WARNING
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.

Portable Air Tools (ANSI B186.1) and any other applicable safety
codes and regulations.
• For safety, top performance and maximum durability of parts,
operate this tool at 90 psig; 6.2 bar max air pressure with 3/8”
diameter air supply hose.
• Always wear impact resistant eye & face protection (users &
bystanders) when operating or performing maintenance on this
tool.
• Always wear hearing protection when using this tool (users &
bystanders). High sound levels can cause permanent hearing
loss. Use hearing protection as recommended by your employer
or OSHA regulation.
• Keep the tool in efficient operating condition.
• Operators and maintenance personnel must be physically able
to handle the bulk, weight and power of this tool.
• Air powered tools can vibrate during use. Extended exposure
to vibration, repetitive motions or uncomfortable positions
during use may be harmful to your hands and arms. Discontinue
use of tool if discomfort, tingling feeling or pain occurs. Seek
medical advice before resuming use.
• Compressed air can cause severe injury. Never direct air at
yourself or others. Always turn off the air supply, drain hose of
air pressure and detach tool from air supply before installing,
removing or adjusting any part or accessory on this tool, or
before performing any maintenance on this tool. Failure to do so
could result in injury.
• Whip hoses can cause serious injury. Always check for and
replace immediately any damaged, frayed or loose hoses and
fittings.
• Do not point or indulge in any horseplay with this tool.
• Slipping, tripping and/or falling while operating air tools can be
a major cause of serious injury or death. Be aware of excess
hose left on walking or work surface.
• Keep body working stance balanced and firm. Do not overreach
when operating this tool.
• Anticipate and be alert for sudden changes in motion during
use of any power tool.
• Do not carry tool by hose. Protect the hose from sharp objects
and heat.
• Tool shaft may continue to rotate briefly after throttle is
released. Avoid direct contact with accessories during and after
use. Gloves will reduce the risk of cuts or burns.
• Keep away from rotating end of tool. Do not wear jewelry or
loose clothing. Secure long hair. Scalping can occur if hair is not
kept away from tool and accessories. Choking can occur if
neckwear is not kept away from tool and accessories.
• Use only approved replacement parts and accessories
recommended by Cornwell.
• Do not operate a damaged or worn tool. Do no use quick-
detach couplings at tool. See instructions for correct set-up.
• RPM OF THE ACCESSORY MUST EXCEED TOOL RPM. Use
accessories rated at 2,600 RPM or higher.
• Never use grinding wheels, wire brushes, cut-off wheels or
drill bits on this tool.
• Eraser wheels can be mounted providing their speed rating
exceeds the rating of the tool.
• Correct eraser wheel mounting is necessary to prevent injury .
Grip output shaft (or adapter) using supplied wrench and tighten
eraser wheel to prevent spin off when the tool is turned off.
• DO NOT use damaged or excessively worn eraser wheels.
Using damaged or excessively worn eraser wheels will result in
washer (Ref #19) to make contact with work surface resulting in
damage to work or paint. ALWAYS replace excessively worn
eraser wheels with "recommended" eraser wheels.
• Do not lock, tape or wire the “on/off” safety lever in the “on”
position, as the lever must be free to return to the “off” position
when released.
• Do not lubricate tools with flammable or volatile liquids such as
kerosene, diesel or jet fuel.
• Do not force tool beyond its rated capacity.
• Do not remove any labels. Replace damaged labels.
• This tool is not insulated against electric shock.
• Keep tool out of reach of children.
• Note direction of rotation BEFORE operating this tool.
• This tool must not be used in explosive atmospheres.
• Do not use (or modify) the tool for any other purpose than that
for which it was designed without consulting the manufacturer's
authorized representative.
• Servicing and repairs should only be made by an authorized

AIR SUPPLY
Tools operate on a wide range of air pressures. It is recommended
that air pressure measures 90 psig at the tool with the trigger 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. 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 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.
Always turn off the air supply, drain hose of air pressure and detach
tool from air supply before installing, removing or adjusting any part
of accessory on this tool, or before performing any maintenance on
this tool.
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.
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. Grit or gum deposits in the tool may cut power and may be
corrected by cleaning the air strainer and flushing out the tool with
gum solvent oil or an equal mixture of SAE #10 and kerosene. If
outside conditions are in order, disconnect tool from hose and take
tool to your nearest authorized service center.
OPERATION
OPERATION NOTE: Always shut off air supply, drain hose of air
pressure and disconnect tool from air supply when not in use,
before changing accessories or when making repairs.
When using the pin stripe removal tool, be careful not to exert
excessive force.
The burning of the work piece or excessive speed reduction indi-
cates too much force being applied. Changing to a free cutting tool
may be better for the desired rate of speed and stock removal.
Avoid hazardous conditions by making sure there is sufficient force
on the spindle of the cutting tool by placing the spindle 7/16" or
more inside the collet.
The thread size of the shaft (or adapter) must match the size of the
eraser wheel holder.
After mounting a new eraser wheel, start the tool under bench and
run for a few seconds. If the tool starts to vibrate when first fitting
a new eraser wheel or during operation, immediately remove from
service. If tool is dropped, inspect wheel for any damage and if so,
replace the eraser wheel.
When using the tool, be careful not to exert excessive force which
could be hazardous and cause the shaft (or adapter) to bend or
break. The burning if the work piece or excessive speed reduction
indicates too much force being applied
NOTE: During operation, safety goggles must always be worn
to guard against flying rubber (users & bystanders).
