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.
