DANGER When operating the Stapler, always wear eye protec- tor, and make sure others in work area wear eye protector, too. Eye protector 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 eye protector by the Stapler operator and others in work area. 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 Do not exceed maximum recommended air pressure 120 psi (8.3 bar 8.5 kgf/cm

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

) as the Stapler can burst.

Always assume the Stapler contains fasteners. Never point the Stapler toward yourself or anyone else, 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.

5. NEVER CARRY WITH FINGER ON TRIGGER.

Remove finger from trigger when not driving fasteners. 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.

6. ALWAYS WEAR EAR AND HEAD PROTECTOR.

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

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

8. KEEP WORK AREA CLEAN.

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

9. 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.

10. 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.

12. 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.

13. 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.

14. 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.

15. 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.

16. 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.

17. 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.

18. HOLD STAPLER FIRMLY TO MINIMIZE RECOIL.

Recoil can result in a second fastener being driven unintentionally.

19. 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.

20. 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.

21. 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.

24. 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.English

BEFORE OPERATION Read section titled “SAFETY” (pages 4 – 6). Make sure of the followings before operation. 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 oxygen, combusti- ble gases or any other bot- tled gases. WARNING ● 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.English

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.

䡬 The Stapler can be installed as follows: Remove the dust cap placed at the air inlet. Install a 3/8 NPT male plug at the air inlet. 䡬 A female coupler must be on the air hose. The hose coupling (male plug-female coupler) must remove all pressure from the Stapler when disconnected. Stapler use a non relieving coupler on the Stapler.

Using the Air consumption table and the Air compressor size formula, find a correct compressor size. 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 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) psi 80 90 100 Operating pressure (bar) (5.5) (6.2) (6.9) (kgf/cm

Example: 3 Staplers (N5008AB) operating at 100 psi driving 30 staples per minute Amount of air required =3 × 30 × .046 (1.3) × 1.2 =5.0 CFM (ft

/min) (140 ltr/min) After making the calculations as shown above, you should find a compressor providing 5 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 2 – 3 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. ● Always wear eye protector. CAUTION: ● Do not free-fire the Stapler at high pressure.

● Never use Stapler unless push lever is operating properly. DANGER WARNINGEnglish

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. 䡺 ALL SCREWS MUST BE TIGHTENED. If any screws are loose, tighten them.

Connect the air hose. Do not load any staples in the Stapler. 䡺 THE STAPLER MUST NOT LEAK AIR. Hold the Stapler downward and pull the trigger. 䡺 THE STAPLER MUST NOT OPERATE. Pull TriggerEnglish

(3) With finger off the trigger, depress the push lever against the workpiece. 䡺 THE STAPLER MUST NOT OPERATE. (4) Without touching the trigger, depress the push lever against the workpiece. Pull the trigger.

䡺 THE STAPLER MUST OPERATE

(5) With the Stapler off the workpiece, pull the trigger. Depress the push lever against the workpiece. 䡺 THE STAPLER MUST OPERATE. (6) If no abnormal operation is observed, you may load staples in the Stapler.
