Working environment
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
