Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their compo-
sition 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 inha-
lation 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 sub-
stance known to cause cancer. When cutting such materials, always follow respiratory precautions.
SILICA DUST WARNING
MK-1280 GAS SAW SAFETY
CHECK FOR DAMAGED PARTS
Before using a power tool, check for damaged parts. A guard or any other part that is damaged
should be carefully checked to determine it would operate properly and perform its intended func-
tion. Always check moving parts for proper alignment or binding. Check for broken parts, mountings
and all other conditions that may affect the operation of the power tool. A guard or any damaged part
should be properly repaired or replaced.
DIRECTION OF FEED
Always feed work into a blade or cutter against the direction of rotation. A blade or cutter should
always be installed such that rotation is in the direction of the arrow imprinted on the side of the blade
or cutter.
NEVER STAND ON THE TOOL
Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally contacted.
NEVER LEAVE TOOL RUNNING UNATTENDED – TURN POWER OFF
Do not leave a tool until it comes to a complete stop. Always turn a power tool OFF when leaving the
work area, or, when a cut is finished.
CALIFORNIA PROPOSITION 65 MESSAGE
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con-
tain 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
• 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 those dust masks that are specially designed to filter out microscopic particles.
