Make sure of the followings 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 Nailer to pressure which potentially
exceeds 200 psi (13.7 bars 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 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 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, find a correct compressor size.
Air consumption table
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
