Operating Instructions • Warning Information • Parts Breakdown
Air Supply...
Tools of this class operate on a wide range of air pressures.
It is recommended that air pressure of these tools measures
90 PSI at the tool while running free. Higher pressure (over
90 psig; 6.2 bar) raises performance beyond the rated
capacity of the tool, which will shorten tool life because of
faster wear 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
air tank daily. Clean the air inlet filter screen on at least a
weekly schedule. The recommended hookup procedure can
be viewed in the above figure.
The air inlet used for connecting air supply, has standard
1/4" NPT . Line pressure should be increased to compensate
for unusually long air hoses (over 25 feet). Minimum hose
diameter should be 3/8" I.D. and fittings should have the
same inside dimensions and be tightly secured.
Lubrication...
Lubricate the air motor daily with quality air tool oil. If no
air line oiler is used, run a teaspoon of oil through the tool.
The oil can be squirted into the tool air inlet or into the hose
at the nearest connection to the air supply, then run the tool.
The amount of oil to be used is 1 ounce. Overfilling will
cause a reduction in the power of the tool.
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 bit from cutting and cause it to overheat.
Reduce pressure just before bit cuts 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 drill. If the
drill jams in the work, release throttle immediately.
Disconnect the drill before removing bit and determining
cause of trouble. Do not attempt to free the bit by starting
and stopping the motor.
