IMIPORTANiT SAFETY INSTRUCTIONS

FOR USING ~IAILERS

READ ALL INSTRUCTIONS

~ DANGER

1 . ALWAYS WEAR EYE PROTECTOR.

~,"-~,'¥¥¥~i.~"'

2. NEVER USE BO~LED GASES.

~'

L"i"~i^

When operating the Nailer, always wear eye protector, and make sure

others in work area wear eye protector, too.

Eye protector must conform to the requirements of American National

Standards Institute, ANS[ 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 ciean, dry, regulated compressed air.

~WARNING

3.

DO NOT EXCEED 120 psi.

~~

~,*=:"'¥~~..,::"

Do not exceed maximum recommended air pressure 120 psi (8.3 bar

8.5 kgf/cm2).

Never connect the Nai[er to pressure which potentially exceeds 200 psi

(13.7 bar 14kgf/cm2) as the Nailer can burst.

4. NEVER POENT NAILER TOWARD YOURSELFOR

ANYONE ELSE.

Always assume the Nai[er 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.

6.

NEVER CARRY WITH FENGER 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 hand[e on[y.

ALWAYS WEAR EAR A~D HEAD PROTECTOR.

Always wear ear protector to protect your ears from

loud noise.

Always wear head protector to protect your head from

flying objects.

-4-

I

Li:~~L

7. STORENAILER 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 CLEANi.

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, thinneT, 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.

11.

1 2.

1 3.

1 4.

1 5.

DRESS PROPERLY.

Do not wear ioose clothing or jewe[ry as they can be

oaught in moving parts.

Rubber gloves and nonskid footwear are

recommended when working outdoors.

Wear protective hair covering to contain long hair.

NEVER USE NON REL[EV[NG COUPLER ON

NAILER.

If a non relieving coupler is used on the Nailer, the

Nailer can remain charged with air after disconnecting

and thus wili 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 coupiing joint is disconnected.

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.

KEEP ALL SCREWS AND COVERS TIGHTLY INl

PLACE.

Keep all screws and covers tightly mounted. Check

their condition periodically.

Never use the Nailer if parts are missing or damaged.

DO NOT LOAD FASTENERS WITH TRIGGER OR

PUSH LEVER DEPRESSED.

When loading fasteners into the Nailer or when

conneoting 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 FROMI FIRING

HEAD DURING USE.

Never place your hands or feet cioser than 8 inches

(200 mm) from the firing head.

A serious injury can resuit if the fasteners are

deflected by the workpiece, or are driven away from

the point of entry.

1 7. PLACE NIAILER 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 uninientional[y 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 FASTE~NERS FROMI BOTH StDES

OF A WALL AT THE SAME TIME.

The fasieners can be drive.n 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 eiectrical 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 NAtLER 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.

1 ) doing maintenance and inspection;

2) clearing a jam;

3) it is not in use;

4) Ieaving work area;

5) moving it to another location; and

6) 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 since people

who are not fami[iar with the Nailer might handle it and

injure the themselves.

27. STAY ALERT.

Example: 2 Nailers (NR83A) operating at 100 psi driving

30 nails per minute

Amount of air required

=2 x 30 x .088 (2.5) x I .2

=6.3 CFM (ft3/min) (180 Itr/min)

After making the calculations as shown above, you should

find a compressor providing 6.3 CFM of air that is required.

LUBRICATION

[t is important that the Nailer be properly lubricated.

Without proper lubrication, the Nailer will not work properly

and parts wiil wear prematurely.

O Use Hitachi pneumatic tool lubricant.

Do not use detergent oil or additives. These lubricants will

harm the O-rings and other rubber parts. This wil[ cause

the Nailer to malfunction.

O Filter-regulator-lubricator units should always be used.

Keep the lubricator filled with Hitachi pneumatic tool

lubricant.

O If a lubricator is not available, supply 2 - 3 drops of Hitachi

pneumatic tool lubricant into the air plug on the Nailer

twice a day.

COLD WEATHER CARE

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

Keep the Nailer in a warm area until beginning the work.

O [f the Nailer is aiready cold, bring it in a warm area and

allow the Nailer to warm up before use.

(1) Reduce the air pressure to 40 psi (2.8 bar

2.8 kgf/cm2).

(~)_ Remove ali nails from the Nailer.

(~) 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

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

TESTIN!G THE

NAILER

O Always wear eye protector.

O Never use Nailer unless push lever ls operating

pro periy.

Before actually beginning the nailing work, test the Nailer by

using the checklist below. Conduct the tests in the following

order.

If abnormal operation occurs, stop using the Nailer and

contact a Hitachi authorized service center immediately.

(1) DISCONNECT AIR HOSE FROM NAILER.

REMOVE ALL NAILS FROM NAILER.

Adjust the air pressure at recommended operating pressure

70 - 120 psi (4.9 - 8.3 bar 5 - 8.5 kgflcm2) 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.

LOADING NAILS

O When loading nails into Nailer,

1 ) do not depress trigger;

2) do not depress push lever; and

3) keep Nailer pointed downward.

result if the push iever accidentaliy contacts you or

others in work area.

e Keep hands and body away from the discharge

area. The najier with contact trip mechanism may

bounce from the recoil of driving a faetener and

unwanted subsequent fastener may be driven,

possibly causing injury.

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 want to drive a nail and then pull the trigger.

After the each nail is driven, comp!etely release the trigger

and lift the tool off the work surface.

An OPTIONAL SEQUENTIAL TR[P MECHANISM may

reduse 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

aocidentally bump the push lever against yourself or

others. An OPTIONAL SEQUENTIAL TRIP MECHANISM

may also reduse the speed of operation compared to the

standard contact trip mechanism.

NOTE:

O Both STANDARD CONTACT TRIP MECHANISM and

OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if

used as described above and accroding to all warnings

and instructions.

O Always handle nai!s and package careful[y. If nails are

dropped, co!lating plastic or paper may be broken.

O After nailing:

1) disconnect air hose from the Nailer;

2) remove a]1 nails from the Nailer;

3) supply 2 - 3 drops of Hitachi pneumatic tool lubricant
