TROUBLESHOOTING Blade Will Not Cut
Uneven Segment Wear
Crack in Segments
Blank Undercutting
Causes
New blade is not well exposed.
Causes
Saw head misaligned. Equipment defective.
Causes
Remedies
Blade is too hard for the material being cut.
Use a softer bond. Consult your supplier or our technical department for the correct bond for material being cut.
Blade has polished or glazed, probably due to bond being too hard.
Ensure belts are tight and use adequate horsepower for the cutting application.
Allow blade to sharpen itself by cutting shallow passes.
Segment has mushroomed over due to the bond being too hard for material being cut or insufficient water.
Use softer bond or ensure adequate water supply.
Wet cutting - insufficient water, generally on one side of the blade.
Ensure water is distributed evenly to both sides of the blade.
Check water nozzles are not blocked.
Check saw head alignment for both horizontal and vertical squareness.
The blade is too hard for the material being cut.
Peripheral speed of the blade is excessive.
Ensure correct rotation speed for the blade diameter.
Causes
Remedies
Check machine bearings and spindle.
Remedies
Use a softer, more free cutting blade.
Remedies
Wearing of steel blank under the segments when cutting abrasive materials.
Do not cut into sub-base beneath asphalt, as sand and gravel will cause excessive wear to steel blank.
Use blade with tungsten or diamond undercutting protection.
Increase the water flow to flush away abrasive slurry.
