Diamond Blades
WARNING
• DO NOT exceed the blade’s
maximum recommended speed
when cutting. Excessive blade
speeds can cause blade breakage, resulting in
serious injuries and/or death!
• DO NOT use damaged blades when cutting to
avoid harming yourself, others, or the saw.
• Always use an appropriate size blade and the
correct blade type based on the cutting task
and the type of material being cut.
Using the proper blade (size and type) preserves the
blade and improves cutting and operator efficiency,
resulting in lower costs. Refer to the Association of
Equipment Manufacturers (AEM) safety brochure for
diamond blades or www.diamondproducts.com for
additional blade information.
Inspecting the Blade
Inspect each blade prior to installation and discard all
damaged blades. Inspect all blades for:
• Cracks, nicks, and dents
• A damaged and/or deformed arbor (center hole)
• Darkness and/or discoloration near edge of blade
• A deformed blade circumference
• Segment loss and/or segment cracks
• Core wear
• Bending
• Uneven side-widths
Blade Speed
Refer to the blade packaging information or to the
information printed on the blade for the recommended
and maximum recommended blade speeds when
cutting. DO NOT exceed the maximum recommended
cutting speed. DO NOT use a blade that is rated with a
lower maximum recommended speed than the blade
shaft speed.
Wrench
Use the wrench when installing or removing a blade.
Apply force to the opposite end of the wrench and
tighten the blade shaft nut to 50 ft-lb (67.8 Nm) to
properly secure the outer flange and blade. This
measurement can be verified with a torque wrench.
