WARNING
●
Never connect Nailer to pressure which
potentially exceeds 200 psi (13.7 bar 14 kgf/cm
2
)
if a regulator fails.
●
Never use non relieving coupler on
Nailer.
1. Power source
○
Use only clean, dry, regulated compressed air as a
power source for this Nailer.
○
Air compressors used to supply compressed air to
this Nailer must comply with the requirements of
the latest version of ANSI Standard B 19.3 “Safety
Standard For Compressors For Process Industries”.
○
Moisture or oil in the air compressor may accelerate
wear and corrosion in the Nailer.
Drain daily.
2. Filter-Regulator-Lubricator
○
Use a regulator with a pressure range of 0 – 120 psi
(0 – 8.3 bar 0 – 8.5 kgf/cm
2
).
○
Filter-regulator-lubricator units supply an optimum
condition for the Nailer and extend the Nailer life.
These units should always be used.
Filter ........ The fi lter removes moisture and dirt mixed
in compressed air.
Drain daily unless fi tted with an automatic
drain.
Keep the fi lter clean by regular
maintenance.
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.

3. Air hose
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 150 psi (10.4 bar 10.6 kgf/cm
2
), whichever is
greater.
4. Air consumption
Using the Air consumption table and the Air
compressor size formula, fi nd a correct compressor
size.

Air compressor size formula
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 operating at 100 psi driving 30
nails per minute
Amount of air required
= 2 × 30 × .088 (2.5) × 1.2
= 6.3 CFM (ft
3
/min) (180 ltr/min)
After making the calculations as shown above, you
should fi nd a compressor providing 6.3 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.
