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.

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.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power of 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, disconnect tool from hose
and take tool to your nearest Cornwell Tools authorized service
center.
LUBRICATION & MAINTENANCE
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.
WARRANTY
Cornwell Tools 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 Tools
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 Tool's sole liability under this or any implied warranty and under no circumstances shall Cornwell Tools 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.
