3. Avoid unintentional starting. Be sure
the switch is off before connecting to
the air supply. Do not carry the tool with
your finger on the switch or connect the
tool to the air supply with the switch on.
4. Remove adjusting keys and wrenches
before turning the tool on. A wrench or a
key that is left attached to a rotating part of
the tool increases the risk of personal injury.
5. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables better
control of the tool in unexpected situations.
6. Use safety equipment.
A dust mask, non-skid safety
shoes and a hard hat must be
used for the applicable conditions.
7. Always wear eye protection.
Wear ANSI-approved
safety goggles.
8. Always wear hearing protection
when using the tool.
Prolonged exposure to high
intensity noise is able to cause
hearing loss.
Tool Use and Care
1. Use clamps or another practical way
to secure and support the workpiece
to a stable platform. Holding the work
by hand or against the body is unstable
and is able to lead to loss of control.
2. Do not force the tool. Use the correct
tool for the application. The correct tool
will do the job better and safer at the
rate for which the tool is designed.
3. Do not use the tool if the switch does
not turn the tool on or off. Any tool
that cannot be controlled with the switch
is dangerous and must be repaired.
4. Disconnect the tool from the air source
before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce
the risk of starting the tool unintentionally.
Turn off and detach the air supply, safely
discharge any residual air pressure, and
release the throttle and/or turn the switch to
its off position before leaving the work area.
5. Store the tool when it is idle out of reach
of children and other untrained persons.
A tool is dangerous in the
hands of untrained users.
6. Check for misalignment or binding
of moving parts, breakage of parts,
and any other condition that affects
the tool’s operation. If damaged,
have the tool serviced before using.
Many accidents are caused by poorly
maintained tools. There is a risk of
bursting if the tool is damaged.
7. Use only accessories that are identified
by the manufacturer for the specific
tool model. Use of an accessory not
intended for use with the specific tool model,
increases the risk of injury to persons.

SAFETY OPERATION MAINTENANCESETUP
17. Avoid unintentional starting.
Prepare to begin work before
turning on the tool.
18. This product is not a toy.
Keep it out of reach of children.
19. WARNING: Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities, contains chemicals
known [to the State of California] 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
or other masonry products
• 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. (California Health
& Safety Code § 25249.5, et seq.)
20. WARNING: The brass components of this
product contain lead, a chemical known to
the State of California to cause birth defects
(or other reproductive harm). (California
Health & Safety code § 25249.5, et seq.)
21. The warnings, precautions, and instructions
discussed in this instruction manual cannot
cover all possible conditions and situations
that may occur. It must be understood by the
operator that common sense and caution are
factors which cannot be built into this product,
but must be supplied by the operator.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush
or any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the
accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can
dig into the surface of the material causing the
wheel to climb out or kick out. The wheel may
either jump toward or away from the operator,
depending on direction of the wheel’s movement
at the point of pinching. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below.
1. Maintain a firm grip on the power tool
and position your body and arm to allow
you to resist kickback forces. Always
use auxiliary handle, if provided, for
maximum control over kickback or torque
reaction during start-up. The operator
can control torque reactions or kickback
forces, if proper precautions are taken.
2. Never place your hand near the
rotating accessory. Accessory
may kickback over your hand.
3. Do not position your body in the
area where power tool will move if
kickback occurs. Kickback will propel
the tool in direction opposite to the wheel’s
movement at the point of snagging.
4. Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners,
sharp edges or bouncing have a tendency
to snag the rotating accessory and
cause loss of control or kickback.
5. Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades
create frequent kickback and loss of control.
