WOBBLINGS CAUSES > Blade is mounted on a damaged or worn M/C. > Blade is not tensioned properly. > Blade runs at improper speed. > Blade is bent as a result of twisting.
	OUT-OF-ROUND BLADE CAUSES > Shaft bearings are worn. > Engine is not properly turned, causing surges in blade rotation. > Blade arbor hole is damaged from mismounting.
	ARBOR OUT-OF-ROUND CAUSES > Blade collar is not properly tightened, permitting blade rotation or vibration on the shaft. > Worn, bent or dirty flange which do not allow proper blade clamping.
	LOSS OF TENSION CAUSES > Steel center has been overheating as a result of blade spinning on the arbor or from rubbing the side of material being cut. > Unequal pressure at blade clamping collars. > Improper blade specification: blade is too hard for material being cut.
	UNEVEN SEGMENT WEAR CAUSES > Insufficient water, generally on one side of the blade, which reduces side clearance. > Equipment defects which cause the segments to wear unevenly. > Saw head is misaligned.
	CRACKS IN STEEL CENTER CAUSES > Blade wobbles in cut as a result of loss of blade tension. > Bond is too hard for material being cut.
	BLADE WILL NOT CUT CAUSES > Bond is too hard for material being cut. > Blade has become dull as a result of being used on material that is too hard.
	SEGMENT CRACKS CAUSES > Bond is too hard for material being cut.
	LOSS OF SEGMENT CAUSES > Material is not firmly secured. > Overheating due to insufficient water. > Steel center is worn from undercutting. > Defective blade collars are setting blade out of alignment. > Blade is too hard for material being cut. > Blade is cutting out-of-round, causing a fluttering motion. > Improper blade tension.
