BEFORE OPERATION

Read section titled "SAFETY" (pages 4 –
6).
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 connect Nailer to pressure
which potentially exceeds 200 psi
(13.7 bar 14 kgf/cm
● 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 –
100 psi (0 – 6.9 bar 0 – 7 kgf/cm
○ 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.
WARNING
DANGER
● Never use oxygen
or other bottled
gases. Explosion
may occur.

Drain daily unless fi tted with an automatic
drain.
Keep the fi lter
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 ) or 150% of the maximum pressure
2
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.
