Contact with or inhalation of dust coming free during use (e.g.
lead-painted surfaces, wood and metal) can endanger your health
and the health of bystanders. Always wear appropriate protective
equipment, such as a dust mask. Always use proper dust
extraction during use.
Wear gloves.

4
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. Adust mask, non-skid safety shoes and a hard hat must be used for
the applicable conditions. Wear heavy-duty work gloves during use.
7. Always wear eye protection. WearANSI-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. 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.
9. Accessories must be rated for at least the speed of the tool marked on the tool label. Wheels
and other accessories running over rated speed can fly apart and result in a risk of injury to
persons.

5
AIR SOURCE
1. Never connect to an air source that 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 rated pressure or within the rated pressure range as marked on the tool.
Always verify prior to using the tool that the air source has been adjusted to the rated air
pressure or within the rated air-pressure range.
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.
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. 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.
VIBRATION PRECAUTIONS
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 of time 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 lowers vibration when there is a choice.
5. Include vibration-free periods each day of work.

6
6. Grip the tool as lightly as possible (while still maintaining a secure hold). Let the tool do
the work.
7. To reduce vibration, maintain tool as explained in this manual. If abnormal vibration
occurs, stop immediately.

Components and Controls
INITIAL SETUP & ASSEMBLY
Air Supply
WARNING: To prevent serious injury from explosion, use only clean, dry, regulated,
compressed air to power this tool. Do not use oxygen, carbon dioxide, combustible gases,
or any other bottled gas as a power source for this tool.
1. Incorporate a filter, regulator with pressure gauge, oiler, in-line shutoff valve, and quick
coupler for best service. Refer to the diagram at the end of this manual for more information.
An in-line shut-off ball valve is an important safety device because it controls the air supply

7
even if the air hose is ruptured. The shut-off valve should be a ball valve because it can be
closed quickly.
Note: if an automatic oiler system is not used, add a few drops of pneumatic tool oil to the
airline connection before operation.Add a few more drops after each hour of continual use.
2. Attach an air hose to the compressor s air outlet. Connect the air hose to the air inlet of the
tool. Other components, such as a coupler plug and quick coupler, will make operation more
efficient, but are not required.
WARNING: To prevent serious injury from accidental operation, do not install a female quick
coupler on the tool. Such a coupler contains an air valve that will allow the air tool to retain
pressure and operate accidentally after the air supply is disconnected.
Note: Air flow, and therefore tool performance, can be hindered by undersized air supply
components. The air hose must be long enough to reach the work area with enough extra
length to allow free movement while working.
3. Turn the tool's On-Off Switch/Speed Control counter-clockwise to the off position; refer to
Operation section for description of controls.
4. Close the in-line shut-off valve between the compressor and the tool.
5. Turn on the air compressor according to the manufacturer s directions and allow it to
build up pressure until it cycles off.
6. Adjust the air compressor s output regulator so that the air output is enough to properly
power the tool, but the output will not exceed the tool s maximum air pressure at any time.
Adjust the pressure gradually, while checking the air output gauge to set the right pressure
range.
7. Inspect the air connections for leaks. Repair any leaks found.
8. If the tool will not be used at this time, turn off and detach the air supply, safely discharge any
residual air pressure, and release the trigger to prevent accidental operation.
Note: Residual air pressure should not be present after the tool is disconnected from the
air supply. However, it is a good safety measure to attempt to discharge the tool in a safe
fashion after disconnecting to ensure that the tool is disconnected and not powered.
WARNING: Read the ENTIRE important operating instructions before set-up or use of this
product.Inspect tool before use, looking for damaged, loose, and missing parts. If any problems
are found, do not use the tool until it has been repaired.
