Tools operate on a wide range of air
pres sures. We recommend that air
pressure mea sures 90 PSI at the tool
with the trigger fully depressed and no
load applied to the tool. Low pressure
(less than 90 psig 6.2 bar) re duces the
speed and performance of all air tools.
High pres sure (over 115 psig 8.0 bar)
exceeds the rated capacity of the tool,
which will short en tool life and could
cause injury.
Always use clean, dry air. Dust,
corrosive fumes, and/or water in the
air line will cause damage to the tool.
Drain the water from air lines and
compressor prior to running tool. Clean

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
OPERATION
Locate center of new hole by using
a center punch. Place drill bit tip in
punch mark. Hold drill square with
work and start motor. Apply steady,
even pressure. Do not force. Too
much pressure can cause bit to break
or overheat. Too little pressure will
keep the bit from drilling and cause
it to overheat. Reduce pressure just
before bit goes through the work.
When bit has penetrated work and is
spinning freely, take it from the work
while the motor is running, then turn
off the drill. If the drill jams in the
work, release throttle immediately.
PLEASE REVIEW ALL WARNING INSTRUCTIONS PRIOR TO OPERATION. SAVE THIS MAN U AL FOR FUTURE REF ER ENCE.

Disconnect the drill before removing bit
and determining cause of trouble. Do
not attempt to free the bit by starting
and stopping the motor.
Always turn off the air supply, drain

in water as brittleness and early failure
can result. Accessory breakage or tool
damage may result from prying. Take
smaller bites to avoid getting stuck.
