SAR 331 SA GDS
FAULT PROBABLE CAUSE 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 refrigerant, 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 if
mounted on the machine.
Use a superior quality blade.
Replace it.
Blade used probably has too large teeth; use
one with more teeth (see “Material classi-
fication 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 em-
ployed in the cut is free, this will prevent de-
flections that would excessively stress the
blade.
Check level of liquid in the tank. Increase the
flow of lubricating refrigerant, 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.
