WARNING
Never connect Stapler to pressure which
potentially exceeds 200 psi (13.7 bar
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
Use a regulator with a pressure range of 0 – 120 psi (0
– 8.3 bar 0 – 8.5 kgf/cm
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 hose must have a minimum working pressure
rating of 150 psi (10.4 bar 10.6 kgf/cm
maximum pressure produced in the system, whichever
is higher.
4. Hose coupling
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.

).
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.
5. Air consumption
Using the Air consumption table and the Air
compressor size formula, find a correct compressor
size.
Air consumption table
Operating pressure
Air consumption
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 (N5008AC) operating at 100 psi
driving 30 staples per minute
Amount of air required
=3 × 30 × .040 (1.1) × 1.2
=4.3 CFM (ft
3
/min) (119 ltr/min)
After making the calculations as shown above, you
should find a compressor providing 4.3 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.
