IMPORTANT SAFETY INSTRUCTIONS - FOR USING NAILERS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS

●

General

To reduce the risks of electric shock, ﬁ re, and injury to persons, READ ALL THE INSTRUCTIONS BEFORE USING

THE TOOL.

DANGER

1. OPERATORS AND OTHERS IN WORK AREA

MUST WEAR EYE PROTECTION (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 ﬂ ying particles

both from the front and side.

Ordinary eyeglasses do not provide

adequate protection.

The employer must enforce the use of

safety glasses by the Nailer operator and

others in work area.

2. NEVER USE REACTIVE GASES OR OTHER

BOTTLED GASES. EXPLOSION MAY OCCUR.

Never use reactive gases such as

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

4. DO NOT PLACE FINGER ON TRIGGER AND KEEP

FINGERS AWAY FROM TRIGGER WHEN NOT

DRIVING FASTENERS TO AVOID ACCIDENTAL

DISCHARGE.

Never carry the Nailer with ﬁ nger on Trigger since

you could drive a fastener unintentionally and injure

yourself or someone else.

Always carry the Nailer by the handle only.

5. KNOW AND UNDERSTAND WHAT TRIGGER

SYSTEM YOU ARE USING.

Read and understand section titled “METHODS OF

OPERATION.” (pages 15 – 17)

6. DO NOT MAKE CONTACT WITH SAFETY TIP

(PUSH LEVER) WHEN NOT DRIVING FASTENERS.

3. NEVER POINT TOOL AT YOURSELF OR OTHERS

IN WORK AREA.

Always assume that the Nailer contains

fasteners.

Never point the Nailer 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.

English

1. Work area

(1) Keep the work area clean and well lighted.

Cluttered benches and dark areas increase the risks

of electric shock, ﬁ re, and injury to persons.

(2) Do not operate the Nailer in explosive

atmospheres, such as in the presence of

ﬂ ammable liquids, gases, or combustible dust.

The Nailer is able to create sparks resulting in the

ignition of the dust or fumes.

(3) Keep bystanders, children, and visitors away

while operating the Nailer. Distractions are able to

result in the loss of control of the Nailer.

2. Personal safety

(1) Stay alert. Focus on your work and use common

sense when working with the Nailer. Do not use

the Nailer while tired, after having consumed

drugs or alcohol, or while under the inﬂ uence of

medication.

A moment of inattention while operating the Nailer

increases the risk of injury to persons.

(2) Dress properly. Do not wear loose clothing or

jewelry. Contain long hair. Keep hair, clothing,

and gloves away from moving parts.

Loose clothes, jewelry, or long hair increases the

risk of injury to persons as a result of being caught in

moving parts.

(3) Avoid unintentional starting. Be sure the switch

is oﬀ before connecting to the air supply. Do

not carry the Nailer with your ﬁ nger on the switch or

connect the Nailer to the air supply with the switch on.

(4)

– Disconnect the Nailer from

the air source before making adjustments, doing

Nailer maintenance, clearing jams, touching

the Push Lever, attaching or removing the nose

cap, when not in use, leaving work area, leaving

the Nailer outside of the operator's supervision

or control, loading, or unloading the Nailer,

handing it to another person, elevating, lowering

or otherwise moving the Nailer to a new location.

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.

Such precautionary measures reduce the risk of

injury to persons.

(5) Do not overreach. Keep proper footing and

balance at all times. Proper footing and balance

enables better control of the Nailer in unexpected

situations.

(6) Use safety equipment. A dust mask, non-skid

safety shoes and a hard hat must be used for the

applicable conditions.

(7)

– Risk of hearing loss. Wear

hearing protection. Hearing protection shall

have a Noise Reduction Rating (NRR) determined

in accordance with US Environmental Protection

Agency rules that is appropriate for noise exposure..

(8) Always wear head protection.

Always wear head protection to protect your

head from ﬂ ying objects.

Head protection shall conform to ANSI Z89.1,

"American National Standard for Industrial Head

Protection."

