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 ap-
plicable 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 main-
tenance 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.
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY.
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.
• 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.
• Correct grinding wheel mounting is
necessary to prevent injury from broken
wheels. Do not use chipped or cracked
grinding wheels. Grinding wheels should
be a free fit on the spindle to prevent stress
at the hole. Use only wheel collars that
come with the grinder for mounting the
grinding wheel. Flat washers or other
adapters may over stress the wheel. Always
use heavy paper blotter discs between the
wheel collars and the grinding wheel.
Tighten the wheel on the spindle to prevent
spin off when the air grinder is turned off.
• 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.

Operating Instructions • Warning Information • Parts Breakdown
Lubrication...
Lubricate the air motor daily with quality 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 or into the hose
at the nearest connection to the air supply, then run the tool.
Air Supply...
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 (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.
Operation...
When using the grinder be careful not to exert excessive
force. Too much force could be hazardous if it causes the
cutting tool spindle to bend or break.
The burning of the work piece or excessive speed reduction
indicates 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.
Air Inlet
Warranty...
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.
