5. Air consumption
Using the Air consumption table and the Air
compressor size formula, find a correct compressor
size.

Air consumption
(ltr/cycle)
Air compressor size formula
Amount of air required
=number of Nailers
× average nails driven each minute per Nailer
× air consumption at given air pressure
× safety factor (always 1.2)
Example: 2 Nailers operating at 100 psi driving 30 nails
per minute
Amount of air required
=2 × 30 × .063 (1.8) × 1.2
=4.5 CFM (ft
3
/min) (180 ltr/min)
After making the calculations as shown above, you
should find a compressor providing 4.5 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 70 psi (4.9 bar
2
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.

TESTING THE NAILER
DANGER
WARNING
Never use Nailer unless push lever is operating
properly.
Do not push tool forward when positioning the
first nail in metal hole. If pushing forward, nail
head will be damaged and broken, or will cause
jamming.
This tool has a Sequential Trip Mechanism (Single Shot)
for use when precision nail placement is necessary.
You must first depress the nail point where you
want to drive a nail and then pull the trigger.
After the nail is driven, completely release the
trigger and lift the tool off the work surface.
This tool is not designed for contact trip operation
(bounce fire), and not available for contact trip valve units.
And this tool has a new push lever (safety) mechanism,
this is a different push lever mechanism from another
nailers.
The position of the push lever when the nail feeder is
pulled back is shown as below.
At Non-Firing
Nose
Push Lever
When nails are loaded and the trigger is depressed, the
push lever comes down and when the push lever touches
the workpiece, a nails is driven.

This tool is equipped with a lockout feature that prevents
the tool from being activated when there are 5 or less
nails in the magazine.
English
Operators and others in
work area MUST wear
safety glasses with side
shields which conforms
to ANSI Z87.1
specifications.
