IMPORTANT SAFETY INSTRUCTIONS
INSTRUCTIONS PERTAINING TO A RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS
WARNING – When using tools, basic precautions should always be followed, including the following:
General
To reduce the risks of electric shock, fire, and injury to persons,
read all the instructions before using the tool.
Work Area
1. Keep the work area clean and well lighted.
Cluttered benches and dark areas increase the
risks of electric shock, fire, and injury to persons.
3. Keep bystanders, children, and visitors away
while operating the tool. Distractions are
able to result in the loss of control of the tool.
2. Do not operate the tool in explosive
atmospheres, such as in the presence
of flammable liquids, gases, or dust.
The tool is able to create sparks resulting
in the ignition of the dust or fumes.

Personal Safety
1. Stay alert. Watch what you are doing and
use common sense when operating the tool.
Do not use the tool while tired or under the
influence of drugs, alcohol, or medication.
A moment of inattention while operating the
tool increases the risk of injury to persons.
2. Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep hair, clothing, and gloves away from
moving parts. Loose clothes, jewelry, or long
hair increases the risk of injury to persons as
a result of being caught in moving parts.
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.
SAFETYOPERATIONMAINTENANCE SETUP
8. Always wear hearing protection
when using the tool.
Prolonged exposure to high intensity
noise is able to cause hearing loss.
9. Risk of Electric Shock. This tool is not
provided with an insulated gripping surface.

metalpartsofthetool″live″andshocktheoperator.
10. Avoid body contact with
grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased
risk of electric shock if your body is grounded.
11. Explore the workpiece to avoid contact
with hidden wiring. Thoroughly investigate
the workpiece for possible hidden wiring
before performing work. Contact with
live wiring will shock the operator.
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. Maintain the tool with care. Keep a cutting
tool sharp and clean. A properly maintained
tool, with sharp cutting edges reduces the
risk of binding and is easier to control.
7. 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.
8. 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.

is capable of exceeding 200 psi.
Over pressurizing the tool may cause
bursting, abnormal operation, breakage
of the tool or serious injury to persons.
Use only clean, dry, regulated compressed air at the

tool or specified by the manufacturer.
2. Never use oxygen, carbon dioxide, combustible
gases or any bottled gas as an air source
for the tool. Such gases are capable of
explosion and serious injury to persons.
Symbols and Specific Safety Instructions
Specific Safety Instructions
1. The warnings and precautions discussed in this
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.
2. Only use with accessories rated to handle the
forces exerted by this tool during operation.
Other accessories not designed for the forces
generated may break and forcefully launch pieces.
3. Attach all accessories properly to the tool before
connecting the air supply. A loose accessory
may detach or break during operation.
4. Obey the manual for the air compressor
used to power this tool.
5. Install an in-line shutoff valve to allow
immediate control over the air supply in an
emergency, even if a hose is ruptured.
6. Use this tool with both hands only. Using tools
with only one hand can result in loss of control.
7. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.
This tool vibrates during use. Repeated or
long-term exposure to vibration may cause
temporary or permanent physical injury,
particularly to the hands, arms and shoulders. To
reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for
an extended period should first be examined
by a doctor and then have regular medical
check-ups to ensure medical problems are not
being caused or worsened from use. Pregnant
women or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or Raynaud's
Disease should not use this tool. If you feel
any symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each day of work.
Page 4 For technical questions, please call 1-888-866-5797. Item 67474
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
SAVE THESE INSTRUCTIONS.
