CAUSE

REMEDY

Be certain the blade is properly mounted on the arbor before tightening the flange.

Blade flanges have been improperly tightened, permitting the blade to rotate on the shaft.

Always wrench tighten the arbor nut. Never hand tighten. Always use hexagonal nuts.
Never use wing nuts.

Blade flanges, drive phi or the arbor shaft are worn and not providing proper blade support.

Check the blade flanges, arbor shaft and
drive pin for wear, foreign matter and proper tightness. Both flanges should be no less diameter than recommended by the manufacturer. Replace worn parts.

CAUSE

REMEDY

Blade is too hard for the materials being cut. (Examples: block or general purpose blade being used for extended period on hard brick. Asphalt blade being used to cut hard concrete.)

Consult the dealer or manufacturer for the proper blade to cut materials on the
job.

Insufficient power to permit the blade to cut properly. (Loose V-belts, low
voltage, motor lacks horsepower).

Check belts, voltage/amperage and horsepower.

Blade segments still appear to have plenty of life, but the blade will not cut.

Some blades have a non-diamond bearing section in a backing at the base of
the diamond segment for better adherence to the steel core. A blade used to
this stage has worn out in the normal manner and should be replaced.

Blades become glazed due to excessive RPM.

Match blade specification and diameter to the machine RPM and cutting conditions.

Blade becomes glazed due to inadequate pressure against the material being cut.

Ensure proper pressure to keep the blade sharpened, while avoiding an excess
of pressure.
