WORKING ENVIRONMENT

WARNING

䢇 No flammable gas, liquid or other

flammable objects at worksite.

䢇 Clear the area of children or

unauthorized personnel.

AIR SUPPLY

DANGER

䢇 NEVER use

oxygen or other bottled gases. Explosion may occur.

1. Power source 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.

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 (N5021A) operating

at 100 psi driving 30 staples per

minute Amount of air required =3 × 30 × .039 (1.1) × 1.2 =4.2 CFM (ft

/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. 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.

COLD WEATHER CARE

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 64 psi (4.4

bar 4.5 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.

CAUTION

䢇 Do not free-fire the Stapler at high

pressure.

TESTING THE STAPLER

DANGER

䢇 Operators and

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

WARNING

䢇 Never use Stapler unless push lever is

Trigger

Push lever

(2) Continuous operation (Push lever fire)

WARNING

䢇 To avoid double firing or accidental

firing due to recoil.

— 15 —

English

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

Push lever

WARNING

䢇 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.

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 according to all warnings and instructions.

䢇 Always handle staples and package

carefully. If staples are dropped, collating bond may be broken.

䢇 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

䢇 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

— 16 —

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.
