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.
