PLEASE REVIEW ALL WARNING INSTRUCTIONS PRIOR TO OPERATION. SAVE THIS MAN U AL FOR FUTURE REF ER ENCE.
AIR SUPPLY
Tools operate on a wide range of air
pres sures. It is recommended that air
pressure mea sures 90 PSI at the tool
with the trigger fully depressed and no
load applied to the tool. Low pressure
(under 90 psig; 6.2 bar) re duc es the
speed of all air tools. Low air pressure
not only wastes time, but also costs
money. Higher pres sure (over 90 psig;
6.2 bar) raises performance beyond the
rated capacity of the tool, which will
short en tool life and could cause injury.
The rec om mend ed hookup pro ce dure
can be viewed in the above figure.
Always use clean, dry air. Dust, corrosive
fumes, and/or water in the air line will
cause damage to the tool. Drain the air
tank daily. Clean the air inlet filter screen
at least once per week.
The air inlet used for connecting the air
supply has standard 1/4" NPT American
Thread. Line pressure should be
increased to compensate for unusually
long air hoses (over 25 feet). Minimum
hose diameter should be 3/8" I.D. Fittings
should have the same inside dimensions
and should be tightly secured.
Ensure an accessible emergency shut
off valve has been installed in the air
supply line and make others aware of its
location.
Lubricate the air motor daily with NAPA
air tool oil. If no air line oiler is used, run
1/2 oz. of oil through the tool. The oil
can be squirted into the tool air inlet or
into the hose at the nearest con nec tion
to the air supply, then run the tool. The
oil plug is only for adding multi-purpose
grease after repair or maintenance of
the impact mechanism. Overfilling will
cause a re duc tion in the power of the
tool.
WARNING:
After an air tool has been
lubricated, oil will discharge through the
exhaust port during the first few seconds
of operation. The exhaust port must be
covered with a towel before applying air
pressure to prevent serious injury.
