(1) Intermittent nailing
Set the switching device to the upward position (to
set to SINGLE ACTUATION MECHANISM) (See Fig.
5).
Depress the nail outlet onto the desired point; then
pull the trigger to drive a nail in a single shot (See
Fig. 6).
After nailing once, nailing will not be possible again
until the trigger is released and pressed again.

CAUTION
If you do not pull the trigger quickly and crisply
while in the single shot mode, the nailer will bounce
and shoot several nails instead of just one. To avoid
this, be sure to pull the trigger quickly and crisply.
(2) Push lever
When depressing the nail outlet, be sure to fully
lift the push lever (See Fig. 6) to release the safety
lock. Thus, nails cannot be driven without releasing
the safety lock even though the trigger is pulled.
(3) Continuous nailing
Set the switching device to the downward position (to
set to CONTACT ACTUATION MECHANISM) (See Fig.
7).
First, pull the trigger. Then depress the devise onto
the desired position to automatically drive nails (See
Fig. 8).

CAUTION
Excercise care when nailing corners of lumber.
When continuous nailing corners of lumber, a nail
may go astray or break through the corner.
Do not drive a nail on another nail.
Do not drive a nail on metal parts.
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 damper, 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 5–
10 drops 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 nailing depth (See Fig. 9)
To assure that each nail penetrates to the same
depth, be sure that:
(1) the air pressure to the Nailer remains constant
(regulator is installed and working properly),
and
(2) the Nailer is always held firmly against the
workpiece.
If nails are driven too deep or shallow into the
workpiece, adjust the nailing in the following order.
1 DISCONNECT AIR HOSE FROM NAILER.
2 If nails are driven too deep, turn the adjuster
to the shallow side.
Adjustment are in half-turn increments.
If nails are driven too shallow, turn the adjuster to
the deep side.
3 Stop turning the adjuster when a suitable position
is reached for a nailing test.
4 Connect the air hose.
ALWAYS WEAR EYE PROTECTOR.
Perform a nailing test.
5 DISCONNECT AIR HOSE FROM NAILER.
6 Choose a suitable position for the adjuster.
