SAFETY — Continued

WARNING

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

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)

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.

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

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 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/cm2).

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.

English

SAFETY — Continued

WARNING

(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)

Set the switching device to SINGLE

SEQUENTIAL ACTUATION MECHANISM.

Pull the trigger rapidly and ﬁ rmly.

○

Continuous operation (Push lever ﬁ re)

Set the switching device to CONTACT

ACTUATION MECHANISM.

Do not press the Nailer against the wood with

excessive force.

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

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.
