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 psi; 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 & mAINTENANcE
Lubricate the air motor daily with quality air tool oil. If no air line oiler is
used, run 1/2 oz. of air tool 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.
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.
