Lubrication; Cold Weather Care; Testing The Nailer - Hitachi NP 50A Manuel D'instructions Et De Sécurité

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

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.
CAUTION
● Do not free-fi re the Nailer at high pressure.
