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 anges creates uneven pressure on blade
center. Use proper size ange on each side of blade. Never use worn or dam-
aged anges.
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 anges are tight-
ened.
Segment Loss Blade is too “hard” for material being cut. Use “softer” blade specication.
Overheated blade, detected as “blue” color on steel center. Check that water
supply is adequate and not blocked.
