Core Cracks
1.Blade too hard for the material being cut
2.Excessive cutting pressure,results in the blade core bending and flexing.Metal fatigue will eventually cause core to rack.
3.Worn shafts,damaged machine bearings or blade insecure mounting.
Damaged Arbor Hole
1.Make sure that blade is mounted on the proper diameter of the spindle before.Make sure that the pin holes slide over the drive pins.
2.The blade will spin or vibrate on the spindle if the flanges are not properly tightened.
3.The blade will pound if the saw shaft is badly worn or grooved.
Out Of Round
1.Blade shaft bearing may possibly be worn.Fit new bearing and ensure regular lubrication.
2.Blade too hard for the material being cut.
3.Blade shafr bent,worn or grooved.
4.Clamp plates are not properly,tightened,allowing the blade to slip on the shaft.
5.Blade is not mounted correctly,or shaft is grooved.
Blade Not Cutting
1.Check that specification is correct for the material.
2.Blade is too hard for the material being cut.
3.Blade has finished or glazed,probably due to bond being too hard.
4.Machine is not powerful enough,or suffers loss of Power.
5.New blade is not well exposed.
6.Segment has mushroomed over due to the bond being too hard.
7.Check direction of rotation.
Segment Loss
1.Blade has twisted or jammed in the cut because the materials was not held firmly.
2.Machine has been twisted or turned while blade is in the cut.
3.Blade core has undercut due to cutting below the asphalt into the sub-base.
4.Blade is too hard for the materials being cut,resulting in the blade hammering in the cut
5.Blade is deflected in the cut due to the blade flanges being worn or deformed and failing to provide proper support
6.Inadequate water supply
Segment Cracks
1.The blade is too hard for the materials for being cut
2.Peripheral speed of the balde is excessive
Undercutting
1.Make sure that the blade specification has offset segments to assist removal of the slurry from the cut
2.Make sure that the balde is not cutting below the asphalt into the sub-base constant rubbing of the loose material causes premature wear and has no beneficial effect on the cut surface
3.Make sure that the water supply is correct as increased water flow will wash slurry from the contact area and reduce undercutting
Uneven Segment Wear
1.Wet cutting-insufficient water
2.Saw head misaligned
3.Equipment defective
Tension Loss
1.Blade core overheated
2.Check machine running at correct rpm,that the flanges are of the correct and same size and there is no wear on the machine bearing
3.The blade is too hard for the application
4.The balde is spinning on the spindle
5.The blade is not cutting in straight lines only
Rapid Wear
1.Using the wrong specification for the material being cut
2.If wet cutting,inadequate water supply
3.Blade wears out of round
3.Loss of power on the machine due to slipping belts
Overheating
1.Overheating can cause many other problems such as core cracks,loss of tension and segment loss,overheating can be shown by black or bluish discolouration on the core
2.Wet cutting inadequate water supply or bocked jets
3.Dry cutting-excessive cutting pressure
Blade Wobbles
1.Blade shaft is bent or grooved, bearings have failed blade out of tension
2.Incorrect blae speed
3.Blade is bent
