Safety Alert Symbol
and Signal Words
In this manual, on the labeling, and all other
information provided with this product:
This is the safety alert symbol. It is
used to alert you to potential personal
injury hazards. Obey all safety
messages that follow this symbol
to avoid possible injury or death.
DANGER indicates a hazardous situation which, if
not avoided, will result in death or serious injury.
Work Area
a. Keep the work area clean and well lighted.
Cluttered benches and dark areas increase the
risks of electric shock, re, and injury to persons.
b. Do not operate the tool in explosive atmospheres,
such as in the presence of ammable liquids,
gases, or dust. The tool is able to create sparks
resulting in the ignition of the dust or fumes.
c. 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
a. 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
inuence of drugs, alcohol, or medication.
A moment of inattention while operating the
tool increases the risk of injury to persons.

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.
WARNING indicates a hazardous situation which, if
not avoided, could result in death or serious injury.
CAUTION, used with the safety alert symbol,
indicates a hazardous situation which, if not
avoided, could result in minor or moderate injury.
NOTICE is used to address practices
not related to personal injury.
CAUTION, without the safety alert symbol, is used
to address practices not related to personal injury.
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:
c. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables better
control of the tool in unexpected situations.
d. Use safety equipment. A dust mask,
non-skid safety shoes and a hard hat
must be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
e. Always wear eye protection.
Wear ANSI-approved safety goggles.
f. Always wear hearing protection when
using the tool. Prolonged exposure to
high intensity noise is able to cause
hearing loss.
Tool Use and Care
a. 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.
b. 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.
c. 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.

d. 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.
e. Use only accessories that are identied by the
manufacturer for the specic tool model. Use of
an accessory not intended for use with the specic
tool model, increases the risk of injury to persons.
Service
a. Tool service must be performed only
by qualied repair personnel.
b. When servicing a tool, use only identical
replacement parts. Use only authorized parts.
Air Source
a. 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.
b. WARNING! Do not exceed 100 PSI
working air pressure during use.
c. 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.

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.
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)
11. 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.
SAVE THESE
INSTRUCTIONS.
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.
