IMPORTANT INFORMATION
Read and understand tool labels and all of the operating
instructions, safety precautions and warnings in this manual before
operating or maintaining this nailer.
Failure to follow warnings could result in DEATH or SERIOUS
INJURY.
Most accidents that result from the operation and maintenance of Nailers are caused by the
failure to observe basic safety rules or precautions. An accident can often be avoided by
recognizing a potentially hazardous situation before it occurs, and by observing appropriate
safety procedures.
Basic safety precautions are outlined in the “SAFETY” section of this Manual and in the
sections which contain the operation and maintenance instructions.
Hazards that must be avoided to prevent bodily injury or machine damage are identified by
DANGERS and WARNINGS on the Nailer and in this Manual.
Never use this Nailer for applications other than those specified in this Manual.
DEFINITIONS OF SIGNAL WORDS
DANGERindicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
WARNINGindicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTIONindicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury, or may cause machine damage.
NOTE   emphasizes essential information.

SAFETY
IMPORTANT SAFETY INSTRUCTIONS
FOR USING NAILERS
READ ALL INSTRUCTIONS
DANGER
1. OPERATORS AND OTHERS IN WORK AREA MUST WEAR SAFETY GLASSES WITH SIDE
SHIELDS.
When operating the Nailer, always wear safety glasses with side
shields, and make sure others in work area wear safety glasses, too.
Safety glasses must conform to the requirements of American
National Standards Institute, ANSI Z87.1 and provide protection
against flying particles both from the front and side.
The employer must enforce the use of safety glasses by the Nailer
operator and others in work area.
2. NEVER USE OXYGEN OR OTHER BOTTLED GASSES. EXPLOSION MAY OCCUR.
Never use oxygen, combustible gases or any other bottled gases as
a power source for the Nailer.
Use of the above gases is dangerous, as the Nailer will explode.
Use only clean, dry, regulated compressed air.
WARNING
3. NEVER POINT TOOL AT YOURSELF OR OTHERS IN WORK AREA.
Always assume the Nailer contains fasteners.
Never point the Nailer at yourself toward yourself or others, whether
it contains fasteners or not.
If fasteners are mistakenly driven, it can lead to severe injuries.
Never engage in horseplay with the Nailer.
Respect the Nailer as a working implement.
4. KEEP FINGERS AWAY FROM TRIGGER WHEN NOT DRIVING FASTENERS TO AVOID
ACCIDENTAL FIRING.
Never carry the Nailer with finger on trigger since you could drive a fastener
unintentionally and injure yourself or someone else.
Always carry the Nailer by the handle only.
5. CHOICE OF TRIGGERING METHOD IS IMPORTANT.
Read and understand section titled “METHODS OF OPERATION”. (pages 16 – 18)
6. DO NOT EXCEED 120 psi. (8.3 bar 8.5 kgf/cm
2)
Do not exceed maximum recommended air pressure
120 psi (8.3 bar 8.5 kgf/cm
2).
Never connect the Nailer to pressure which potentially
exceeds 200 psi (13.7 bar  14 kgf/cm
2) as the Nailer can
burst.