(9) Do not attach the hose or Nailer to your body.

Attach the hose to the structure to reduce the risk of

loss of balance if the hose shifts.

(10)

– Drive Nails into proper work

surface only. Do not drive nail into other nails. This

is able to cause the fastener to be deﬂ ected and hit

someone, or cause the Nailer to react and result in a

risk of injury to persons.

3. Nailer use and care

(1) Use clamps or another practical way to secure

and support the workpiece to a stable platform.

Holding the work by hand or against the body is

unstable and is able to lead to loss of control.

(2) Do not force the Nailer. Use the correct Nailer for

the application. The correct Nailer will do the job

better and safer at the rate for which the Nailer is

designed.

(3) Do not use the Nailer if the switch does not

turn the Nailer on or oﬀ . Any Nailer that cannot be

controlled with the switch is dangerous and must be

repaired.

SAFETY — Continued

WARNING

When using tools, basic precautions should always be followed, Including the following:

5

English

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.

(4) Disconnect the Nailer from the air source before

making any adjustments, changing accessories,

or storing the Nailer. Such preventive safety

measures reduce the risk of starting the Nailer

unintentionally.

(5) Store the Nailer when it is idle out of reach of

children and other untrained persons. A Nailer is

dangerous in the hands of untrained users.

(6) Maintain the Nailer with care. Keep the

Nailer Clean and lubricated for better and safer

performance.

(7) Check for misalignment or binding of moving

parts, breakage of parts, and any other condition

that may aﬀ ect the Nailer's operation.

If damaged, have the Nailer serviced before using.

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.

Many accidents are caused by poorly maintained

Nailers. There is a risk of bursting if the Nailer is

damaged.

(8) Do not use the Nailer that is not in proper

working order. Tags and physical segregation

shall be used for control.

(9) Use only accessories that are identiﬁ ed by

Hitachi for the speciﬁ c Nailer. Use of an accessory

not intended for use with the speciﬁ c Nailer ,

increases the risk of injury to persons.

(10) Use only those fasteners listed in the

Accessories section of this manual. Fasteners not

identiﬁ ed for use with this Nailer by Hitachi are able to

result in a risk of injury to persons or Nailer damage

when used in this Nailer.

4. Service

(1) Tool service must be performed only by qualiﬁ ed

repair personnel.

(2) When servicing a Nailer, use only identical

replacement parts. Use only authorized parts.

(3) Use only the lubricants supplied with the Nailer

or speciﬁ ed by Hitachi.

5. Air source

(1) Never connect to an air source that is capable

of exceeding 200 psi (13.7 bar 14 kgf/cm

2

) if a

regulator fails.

Over pressurizing the Nailer is able to result in

bursting, abnormal operation, breakage of the Nailer

or serious injury to persons.

DO NOT EXCEED 120 psi (8.3 bar 8.5 kgf/cm

2

).

Use only clean, dry, regulated compressed air at the

rated pressure or within the rated pressure range as

marked on the Nailer.

Always verify prior to using the Nailer that the air

source has been adjusted to the rated air pressure or

within the rated air-pressure range.

(2) Never use reactive gases such as oxygen,

carbon dioxide, combustible gases or any

bottled gas as an air source for the Nailer. Such

gases are capable of explosion and serious injury to

persons.

6. Others

(1) 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.

(2) Always select the switching device that is

appropriate to the application and the training of

the operator.

(3) When switching between SINGLE SEQUENTIAL

and CONTACT, disconnect the air hose and

remove all nails.

(4) When the hook is attached, operate only with

SINGLE SEQUENTIAL ACTUATION MECHANISM

and not with CONTACT ACTUATION MECHANISM.

SAFETY — Continued

WARNING

6

English

(5) Be careful of double ﬁ re and being hit by the

Nailer due to spring back (“recoil”). After driving

a nail, the Nailer may recoil causing it to move away

from the work surface.

