HOW TO USE THE NAILER
CAUTIONS:
Never use the head or body of this nailer as a
hammer.
Take precautions to ensure the safety of persons in
the vicinity during operation.
1. Nailing procedures
(1) Method of intermittently driving nails (single shot)
The single-contact change lever is in the single shot
position (see Fig. 8).
This nailer includes a single shot structure to allow
driving of a single nail by pushing down the push lever
and pulling the trigger (see Fig. 7).
CAUTIONS:
[Method of intermittently driving nails (single shot)]
explained here is not [Sequential fire]. When Single-
contact Change Lever is at the Single shot position, if
the push lever is pushed up in a state where the trigger
is pulled, only one piece of nail in the shooting muzzle
is fired: Be careful!
In the event it is used by Sequential fire, use the
Sequential Fire Parts Set of Optical Accessory.
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.

When depressing the nail outlet, be sure to fully lift the
push lever (see Fig. 7) to release the safety lock. Thus,
nails cannot be driven without releasing the safety
lock even though the trigger is pulled.

CAUTION:
Exercise care when nailing corners of lumber. When
consecutive nailing is carried out at 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 some-
times does not operate correctly. Always operate the
machine at the appropriate ambient temperature.
2. Adjusting the nail-driving depth
CAUTION:
When making adjustments, be sure to remove your
finger from the trigger. When making adjustments, be
