Maintenance
CRACKS IN CORE
• 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.
• Blade flutters in cut as a result of losing
blade tension.
• Blade specification is too hard for the
material being cut.
Troubleshooting
• Flush water system.
• Check flow to both sides of
blade.
• Replace bad bearings, worn
arbor shaft or misalignment to
spindle.
• Check alignment for
squareness, both vertically and
horizontally, of the saw blade.
• (In wet cutting) Insufficient water (usually
on one side of blade).
• Equipment defects also can cause the
segments to wear unevenly.
• Saw head is misaligned.
UNEVEN SEGMENT WEAR
• Use a blade with a softer
bond/matrix.
• Blade is too hard for material being cut.
SEGMENT CRACKS
SEGMENT LOSS • Blade overheats because of lack 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.
• (Wet Cutting) Check water
lines. Make sure flow is ad-
equate 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.
PROBLEM
REMEDY
CAUSE
• Make certain blade RPM is
correct.
• Check water flow, distribution
and lines.
• Tighten the blade shaft nut.
• Make certain 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.
• 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/flanges.
• Blade is too hard for the material being
cut.