To reduce risk of injury always manage recoil by:

1) always maintaining control of the Nailer.

2) allowing recoil to move the Nailer away from work

surface.

3) not resisting recoil such that the Nailer will be

forced back into the work surface. In “CONTACT

ACTUATION MECHANISM”, if push lever is

allowed to re-contact work surface before the

trigger is released, an unintended discharge of a

nail will occur. In order to avoid this undesirable

double ﬁ re,

○

Intermittent operation (Trigger ﬁ re)

1

Set the switching device to SINGLE

SEQUENTIAL ACTUATION MECHANISM.

2

Pull the trigger rapidly and ﬁ rmly.

○

Continuous operation (Push lever ﬁ re)

1

Set the switching device to CONTACT

ACTUATION MECHANISM.

2

Do not press the Nailer against the wood with

excessive force.

3

Separate the Nailer from the wood as it recoils

after nailing.

4) keeping face and body parts away from the Nailer.

(6) 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.

(7) Check Push Lever before use. Make sure the

Push Lever operates properly, and is not inoperable,

disconnected, or altered. (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, or otherwise cause

the Push Lever to become inoperable.

(8) 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.

(9) 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.

(10) Keep hands and body away from ﬁ ring head

during use. Never place your hands or feet closer

than 8 inches (200 mm) from the ﬁ ring head. A

serious injury can result if the fasteners are deﬂ ected

by the workpiece, or are driven away from the point of

entry.

(11) When working close to an edge of a workpiece

or at steep angles, or driving fasteners into

thin workpiece use care to minimize chipping,

splitting or splintering, or free ﬂ ight, ricochet or

piercing of fasteners, which may cause injury.

(12) 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.

(13) Use extra caution when driving the Nailer into

existing walls or other blind areas to prevent

contact with hidden objects or persons on other

side (eg., wires, pipes).

(14) Check for live wires. Avoid the risk of severe

electrical shock by checking for live electrical wires

that may be hidden by walls, ﬂ oors or ceilings. Turn

oﬀ the breaker switch to ensure there are no live

wires.

(15) Do not lift, pull or lower the Nailer by the hose.

(16) Do not disconnect air hose from Nailer with

ﬁ nger on Trigger. The Nailer can ﬁ re when re-

connected to An air supply.

(17) 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.

(18) Never use Nailer for applications other than

those speciﬁ ed in this manual.

(19) Never modify or alter a Nailer. Doing so may cause

it to malfunction and personal injuries may result.

(20) Disconnect the air hose when aﬃ xing the hook.

(21) Do not aﬃ x the hook on high or unstable

locations. Also, do not aﬃ x it to the body,

clothing, belt or other personal items.

WARNING

●

Keep your ﬁ nger oﬀ the trigger except during

fastening operation, because serious injury

could result if the push lever accidentally

contacts you or others in work area.

●

Keep hands and body away from the

discharge area. This Hitachi nailer may

bounce from the recoil of driving a fastener

and unwanted subsequent fastener may be

driven, possibly causing injury.

●

Some types of loaded nails can spark out of

the muzzle during a nail driving operation.

Exericise caution!

The SINGLE SEQUENTIAL ACTUATION MECHANISM

is for use where precision fastener placement is desired.

The SINGLE SEQUENTIAL ACTUATION MECHANISM

may reduce the possibility of bodily injury to you or others

in the work area compared to the CONTACT ACTUATION

MECHANISM. 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.

The SINGLE SEQUENTIAL ACTUATION MECHANISM

may also reduce the speed of operation compared

to the CONTACT ACTUATION MECHANISM. The

SINGLE SEQUENTIAL ACTUATION MECHANISM is

recommended to inexperienced users.

NOTE

●

If all warnings and instructions are followed, safe

operation is possible with all two systems: SINGLE

SEQUENTIAL ACTUATION MECHANISM and

CONTACT ACTUATION MECHANISM.

●

Always handle nails and package carefully. If nails

are dropped, collating plastic may be broken.

●

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.
