SAFETY WARNINGS
SILICA DUST WARNING:
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 respiratory precautions.
CALIFORNIA PROPOSITION 65 MESSAGE:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain
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
For further information, consult the following sources:
http://www.osha.gov/SLTC/silicacrystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLstA.html
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 lter out microscopic particles.

unnecessary people. Keep all body parts away from the blade and all other moving parts.
• Before starting the machine, check that all guards are in position and correctly tted.
NEVER allow blade exposure from the guard to be more than 180 degrees. DO NOT
operate this machine with any guard removed.
• Inspect the blade, anges and shafts for damage before installing the blade. NEVER use damaged or worn
blade anges.
• The blade shaft anges must be of proper diameter for the size blade being used.
• Inspect the blade, anges and size shown for each blade size. DO NOT exceed maximum blade speed
shown, as excessive speed could result in blade breakage. Use ONLY blades marked with a maximum op-
erating speed greater than the blade shaft speed. Verify speed and saw drive conguration by checking blade
shaft RPM and pulley diameters and blade ange diameters.
• Use the correct blade for the type of work being done. Use only reinforced abrasive blades or steel center
diamond blades and anges supplied with the saw or manufactured for use on concrete saws. DO NOT use
carbide-tipped blades. Check with the blade manufacturer if you do not know if blade is correct.
• Make sure the blade and anges are clean and free of dirt and debris before mounting the blade on the saw.
Verify the blade arbor hole matches the machine spindle before mounting the blade. ALWAYS mount the
blade solidly and rmly. Wrench tighten the arbor nut.

• ALWAYS cut in a straight line. DO NOT cut deeper than 1” per pass with a dry blade. Step cut to
achieve deeper cuts. NEVER cock, jam wedge or twist the blade in a cut. DO NOT grind on the side of
the blade.
• DO NOT touch a dry cutting blade immediately after use.These blades require several
minutes to cool after each cut. DO NOT use a blade that has been overheated (Core has a
bluish color).
• ALWAYS use caution when handling fuel. Shut off the engine and allow to cool before refueling.
• Move the machine at least 10 feet (3 meters) from the fueling point before starting the engine and make
