Lubrication; Cold Weather Care; Testing The Nailer - Metabo HPT NV 75A5 Manuel D'instructions Et De Sécurité

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 the lubricator before operation
to be sure the supply of lubricant is
adequate.
Use metabo HPT 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

After making the calculations as shown above, you
should fi nd a compressor providing 4.6 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 metabo HPT 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 metabo HPT pneumatic
tool lubricant.
If a lubricator is not available, supply 5 – 10 drops of
metabo HPT 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.
CAUTION
Do not free-fi re the Nailer at high pressure.

TESTING THE NAILER

DANGER
Operators and others in work
area
glasses with side shields
which conforms to ANSI Z87.1
specifi cations.
Ordinary eyeglasses do not
provide adequate protection.
WARNING
Never use Nailer unless push lever is
operating properly.
Before actually beginning the nailing work, test the Nailer
by using the checklist below. Conduct the tests in the
following order.
