HOW TO USE THE NAILER
CAUTIONS:
Never use the head or body of this device 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
striking of a single nail by pushing down the push
lever and pulling the trigger (see Fig. 7).
CAUTION:
[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.

single-contact change lever to the contact driving
position.
First pull back the trigger. Then press the nail outlet

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. How to use nosecap
CAUTION:
Remove the hose from the nailer and release the
compressed air before installing or removing the
nosecap to prevent accidental nail ejection.
Attach the nose cap (A) on the tip of the push lever
when you wish to protect the surface of wood, etc.,
from scratches.
