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 Stapler in explosive

atmospheres, such as in the presence of

ﬂ ammable liquids, gases, or combustible dust.

The Stapler is able to create sparks resulting in the

ignition of the dust or fumes.

(3) Keep bystanders, children, and visitors away

while operating the Stapler. Distractions are able

to result in the loss of control of the Stapler.

2. Personal safety

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

sense when working with the Stapler. Do not use

the Stapler while tired, after having consumed

drugs or alcohol, or while under the inﬂ uence of

medication.

A moment of inattention while operating the Stapler

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 Stapler with your ﬁ nger on the switch or

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

(4)

– Disconnect the Stapler

from the air source before making adjustments,

doing Stapler maintenance, clearing jams,

touching the Push Lever, attaching or removing

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

leaving the Stapler outside of the operator's

supervision or control, loading, or unloading the

Stapler, handing it to another person, elevating,

lowering or otherwise moving the Stapler to a

new location. Never attempt to clear a jam or repair

the Stapler unless you have disconnected air hose

from the Stapler and removed all remaining fasteners

from the Stapler. The Stapler should never be left

unattended since people who are not familiar with the

Stapler 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 Stapler 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.

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

Attach the hose to the structure to reduce the risk of

loss of balance if the hose shifts.

(10)

– Drive Staples into proper

work surface only. Do not drive staple into other

staples. This is able to cause the fastener to be

deﬂ ected and hit someone, or cause the Stapler to

react and result in a risk of injury to persons.

3. Stapler 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 Stapler. Use the correct Stapler

for the application. The correct Stapler will do the job

better and safer at the rate for which the Stapler is

designed.

English

SAFETY — Continued

WARNING

(3) Do not use the Stapler if the switch does not turn

the Stapler on or oﬀ . Any Stapler that cannot be

controlled with the switch is dangerous and must be

repaired.

Never use Stapler which is defective or operating

abnormally. If the Stapler 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 Stapler from the air source

before making any adjustments, changing

accessories, or storing the Stapler. Such

preventive safety measures reduce the risk of starting

the Stapler unintentionally.

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

children and other untrained persons. A Stapler

is dangerous in the hands of untrained users.

(6) Maintain the Stapler with care. Keep the

Stapler 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 Stapler's operation.

If damaged, have the Stapler serviced before using.

Because of high air pressure in the Stapler, cracks

in the surface are dangerous. To avoid this, do not

drop the Stapler or strike the Stapler against hard

surfaces; and do not scratch or engrave signs on

the Stapler. Many accidents are caused by poorly

maintained Staplers. There is a risk of bursting if the

Stapler is damaged.

(8) Do not use the Stapler 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 Stapler. Use of an

accessory not intended for use with the speciﬁ c

Stapler, 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 Stapler by Hitachi are

able to result in a risk of injury to persons or Stapler

damage when used in this Stapler.

4. Service

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

repair personnel.

(2) When servicing a Stapler, use only identical

replacement parts. Use only authorized parts.

(3) Use only the lubricants supplied with the Stapler

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 Stapler is able to result in

bursting, abnormal operation, breakage of the

Stapler 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 Stapler.

Always verify prior to using the Stapler 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 Stapler. Such

gases are capable of explosion and serious injury to

persons.

6. Others

(1) Before starting work, check the stapling

operation switching device.

This Hitachi stapler includes a stapling operation

switching device.

Before starting work, check the setting of the

operation switching device.

If the switching device is not set properly, the Stapler

will not operate correctly.

(2) Always select the switching device that is

appropriate to the application and the training of

the operator.

6

English

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

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

a staple, the Stapler 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 Stapler.

2) allowing recoil to move the Stapler away from

work surface.

3) not resisting recoil such that the Stapler 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

staple 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 Stapler against the wood with

excessive force.

3

Separate the Stapler from the wood as it

recoils after stapling

4) keeping face and body parts away from the

Stapler.

(4) Never Use NON relieving coupler on Stapler.

