FAULT
FAULTY CUT
STREAKED CUTTING
SURFACE
NOISE ON GUIDE
BLOCKS
PROBABLE CAUSE
Broken teeth
Insufficient lubricating refrigerant or
wrong emulsion
Worn out flywheels
Flywheel housing full of chips
Too fast advance
Poor quality blade
Worn out blade or with chipped and/or
broken teeth
Wrong tooth pitch
Blade guide block too far from material
to be cut
Insufficient lubricating coolant or wrong
emulsion
Chipped bearings
Worn out or damaged pads

REMEDY
Irregular work of the blade due to the
lack of teeth can cause deflection in the
cut; check blade and if necessary
replace it.
Check level of liquid in the tank.
Increase the flow of lubricating coolant,
checking that the hole and the liquid
outlet pipe are not blocked. Check the
emulsion percentage.
The support and guide flange of the
band are so worn out that they cannot
ensure the alignment of the blade,
causing faulty cutting; blade rolling and
drawing tracks can have become
tapered. Replace them. Clean with
compressed air.
Decrease advance, exerting less
cutting pressure. Adjust the braking
device.
Use a superior quality blade.
Replace it.
Blade used probably has too large
teeth, use one with more teeth (see
"Material classification and blade
selection" in the Blade Types section).
Approach it as near as possible to
material to be cut so that only the blade
section employed in the cut is free, this
will prevent deflections that would
excessively stress the blade.
Check level of liquid in the tank.
Increase the flow of lubricating coolant,
checking that the hole and the liquid
outlet pipe are not blocked. Check the
emulsion percentage.
Dirt and/or chips between blade and
guide bearings. Replace them.
Replace them.
