Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
• leadfromlead-basedpaints,
• crystallinesilicafrombricksandcementandothermasonry
products, and
• arsenicandchromiumfromchemically-treatedlumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.

TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic action.
Reduced compressor output, excessive drain on the air line, moisture or
restrictions in air pipes or the use of hose connections of improper size or poor
conditions may reduce air supply. If outside conditions are in order, and the
tool still performs erratically, disconnect tool from hose and take tool to your
nearest Cornwell authorized service center.
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.

AIR SUPPLY
Tools of this class operate on a wide range of air pressures.
It is recommended that air pressure measures 90 psig at the tool with the trig-
ger fully depressed and no load applied to the tool. Higher pressure (over 90
psig; 6.2 bar) raises performance beyond the rated capacity of the tool, which
will shorten 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 water from air lines and compressor prior to
running tool daily. Clean the air inlet filter screen weekly. 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 pres-
sure 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. Ensure an accessible emer-
gency shut off valve has been installed in the air supply line and make others
aware of its location.
Ensure an accessible emergency shut off valve has been installed in the air
supply line and make others aware of its location.
LUBRICATION
Lubricate the air motor daily with high quality 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 connection to the air supply, then run the
tool. A rust inhibitive oil is acceptable for air tools.
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.
