Make sure of the followings before operation.
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 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
⅜ Use only clean, dry, regulated
compressed air as a power source for
this Nailer.
⅜ 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”.
⅜ Moisture or oil in the air compressor may
accelerate wear and corrosion in the
Nailer.
Drain daily.
2. Filter-Regulator-Lubricator
⅜ Use a regulator with a pressure range of
0 – 120 psi (0 – 8.3 bar 0 – 8.5 kgf/cm
2
).
⅜ 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
⅜ 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, find a
correct compressor size.
