CAUTION:
• Always disconnect the air hose from the tool before
attempting to perform inspection or maintenance.
Cleaning and removal of tar and dirt
Adhesion of tar and dirt to areas around the contact element
will prevent smooth movement of the contact element (safety
mechanism), causing accidental discharge. Periodically
clean the areas around the contact element. Cleaning can be
performed easily if the contact element is removed. So pro-
ceed as follows.
Turn the adjuster so that the arrow will point between num-
005635
bers 1 and 5.
Hold the contact element and press the knob toward the
nose tip. While keeping the knob pressed, turn it counter-
clockwise fully. Then release the knob and remove the con-
tact element from the driver guide. If you have difficulty
3 removing the contact element because it is caught by the
safety cover, open the magazine cap.
Use a solvent such as kerosene, #2 fuel oil or diesel fuel.
005636
Immerse only the contact element and the areas around the
ejection port in solvent and remove tar and dirt with brush.
Always wear waterproof gloves to protect your hands. Never
immerse the housing, magazine, etc. in solvent. Malfunction
of the tool may result. Always dispose of the solvent used in
a safe and prudent manner and in compliance with all local
2
and national code requirement.
Dry off the tool before use. Any oil film left after cleanup will
accelerate the tar buildup, and the tool will require more fre-
quent recleaning. After drying off the tool, oil the moving
parts to prevent rusting and to assure good lubrication and
