Lubrication; Cold Weather Care; Testing The Nailer - Hitachi NR 83A5 Manuel D'instructions

Lubricator .... The lubricator supplies an oil mist to the
Nailer.
Inspect the lubricator before 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,

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
100
moving part.
