the barrel by
pulling straight outward. If necessary
the piston can be removed by using a
rod inserted through the opening in the
rear of the barrel.
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 EYE PROTECTION 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 5-13/16”. When
less than this length, the piston must
be replaced to avoid tool damage.
10. Reassemble the tool in the reverse
order of disassembly.
ALWAYS PERFORM THE DAILY
FUNCTION TEST BEFORE USING THE
TOOL AFTER CLEANING OR SERVICING.
