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.
zAvoid 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.
zRemove adjusting keys and wrenches before turning the tool on. A wrench or key that is left
attached to a rotating part of the tool increases the risk of personal injury.
zDo not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
zUse safety equipment. A dust mask, non-skid safety shoes and a hard hat must be used for
the applicable conditions.
zAlways wear eye protection. Wear ANSI-approved safety goggles.
zAlways wear hearing protection when using the tool. Prolonged exposure to high intensity
noise may result in hearing loss.
zRisk of electric shock. This tool is not provided with an insulated gripping surface.
Contact with a live wire will also make exposed metal parts of the tool live and shock
the operator.
zAvoid body contact with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of electric shock.
zExamine the work piece to avoid contact with hidden wiring. Thoroughly investigate the
work piece for possible hidden wiring before performing work. Contact with live wiring will
shock the operator.
zUse clamps or another practical way to secure and support the work piece to a stable
platform. Holding the work by hand or against the body is unstable and may lead to loss
of control.
zDo not force the tool. Use the correct tool for the job. The correct tool will do the job
better and safer at the rate for which the tool is designed.
zDo not use the tool if the switch does not operate. Any tool that cannot be controlled with
the switch is dangerous and must be repaired.
zDisconnect 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 trigger before leaving the work area.
zStore the tool out of the reach of children and other untrained persons. This tool is
dangerous in the hands of untrained users.
zMaintain 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.
zCheck for misalignment or binding of moving 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.
zUse only accessories that are identified by the manufacturer for the specific tool s
model. Use of an accessory not intended for use with the specific tool model, increases
the risk of injury to persons.
zTool service must be performed only by qualified repair personnel.

5

zWhen servicing a tool, use only identical replacement parts. Use only authorized parts.
Use only the lubricants supplied with the tool or specified by the manufacturer.
zNever 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. 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.
zNever 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.
SPECIFIC SAFETY INSTRUCTIONS
zThe 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.
zOnly use 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.
zAttach all accessories properly to the tool before connecting the air supply.A loose
accessory may detach or break during operation.
zObey the manual for the air compressor used to power this tool.
zInstall an in-line shutoff valve to allow immediate control over the air supply in an emergency,
even if a hose is ruptured.
zUse this tool with both hands only. Using tools with only one hand can result in loss of
control.
zDo 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.

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 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 makeoperation more
efficient, but are notrequired.
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. Release the tool’strigger.
4. Close the in-line shut-off valve between the compressor and thetool.
5. Turn on the air compressor according to the manufacturer’s directions and allow itto build up
pressure until it cyclesoff.

7

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 rightpressure
range.
7. Inspect the air connections for leaks. Repair any leaksfound.
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.
