Dry cutting/grinding accessories are air cooled. This means that after every cut the
accessoryshouldberun„free”(noload)forafewsecondstoallowtheairflow
around the accessory to cool it and dissipate the built up heat.
Operator Safety
These warnings apply to the accessories. Always read and follow the operator’s ma-
nual supplied with your tool. Only use the accessories that the tool manufacturer re-
commends. Failure to follow these warnings and the information in the tool operator’s
manual can result in serious injury or death.
Warning!
Comply with ANSI B7.1 Failure to comply could result in bodily injury.
ANSI
refers to the American National Standards Institute, Inc. 1430 Broadway, New York,
NY 10018 who have published B7.11983 „safety requirements for the use, care and
protection of abrasive wheels”.

WARNING:
Some dust created by grinding, sanding, cutting and drilling contains che-
micals known to cause cancer, birth defects or other reproductive harm; or serious
and permanent respiratory or other injury. Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks, concrete and other masonry products, and natural
stone
• 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 exposure to these chemicals, the operator and bystanders should:
• Work in a well-ventilated area
• Work with approved safety equipment, such as respiratory protection appropriate for
thetypeofdustgenerated,anddesignedtofilteroutmicroscopicparticles
• Direct dust away from face and body
Avoid prolonged contact with dust. Wear protective clothing and wash exposed areas
with soap and water.
Allowing dust to get into your mouth, eyes, or to remain on your
skin may promote absorption of harmful chemicals.
Diamond Blade/Wheels – Performance Factors
Select the proper blade/wheel for the application. Use a general purpose (medium)
blade/wheel for a variety of cutting/grinding brick and block, a blade for hard base
materials for cutting/grinding granite, marble and pavers, a blade/wheel for soft ab-
rasive base materials for cutting grinding limestone, lightweight block and asphalt.
Make sure that the diamond blade/wheel that you select is designed for use with the
equipment that you are using. Some of the variables that effect blade/wheel perfor-
mance are:
