Diamond Blade Trouble Shooting:
Problem
Cause & Action
Loss of Tension in Diamond Blade
Blade being used on misaligned saw. Check for proper saw alignment.
Blade is excessively “hard” for material being cut, creating stress on steel blade
center. Check that blade is correct for material being cut.
Different diameter or undersize blade flanges creates uneven pressure on blade
center. Use proper size flange on each side of blade. Never use worn or dam
-
aged flanges.
Blade operated at improper speed (R.P.M.). Make certain blade shaft is turning at
the proper speed (R.P.M.) for blade size. Check R.P.M. using a tachometer.
Blade improperly mounted on arbor. Could become bent when flanges are tight
-
ened.
Segment Loss
Blade is too “hard” for material being cut. Use “softer” blade specification.
Overheated blade, detected as “blue” color on steel center. Check that water
supply is adequate and not blocked.
Saw is twisted while cutting. Saw only in a straight line.
Blade Bore is worn to an eccentric shape (ovalized). Replace worn blade and
worn spindle.
Segment knocked off during mounting our transport. Avoid rough handling of
diamond blade. Never transport the machine with the diamond blade mounted.
Cracked Blade Core
Blade is too “hard” for material being cut. Use “softer” blade specification.
Overheated blade, detected as “blue” color on steel center. Check that water
supply is adequate and not blocked.
Saw is twisted while cutting. Saw only in a straight line.
Cracked Blade Segments
Blade is too “hard” for material being cut. Use “softer” blade specification.
Blade operated at improper speed (R.P.M.). Make certain blade shaft is turning at
