OPERATION.” (pages 14 – 16)

6. DO NOT MAKE CONTACT WITH SAFETY

TIP (PUSH LEVER) WHEN NOT DRIVING FASTENERS.

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 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. Watch what you are doing and use

common sense when operating the Nailer. Do not use the Nailer while tired or under the inﬂ uence of drugs, alcohol, or 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.

WARNING

(4)

the air source before making adjustments, doing Nailer maintenance, clearing jams, touching the Push Lever, when not in use, leaving work area, loading, or unloading the Nailer, 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 familiar with the Nailer might handle it and injure the themselves.

Such precautionary measures reduce the risk of

injury to persons.

– Disconnect the Nailer from

(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

Attach the hose to the structure to reduce the risk of

loss of balance if the hose shifts.

WARNING

(10)

workpiece. Do not fasten on top of another fastener.

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.

– Risk of hearing loss. Wear

– Place Nailer properly on

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. 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.

English

SAFETY — Continued

WARNING

(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 aﬀ ects 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) 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.

(9) 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

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 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) Be careful of double ﬁ re 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

ﬁ re,

○

Intermittent operation (Trigger ﬁ ring)

1) Set the switching device to SINGLE SEQUENTIAL ACTUATION MECHANISM.

2) Pull the trigger rapidly and ﬁ rmly.

○

Continuous operation (Push lever ﬁ ring)

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.

(3) 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.

SAFETY — Continued

WARNING

English

(4) 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.

(5) Keep all screws and covers tightly in place. Keep

all screws and covers tightly mounted.

Nailer if parts are missing or damaged.

(6) 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.

(7) Keep hands and feet 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.

(8) 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.

(9) 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.

(10) 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.

(11) Never carry Nailer by hose. (12) Do not disconnect air hose from Nailer with

ﬁ nger on Trigger. The Nailer can ﬁ re when re- connected to An air supply.

This Hitachi nailer includes a nailing

operation switching device.

Before starting work, make sure that the

switching device is properly set.

If the switching device is not set properly, the

nailer will not operate correctly.

●

Never place your hands or feet closer than 8

inches (200 mm) from ﬁ ring head when using.

●

Do not drive nails on top of other nails or

with Nailer at too steep of an angle; nails can ricochet and hurt someone.

●

Do not drive nails into thin boards or near

corners and edges of workpiece. Nails can be driven through or away from workpiece and hit someone.

●

Never drive nails from both sides of a wall

at the same time. Nails can be driven into and through the wall and hit a person on the opposite side.

●

Never use Nailer which is defective or

operating abnormally.

●

Do not use Nailer as hammer.

●

Disconnect air hose from Nailer when:

1) it is not in use;

2) leaving work area;

3) moving it to another location;

4) handing it to another person; and

5) changing switching device.

This Hitachi nailer is equipped with a nailer operation switching device. Use SINGLE SEQUENTIAL ACTUATION MECHANISM or CONTACT ACTUATION MECHANISM in accordance with the work to be performed.

Explanation of the various nailing operations

○

SINGLE SEQUENTIAL ACTUATION MECHANISM:

First, press the push lever against the wood; next, pull the trigger to drive the nail.

After nailing once, nailing will not be possible again

until the trigger is released and pressed again.

○

CONTACT ACTUATION MECHANISM: First, press

the push lever against the wood; next, pull the trigger to drive the nail. Or,

pull the trigger; next, press the push lever against the

wood to drive the nail.

If the trigger is held back, a nail will be driven each

time the push lever is pressed against the wood.

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 ﬁ re):

2. Continuous operation (Push lever ﬁ re):

(1) Intermittent operation (Trigger ﬁ re) Use the SINGLE SEQUENTIAL ACTUATION

MECHANISM setting.

English

WARNING

●

For intermittent operation, set the switching

device to the leftward position completely. (i.e. Set to SINGLE SEQUENTIAL ACTUATION MECHANISM.)

●

To avoid double ﬁ ring or accidental ﬁ ring due

to recoil.

1) Set the switching device to SINGLE SEQUENTIAL ACTUATION MECHANISM.

2) Pull the trigger rapidly and ﬁ rmly.

Set the switching device to the leftward position

(to set to SINGLE SEQUENTIAL ACTUATION MECHANISM).

(Set the switching device to the leftward position

completely as shown in the diagram. Otherwise, it will be set to CONTACT ACTUATION MECHANISM.)

Position the nail outlet on the workpiece with

ﬁ nger oﬀ the trigger.

Depress the push lever ﬁ rmly until it is completely

depressed.

Pull the trigger to drive a nail.

Remove ﬁ nger from the trigger. To continue nailing in a separate location, move the nailer along the wood, repeating steps

– 5 as required.

WARNING

●

A nail will ﬁ re each time the trigger is

depressed as long as the push lever remains depressed.

(2) Continuous operation (Push lever ﬁ re) Using CONTACT ACTUATION MECHANISM

WARNING

●

To avoid double ﬁ ring or accidental ﬁ ring due

to recoil.

1) Do not press the nailer against the wood with excessive force.

2) Separate the nailer from the wood as it recoils after nailing.

Set the switching device to the rightward position

(to set to CONTACT ACTUATION MECHANISM).

(Set the switching device to the rightward position

completely as shown in the diagram. Otherwise, it will not operate properly.)

Pull the trigger with the Nailer oﬀ the workpiece.

Depress the push lever against the workpiece to

drive a nail.

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 ﬁ nger from the trigger.

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. Exercise 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 two systems: SINGLE SEQUENTIAL ACTUATION MECHANISM and CONTACT ACTUATION MECHANISM.

●

Always handle nails and package carefully. If nails

are dropped, collating paper 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.
