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: 2 Nailers (NV83A2) operating at 100 psi
driving 30 nails per minute
Amount of air required
=2 × 30 × .084 (2.4) × 1.2

After making the calculations as shown above, you
should fi nd a compressor providing 6.0 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.

● 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.
If abnormal operation occurs, stop using the Nailer
and contact a metabo HPT authorized service center
immediately.
