AIR SUPPLY

DANGER
•
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.
•
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.

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
