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

Staplers, 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

away from work area.

12. DRESS PROPERLY.

Do not wear loose clothing or jewelry as they can be caught in

moving parts. Rubber gloves and nonskid footwear are

recommended when working indoors. 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 Staple 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 DISCHARGE AREA

DURING USE.

Never place your face, hands or feet closer than 8 inches

(200 mm) from discharge area. A serious injury can result if the

Staples are deflected by the work piece, 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 are too steep of an angle; the Staples can ricochet and

hurt someone.

19. BE CAREFUL OF DOUBLE FIRE DUE TO RECOIL.

If the push lever is unintentionally allowed to recontact the work

piece following recoil, an unwanted fastener will be driven.

In order to avoid this undesirable double fire,

1) Do not push the Stapler on the work piece with strong force;

2) Take the Stapler completely away from the work piece using

recoil, and keep the push lever away from the work piece until

the next desirable shot; and

3) Pull the trigger and release it QUICKLY when performing inter-

mittent operation.

20. DO NOT DRIVE STAPLES INTO THIN BOARDS OR NEAR COR-

NERS AND EDGES OF WORK PIECE.

The Staples can be driven through or away from the work piece

and hit someone.

21. NEVER DRIVE STAPLES FROM BOTH SIDES OF A WALL AT THE

SAME TIME.

The Staples 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.

3) Air hose

• Air hoses should have a minimum of 150 psi (10.4 bar 10.6

kgf/cm2) working pressure rating or 150 percent of the

maximum pressure that could be produced in the air system.

The supply hose should contain a fitting that will provide

"quick disconnecting" from the male plug on the Tool.

4) Hose Coupling

• This tool uses a free-flow connector plug, 1/4 NPT. The

inside diameter should be .200" (5mm) or larger. The fitting

must be capable of discharging tool air pressure when

disconnected from the air supply.

5) Air Consumption

• The model N2503AF requires 3.1 cfm of free air to operate

at the rate of 100 fasteners per minute, at 80 psi. Take the

actual rate at which the tool will be run to determine the

amount of air required. For instance, if your fastener usage

averages 50 fasteners per minute, you need 50% of the

tool’s cfm which is required to operate the tool at 100

fasteners per minute.

6) Operating Pressure

• 70 to 100 psi. Select the operating pressure within this

range for best Staple performance. DO NOT EXCEED THIS

RECOMMENDED OPERATING PRESSURE.

LUBRICATION

Frequent, but not excessive, lubrication is required for best

performance. Oil added through the air line connection will

lubricate the internal parts. Use Air Tool Lubricant, Mobil Velocite

#10, or equivalent. Do not use detergent oil or additives as these

lubricants will cause accelerated wear to the seals and piston

cushion in the Tool, resulting in poor Tool performance and

frequent Tool maintenance.

If no airline lubricator is used, add oil during use into the air

fitting on the Tool once or twice a day. Only a few drops of oil at

a time are necessary. Too much oil will only collect inside the

Tool and will be noticeable in the exhaust cycle.

COLD WEATHER CARE

For cold weather operation, near and below freezing, the

moisture in the air line may freeze and prevent Tool operation.

We recommend the use of WINTER FORMULA Air Tool lubricant

(NEW-MATIC Winter Formula or equivalent) or permanent

anti-freeze (ethylene glycol) as a cold weather lubricant.

CAUTION: Do not store Staplers in a cold weather environment to

prevent frost or ice formation on the Staplers operating valves

and mechanisms that could cause Stapler failure.

NOTE: Some commercial air line drying liquids are harmful to

O-rings and seals – do not use these low temperature air dryers

without checking compatibility.

• Do not operate the Stapler at high pressure without

Staples

CAUTION

WARNING

• Never connect Stapler to pressure which

potentially exceeds 200 psi (13.7 bar 14 kgf/cm2).

• Never use non relieving coupler on Stapler.

2) Filter-Regulator-Lubricator

• A pressure regulator with an operating pressure of

0-125 psi (0-8.6 bar 0-8.8 kgf/cm2) is required to control

the operating pressure for safe operation of this tool. Do not

connect this tool to air pressure which can potentially

exceed 200 psi as tool may fracture or burst, possibly

causing injury.

• 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.

TESTING THE STAPLER

DANGER

• 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 working properly

Manufacturer recommends before each use, check all Screws and

Nuts to make sure they are tight and have not "jarred loose"

from vibration and use. (Shoe, Shoe Base and Pad, Magazine,

Magazine Retainer Bracket, Handle, etc.).

Manufacturer recommends before each use, check the Driver

Blade tip for deformation & breakage to prevent improper driving

of Staples and/or to prevent damage to the Stapler and Flooring.

Before actually beginning the stapling work, test the Stapler by

using the check list below.

STAPLER OPERATION

DANGER

• Operators and others in work

area MUST wear safety glasses

with side shields which

conforms to ANSI Z87.1

specifications.