SAFETY — Continued
WARNING
the push lever is operating properly,
otherwise the Nailer could drive a fastener
unexpectedly. Do not tamper with or
remove the push lever, otherwise the
push lever becomes inoperable.
15.KEEP ALL SCREWS AND COVERS
TIGHTLY IN PLACE.
Keep all screws and covers tightly
mounted. Check their condition
periodically.
Never use the Nailer if parts are missing
or damaged.
16.DO NOT LOAD FASTENERS WITH
TRIGGER OR PUSH LEVER DEPRESSED.
When loading fasteners into the Nailer or
when connecting the air hose,
1) do not pull the trigger;
2) do not depress the push lever; and
3) keep the Nailer pointed downward.
17. KEEP HANDS AND FEET AWAY FROM
FIRING HEAD DURING USE.
Never place your hands or feet closer
than 8 inches (200 mm) from the firing
head.
A serious injury can result if the fasteners
are deflected by the workpiece, or are
driven away from the point of entry.
18.PLACE NAILER PROPERLY ON
WORKPIECE.
Do not drive fasteners on top of other
fasteners or with the Nailer at too steep of
an angle; the fasteners can ricochet and
hurt someone.
19. BEFORE STARTING WORK, CHECK THE
NAILING OPERATION SWITCHING
DEVICE.
This Hitachi nailer includes a nailing
operation switching device.
Before starting work, check the setting of
the operation switching device.
If the switching device is not set properly,
the nailer will not operate correctly.
20. BE CAREFUL OF DOUBLE FIRE DUE TO
RECOIL.
If the push lever is unintentionally allowed
to re-contact the workpiece following
recoil, an unwanted fastener will be
driven.
In order to avoid this undesirable double
fire, 7.ALWAYS WEAR EAR AND HEAD
PROTECTION.
Always wear ear protection to protect
your ears from loud noise.
Always wear head protection to protect
your head from flying objects.
8. STORE NAILER PROPERLY.
When not in use, the Nailer should be
stored in a dry place. Keep out of reach of
children. Lock the storage area.
9. KEEP WORK AREA CLEAN.
Cluttered areas invite injuries. Clear all work
areas of unnecessary tools, debris, furniture,
etc.
10.NEVER USE IN PRESENCE OF
FLAMMABLE LIQUIDS OR GASES.
The Nailer produces sparks during
operation.
Never use the Nailer in sites containing
lacquer, paint, benzine, thinner, gasoline,
gases, adhesive agents, and other
materials which are combustible or
explosive.
11. KEEP VISITORS AWAY.
Do not let visitors handle the Nailer.
All visitors should be kept safely away
from work area.
12. DRESS PROPERLY.
Do not wear loose clothing or jewelry as
they can be caught in moving parts.
Rubber gloves and nonskid footwear are
recommended when working outdoors.
Wear protective hair covering to contain
long hair.
13. NEVER USE NON RELIEVING COUPLER
ON NAILER.
If a non relieving coupler is used on the
Nailer, the Nailer can remain charged
with air after disconnecting and thus will
be able to drive a fastener even after
disconnecting.
The Nailer and air hose must have a hose
coupling such that all pressure is removed
from the Nailer when the coupling joint is
disconnected.
14. CHECK PUSH LEVER BEFORE USE.
Make sure the push lever operates
properly. (The push lever may be called
“Safety”.) Never use the Nailer unless

SAFETY — Continued
WARNING

Intermittent operation (Trigger firing)
1) Set the switching device to SINGLE
SEQUENTIAL ACTUATION
MECHANISM.
2) Pull the trigger rapidly and firmly.

Continuous operation (Push lever firing)
1) Do not press the nailer against the
wood with excessive force.
2) Separate the nailer from the wood as
it recoils after nailing.
21. DO NOT DRIVE FASTENERS INTO THIN
BOARDS OR NEAR CORNERS AND
EDGES OF WORKPIECE.
The fasteners can be driven through or
away from the workpiece and hit
someone.
22. NEVER DRIVE FASTENERS FROM BOTH
SIDES OF A WALL AT THE SAME TIME.
The fasteners can be driven into and
through the wall and hit a person on the
opposite side.
23. CHECK FOR LIVE WIRES.
Avoid the risk of severe electrical shock
by checking for live electrical wires that
may be hidden by walls, floors or ceilings.
Turn off the breaker switch to ensure
there are no live wires.
24. NEVER CARRY NAILER BY HOSE.
25. DO NOT OVERREACH.
Keep proper footing and balance at all
times.
26.NEVER USE NAILER WHICH IS
DEFECTIVE OR OPERATING
ABNORMALLY.
If the Nailer appears to be operating
unusually, making strange noises, or
otherwise appears defective, stop using
it immediately and arrange for repairs by
a Hitachi authorized service center.
27. DO NOT DISCONNECT AIR HOSE FROM
NAILER WITH FINGER ON TRIGGER.
The Nailer can fire when re-connected to
an air supply.
28. DISCONNECT AIR HOSE FROM NAILER
WHEN:
1) doing maintenance and inspection;
2) clearing a jam;
3) it is not in use;
4) leaving work area;
5) moving it to another location; and6) handing it to another person.
Never attempt to clear a jam or repair the
Nailer unless you have disconnected air
hose from the Nailer and removed all
remaining fasteners from the Nailer.
The Nailer should never be left unattended

children, individuals unfamiliar with its
operation or unauthorized personnel.
31.
NEVER USE NAILER FOR APPLICATIONS
OTHER THAN THOSE SPECIFIED IN THIS
MANUAL.
32. HANDLE NAILER CAREFULLY.
Because of high air pressure in the Nailer,
cracks in the surface are dangerous.
To avoid this, do not drop the Nailer or
strike the Nailer against hard surfaces;
and do not scratch or engrave signs on
the Nailer. Handle the Nailer carefully.
33. MAINTAIN NAILER WITH CARE.
Keep the Nailer clean and lubricated for
better and safer performance.
