Cause: Blade is too hard for 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.)
Remedy: Consult dealer or manufacturer for proper blade to cut materials on job.
Cause: Insufficient power to permit blade to cut properly. (Loose Vbelts, low voltage, motor lacks horsepower)
Remedy: Check belts, voltage, horsepower.
Cause: Blade has become dull because of continuous use on fairly hard or vitrified material.
Remedy: Dress with abrasive material until diamonds become exposed again. (This may be necessary occasionally, but if dullness occurs too often, then the blade is probably too hard for the material.)
Cause: Blade segments appear to still have plenty of life, but blade won't cut.
Remedy: Some harder-bonded blades designed for abrasive materials require a non-diamond bearing section at the base of the diamond segment for better adherence to the steel core. A blade used to this has worn out in the normal manner and should be replaced.
