19. Check damaged parts. Before further use of the tool, a
guard or other part that is damaged should be carefully checked
to ensure that it will operate properly and perform its intended
function - check for alignment of moving parts, binding of
moving parts, breakage of parts, mounting, and any other
conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced.

medication. A moment of inattentioin while operating power

tools may result in serious personal injury.

23. Make sure tool is disconnected from power supply while
motor is being mounted, connected or reconnected.

24. The dust generated by certain woods and wood products
can be injurious to your health. Always operate machinery in
well ventilated areas and provide for proper dust removal. Use
wood dust collection systems whenever possible.

25. WARNING: Some dust created by power sanding,

sawing, grinding, drilling, and other construction activities

contains chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals
are:

• Lead from lead-base 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.
