Lubrication; Cold Weather Care - Hitachi NP 35A Instruction And Safety Manual

1. Power source
○ Use only clean, dry, regulated compressed air as a
power source for this Nailer.
○ Air compressors used to supply compressed air to this
Nailer must comply with the requirements of the latest
version of ANSI Standard B 19.3 "Safety Standard For
Compressors For Process Industries".
○ Moisture or oil in the air compressor may accelerate
wear and corrosion in the Nailer.
Drain daily.
2. Filter-Regulator-Lubricator
○ Use a regulator with a pressure range of 0 – 100 psi
(0 – 6.9 bar 0 – 7 kgf/cm
○ Filter-regulator-lubricator units supply an optimum
condition for the Nailer and extend the Nailer life.
These units should always be used.
Filter ................ The fi lter removes moisture and dirt
mixed in compressed air.
Drain daily unless fi tted with an
automatic drain.
Keep the fi lter clean by regular
maintenance.
Regulator ......... The regulator controls the operating
pressure for safe operation of the
Nailer.
Inspect the regulator before operation
to be sure it operates properly.
Lubricator ........ The lubricator supplies an oil mist to
the Nailer.
Inspect
operation to be sure the supply of
lubricant is adequate.
Use Hitachi pneumatic tool lubricant.

Compressed air supply hoses shall have a minimum
working pressure rating equal to or greater than the
pressure from the power source if a regulator fails, or

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 operating at 100 psi driving 30
nails per minute
Amount of air required
= 3 × 30 × .018 (.5) × 1.2
= 1.9 CFM (ft /min) (94 ltr/min)

After making the calculations as shown above, you
should fi nd a compressor providing 1.9 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 fi lled 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-fi re (blank-fi re) the
Nailer.
The lowered air pressure will be enough to free-
fi re the Nailer.
Slow speed operation tends to warm up the
moving part.
