English 000BookN3808APNAlowes.indb4000BookN3808APNAlowes.indb4 2018/03/0912:11:282018/03/0912:11:28SAFETY — Continued WARNING When using tools, basic precautions should always be followed, Including the following:

(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.

(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, affi xing the hook, 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 and caps 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. Head protection shall conform to ANSI Z89.1, "American National Standard for Industrial Head Protection." (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 000BookN3808APNAlowes.indb5000BookN3808APNAlowes.indb5 2018/03/0912:11:282018/03/0912:11:28SAFETY — 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 Staplers, 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.

(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.

(1) Never connect to an air source that is capable of exceeding 200 psi (13.7 bar 14 kgf/cm

) 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/cm

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.

(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.

English 000BookN3808APNAlowes.indb6000BookN3808APNAlowes.indb6 2018/03/0912:11:282018/03/0912:11:28(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

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)

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 Stapler against the workpiece with excessive force.

Separate the Stapler from the workpiece 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. SAFETY — Continued WARNING

Remove fi nger from the trigger. To continue stapling in a separate location, move the stapler along the workpiece, repeating steps

required. Push Lever

A staple 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 stapler against the

workpiece with excessive force.

2) Separate the stapler from the workpiece

as it recoils after stapling.

If the hook is affi xed, do not operate with CONTACT ACTUATION MECHANISM.

Pull the trigger with the Stapler off the workpiece.

Depress the push lever against the workpiece to drive a staple.

Move the Stapler along the workpiece with a bouncing motion. Each depression of the push lever will drive a staple. As soon as the desired number of staples have been driven, remove fi nger from the trigger.

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

Always handle staples and package carefully. If staples are dropped, collating bond may be broken, which will cause mis-feeding and jamming.

1) disconnect air hose from the Stapler;

2) remove all staples and caps 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. Examples of irregular feed for the Caps and countermeasures to remedy it are shown below.

1. Cut while connecting

Remove the caps with your fi nger or other object.

Confi rm that the caps are correctly positioned. If it is not, adjust cap position. (Refer to Loading Caps on page 16.)

2. Cutting defects during stapling

Remove the caps with your fi nger or other object.

Confi rm that the caps is correctly positioned. If it is not, adjust cap position. (Refer to Loading Caps on page 16.)

ADJUSTING THE STAPLING DEPTH

Disconnect the air hose from the stapler before turning the adjuster. 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.

If staples are driven too deep, turn the adjuster to the shallow side. If staples are driven too shallow, turn the adjuster to the deep side. Turn Adjuster Flush Too Deep

Stop turning the adjuster when a suitable position is reached for a stapling test.

Connect the air hose. ALWAYS WEAR SAFETY GLASSES. Perform a stapling test.

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.

Disconnect the air hose from the stapler before turning the top cover. The direction of the exhaust vent can be changed by turning the top cover. Exhaust vent Top cover HOOK With the N3808AP, an included hook can be attached by using M5 bolts which are included with the tools. When the tool is detached from the hose and not in use, the hook can be used to store the unit. WARNING

When attaching or detaching the hook, contact Hitachi Authorized Service Centers.

When the hook is attached, operate only with SINGLE SEQUENTIAL ACTUATION MECHANISM and not with CONTACT ACTUATION MECHANISM. For switching between SINGLE SEQUENTIAL and CONTACT, see the appropriate section in “STAPLER OPERATION”.

Do not hook on high or unstable locations. Also, do not hook it to the body, clothing, belt or other personal items.
