GENERAL SAFETY RULES

 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-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.

OPERATION

IMPORTANT:Before each use of the bench grinder, inspect its general condition.

Check for loose screws, damaged electrical wiring, cracked, chipped, or damaged

wheels and misalignment or binding of the moving parts. If bench or pedestal

mounted, check that all fasteners are in place and tight.

CAUTION: Keep your bench grinder clean by removing dust from working parts,

the lower portion of the wheel guard assembly, and the work area surrounding the

grinder.
