Troubleshooting
BLADE WILL NOT CUT • Select proper blade for material
being cut.
• Sharpen by cutting on softer
abrasive material to expose
diamonds. If continually
sharpening, the blade is too
hard for the material being cut.
• Break-in on the material to be
cut. If it does not dress itself,
sharpen as you would a dull
blade.
• Blade is too hard for material being
cut.
• Blade has become dull.
• Blade does not cut material it was
specified for.
UNDERCUTTING THE CORE • Use water to flush out fines
generated during cutting
• Use wear-retardant cores.
• Abrasive wearing of the core faster than
the segments.
BLADE WOBBLES
• Check for bad bearings, bent
shaft, or worn mounting arbor.
• Check collars/flanges to make
sure they are clean, flat and of
correct diameter.
• Set engine at proper rpm.
• Use proper size blade collars/
flanges.
• DO NOT USE bent blade.
Contact blade manufacturer.
• Blade is on a damaged or worn saw.
• Worn collar.
• Blade runs at an incorrect speed.
• Collar /flange diameters are not identical.
• Blade is bent as a result of dropping or
twisting.
PROBLEM
REMEDYCAUSE
ARBOR HOLE OUT-OF-
ROUND
• Make certain the blade is
mounted on the proper shaft
diameter. Tighten the shaft nut
with a wrench to make certain
that the blade is secure.
• Clean collars/flanges, make sure
they are not worn.
• Tighten arbor nut.
• Make sure the pin hole slides
over drive pin.
• Collars/flanges are not properly
tightened, permitting blade to rotate or
vibrate on the shaft.
• Collars/flanges are worn or dirty.
• Blade is not properly mounted.
• Install new blade shaft
bearings or blade shaft, as
required.
• Tune engine according to
manufacturer's manual.
• If core is worn or arbor hole
damaged, DO NOT USE.
Contact blade manufacturer.
• Use proper blade. Consult
blade manufacturer.
• Replace worn shaft or mount-
ing arbor bushing.
• Make certain that drive pin is
functioning.
• Tighten spindle nut.
• Shaft bearings are worn.
• Surges occur because engine is not
properly tuned.
• Blade arbor hole is damaged from
incorrectly mounting the blade.
• Bond/matrix is too hard for material.
• Blade is slipping, wearing one half of
blade more than other.
