(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) WARNING - Drive Staples into proper work surface only. Do not drive staple into other staples. This is able to cause the fastener to be deflected 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.

SAFETY — Continued

WARNING

(3) Do not use the Stapler if the switch does not turn 4. the Stapler on or off. Any Stapler that cannot be controlled with the switch is dangerous and must be repaired. (1)

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 affect 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 identified by Hitachi for the specific Stapler. Use of an accessory not intended for use with the specific Stapler, increases the risk of injury to persons.
(10) Use only those fasteners listed in the Accessories section of this manual. Fasteners not identified 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 qualified 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 specified 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.

120 psi 120 psi

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) Be careful of double fire 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 Staple work surface.

SAFETY — Continued

WARNING

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 fire, (6)

○ Intermittent operation (Trigger fi re)

① Pull the trigger rapidly and firmly.

② Release the trigger QUICKLY.

○ Continuous operation (Push lever fire)

① Do not press the Stapler against the wood with excessive force.

② Separate the Stapler from the wood as it recoils after stapling

4) keeping face and body parts away from the Stapler.

(2) 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 removed from the Stapler when the coupling joint is disconnected. (11)

(3) Check Push Lever before use. Make sure 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.

(4) 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.

(5) 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.

(6) Keep hands and body away from fi ring head ACT 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 deflected by the workpiece, or are driven away from the point of entry.

(7) 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.

(8) 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.

(9) 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).

(10) Check for live wires. Avoid the risk of severe electrical shock by checking for live electrical wires that may be hidden by walls, floors or ceilings. Turnure off the breaker switch to ensure there are no live wires.

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

t(12) Do not disconnect air hose from Stapler with finger on Trigger. The Stapler can fire when reconnected to An air supply.

WORKING ENVIRONMENT

WARNING

● No flammable gas, liquid or other flammable objects at worksite.
● Clear the area of children or unauthorized personnel.

AIR SUPPLY

DANGER

● NEVER use reactive gases or other bottled gases. Explosion may occur.

WARNING

● Never connect Stapler to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm ^2 ) if a regulator fails.
● Never use non relieving coupler on Stapler.

1. Power source

○ Use only clean, dry, regulated compressed air as a power source for this Stapler.
Air compressors used to supply compressed air to this Stapler must comply with the requirements of the latest version of ANSI Standard B 19.3 "Safety Standard For Compressors For Process Industries."

○ Moisture or oil in the air compressor may accelerate wear and corrosion in the Stapler. Drain daily.

1. Filter-Regulator-Lubricator

○ Use a regulator with a pressure range of 0 – 120 psi (0 – 8.3 bar 0 – 8.5 kgf/cm ^2 ).
○ Filter-regulator-lubricator units supply an optimum condition for the Stapler and extend the Stapler life. These units should always be used.

Filter ....The filter removes moisture and dirt mixed in compressed air.

Drain daily unless fitted with an automatic drain.

Keep the filter clean by regular maintenance.

Regulator.....The regulator controls the operating pressure for safe operation of the Stapler. Inspect the regulator before operation to be sure it operates properly.

Lubricator .....The lubricator supplies an oil mist to the Stapler.

Regulator Stapler Side Compressor Side Lubricator Filter

3. Air hose

Compressed air supply hoses shall have a minimum working pressure rating equal to or greater than the pressure from the power source if a regulator fails, or 150 psi (10.4 bar 10.6 kgf/cm ^2 ), whichever is greater.

4. Air consumption

Using the Air consumption table and the Air compressor size formula, find a correct compressor size.

