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 GASES. 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 NAILS 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.

English

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 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. 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).

20. 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.

21. 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.

22. 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.

Air compressor size formula

Amount of air required

=number of Nailers

× average nails driven each minute per Nailer

× air consumption at given air pressure

× safety factor (always 1.2)

Example: 2 Nailers operating at 100 psi driving 30 nails

per minute

Amount of air required

=2 × 30 × .046 (1.3) × 1.2

/min) (94 ltr/min)

After making the calculations as shown above, you

should find a compressor providing 3.3 CFM of air that

is required.

LUBRICATION

It is important that the Nailer be properly lubricated.

Without proper lubrication, the Nailer will not work

properly and parts will wear prematurely.

䡬 Use Hitachi pneumatic tool lubricant.

Do not use detergent oil or additives. These lubricants

will harm the O-rings and other rubber parts. This will

cause the Nailer to malfunction.

䡬 Filter-regulator-lubricator units should always be

used.

Keep the lubricator filled with Hitachi pneumatic tool

lubricant.

䡬 If a lubricator is not available, supply 5 – 10 drops of

Hitachi pneumatic tool lubricant into the air plug on

the Nailer twice a day.

COLD WEATHER CARE

䡬 Do not store the Nailer in a cold weather environment.

Keep the Nailer in a warm area until beginning the

work.

䡬 If the Nailer is already cold, bring it in a warm area

and allow the Nailer to warm up before use.

1 Reduce the air pressure to 64 psi (4.4 bar

4.5 kgf/cm

2 Remove all nails from the Nailer.

3 Connect the air hose and free-fire (blank-fire) the

Nailer.

The lowered air pressure will be enough to free-

fire the Nailer.

Slow speed operation tends to warm up the

moving part.

CAUTION

䢇 Do not free-fire the Nailer at high pressure.

TESTING THE NAILER

DANGER

䢇 Operators and others in

work area MUST wear

safety glasses with side

shields which conforms

䡺 THE NAILER MUST OPERATE PROPERLY.

ADJUSTING AIR PRESSURE

WARNING

䢇 Do not exceed 120 psi (8.3 bar 8.5 kgf/cm

Adjust the air pressure at recommended operating

pressure 70 – 120 psi (4.9 – 8.3 bar 5 – 8.5 kgf/cm

)

according to the length of nails and the hardness of

workpiece.

The correct air pressure is the lowest pressure which will

do the job. Using the Nailer at a higher than required air

pressure unnecessarily over stresses the Nailer.

This Hitachi nailer has a STANDARD CONTACT TRIP

MECHANISM (Bounce Fire). An OPTIONAL SEQUENTIAL

TRIP MECHANISM kit (SINGLE SHOT) is available as order

part number 878226.

THE STANDARD CONTACT TRIP MECHANISM (Bounce

Fire) is for use where rapid fastener placement is desired

and must be operated in accordance with the following

“Methods of Operation”.

NOTE:

䢇 Be careful that the final nail can be dropped or driven

at an irregular angle.

METHODS OF OPERATION

This Nailer is equipped with the push lever and does not

operate unless the push lever is depressed (upward

position).

There are two methods of operation to drive nails with

this Nailer.

They are:

1. Intermittent operation (Trigger fire):

2. Continuous operation (Push lever fire):

(1) Intermittent operation (Trigger fire)

1 Position the nail outlet on the workpiece with

finger off the trigger.

2 Depress the push lever firmly until it is completely

depressed.

3 Pull the trigger to drive a nail.

4 Remove finger from the trigger.

To drive another nail, move the Nailer along the

workpiece and repeat this procedure.

(2) Continuous operation (Push lever fire)

1 Pull the trigger with the Nailer off the workpiece.

2 Depress the push lever against the workpiece to

drive a nail.

3 Move the Nailer along the workpiece with a

bouncing motion.

Each depression of the push lever will drive a nail.

As soon as the desired number of nails have been

driven, remove finger from the trigger.

WARNING

䢇 Keep your finger off the trigger except during

fastening operation, because serious injury could

result if the push lever accidentally contacts you

or others in work area.

䢇 Keep hands and body away from the discharge

area. The nailer with contact trip mechanism may

bounce from the recoil of driving a fastener and

unwanted subsequent fastener may be driven,

possibly causing injury.

䢇 Some types of loaded nails can spark out of the

muzzle during a nail driving operation. Exericise

caution!

THE OPTIONAL SEQUENTIAL TRIP MECHANISM (SINGLE

SHOT PARTS) is for use where precision fastener

placement is desired and must be operated in accordance

with the following “Method of Operation”.

You must first depress the push lever (upward

position) where you wnat to drive a nail and then pull

the trigger. After the each nail is driven, completely

release the trigger and lift the tool off the work

surface.

An OPTIONAL SEQUENTIAL TRIP MECHANISM may

reduce the possibility of bodily injury to you or others

in the work area. 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. An OPTIONAL SEQUENTIAL TRIP

MECHANISM may also reduce the speed of operation

compared to the standard contact trip mechanism.

NOTE:

䢇 Both STANDARD CONTACT TRIP MECHANISM and

OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if

used as described above and accroding to all

warnings and instructions.

䢇 Always handle nails and package carefully.

If nails are dropped, collating wire may be damaged

and cut, which will cause mis-feeding and jamming.

䢇 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.

3. Cleaning and removal of tar and dirt

Tar and dirt may build up on the nose and push lever.

This can prevent correct operation.

Clean and remove tar and dirt with kerosene, #2 fuel

oil or diesel fuel.

NEVER USE GASOLINE or other highly flammable

liquids.

Vapor of such liquids inside the Nailer could be

ignited by a spark produced during nailing, which can

cause an explosion.

1 Immerse only the area around the outlet in

solvent.

Do not immerse the magazine or body.

Plastic parts and O-ring may be damaged.

2 Dry off the Nailer before use. Any oil film left after

cleanup will accelerate the tar buildup, and the
