3. Air hose
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.

Air compressor size formula
Amount of air required
=number of Staplers
× average staples driven each minute
per Stapler
× air consumption at given air
pressure
× safety factor (always 1.2)
Example: 3 Staplers (N5010A) operating
at 100 psi driving 30 staples per
minute
Amount of air required
=3 × 30 × .039 (1.1) × 1.2
=4.2 CFM (ft

/min) (119 ltr/min)
After making the calculations as shown
above, you should find a compressor
providing 4.2 CFM of air that is required.
LUBRICATION
It is important that the Stapler be properly
lubricated.
Without proper lubrication, the Stapler 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 Stapler 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 Stapler
twice a day.
COLD WEATHER CARE
Do not store the Stapler in a cold weather
environment.
Keep the Stapler in a warm area until
beginning the work.
If the Stapler is already cold, bring it in a
warm area and allow the Stapler to warm
up before use.
1 Reduce the air pressure to 64 psi (4.4
bar 4.5 kgf/cm
2 Remove all staples from the Stapler.
3 Connect the air hose and free-fire
(blank-fire) the Stapler.
The lowered air pressure will be
enough to free-fire the Stapler.
Slow speed operation tends to warm
up the moving part.
CAUTION
Do not free-fire the Stapler at high
pressure.
TESTING THE STAPLER
Never use Stapler unless push lever is
operating properly.
Before actually beginning the stapling work,
test the Stapler by using the checklist below.
Conduct the tests in the following order.
If abnormal operation occurs, stop using the
Stapler and contact a Hitachi authorized
service center immediately.

DANGER
Operators and others in
