3.Air hose

Air hose must have a minimum working pressure rating of 150 psi (10.4 bar 10.6 kgf/ cm2) 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 Nailers

⋅average nails driven each minute per Nailer

⋅air consumption at given air pressure

⋅safety factor (always 1.2)

Example: 3 Nailers (NT50AE2 (S) or NT32AE2 (S)) operating at 100 psi driving 30 nails per minute

Amount of air required

=3 ⋅ 30 ⋅ .025 (.73) ⋅ 1.2

=2.7 CFM (ft3/min) (78.8 ltr/min)

After making the calculations as shown above, you should find a compressor providing 2.7 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.
