MAINTENANCE
CAUTION:
Always disconnect the air hose from the tool before
•
attempting to perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
Cleaning and removal of tat and dirt
Adhesion of tar and dirt to areas around the contact
element will prevent smooth movement of the contact
element (safety mechanism),
discharge. Periodically clean the areas around the
contact element. Cleaning can be performed easily if the
contact element is 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
remove 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.

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 explosion.

performed. Test for possible faulty operation with nails
unloaded.
