the presence of flammable liquids, gases, or dust. Pneumatic equipment can create sparkswhich may ignite flammables.

Keep bystanders, children, and visitors away while operating a pneumatic

tool. Distractions can cause you to lose control. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed.

PERSONAL SAFETY

ALSO SEE SPECIFIC SAFETY RULES ON PAGE 4.

Stay alert. Watch what you are doing, and use common sense when operating a pneumatic tool. Do not use a pneumatic tool while tired or under

the influence of drugs, alcohol, or medication. A moment of inattention while operating pneumatic tools may result in serious personal injury.

Dress properly. Do not wear loose clothing or jewelry. Contain long hair.

Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. Always wear ANSI approved safety glasses and full face shield. Always wear hearing protection.

Avoid accidental starting. Be sure the Trigger (42) is off before connect-

ing to the air supply. Carrying pneumatic tools with your hand on the Trigger, or connecting pneumatic tools to the air supply with the Trigger on, invites accidents.

Remove adjusting keys or wrenches before turning on the tool. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

TOOL USE AND CARE

Use clamps or other practical ways to secure and support the workpiece to

a stable platform. Always wear sandblasting gloves. Never point the Nozzle of the Sandblaster Gun at your gloves. Holding the work by hand is unstable and may lead to loss of control and injury. Only work on a workpiece that is properly secured.

Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

3.

Do not use this tool if the Trigger does not turn it on or off. Any tool that cannot be controlled with the Trigger is dangerous and must be replaced.

Disconnect the grit supply hose from the tool before making any adjust-

ments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

Maintain tools with care. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.

Check for misalignment or binding of moving parts, breakage of parts,

damaged air hose (not included), and any other condition that may affect the

tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the manufacturer for your

model. Accessories that may be suitable for one tool may become hazardous when used on another tool.

SERVICE

Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts. Follow instructions in the “Inspection, Maintenance, And Cleaning” section of this

manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of injury.

SPECIFIC SAFETY RULES

Maintain labels and nameplates on the Sandblaster Gun. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

Use clean, dry, regulated, compressed air from the air compressor to the

sandblaster. Never use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.

Always disconnect the Sandblaster Gun from its grit supply hose source, and squeeze the Trigger (42), while pointing unit in a safe direction, to release all compressed air and grit in the tool before performing any maintenance or services.

8.

Maintain a firm grip on the Sandblaster Gun when in use.

Never point the Sandblaster Gun toward yourself, other people, or animals.

Keep all people and animals safely away from the work area.

Maintain a safe distance away from the object being sandblasted. Whenever possible, sandblast the object at a 45 degree angle to minimize the possibility of grit, dirt, and debris ricocheting directly backward toward your face and body.

Whenever possible, perform a sandblasting test on a small area of the

object to be sandblasted. If necessary adjust the distance to the object and/or the Nozzle (37) to be used for more effective results.

Avoid unintensional starting. Make sure the Trigger (42) on the Sandblaster

Gun is in its “OFF” or “CLOSED” position when the tool is not in use.

9.

Make sure to read and understand all safety warnings and precautions as outlined in the manufacturer’s owner’s manual of the sandblaster unit with which you will use the Sandblaster Gun.

10.

Industrial applications must follow OSHA requirements.

11. WARNING! Abrasive blasting with sand containing crystalline silica

can cause serious or fatal respiratory disease. Exposure to cystalline 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, safety goggles, and a full face shield. Avoid skin exposure. Proper ventilation in the work area is required.

Read and understand the ten recommended measures below to reduce crystalline silica exposure 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:

A. Prohibit silica sand (or other substances containing more than 1% crystalline

silica) as an abrasive blasting material and substitute less hazardous

materials.

B. Conduct air monitoring to measure worker exposures, (if using under OSHA

applications).

C.

Use containment methods such as blast-cleaning machines and cabinets to

SKU 92189 For technical questions, please call 1-800-444-3353 PAGE 5

control the hazard and protect adjacent workers from exposure.

D. Practice good personal hygiene to avoid unecessary exposure to silica dust.

E. Wear washable or disposable protective clothes at the worksite. Shower, and

change into clean clothes before leaving the worksite to prevent contamina-

tion of cars, homes, and other work areas.

F. Use respiratory protection when source controls cannot keep silica exposures

below the NIOSH recommended levels.

G. Provide periodic medical examinations for all workers who may be exposed

to crystalline silica.

H. Post signs to warn workers about the hazard and to inform them about re-

quired protective equipment.

I. Provide workers with training that includes information about health effects,

work practices, and protective equipment for crystalline silica.

J. Report all cases of silicosis to State health departments and to OSHA or the

Mine Safety and Health Administration (MSHA).
