WARNING
No fl ammable gas, liquid or other ●
fl ammable 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 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: 3 Nailers operating at 100 psi
driving 30 nails per minute
Amount of air required
= 3 × 30 × .045 (1.29) × 1.2
= 4.9 CFM (ft
