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, combustible gases or any other
bottled gases.
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 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. Hose coupling
The Nailer can be installed as follows:
Remove the dust seal 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 Nailer when disconnected.
Never use a non relieving coupler on the Nailer.
