WARNING
Some dust created by power sanding, saw-
ing, grinding, drilling, and other construc-
tion 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 those dust masks that are specially
designed to filter out microscopic particles.
The ECHO model CSG-7410 Engine Cut-off saw is
a high-performance gasoline-powered tool de-
signed for use with a recommended 350 x 4.7 x 20

Use only ECHO’s wheels or other wheels having