Air consumption table

Operating pressure	psi(bar)(kgf/cm2)	80(5.5)(5.6)	90(6.2)(6.3)	100(6.9)(7)
Air consumption	ft^3 /cycle(ltr/cycle)	.028(.8)	.032(.9)	.039(1.1)

Air compressor size formula

Amount of air required

=number of Staplers

× average staples driven each minute per Stapler
× air consumption at given air pressure
× safety factor (always 1.2)

Example: 3 Staplers (N5010A) operating at 100 psi driving 30 staples per minute

Amount of air required

$$ = 3 \times 3 0 \times . 0 3 9 (1. 1) \times 1. 2 $$

=4.2 CFM (ft³/min) (119 ltr/min)

After making the calculations as shown above, you should find a compressor providing 4.2 CFM of air that is required.

LUBRICATION

It is important that the Stapler be properly lubricated.

Without proper lubrication, the Stapler will not work properly and parts will wear prematurely.

○ Use Hitachi pneumatic tool lubricant.

Do not use detergent oil or additives. These lubricants will harm the O-rings and other rubber parts. This will cause the Stapler to malfunction.

○ Filter-regulator-lubricator units should always be used.

Keep the lubricator filled with Hitachi pneumatic tool lubricant.

☐ If a lubricator is not available, supply 5 – 10 drops of Hitachi pneumatic tool lubricant into the air plug on the Stapler twice a day.

COLD WEATHER CARE

○ Do not store the Stapler in a cold weather environment.

Keep the Stapler in a warm area until beginning the work.

○ If the Stapler is already cold, bring it in a warm area and allow the Stapler to warm up before use.

① Reduce the air pressure to 64 psi (4.4 bar 4.5 kgf/cm²).
② Remove all staples from the Stapler.
③ Connect the air hose and free-fire (blank-fire) the Stapler.

The lowered air pressure will be enough to free-fire the Stapler.

Slow speed operation tends to warm up the moving part.

CAUTION

- Do not free-fi re the Stapler at high pressure.

TESTING THE STAPLER

DANGER

● Operators and others in work area MUST wear safety glasses with side shields which conforms to ANSI Z87.1 specifications.

This Hitachi Stapler has a STANDARD CONTACT TRIP MECHANISM (Bounce Fire). An OPTIONAL SEQUENTIAL TRIP MECHANISM kit (SINGLE SHOT) is available as order part number 876762.

THE STANDARD CONTACT TRIP MECHANISM (Bounce

Fire) is for use where rapid fastener placement is desired and must be operated in accordance with the "Methods of Operation".

METHODS OF OPERATION

This Stapler 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 staples with this Stapler.

They are:

1. Intermittent operation (Trigger fire):
2. Continuous operation (Push lever fire):

(1) Intermittent operation (Trigger fire)

① Position the staple outlet on the workpiece with finger off the trigger.
②Depress the push lever firmly until it is completely depressed.
③ Pull the trigger to drive a staple.
④ Remove finger from the trigger.

To drive another staple, move the Stapler along the workpiece and repeat this procedure.

(2) Continuous operation (Push lever fi re)

WARNING

● To avoid double firing or accidental firing 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.

① Pull the trigger with the Stapler off the workpiece.
② Depress the push lever against the workpiece to drive a staple.
③ 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 finger from the trigger.

Previously pull the trigger ① ③

Push lever

WARNING

• Keep your finger 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 OPTIONAL SEQUENTIAL TRIP MECHANISM (SINGLE SHOT PARTS) is for use where precision fastener placement is desired and must be operated in accordance with the following "Method of Operation".

You must first depress the push lever (upward position) where you want to drive a staple and then pull the trigger. After the each staple is driven, completely release the trigger and lift the tool off the work surface. An OPTIONAL SEQUENTIAL TRIP MECHANISM may reduce the possibility of bodily injury to you or others in the work area. 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. An OPTIONAL SEQUENTIAL TRIP MECHANISM may also reduce the speed of operation compared to the standard contact trip mechanism.

NOTE:

● Both STANDARD CONTACT TRIP MECHANISM and OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if used as described above and according to all warnings and instructions.
● Always handle staples and package carefully. If staples are dropped, collating bond may be broken.
● 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 finger 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 firmly against the workpiece.

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

① DISCONNECT AIR HOSE FROM STAPLER.
