1. OPERATORS AND OTHERS IN WORK AREA MUST 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.

2. NEVER USE OXYGEN OR OTHER BOTTLED 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.

4. KEEP FINGERS AWAY FROM TRIGGER WHEN NOT DRIVING FASTENERS TO AVOID

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 18 of “METHODS OF OPERATION.”English

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.

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. SAFETY — Continued WARNINGEnglish

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 HANDS AND FEET AWAY FROM FIRING HEAD DURING USE.

Never place your 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. 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,

1) do not push the Stapler on the workpiece with strong force;

2) take the Stapler completely away from the workpiece using recoil, and keep the

push lever away from the workpiece until the next desirable shot; and

3) pull the trigger and release it QUICKLY when performing intermittent operation

WORKPIECE. The fasteners can be driven through or away from the workpiece and hit someone.

21. 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.

22. 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

25. 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.

26. DO NOT DISCONNECT AIR HOSE FROM STAPLER WITH FINGER ON TRIGGER.

AIR SUPPLY DANGER 䢇 NEVER use oxygen or other bottled gases. Explosion may occur. WARNING 䢇 Never connect Stapler to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm

䡬 Use only clean, dry, regulated compressed air as a power source for this Stapler. 䡬 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.” 䡬 Moisture or oil in the air compressor may accelerate wear and corrosion in the Stapler. Drain daily.

2. Filter-Regulator-Lubricator

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

䡬 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. Stapler Side Filter Lubricator Compressor Side RegulatorEnglish

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

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

Using the Air consumption table and the Air compressor size formula, find a correct compressor size. Air consumption table 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 (N3804AB2) operating at 100 psi driving 30 staples per minute Amount of air required =3 × 30 × .027 (.78) × 1.2 =3.0 CFM (ft

/min) (84 ltr/min) After making the calculations as shown above, you should find a compressor providing

3.0 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. 䡬 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. 䡬 Filter-regulator-lubricator units should always be used. Keep the lubricator filled with Hitachi pneumatic tool lubricant. 䡬 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.

䡬 Do not store the Stapler in a cold weather environment. Keep the Stapler in a warm area until beginning the work. 䡬 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 40 psi (2.8 bar 2.8 kgf/cm

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. psi 80 90 100 Operating pressure (bar) (5.5) (6.2) (6.9) (kgf/cm

This Hitachi Stapler has a STANDARD CONTACT TRIP MECHANISM (Bounce File). An OPTIONAL SEQUENTIAL TRIP MECHANISM kit (SINGLE SHOT) is available as order part number 882332. THE STANDARD CONTACT TRIP MECHANISM (Bounce Fire) is for use where rapid fastener placement is desired and must be operated in accordance with the following “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. 2 Depress 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 fire) 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. WARNING 䢇 Keep your finger off the trigger except during fastening operation, beacuse serious injury could result if the push lever accidentally contacts you or others in work area. 䢇 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. 䢇 Some types of loaded staples can spark out of the muzzle during a nail 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: 䢇 Both STANDARD CONTACT TRIP MECHANISM and OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if used as described above and accroding to all warnings and instructions. 䢇 Always handle staples and package carefully. If staples are dropped, collating bond may be broken. Push Lever Previously pull the trigger
