BEFORE OPERATION

Read section titled "SAFETY" (pages 4 – 8).
Make sure of the followings before operation.

WORKING ENVIRONMENT

● No fl ammable gas, liquid or other
fl ammable objects at worksite.
● Clear the area of children or
unauthorized personnel.

AIR SUPPLY

● NEVER use reactive
● Never connect Nailer to pressure
which potentially exceeds 200 psi
(13.7 bar 14 kgf/cm
fails.
● 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
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
○ Filter-regulator-lubricator

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
Compressed air supply hoses shall have
a minimum working pressure rating equal
to or greater than the pressure from the
power source if a regulator fails, or 150
psi (10.4 bar 10.6 kgf/cm
greater.
4. Air consumption
Using the Air consumption table and the
Air compressor size formula, fi nd a correct
compressor size.
