pressure.
The best sanding results are achieved with moderate
pressure. Sanding quality and performance mainly
depend on the right choice of abrasive disc.
• The best sanding technique consists in long strokes
back and forth, keeping the head in constant motion.
Do not let the machine stop in the same place, since it
will leave marks on the surface.
• Turn the machine off when the sanding work has
finished.
Sanding near the edges:
• The sander has an extractable head cover section that
makes it possible to reduce the distance at the side bet-
ween the wall/ceiling and the sanding plate. (Fig. 10)
• When the machine is working without the head cover
section, the vacuum cleaner loses effectiveness, so it
should only be extracted when necessary and should
be refitted as soon as possible.
• To take off the cover section:
• Unplug the machine.
• Press between the two snap rings fastening the
section and take it off its mount (Fig 10).
• Keep the extracted section close at hand in a safe
place to be able to fit it on again.
• Proceed in the same way to fit the section.
Recommendations:
Ensure you use the best disc for the sanding to be done.
If the abrasive discs are too coarse-grained they remove a
lot of material as they work; this is sometimes too much
and makes it difficult to control, while those that are
too fine-grained tend to get easily muffled.
Try to avoid sharp points and nails when sanding, as these
can damage the abrasive disc and even the sponge plate.

13. MAINTENANCE AND CLEANING

Turn the machine off at the mains before performing
any operation.
• All maintenance work or repairs on the machine that
require the motor casing to be opened can only be carried
out by an authorised official service centre.
• Regularly check the state of the lead and the plug, and
change them if they are damaged using an authorised
official service.
• Always keep the air circulation windows on the casing
clean to ensure motor cooling.
• Clean the dust collector tube connection with the
plate cover so that it is not obstructed.
Changing brushes:
Brushes should be changed when they have a minimum
length of 6 mm.
• To inspect or replace the brushes, first turn the machine
off at the mains.
• Remove the vacuum tube and take off the right and
left handles by removing the screws (K, Fig. 10) that
10
attach them.
• Unscrew the two screws (L, Fig. 10) that fasten them
to the electronic circuit and move the latter to one side,
being careful not to damage the circuit connections.
• Unscrew the two screws (M, Fig. 11) attaching the
brush-holder.
• Inspect or change the brushes if necessary.
• It is advisable to allow the machine to run for a few
minutes with no load after changing the brushes.

15. NOISE AND VIBRATION LEVEL
The noise and vibration levels of this device have been
measured in accordance with European standard EN
60745-1 and serve as a basis for comparison with other
machines with similar applications.
The indicated vibration level has been determined for
the device's main applications and may be used as an
initial value for evaluating the risk presented by expo-
sure to vibrations. However, vibrations may reach levels
that are quite different from the declared value under
other application conditions, with other tools or with
insufficient maintenance of the electrical device or its
accessories, reaching a much higher value as a result
of the work cycle or the manner in which the electrical
device is used.
Therefore, it is necessary to establish safety measures
to protect the user from the effects of vibrations, such
as maintaining both the device and its tools in perfect
condition and organising the duration of work cycles
