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
LUBRICATION
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

Always use clean, dry air. Dust, corro-

will cause damage to the tool. Drain the
air tank daily. Clean the air inlet filter
screen at least once per week.
