Some dust created by power sanding, sawing, grinding, drilling, and other construction activities 
contains chemicals known to the State of California to cause cancer, birth defects, or other 
reproductive harm. Some examples of these chemicals are: 

 

-

 lead from lead-based paints, 

 

-

 crystalline silica from bricks and cement and other masonry products, and 

 

-

 arsenic and chromium from chemically-treated lumber. 

 

Your risk from these exposures varies, depending on how often you do this type of work. To 
reduce your exposure to these chemicals: work in a well-ventilated area, and work with approved 
safety equipment, such as dust masks that are specially designed to filter out microscopic 
particles.  

 

Handling the power cord on corded products may expose you to lead, a chemical known to the 
State of California to cause cancer and birth defects or other reproductive harm. Wash hands 
after handling. 

 

 

WORK AREA SAFETY 

 

Inspect the work area before each use. Keep the work area clean, dry, free of clutter, and well lit. 
Cluttered, wet, or dark work areas can result in injury.  

 

Do not use the Concrete Cutter where there is a risk of causing a fire or an explosion; e.g., in the 
presence of flammable liquids, gases, or dust. The cutter can create sparks, which may ignite the 
flammable liquids, gases, or dust. 

 

Do not allow the Concrete Cutter to come into contact with an electrical source. The cutter is not 
insulated and contact will cause electrical shock. 

 

Keep children and bystanders away from the work area while operating the Concrete Cutter. Do 
not allow children to handle the cutter.  

 

Be aware of all power lines, electrical circuits, water pipes, and other mechanical hazards in your 
work area. Some of these hazards may be hidden from your view and may cause personal injury 
and/or property damage if contacted. 

PERSONAL SAFETY 

 

Stay alert, watch what you are doing, and use common sense when operating the Concrete 
Cutter. Do not use the cutter while you are tired or under the influence of drugs, alcohol, or 
medication.  

 

Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing 
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving 
parts. 

 

Use ANSI Z87.1-approved safety goggles or safety glasses with side shields, or when needed, a 
face shield. Use a dust mask in dusty work conditions. Also use non-skid safety shoes, hardhat, 
gloves, dust collection systems, and hearing protection when appropriate. This applies to all 
persons in the work area. 

 

Do not overreach. Keep proper footing and balance at all times. 

 

Remove adjusting keys or wrenches before starting the Concrete Cutter. A wrench or key that is 
left attached to a rotating part of the cutter may cause personal injury. 

 

No smoking, matches, or open flames around machine. Fuel is flammable. 

 

Do not touch hot surfaces.
