SPECIFICATIONS
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.

This Instruction Manual Contains Important Safety
Information.
Read THIS INSTRUCTION
MANUAL Carefully and understand
ALL INFORMATION Before
Operating THIS Tool.
• Always operate, inspect and
maintain this tool in accordance with
American National Standards Institute Safety
Code of 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
and face protection when operating
or performing maintenance on
this tool. Always wear hearing
protection when using this tool.
• 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 under pressure 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
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
damaged, frayed or loose hoses
and fittings, and replace immediately. Do
not use quick detach couplings at tool. See
instructions for correct set-up.
• Air powered tools can vibrate in
use. Vibration, repetitive motions
or uncomfortable positions over
extended periods of time 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.
• Place the tool on the work before
starting the 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 the walking or work surface.
• Keep body working stance balanced and firm.
Do not overreach when operating the tool.
• Anticipate and be alert for sudden changes in
motion during start up and operation of any
power tool.
• Do not carry tool by the hose.
Protect the hose from sharp objects
and heat.
• Cutting with these tools will create sharp
edges. Wear gloves to protect hands.
• Avoid direct contact with accessory and work
surface during and after work.
• Cutting edges can become hot during use. Do
not touch.
• Never force the tool to cut faster or through
heavier gauge material than rated capacity.
• Do not lubricate tools with flammable or volatile
liquids such as kerosene, diesel or
jet fuel.
• Don’t force tool beyond its rated capacity.
• Do not remove any labels. Replace any
damaged labels.

RL838 2/27/02
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools measure 90 PSI at the
tool while running free. Higher pressure and unclean air will shorten
the toolʼs life because of faster wear and may create a hazardous
condition.
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 hook-up procedure can be viewed in Figure 2.
The air inlet (Figure 1), used for connecting air supply, has standard
1/4" NPT American Thread.
Line pressure should be increased to compensate for unusually long air
hoses (over 25 feet). Minimum hose diameter should be 1/4" I.D. and
fittings should have the same inside dimensions.
AIR SUPPLY
TROUBLESHOOTING
LUBRICATION & MAINTENANCE
WARRANTY
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,
disconnect tool from hose and
take tool to your nearest Matco authorized
service center.
Lubricate the tool daily with a good grade of air tool oil. If no air
line oiler is used, run a teaspoon of oil through the tool. The oil can
be squirted into the tool air inlet (A) Figure 1, 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.
Matco 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 Matco
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 Matco's sole liability under this or any
implied warranty and under no circumstances shall Matco 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.
