– 0.83 MPa (4.9 – 8.3 bar).
Adjust the air pressure between 0.49 to 0.83 MPa
(4.9 – 8.3 bar) according to the diameters and length
of nails and hardness of the wood being nailed. Pay
special attention to the output pressure, capacity, and
piping on the air compressor, so that air pressure does
not exceed the speci

ed limit. Note that excessive
pressure may a
ff
ect overall performance, service life,
and safety.

1. Nailing procedures
This HiKOKI nailer is equipped with a nailer operation
switching device.
Use SINGLE SEQUENTIAL ACTUATION MECHANISM
or CONTACT ACTUATION MECHANISM in accordance
with the work to be performed.
(1) Intermittent nailing
Set the switching device to the upward position (to set
to SINGLE SEQUENTIAL ACTUATION MECHANISM)
(See
Fig. 3
).
Depress the nail outlet onto the desired point; then pull
the trigger to drive a nail in a single shot (See
Fig. 4
).
After nailing once, nailing will not be possible again until
the trigger is released and pressed again.
WARNING
A nail will
fi
re each time the trigger is depressed as long
as the push lever remains depressed.
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.
