Maintenance
IMPORTANT:
Clean tool after each days use. Disassemble and clean the barrel assembly with
the wire brush provided with tool.
Notice: DO NOT attempt to clean power load
strip channel with wire brush. Apply good quality penetrating lubricant spray (such
as WD-40) sparingly and wipe dry.
PISTON OVERDRIVE
If the tool does not open after firing and the piston is 1/2 inch or more out of the
muzzle:
1. Strike muzzle end of tool against hard surface to force piston back into muzzle.
2. Advance power load strip and reset piston (See step 6 of Operation).
