CAUTION:
Exercise care when nailing corners of lumber. When
continuous nailing corners of lumber, a nail may go
astray or break through the corner.
NOTES:
Precautions on no-load operation
Sometimes nailing will continue after driving in all
nails previously contained in the magazine.
This is termed "no-load operation". Such operation
may deteriorate the bumper, magazine, and nail feeder.
To avoid no-load operation, occasionally confirm the
amount of remaining nails. On the other hand, all nails
should be removed after using this nailer.
After completing operation, put into the body about
2cc oil through the hose joint to protect the tool from
rust.
Under low temperature conditions, the machine
sometimes does not operate correctly. Always operate
the machine at the appropriate ambient temperature.
2. Adjusting the nail-driving depth
CAUTIONS:
When making adjustments, be sure remove your
finger from the trigger. When making adjustments, be
sure that the nail outlet is not facing downward and
that body parts or other persons are not in the path of
the nail outlet.
Adjusting the adjuster (Fig. 11)
Carry out test driving. If the nails are too deep, turn
the adjuster to the shallow side (
If the nail depth is too shallow, turn the adjuster
to the deep side (
Depth is changed 1 mm with each rotation of the
adjuster.

NOTES:
When adjusting the adjuster, it does not rotate more
than 3 mm from the deepest point where a nail goes
down. Do not rotate the adjuster by force beyond that
point.
The nail-driving depth can also be adjusted by changing
the air pressure used. Carry this out together with
movement of the adjuster. Using a high air pressure
that does not match the nail-driving resistance will
shorten the life of this nailer.
3. Changing the exhaust direction.
The direction of the exhaust vent can be changed
within 360° by turning the top cover. (Fig. 13).

INSPECTION AND MAINTENANCE

CAUTION:
Be sure to disconnect the hose during cleaning
jams, inspection, maintenance and cleaning.
1. Countermeasure for nail jamming
(1) Remove the nail roll from the magazine, open the nail
guide, insert a rod into the nail outlet and tap the rod
with a hammer. (Fig. 14).
(2) Remove the jammed nail with slotted-head screw-
driver. (Fig. 15)
