to
the

position
to
put
the
machine
in
standby
mode.
Check
the
potentiometer
(8),
and
ensure
that
it
is
set
to
the
working
speed.
If

OPERATING
THE
MACHINE
Guide
the
machine
in
straight
lines
across
the
floor,
slightly
overlapping
the
previously
completed
surface
with
each
new
line.
Work
at
a
constant
speed,
allowing
the
tools
time
to
work
at
a
speed
appropriate
for
the
tools’
grit
size.
Avoid
vibrations.
Do
not
stop
the
machine
while
tools
are
still
running
as
they
will
mark
the
surface
of
the
floor.
When
working
wet,
select
the
destination
of
the
water
feed
with
the
water
tap
(fig.
4.2
‐
1)
and
periodically
run
the
pump
(fig.
4.10
‐
11)
to
release
water
onto
the
floor
surface.
Starting
the
pump
is
possible
only
if
the
machine
motor
is
on.
When
working
dry,
check
the
floor
surface
periodically
for
dust
accumulation.
Check
regularly
to
see
if
your
vacuum
works
properly
STOPPING
THE
MACHINE
The
stopping
of
the
machine
must
be
done
gradually
until

motor
stops.
Do
not
stop
moving

to
rest,
as
the
tools
could
damage
the
surface.
To
stop
the
machine:
1.Push
the
STOP
button
(10)
.
2.Turn
the

(9)
switch
in
position

and
the
green
light
will
turn
off.
While
working
do
not
turn
off
directly
from
the
READY
switch
or
from
the
Emergency

but
follow
the
steps
above.
Use
the
Emergency
button
(12)
only
in
an
emergency.

ALARM
The
Reset
button
(4)
will
light
when
the
inverter
goes
into
alarm
mode.
The
most
common
failure
is
motor
overload.
To
exit
alarm
mode,
push
the
reset
button
(4).
A
code
on
the
inverter’s
display
indicates
the
type
of
the
alarm.
When
the
same
alarm
is
repeated
several
times,
it
is
imperative
to
find
and
eliminate
the
cause
of
it,
otherwise
the
inverter
can
become
damaged.
