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
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
2
kgf/cm
) 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.

After making the calculations as shown
above, you should find a compressor
providing 3.3 CFM of air that is required.
LUBRICATION
It is important that the Nailer be properly
lubricated.
Without proper lubrication, the Nailer will not
work properly and parts will wear
prematurely.
Use Hitachi pneumatic tool lubricant.
Do not use detergent oil or additives.
These lubricants will harm the O-rings
and other rubber parts. This will cause
the Nailer to malfunction.
Filter-regulator-lubricator units should
always be used.
Keep the lubricator filled with Hitachi
pneumatic tool lubricant.
If a lubricator is not available, supply 5 –
10 drops of Hitachi pneumatic tool
lubricant into the air plug on the Nailer
twice a day.
COLD WEATHER CARE
Do not store the Nailer in a cold weather
environment.
Keep the Nailer in a warm area until
beginning the work.
If the Nailer is already cold, bring it in a
warm area and allow the Nailer to warm
up before use.
1 Reduce the air pressure to 64 psi (4.4
bar
4.5 kgf/cm
2 Remove all nails from the Nailer.
3 Connect the air hose and free-fire
(blank-fire) the Nailer.
The lowered air pressure will be
enough to free-fire the Nailer.
Slow speed operation tends to warm
up the moving part.
CAUTION
Do not free-fire the Nailer at high
pressure.
