2. Lubrication
(1) Prior to operating this nailer, be sure to provide an air
set between the air compressor and this device.
Lubrication through the air set offers smooth
operation, extended service life, and anticorrosion.
Adjust the oiler so that a single drop of oil is supplied
at intervals of 5 to 10 nailing cycles.
(2) It is recommended using the recommended oil (SHELL
TONNA). Other applicable oils are listed. Never mix
two or more types of different oils.
3. Load nails
CAUTION
When loading nails into Nailer,
(1) do not depress trigger;
(2) do not depress push lever; and
(3) keep your face, hands feet and other body parts,
as well as those of other persons away from the
nose muzzle to avoid possible injury during usage
and carrying.
(1) Pull the nail feeder until the concave portion of the
magazine cover clicks. (See Fig. 2)
(2) Insert nail strips one by one from above the magazine.
Slide nails forward in the magazine. (See Fig. 3)
(3) While holding the nail feeder adjust the magazine
cover in place. (See Fig. 4)
(4) Slide the nail feeder slowly forward until it contacts
nails.
NOTE
Slide the nail feeder SLOWLY forward.
If the nail feeder is released roughly, it may be stuck
between the magazine and nails, which makes mis-
feeding trouble.
Use nail strip of more than 5 nails.
Removing the nails:
1 Pull the nail feeder until the concave portion of the
magazine cover clicks. (See Fig. 2)
2 Remove the nails from the nailer.
CAUTION
To prevent unintentional operation, never touch the
trigger or place the top end of the push lever on a
work bench on floor. Also, never face the nail outlet
toward any part of a person.
HOW TO USE THE NAILER
CAUTION
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
This Hitachi 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. 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.

WARNING
A nail will fire 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.
(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).
The SINGLE SEQUENTIAL ACTUATION MECHANISM is
for use where precision fastener placement is desired.
The SINGLE SEQUENTIAL ACTUATION MECHANISM
may reduce the possibility of bodily injury to you or
others in the work area compared to the CONTACT
ACTUATION MECHANISM. This is because it is less
likely to drive an unwanted nail if you keep the trigger
pulled and accidentally bump the push lever against
yourself or others.
The SINGLE SEQUENTIAL ACTUATION MECHANISM
may also reduce the speed of operation compared to the
CONTACT ACTUATION MECHANISM. The SINGLE
SEQUENTIAL ACTUATION
recommended to inexperienced users.
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.
NOTE
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.
Always handle nails and package carefully. If nails
are dropped, collating bond may be broken.
After nailing:
(1) disconnect air hose from the nailer;
(2) remove all nails from the nailer;
(3) supply 5 – 10 drops of Hitachi pneumatic tool
lubricant into the air plug on the nailer; and
(4) open the petcock on the air compressor tank to
drain any moisture.
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.
