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.

• Always operate, inspect and maintain this tool in accordance
with American National Standards Institute Safety Code for
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.
• Place the tool on the work before starting the tool. 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 reciprocate briefly after throttle is
released. Avoid direct contact with accessories during and after
use. Gloves will reduce the risk of cuts or burns.
• Cutting edges and blades can become hot during use. Do not
touch.
• Cutting with these tools will create sharp edges. Wear gloves
to protect hands.
• Keep away from reciprocating 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.
• NEVER OPERATE THIS TOOL WITHOUT REQUIRED BLADE
GUARD IN PLACE.
• Never force the cutting tool to cut faster or through heavier
gauge material than rated capacity.
• 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.
• 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.
• 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
service center.
• Failure to heed these warnings may result in personal injury
and/or property damage.

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.
To properly maintain tool, grease can be applied as needed. To
grease tool remove tap screw (#48) with hex wrench supplied.
Force grease into location using CATMGG2 or similar grease kit.
Recommended grease is high quality synthetic (NLGI grade 2 with
ISO VG 220 base) which has a lithium complex thickener. 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.
Always wear impact-resistant eye and face protection to guard
against flying debris (users & bystanders). Even small projectiles
can injure eyes and cause blindness.
TO INSTALL BLADES
1. Detach tool from air supply.
2. Make sure blade retention area is clean and free from any
metal shavings
3. Rotate blade collar counter clockwise and insert blade until
tang butts against collar
4. Release the collar and the spring loaded lock will clamp
the blade in place
5. Confirm blade is fully inserted by pulling on the blade before use
6. Reattach air supply and begin use
7. Blades that have been in use can be hot so use caution
when handling
TO REMOVE BLADES
1. Rotate collar counter clockwise while pulling on the blade
2. Blades that have been in use can be hot so use caution
when handling
BLADE COLLAR MAINTENANCE
Depending on use and conditions, blade collar clamp area should be
cleaned and lubricated periodically:
1. To Clean: A blow gun can be used in this case. Make
sure eye protection is used to avoid any debris eye
exposure.
2. To Lubricate: Use a dry lubricant (like graphite)
in this case.
NOTE: During operation, safety goggles should always be worn
to guard against flying debris (users & bystanders).
