AIR SUPPLY
DANGER
●
NEVER use oxygen or other
bottled gases. Explosion may
occur.
WARNING
●
Never connect Nailer to pressure
which potentially exceeds 200 psi
(13.7 bar 14 kgf/cm
2
).
●
Never use non relieving coupler on Nailer.
1. Power source
○
Use only clean, dry, regulated compressed air as a
power source for this Nailer.
○
Air compressors used to supply compressed air to
this Nailer 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 Nailer.
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
2
).
○
Filter-regulator-lubricator units supply an optimum
condition for the Nailer and extend the Nailer life.
These units should always be used.
Filter ............ The fi lter removes moisture and dirt
mixed in compressed air.
Drain daily unless fi tted with an
automatic drain.
Keep the fi lter clean by regular
maintenance.
Regulator ......The regulator controls the operating
pressure for safe operation of the Nailer.
Inspect the regulator before operation to
be sure it operates properly.
Lubricator .... The lubricator supplies an oil mist to the
Nailer.
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, fi nd a correct compressor
size.

Air compressor size formula
Amount of air required
=number of Nailers
× average nails driven each minute per Nailer
× air consumption at given air pressure
× safety factor (always 1.2)
Example: 2 Nailers operating at 100 psi driving 30
nails per minute
Amount of air required
=2 × 30 × .063 (1.8) × 1.2
=4.5 CFM (ft
3
/min) (180 ltr/min)
After making the calculations as shown above, you
should fi nd a compressor providing 4.5 CFM of air
that is required.
LUBRICATION
It is important that the Nailer be properly lubricated.
Without proper lubrication, the Nailer 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 Nailer to malfunction.
