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.

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.

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