Below
we
offer
a series
of suggestions
which
will
enable
you
to
resolve
some
of the
most frequent
problems
which
arise
when
sanding
wooden
flo-
ors.
.
Sometimes
the
belt
make
a
noise as if
it is
slip-
ping.
This
means
that it is
not
fitted tighfly
enough
or
that
it is
worn
and
need
changing.
.
The
ball
bearings
are
protected
against
dust
and
are
self-lubricating.
However,
they have
a limited
life
span
depending
on
the
amount
of time
the
machine
is in
use.
Chances
are
that
the
machine
will have
sucked
in
a nail,
a
piece
of wood
or
any other
foreign
body
which
will
have
blocked
the
blades
of
the fan.
To
solve
this
problem,
try
to
turn
the
blades
manually
and
remove
the foreign
body
that is
blo-
king
it.
.
Firstly,
clean
the
floor
to
make
sure
that
there
are
no
nails
lying
around.
.
Brush
the
floor
before
sanding
to
avoid
remains
of
materials
which
could
damage
the
rubber
drum.
.
By
way
of indication,
their
useable
life
is approxi-
mately:
.
Take
care
not
to
insert
sandpaper
which
is
too
long,
as this
will
cause
it to fold
and
leave
marks
on
the
floor.
lt
could
also
cause
the sandpaper
to
break
while
working.
.
lf the
motor
functions
haltingly
once
it
has
been
switched
on
and
set in
motion,
this
means
that:
a)The
electric
voltage
is too
low.
b)The
cable
is
too
long
or the
cross-section
is
inappropriate.
c)The
work
capacitor
is
defective.
d)The
motor
is
defective.
.
lf the
motor
does
not
start, thrs
means
that:
a)The
electric
voltage
is too
low.
b)The
starting
capacitor
is
defective.

No
matter
what
the case,
if
you
hear
a strange
noise,
check
whether
it is
coming
from the drum,
motor
or fan.
Run
the
motor
together
with
the
drum
alone
and
then
the motor
with the
suction
tube
alone,
which
will
make
it easy
to
pinpoint
the
noise.
Once found,
the
faulty
bearing
has to
be
changed.
.
Should
you
notice
that
the
fan is
not turning,
the
machine
is
not vacuuming,
and
that the fan
belt
is
making
a slipping
noise,
STOP
THE
MOTOR.
