PROPOSITION 65 wARNING  
Engine exhaust and some of  
its constituents, and some dust created  
by power sanding, sawing, grinding,  
drillingandotherconstructionactivities  
contains chemicals known to the State  
of California to cause cancer, birth  
defects and other reproductive harm.  
Some examples of these chemicals are:  
Leadfromlead-basedpaints.  
Crystallinesilicafrombricks.  
Cementandothermasonryproducts.  
Arsenicandchromiumfromchemically  
treatedlumber.  
Your risk from these exposures varies,  
dependingonhowoftenyoudothistype  
of work. To reduce your exposure to  
these chemicals: ALWAYS 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.

SILICOSIS/RESPIRATORY wARNINGS  
WARNING WARNING  
SILICOSIS WARNING  
RESPIRATORY HAZARDS  
Grinding/cutting/drilling of masonry, concrete, metal and  
other materials with silica in their composition may give  
off dust or mists containing crystalline silica. Silica is a  
basic component of sand, quartz, brick clay, granite and  
numerous other minerals and rocks. Repeated and/or  
substantial inhalation of airborne crystalline silica can  
cause serious or fatal respiratory diseases, including  
silicosis. In addition, California and some other  
authorities have listed respirable crystalline silica as a  
substance known to cause cancer. When cutting such  
materials, always follow the respiratory precautions  
mentioned above.  
Grinding/cutting/drilling of masonry, concrete, metal and  
other materials can generate dust, mists and fumes  
containing chemicals known to cause serious or fatal  
injury or illness, such as respiratory disease, cancer,  
birth defects or other reproductive harm. If you are  
unfamiliar with the risks associated with the particular  
process and/or material being cut or the composition of  
the tool being used, review the material safety data  
sheet and/or consult your employer, the material  
manufacturer/supplier, governmental agencies such as  
OSHA and NIOSH and other sources on hazardous  
materials. California and some other authorities, for  
instance, have published lists of substances known to  
cause cancer, reproductive toxicity, or other harmful  
effects.  
Control dust, mist and fumes at the source where  
possible. In this regard use good work practices and  
follow the recommendations of the manufacturers or  
suppliers, OSHA/NIOSH, and occupational and trade  
associations. Water should be used for dust  
suppression when wet cutting is feasible. When the  
hazards from inhalation of dust, mists and fumes cannot  
be eliminated, the operator and any bystanders should  
always wear a respirator approved by NIOSH/MSHA for  
the materials being used.
