Make sure of the following 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 or other bottled gases. Explosion may occur.

WARNING

●Never connect Stapler to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm²).

●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.

Regulator Stapler Side Compressor Side Filter Lubricator

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.

3. Air hose

Air hose must have a minimum working pressure rating of 150 psi (10.4 bar 10.6 kgf/cm ^2 ) or 150% of the maximum pressure produced in the system, whichever is higher.

4. Air consumption

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

Air consumption table

	psi 80 90 100
Operating pressure (bar) (5.5) (6.2) (6.9) (kgf/cm2) (5.6) (6.3) (7)
Air consumption	ft3/cycle .019 (ltr/cycle) (.54) (.67) (78)

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

$$ \begin{array}{l} = 3 \times 3 0 \times . 0 2 7 (. 7 8) \times 1. 2 \ = 3. 0 \text { CFM } (\mathrm{ft} ^ {3} / \min) (8 4 \mathrm{ltr} / \min) \ \end{array} $$

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.

○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.

①Reduce the air pressure to 40 psi (2.8 bar 2.8 kgf/cm ^2 ).
②Remove all staples from the Stapler.
③Connect 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.

TESTING THE STAPLER

DANGER

Simple line drawing of a person wearing sunglasses (no text or symbols)

●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.

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

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)

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

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

Push Lever Trigger

(2) Continuous operation (Push lever fire)

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

Push Lever Previously pull 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 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:

●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

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.

①DISCONNECT AIR HOSE FROM STAPLER.

Adjuster ①⑤ Disconnect air hose

②If staples are driven too deep, turn the adjuster to the shallow side.

Adjustments are in half-turn increments.