Read section titled "SAFETY" (pages 4-7)

WARNING

• Keep fingers AWAY from trigger when not driving Staples to avoid

accidental operation.

• Never place your face, hands or feet closer than 8 inches (200 mm)

from discharge area when using. The Stapler may bounce from the

recoil of driving a Staple and an unwanted second Staple may be

driven possibly causing injury.

• Check operation of the safety mechanism frequently. Do not use the

Stapler if the safety is not working correctly as accidental driving of

a Staple may result. Do not interfere with the proper operation of

the safety mechanism.

• Never clamp or tape the trigger or contact trip in an

actuated position.

• Do not drive Staples on top of other Staples or with Stapler at too

steep of an angle; Staples can ricochet and hurt someone.

• Do not drive Staples into thin boards or near corners and edges of

work piece. Staples can be driven through or away from work piece

and hit someone.

• Do not overdrive Staples. NOFMA states that one reason for split

tongues is overdriving.

• Never use Stapler which is defective or operating abnormally.

• Do not use Stapler as a hammer.

• Disconnect air hose from Stapler when:

1) It is not in use;

2) Leaving work area;

3) Moving it to another location; and

4) Handing it to another person.

• Wear safety glasses and safety shoes for protection against foreign

objects.

• Use only Staples from Hitachi.

• Air supply hoses should have a minimum working pressure rating of

150 psi or 150 percent of the maximum pressure produced in the

power source, whichever is higher.

• Check all hoses before connecting to ensure that they are free from

dirt, grit, or particles that could alter the

performance of the Stapler.

• An airline Filter and In-Line Air Regulator adjustable to 125 psi max

are required.

• NEVER use a defective Stapler. Replace worn or damaged parts

immediately. Be sure that the Safety Trigger and

operating mechanisms operate correctly and that all screws and

seals are securely tightened at all times.

• NEVER point Stapler at

yourself or others in work

area.

METHODS OF OPERATION

The Stapler is equipped with the push lever and does not operate

unless the push lever is depressed (upward position).

SEQUENTIAL TRIP SAFETY OPERATION

The model N2503AF Flooring Stapler operates on a sequential

trip system. The sequential trip system requires the operator to

hold the Tool against the work before pulling the trigger. This

makes accurate fastener placement easier. The sequential trip

allows exact fastener location without the possibility of driving a

second fastener on recoil.

SEQUENTIAL TRIP OPERATION:

1) Press the contact trip against the work surface, without

touching the trigger.

THE TOOL MUST NOT CYCLE.

2) Hold the Tool off the work surface and pull the trigger.

THE TOOL MUST NOT CYCLE.

Release the trigger. The trigger must return to the trigger stop on

the frame

3) Pull the trigger and press the contact trip against the work

surface.

THE TOOL MUST NOT CYCLE.

4) With finger off the trigger, press the contact trip against the

work surface. Pull the trigger.

THE TOOL MUST CYCLE.

DUAL TRIGGER OPERATION (PATENT PENDING)

The dual trigger feature gives you multiple options for hand

orientation and trigger actuation to allow you to choose the

actuation method that works best for you for a given application.

The following illustrations are two examples.

WARNING

• Keep your finger off the trigger except during stapling

operation, because serious injury could result if the push

lever accidentally contacts you or others in the work area.

• Keep hands and body away from the discharge area. The

Stapler may bounce from 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 driving operation.

• Exercise caution!

English

13

FASTENER POSITIONING ADJUSTMENT

The fastener position can be adjusted to accommodate 1/4" - 7/16" thicknesses of flooring by way of the adjustment knobs located on

the positioning shoe. The shoe adjustment feature provides close control of the fastener positioning to reduce occurrence of split tongues

or dimples in the flooring surface.

First set the air pressure for consistent drive in the specific work as described on page 11, then use the shoe adjustment knobs to set the

desired position of drive. The fastener should be positioned so that it enters the vertical face of the flooring at the point where the tongue

meets the vertical face.

TO ADJUST THE TOOL TO THE FLOORING:

1. Loosen both Knobs until the Foot and Front Guide move freely.

2. Engage the Nose with the Tongue of Flooring.

3. Push the Front Guide to the subfloor and the Foot to the flooring.

4. Tighten both Knobs.

Note: periodically check the Knobs to ensure that they are tight during use.

**Important: Test the tool on a scrap piece of flooring to ensure proper staple placement and compatibility.

ADJUSTING THE STAPLING DEPTH

Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersized fittings and

hoses or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from receiving an adequate volume of

air, even though the pressure reading is high. The results will be slow operation, jamming, misfeeds or reduced driving power. Before

evaluating tool problems for these symptoms, trace the air supply from the tool to the supply source for restrictive connectors, swivel

fittings, low points containing water and anything else that would prevent full volume flow of air to the tool.
