Shaft bearings are worn

Install new blade shaft bearing as required

Blade arbor hole is damaged from previous mismounting

Replace worn shaft or mounting arbor bushing

Bond is too hard for material, causing a "rounding" and wearing one half of the blade more than the other

Make certain that drive pin is functioning

Blade is too hard for material being cut

Select proper blade specification for mateial being cut

Blade has become dull as a result of being used on too hard a material

Tune engine according to manufacturer's manual

Insufficient water(usually on one side of blade)

Flush out water system and check flow and distribution to both side of blade

Equipment defects cause the segments to wear unevenly

Replace bad bearings, worn arbor or misalignment to spindle

Saw is misaligned

Check saw head aligned for squareness both vertically and horizontally

Blade collar is not properly tightened, Permitting blade rotation or vibration on the shaft

Tighten the shaft nut with a wrentch to make certain that the blade is adequately secured

Blade collar is not properly tightened, Permitting blade clamping

Clean blade collars, making certain they are not worn

Blade is not properly mounted

Abrasion of steel center due to highly abrasive fines generated during cutting

Use as much water as possible to flush out fines generated curing cutting or use wear-retardant cores

Cutting through material into sub-base

Blade is too hard for material being cut

Use a blade with a softer bond

Blade runs at improper speed

Check for bad bearings, bent shaft, or worn mounting arbor

Blade collar diameters are not identical

Check blade collar discs to make sure they are clean, flat and of correct diameter

Blade is bent as a result of dropping or twisting

Make certain that blade shaft is running at recommended RPM to match tensioned speed of blade

Overheating due to lack of water

Check water feed lines and make sure flow is adequate on both sides of blade

Steel center is worn from undercutting

Use sufficient water to flush out the cut

Defective blade collars are causing blade misalignment

Clean blade collars or replace

Blade is too hard for material being cut

Use proper blade specification for material being cut

Blade is cutting out of found, causing a pounding motion

Replace worn bearing

Improper blade tension

Ensure blade is running at correct RPM, blade is tensioned for correct RPM

Blade flutters in cut as a result of blade losing tension

Blade specification is too hard for the material being cut

Use a softer bond to eliminate stress which create cracks

Bad blade shaft bearing

Replace blade shaft bearing

Steel center has been overheating as a result of blade spinning on arbor

Check water flow, distribution and lines and tighten the blade shaft nut

Steel center has been overheating from rubbing the side of material being cut

Make certain blade RPM is correct so the blade operates at its tensioned speed

Unequal pressure at blade clamping collars

Blade clamping collars must be identical in diameter and the recommended size

Improper blade specification: blade is too hard for the material being cut

Use a softer bonded blade to reduce operating stresses
