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:

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.

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.
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.
LUBRICATION
Lubricate the air motor daily with 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.
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.
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.
WARRANTY
Cornwell warrants its air tools for a period of 1 year to the consumer. We will repair any air tool covered under this warranty which proves
to be defective in material or workmanship during the warranty period. In order to have your tool repaired, return the tool to any Cornwell
Authorized Warranty Center, freight prepaid. Please include a copy of your proof of purchase and a brief description of the problem. The
tool will be inspected and if any part or parts are found to be defective in material or workmanship, they will be repaired free of charge
and the repaired tool will be returned to you freight prepaid.
This warranty gives you specific rights. You may also have other rights which vary from state to state.
The foregoing obligation is Cornwell’s sole liability under this or any implied warranty and under no circumstances shall Cornwell be liable
for any incidental or consequential damages.
Note: Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion
may not apply to you.
