WEAR SAFETY GLASSES WITH SIDE SHIELDS. When operating the Stapler, always wear safety glasses with side shields, and make sure others in work area wear safety glasses, too. Safety glasses must conform to the requirements of American National Standards Institute, ANSI Z87.1 and provide protection against flying particles both from the front and side. The employer must enforce the use of safety glasses by the Stapler operator and others in work area. SAFETY

GASES. EXPLOSION MAY OCCUR. Never use oxygen, combustible gases or any other bottled gases as a power source for the Stapler. Use of the above gases is dangerous, as the Stapler will explode. Use only clean, dry, regulated compressed air. WARNING

3. NEVER POINT TOOL AT YOURSELF OR OTHERS

IN WORK AREA. Always assume the Stapler contains fasteners. Never point the Stapler at yourself toward yourself or others, whether it contains fasteners or not. If fasteners are mistakenly driven, it can lead to severe injuries. Never engage in horseplay with the Stapler. Respect the Stapler as a working implement.

ACCIDENTAL FIRING. Never carry the Stapler with finger on trigger since you could drive a fastener unintentionally and injure yourself or someone else. Always carry the Stapler by the handle only.

5. CHOICE OF TRIGGERING METHOD IS

IMPORTANT. Please read and understand page 13 of “METHODS OF OPERATION.”

Never connect the Stapler to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm

as the Stapler can burst.

7. ALWAYS WEAR EAR AND HEAD PROTECTION.

Always wear ear protection to protect your ears from loud noise. Always wear head protection to protect your head from flying objects.

8. STORE STAPLER PROPERLY.

When not in use, the Stapler should be stored in a dry place. Keep out of reach of children. Lock the storage area.

9. KEEP WORK AREA CLEAN.

Cluttered areas invite injuries. Clear all work areas of unnecessary tools, debris, furniture, etc.

10. NEVER USE IN PRESENCE OF FLAMMABLE

LIQUIDS OR GASES. The Stapler produces sparks during operation. Never use the Stapler in sites containing lacquer, paint, benzine, thinner, gasoline, gases, adhesive agents, and other materials which are combustible or explosive.English

SAFETY — Continued WARNING

11. KEEP VISITORS AWAY.

Do not let visitors handle the Stapler. All visitors should be kept safely away from work area.

Do not wear loose clothing or jewelry as they can be caught in moving parts. Rubber gloves and nonskid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair.

13. 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.

14. CHECK PUSH LEVER BEFORE USE.

Make sure the push lever operates properly. (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, otherwise the push lever becomes inoperable.

15. 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.

16. DO NOT LOAD FASTENERS WITH TRIGGER

PULLED OR PUSH LEVER DEPRESSED. When loading fasteners into the Stapler or when connecting the air hose,

1) do not pull the trigger;

2) do not depress the push lever; and

3) keep the Stapler pointed downward.

17. KEEP FACE, HANDS AND FEET AWAY FROM

FIRING HEAD AT ALL TIMES. Never place your face, hands or feet closer than 8 inches (200 mm) from the firing head. A serious injury can result if the fasteners are deflected by the workpiece, or are driven away from the point of entry.

18. PLACE STAPLER PROPERLY ON WORKPIECE.

Do not drive fasteners on top of other fasteners or with the Stapler at too steep of an angle; the fasteners can ricochet and hurt someone.

19. BEFORE STARTING WORK, CHECK THE

FASTENING OPERATION SWITCHING DEVICE. This Hitachi stapler includes a fastening 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.

20. BE CAREFUL OF DOUBLE FIRE 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 fire,

Intermittent operation (Trigger firing)

1) Set the switching device to SINGLE

ACTUATION MECHANISM.

2) Pull the trigger rapidly and firmly.

Continuous operation (Push lever firing)

1) Do not press the stapler against the workpiece

with excessive force.

2) Separate the stapler from the workpiece as it

recoils after fastening.

21. 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.

22. 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.

23. 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. Turn off the breaker switch to ensure there are no live wires.

Keep proper footing and balance at all times

26. 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.

