a. Turn the nail holder about 90 degrees
counterclockwise.
b. Slide in vertical direction possible.
Lift or lower the nail holder to accept different
length nails.
c. Adjust the plate to the nail length reference points
on the magazine cover and turn the nail holder 90
degrees clockwise until you hear "click".
(3) Place the nail coil into the magazine.
Uncoil enough nails to reach the driving hole (Fig. 5).
When using wire collated nails
Insert the first nail into the driving hole and the
second nail between the two pawls of the feeder.
Fit the nail head in the guide slot (Fig. 6).
(4) Close the magazine cover first and swing the nail
guide closed (Fig. 7).
(5) Lock the knob correctly.
NOTE
Be careful not to deform the collated wires and not to
disengage the nails with the guide surface.
Otherwise, the nail guide will not close correctly.
CAUTION
To prevent unintentional operation, never touch the
trigger or place the top end of the push lever on a
work bench or floor. Also, never face the nail outlet
toward any part of a person.
NOTE
Before loading the nails in the magazine, position the
nail holder according to the length of the nail. If the
nail holder position is not adjusted properly, nail
feed may jam. If the cover is forcibly closed without
adjusting the position of the nail holder, the nail
holder may be damaged.
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
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
MECHANISM) (See Fig. 8).
Depress the nail outlet onto the desired point; then
pull the trigger to drive a nail in a single shot (See
Fig. 9).
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.

SEQUENTIAL
ACTUATION
(2) Push lever
When depressing the nail outlet, be sure to fully lift
the push lever (See Fig. 9) 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. 10).
First, pull the trigger. Then depress the devise onto
the desired position to automatically drive nails (See
Fig. 11).
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
Exercise 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.
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.
Under low temperature conditions, the machine
sometimes does not operate correctly. Always operate
the machine at the appropriate ambient temperature.
2. Adjusting the nail-driving depth
CAUTIONS
When making adjustments, be sure remove your
finger from the trigger. When making adjustments,
be sure that the nail outlet is not facing downward
and that body parts or other persons are not in the
path of the nail outlet.
