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 connect-
ing 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.
