MAINTENANCE
CAUTION :
Always be sure that the air hose is disconnected from the tool before attempting to perform
inspection or maintenance.
Cleaning and removal o f 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 i s
removed. So proceed as follows.
Turn the adjuster so that the arrow will point between
numbers 1 and 5.
Hold the contact element and press the knob toward
the nose tip. While keeping the knob pressed, turn it
counterclockwise fully. Then release the knob and re-
move the contact element from the driver guide. If you
have difficulty 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. 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 pro-
tect 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 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 frequent recleaning. After drying off the tool, oil the moving parts to
prevent rusting and to assure good lubrication and operation or moving parts. Install the contact
element
on
the driver guide. Press the knob toward the nose tip and turn the knob clockwise to
secure.
WARNING:
Never use gasoline or other similar highly volatile liquids for cleaning. Vapors of such liquids
may enter the tool and could be ignited by sparks produced during nailing and cause an explo-
sion.
