Warning: The warnings, cautions, and instructions discussed in this instruction manual cannot
cover all possible conditions and situations that may occur. It must be understood by the op-

must be supplied by the operator.
Warning: Some dust created by power/hand 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 chemi-
cals are: A) Lead from lead-based paints, B) Crystalline silica from bricks and cement or
other masonry products, C) 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. (California Health & Safety Code 25249.5,
et seq. )
