IMPORTANT SAFETY INSTRUCTIONS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS

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.

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.

WARNING – When using tools, basic precautions

should always be followed, including the following:

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

inuence of drugs, alcohol, or medication.

A moment of inattention while operating the

tool increases the risk of injury to persons.

b. 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.

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 identied by the

manufacturer for the specic tool model. Use of

an accessory not intended for use with the specic tool model, increases the risk of injury to persons.

Service

a. Tool service must be performed only

by qualied 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. 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.

WARNING marking concerning Risk of Explosion.

Specic 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. Do not exceed maximum 90 PSI.

3. Avoid unintentional starting. Prepare to begin work before turning on the tool.

4. Do not leave the tool unattended when it is plugged into a compressor. Release the Trigger, and unplug it from its pneumatic air source before leaving.

5. Never point the Trigger at a human or an animal.

6. Use clamps (not included) or other practical ways to secure and support the workpiece to a stable platform.

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

7. This product is not a toy. Keep it out of reach of children.

8. WARNING: This product, when used for abrasive blasting and similar applications, produces chemicals known to the State of California to cause cancer and birth defects (or other reproductive harm). (California Health & Safety Code § 25249.5, et seq.)

9. WARNING: The brass components of this product contain lead, a chemical known to the State of California to cause birth defects (or other reproductive harm). (California Health & Safety code § 25249.5, et seq.)

10. Obey the manual for the air compressor used to power this tool.

11. Install an in-line shutoff valve to allow immediate control over the air supply in an emergency, even if a hose is ruptured.

12. If any abnormal vibration occurs, stop use immediately.

Silicosis and Aluminum

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.

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.

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.
