IMPORTANT INFORMATION
READ AND UNDERSTAND ALL OF THE OPERATING INSTRUCTIONS, SAFETY PRECAUTIONS AND WARNINGS IN
THIS MANUAL BEFORE OPERATING OR MAINTAINING THIS NAILER.
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

IMPORTANT SAFETY INSTRUCTIONS FOR USING NAILERS
READ AND UNDERSTAND ALL INSTRUCTIONS
1. ALWAYS WEAR EYE PROTECTOR.
2. NEVER USE BOTTLED GASES.
SAFETY
DANGER
When operating the Nailer, always wear eye protector with side
shields, and make sure others in work area wear eye protector, too.
Eye protector 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 eye protector by the Nailer
operator and others in work area.
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. DO NOT EXCEED 120 psi.
Do not exceed maximum recommended air pressure120 psi (8.3 bar
8.5 kgf/cm
Never connect the Nailer to pressure which potentially exceeds 200
psi (13.7 bar 14 kgf/cm2) as the Nailer can burst.
4. NEVER POINT NAILER TOWARD YOURSELF OR ANYONE ELSE.
Always assume the Nailer contains fasteners.
Never point the Nailer toward yourself or anyone else, 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.
5. NEVER CARRY WITH FINGER ON TRIGGER.
Remove finger from trigger when not driving fasteners.
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.
6. ALWAYS WEAR EAR AND HEAD PROTECTOR.
Always wear ear protector to protect your ears from loud noise.
Always wear head protector to protect your head from flying objects.
7. 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.
8. KEEP WORK AREA CLEAN.
Cluttered areas invite injuries. Clear all work areas of unnecessary tools, debris, furniture, etc.
9. 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.
10. KEEP VISITORS AWAY.
Do not let visitors handle the Nailer.
All visitors should be kept safely away from work area.

WARNING
11. 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.
12. 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.
13. CHECK PUSH LEVER BEFORE USE.
Make sure the push lever operates properly. (The push lever may be called ìSafetyî.) Never use the Nailerunless
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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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,
1) do not push the Nailer on the workpiece with strong force;
2) take the Nailer completely away from the workpiece using recoil, and keep the push lever away from the
workpiece until the next desirable shot; and
3) pull the trigger and release it QUICKLY when performing intermittent operation (trigger fire).
19. 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.
20. 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.
21. 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.
22. NEVER CARRY NAILER BY HOSE.
23. DO NOT OVERREACH.
Keep proper footing and balance at all times.
24. 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.
25. DO NOT DISCONNECT AIR HOSE FROM NAILER WITH FINGER ON TRIGGER.
The Nailer can fire when re-connected to an air supply.

WARNING
26. TURN LOCK LEVER TO LOCK POSITION AND 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;
6) handing it to another person; and
7) using hook.
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 since people who are not familiar with the Nailer might handle it and
injure the themselves.
27. STAY ALERT.
Watch what you are doing. Use common sense.
Do not operate the Nailer when you are tired.
The Nailer should never be used by you if you are under the influence of alcohol, drugs or medication that
makes you drowsy.
28. HANDLE NAILER CORRECTLY.
Operate the Nailer according to this Manual.
Never allow the Nailer to be operated by children, individuals unfamiliar with its operation or unauthorized
personnel.
29. NEVER USE NAILER FOR APPLICATIONS OTHER THAN THOSE SPECIFIED IN THIS MANUAL.
30. 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.
31. MAINTAIN NAILER WITH CARE.
Keep the Nailer clean and lubricated for better and safer performance.
32. USE ONLY PARTS, ACCESSORIES OR FASTENERS SUPPLIED OR RECOMMENDED BY HITACHI.
Unauthorized parts, accessories, or fasteners may void your warranty and can lead to malfunction and resulting
injuries.

Never modify or alter a nailer. Doing so may cause it to malfunction and personal injuries may result.
33. DO NOT REMOVE DUST COVER
Fragments of wire collating fasteners can fly out.
34. CLOSE NAIL GUIDE AND DO NOT OPEN IT DURING OPERATION
If driving fasteners with the nail guide open, the fastners can be driven from the workpiece.
