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. 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 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 neck-
wear is not kept away from tool and
accessories.
•Drill bits can bind suddenly and cause rotation of the
work piece or tool, causing injury to arms and/or
shoulders. Enough torque is generated to cause falls.
Always use sharp bits. Use less downward pressure at
breakthrough.
•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.
•Use accessories recommended by Matco Tools.

Operation...
Locate center of new hole by using a center punch.
Place drill bit tip in punch mark. Hold drill square with
work and start motor. Apply steady, even pressure. Do
not force. Too much pressure can cause bit to break or
overheat. Too little pressure will keep bit from cutting
and cause it to overheat. Reduce pressure just before
bit cuts through the work. When bit has penetrated
work and is spinning freely, take it from the work while
the motor is running, then turn off drill. If the drill jams
in the work, release throttle immediately. Disconnect the
drill before removing bit and determining cause of trou-
ble. Do not attempt to free the bit by starting and
stopping the motor.
MATCO TOOLS™ 1 YEAR LIMITED
WARRANTY 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.
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 the tool’s 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.
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.
The amount of oil
to be used is 1 ounce.
Overfilling will cause
a reduction in the
power of the tool.
