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 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.
• 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.
• 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.
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY
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 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 and unclean air
will shorten tool 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 1.
The air inlet (Figure 2), 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
3/8" I.D. and fittings should have the same inside dimensions.
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. If
outside conditions are in order, disconnect tool from hose and take
tool to your nearest Matco authorized service center.
LUBRICATION & MAINTENANCE
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 Figure 2, 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.
