Dry cutting
Never operate any saw without safety guards in place.
Do not exceed maximum operating speed established for blade diameter.
Do not force blade into material: allow blade to cut at its own speed.
Do not make long continuous cuts. Never dry cut for more than 30 seconds at a time. Allow blade to cool.
Do not cut or grind side of blade or cut a curve or radius. Do not cut dry with blades recommended for wet cutting.
Do not operate saw with blade diameter larger than machine's capacity.

CAUSE
• (in wet cutting) insufficient water (usually on
one side of blade).
• Equipment defects can also cause the segments
to wear unevenly.
• Saw head is misaligned.
• Blade is too hard for material being cut.
• Blade overheats because of coolant (water or
air).
• Core is worn from undercutting.
• Defective collars / flanges set blade out of
alignment.
• Blade is too hard for material being cut.
• Blade is cutting out of round, causing a
pounding motion.
• Improper blade tension.
• Blade flutters in cut as a result of losing blade
tension.
• Blade specification is too hard for the material
being cut.
• Core overheating.
• Core overheating as a result of blade spinning
on arbor.
• Core overheating from rubbing the material
being cut.
• Unequal pressure at blade clamping collars/
langes.
• Blade is too hard for the material being cut.

REMEDY
• Flush water system.
• Check flow to both sides of blade.
• Replace had bearings, worn arbor shaft or
misalignment to spindle.
• Check alignment for squareness, both vertically
and horizontally, of the saw blade.
• Use a blade with a softer bond / matrix.
• (Wet Cutting) Check water lines.
• Make sure flow is adequate on both sides of
blade and there are no blockages.
• Use sufficient water to flush out the cut.
• (Dry cutting) Run blade free of cut periodically
to air cool.
• Clean collars / flanges or replace if they are
under recommended diameter.
• Use proper blade specification for material
being cut.
• Replace worn bearings; realign blade shaft or
replace worn blade mounting arbor.
• When ordering blades match shaft speed of
saw.
• Check spindle speed to ensure blade is running
at correct RPM.
• Avoid twisting or turning blade in the cut.
• Tighten the blade shaft nut.
• Make sure blade is running at proper speed and
that drive pin is functioning properly.
• Use a softer bond / matrix to eliminate stress.
• Make certain blade RPM is correct.
• Check water flow, distribution and lines.
• Tighten the blade shaft nut. Make certain that
the drive pin is functioning.
• Properly align the saw to square cut.
• Collars / flanges must be identical in diameter
and the recommended size.
• Use a softer bond / matrix to reduce stress.