If a non relieving coupler is used on the Stapler,

the Stapler can remain charged with air after

disconnecting and thus will be able to drive a fastener

even after disconnecting. The Stapler and air hose

must have a hose coupling such that all pressure is

removed from the Stapler when the coupling joint is

disconnected.

(5) 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 Stapler unless the

Push Lever is operating properly, otherwise the

Stapler could drive a fastener unexpectedly. Do not

tamper with or remove the Push Lever, or otherwise

cause the Push Lever to become inoperable.

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

all screws and covers tightly mounted.

Check their condition periodically. Never use the

Stapler if parts are missing or damaged.

(7) Do not load fasteners with Trigger or Push Lever

depressed. When loading fasteners into the Stapler

or when connecting the air hose,

1) do not depress the Trigger;

2) do not depress the Push Lever; and

3) keep the Stapler pointed downward.

(8) 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.

(9) 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.

(10) 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.

(11) Use extra caution when driving the Stapler into

existing walls or other blind areas to prevent

contact with hidden objects or persons on other

side (eg., wires, pipes).

(12) 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.

(13) Do not lift, pull or lower the Stapler by the hose.

(14) Do not disconnect air hose from Stapler with

ﬁ nger on Trigger. The Stapler can ﬁ re when

reconnected to An air supply.

(15) Handle Stapler correctly. Operate the Stapler

according to this Manual. Never allow the Stapler to

be operated by children, individuals unfamiliar with its

operation or unauthorized personnel.

(16) Never use Stapler for applications other than

those speciﬁ ed in this manual.

(17) Never modify or alter a Stapler. Doing so may

cause it to malfunction and personal injuries may

result.

Read section titled “SAFETY”(pages 4 – 8).

DANGER

●

Operators and others in work

area MUST wear safety

glasses with side shields

which conforms to ANSI Z87.1

speciﬁ cations.

Ordinary eyeglasses do not

provide adequate protection.

ADJUSTING AIR PRESSURE

WARNING

●

Do not exceed 120 psi (8.3 bar 8.5 kgf/cm

2

).

Adjust the air pressure at recommended operating

pressure 70 – 120 psi (4.9 – 8.3 bar 5 – 8.5 kgf/cm

2

)

according to the length of staples and the hardness of

workpiece.

The correct air pressure is the lowest pressure which will

do the job. Using the Stapler at a higher than required air

pressure unnecessarily over stresses the Stapler.

LOADING STAPLES

WARNING

●

When loading staples into Stapler,

1) do not pull trigger;

2) do not depress push lever; and

3) keep Stapler pointed downward.

(1) Pull the staple feeder backward, and conﬁ rm that

After stapling:

1) disconnect air hose from the Stapler;

2) remove all staples from the Stapler;

3) supply 5 – 10 drops of Hitachi pneumatic tool

lubricant into the air plug on the Stapler; and

4) open the petcock on the air compressor tank to

drain any moisture.

ADJUSTING THE STAPLING DEPTH

WARNING

●

When adjusting the Adjuster, be sure to

remove your ﬁ nger from the trigger and

disconnect the air hose from the stapler.

To assure that each staple penetrates to the same depth,

be sure that:

1) the air pressure to the Stapler remains constant

(regulator is installed and working properly), and

2) the Stapler is always held ﬁ rmly against the

workpiece.

If staples are driven too deep or shallow into the

workpiece, adjust the stapling in the following order.

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. The Stapler with contact trip

mechanism may bounce from the recoil of

driving a fastener and unwanted subsequent

fastener may be driven, possibly causing

injury.

●

Some types of loaded staples can spark

out of the muzzle during a staple 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 staple 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 three systems:

SINGLE SEQUENTIAL ACTUATION MECHANISM,

CONTACT ACTUATION MECHANISM.

●

Always handle staples and package carefully. If

staples are dropped, collating bond may be broken,

which will cause mis-feeding and jamming.

6

Choose a suitable position for the adjuster.

NOTE:

●

The staple might not drive deep enough if using high

pressure with the adjuster set upwards (shallow side)

due to factors such as the material hardness or staple

type.

If that happens, reduce pressure and set the adjuster

to lowest position so the staple drives in at a good

position.
