After making the calculations as shown above, you
should fi nd a compressor providing 6.1 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.

TESTING THE NAILER

(2.0) (2.3) (2.4)
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.
(1) DISCONNECT AIR HOSE FROM NAILER.
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.
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
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.
DANGER
Operators and others in work
area MUST
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.
REMOVE ALL NAILS FROM NAILER.
ALL SCREWS MUST BE TIGHTENED.
If any screws are loose, tighten them.
