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 consumption
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 (N3804AB2) operating at 100 psi driving 30 staples per minute
Amount of air required
=3 × 30 × .027 (.78) × 1.2
=3.0 CFM (ft
3
/min) (84 ltr/min)
After making the calculations as shown above, you should find a compressor providing
3.0 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 40 psi (2.8 bar 2.8 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.
