W A R N I N G (PROPOSITION 65)
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-based paints
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically treated lumber.
Your risk of exposure to these chemicals 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 dust masks that are specially designed to lter out microscopic
particles.

operator. Avoid cutting in the dangerous area shown in gure 11.
• Use the tip of string to do the cutting; do not force string head into uncut grass.
• Wire and picket fences cause extra string wear and breakage. Stone and brick walls, curbs,
and wood may wear string rapidly.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be
damaged by the string.
