TROUBLE SHOOTING GUIDE
Cause
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.
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.
