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.

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.

3. Keep bystanders, children, and visitors away
while operating the tool. Distractions are able
to result in the loss of control of the tool.

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.

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.

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.

4. Do not overreach.

Keep proper footing and balance at all times.

Proper footing and balance enables better
control of the tool in unexpected situations.

5. Use safety equipment.
A dust mask, non-skid safety shoes and
a hard hat must be used for the
applicable conditions.

6. Always wear eye protection.
Wear ANSI-approved safety goggles.

7. Wear heavy-duty work gloves during use.

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.

SAFETYOPERATIONMAINTENANCE SETUP

Air Source

1. Never connect to an air source that is
capable of exceeding 200 psi.

Over pressurizing the tool may cause

SAFETY OPERATION MAINTENANCESETUP

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.

Silicosis and Aluminum Oxide Warnings

WARNING! Abrasive blasting with sand containing

crystalline silica can cause serious or fatal respiratory
disease. Exposure to crystalline silica may cause
silicosis (a serious lung disease), cancer and death.
Exposure to aluminum oxide (a dust generated from
material removing processes) can result in eye, skin
and breathing irritation. Always use a NIOSH (National
Institute for Occupational Safety and Health) approved
respirator and safety goggles. Avoid skin exposure.
Proper ventilation in the work area is required. Read
and understand the 10 recommended measures below
to reduce crystalline silica exposures in the workplace
and prevent silicosis and silicosis related deaths.

NIOSH recommends the following measures to
reduce crystalline silica exposures in the workplace
and prevent silicosis and silicosis-related deaths:

1. Prohibit silica sand (or other substances
containing more than 1% crystalline silica)
as an abrasive blasting material and
substitute less hazardous materials.

2. Conduct air monitoring to measure worker exposures.

3. Use containment methods such as blast-cleaning
machines and cabinets to control the hazard
and protect adjacent workers from exposure.

4. Practice good personal hygiene to avoid
unnecessary exposure to silica dust.

5. Wear washable or disposable protective clothes
at the work site. Shower and change into clean
clothes before leaving the work site to prevent
contamination of cars, homes and other work areas.

6. Use respiratory protection when source controls
cannot keep silica exposures below the NIOSH REL.

7. Provide periodic medical examinations for all
workers who may be exposed to crystalline silica.

8. Post signs to warn workers about the hazard and to
inform them about required protective equipment.

9. Provide workers with training that includes
information about health effects, work practices
and protective equipment for crystalline silica.

10. Report all cases of silicosis to State health
departments and to OSHA or the Mine Safety
and Health Administration (MSHA).

SAFETYOPERATIONMAINTENANCE SETUP

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 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.

SAVE THESE INSTRUCTIONS.

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.

6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.

7. To reduce vibration, maintain
tool as explained in this manual.
If abnormal vibration occurs, stop immediately.
