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.

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 includas 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 OPERATION

Read section titled “SAFETY” (pages 4 – 7).

DANGER

●

Operators and others in work

area MUST wear safety glasses with side shields which conforms to ANSI Z87.1 speciﬁ cations.

WARNING

●

NEVER point tool at yourself or others in

work area.

●

Keep ﬁ ngers AWAY from trigger when not

driving nails to avoid accidental ﬁ ring.

●

Choice of triggering method is important.

Please read and understand “Methods of

Operation” below.

●

Before starting work, check the nailing

operation switching device.

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; and

4) handing it to another person.

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.

First, 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 upward 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 upward position

(to set to SINGLE SEQUENTIAL ACTUATION MECHANISM).

(Set the switching device to the upward 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.

Upward position

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 downward position

(to set to CONTACT ACTUATION MECHANISM).

(Set the switching device to the downward

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.

English

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 wire 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.

ADJUSTING THE NAILING DEPTH

WARNING

●

Disconnect the air hose from the nailer

before turning the adjuster.

To assure that each nail penetrates to the same depth, be sure that:

1) the air pressure to the Nailer remains constant (regulator is installed and working properly), and

2) the Nailer is always held ﬁ rmly against the workpiece.

If nails are driven too deep or shallow into the workpiece, adjust the nailing in the following order.

DISCONNECT AIR HOSE FROM NAILER

Adjuster

Shallow

If nails are driven too deep, turn the adjuster to the

shallow side.

Adjustments are in half-turn increments.

Too Deep

If nails are driven too shallow, turn the adjuster to the

deep side.

Too Shallow

Stop turning the adjuster when a suitable position is

reached for a nailing test.

Connect the air hose. ALWAYS WEAR EYE PROTECTION. Perform a nailing test.
