FAULT PROBABLE CAUSE REMEDY
Irregular work of the blade due to the lack
ofteethcancausedeectioninthecut;
check blade and if necessary replace it.
Check level of liquid in the tank. Increase
theowoflubricatingrefrigerant,checking
that the hole and the liquid outlet pipe are
not blocked.
Check the emulsion percentage.
Thesupportandguideangeoftheband
are so worn out that they cannot ensure
the alignment of the blade, causing faulty
cutting;bladerollinganddrawingtracks
can have become tapered. Replace them.
Clean with compressed air.
Check that the tightening handwheel is
against the set screw that ensures ideal
tightening.
Decrease advance, exerting less cutting
pressure. Adjust the braking device if
mounted on the machine.
Use a superior quality blade.
Replace it.
Blade with not enough teeth is being
used, try using one with major density
(see Chapter “Material classication
and blade selection” in the Blade Types
section).
Approach head as near as possible to
material to be cut so that only the blade
section employed in the cut is free, this will
preventdeectionsthatwouldexcessively
stress the blade.
Check that the tightening handwheel is
against the set screw that ensures ideal
tightening.
Check level of liquid in the tank. Increase
theowoflubricatingrefrigerant,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.