27. DO NOT DISCONNECT AIR HOSE FROM STAPLER

WITH FINGER ON TRIGGER. The Stapler can fire when re-connected to an air supply.English

SAFETY — Continued WARNING

28. DISCONNECT AIR HOSE FROM STAPLER WHEN:

1) doing maintenance and inspection;

2) loading fasteners;

3) turning the adjuster and top cover;

4) attaching or removing the nose cap;

6) it is not in use;

7) leaving work area;

8) moving it to another location; and

9) handing it to another person.

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.

Watch what you are doing. Use common sense. Do not operate the Stapler when you are tired. The Stapler should never be used by you if you are under the influence of alcohol, drugs or medication that makes you drowsy.

No flammable gas, liquid or other flammable objects at worksite.

Clear the area of children or unauthorized personnel. AIR SUPPLY DANGER

NEVER use oxygen or other bottled gases. Explosion may occur. WARNING

Never connect Stapler to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm

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.

Use a regulator with a pressure range of 0 – 120 psi (0 – 8.3 bar 0 – 8.5 kgf/cm

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. Inspect the lubricator before operation to be sure the supply of lubricant is adequate. Use Hitachi pneumatic tool lubricant.

Air hose must have a minimum working pressure rating of 150 psi (10.4 bar 10.6 kgf/cm

) or 150% of the maximum pressure produced in the system, whichever is higher.

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.

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.

Reduce the air pressure to 40 psi (2.8 bar 2.8 kgf/cm

Remove all staples from the Stapler.

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-fire the Stapler at high pressure.

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

Never use Stapler unless push lever is operating properly. Before actually beginning the stapling work, test the Stapler by using the checklist below. Conduct the tests in the following order. If abnormal operation occurs, stop using the Stapler and contact a Hitachi authorized service center immediately. (1) DISCONNECT AIR HOSE FROM STAPLER. REMOVE ALL STAPLES FROM STAPLER.

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) Use the SINGLE ACTUATION MECHANISM setting. WARNING

Unlike the FULL SEQUENTIAL ACTUATION MECHANISM, please note that the SINGLE ACTUATION MECHANISM of this Hitachi nailer will drive a nail each time the push lever is pressed against the wood as long as the trigger is pressed.

For intermittent operation, set the switching device to the upward position completely. (i.e. Set to SINGLE ACTUATION MECHANISM.)

To avoid double firing or accidental firing due to recoil.

1) Set the switching device to SINGLE

ACTUATION MECHANISM.

2) Pull the trigger rapidly and firmly.

Set the switching device to the upward position (to set to SINGLE ACTUATION MECHANISM). (Set the switching device to the upward position completely as shown in the diagram.English

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 finger from the trigger. 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 FULL SEQUENTIAL ACTUATION MECHANISM

(SEQUENTIAL TRIP MECHANISM) is for use where precision fastener placement is desired and must be operated in accordance with the following “Method of Operation”. Otherwise, it will be set to CONTACT ACTUATION MECHANISM.)

Position the staple outlet on the workpiece with finger off the trigger.

Depress the push lever firmly until it is completely depressed.

Pull the trigger to drive a staple.

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

as required. (2) Continuous operation (Push lever fire) Using CONTACT ACTUATION MECHANISM 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.

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.) Switching device

Previously pull the trigger Switching device

You must first depress the push lever (upward position) where you wnat to drive a nail and then pull the trigger. After the each nail is driven, completely release the trigger and lift the tool off the work surface. An FULL SEQUENTIAL

ACTUATION MECHANISM (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 nail if you keep the trigger pulled and accidentally bump the push lever against yourself or others. An OPTIONAL SEQUENTIAL TRIP MECHANISM may also reduse the speed of operation compared to the standard contact trip mechanism. NOTE:

If all warnings and instructions are followed, safe operation is possible with all three systems:

SINGLE ACTUATION MECHANISM, CONTACT

ACTUATION MECHANISM and FULL 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 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

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.

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.

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 air hose

When changing the exhaust direction, be sure to remove your finger from the trigger and disconnect the air hose from the stapler. The direction of the exhaust vent can be changed by turning the top cover.

When detaching or attaching the nose cap, be sure to remove your finger from the trigger and disconnect the air hose from the stapler. Exhaust vent Top cover
