FAULT
PROBABLE CAUSE REMEDY
Broken teeth
Insufficient lubricating refrigerant or
wrong emulsion
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.
FAULTY CUT
Worn out flywheels
Flywheel housing full of chips
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.
STREAKED CUTTING
SURFACE
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
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.
NOISE ON GUIDE BLOCKS
Chipped bearings
Worn out or damaged pads
Dirt and/or chips between blade
and guide bearings. Replace them.
Replace them.
