Dust Collection; Starting And Stopping The Machine; How To Use The Machine - Virutex LPC97S Gebrauchsanweisung

• When the bayonet connector is fully inserted, hold
the swivel connector to stop it turning and turn the
bayonet clockwise until it is locked in position (Fig. 8).
• To remove the dust collector pipe, you will have to
turn it in the opposite direction.

11. DUST COLLECTION

Prolonged exposure to sanding dust from walls can
affect breathing. Always use a vacuum cleaner with a
suitable bag fitted for dust from walls.
If you do not use a suitable bag, it will
increase the dust level in the working
area and prolonged exposure to this risk
may cause breathing problems.
Adjusting vacuum cleaning power:
• If you use the Virutex ASC482U compact vacuum
cleaner, or another vacuum cleaner with suitable
adjustable power, you may adjust the vacuum suction
power according to the surface area you are working on.
• Adjust the speed wheel (H, Fig. 9) to obtain the right
suction.
• Start with low suction and gradually increase it by
turning the wheel H, Fig. 9), until you achieve the right
suction.
• A high suction level makes the job of sanding
ceilings and walls easier.
• If the suction level is excessive it will cause the
machine to vibrate, make it difficult to direct it and
could overload it. If this occurs, you should stop work
immediately until the machine has cooled down.

12. STARTING AND STOPPING THE MACHINE

Ensure the mains voltage is the same as indicated on the
specifications plate and that the switch is off in the "O"
position before plugging the machine in.
Start-up:
While holding the machine with your left hand on the
column or on the D-handle, and your right hand on the
main handle, press the switch (I, Fig. 1) to position "I".
Stopping:
To stop the machine, simply push the switch (I, Fig. 1)
to position "O".
The machine does not stop immediately and the abrasive
disc continues to turn for some time before stopping.
Ensure that it does not come into contact with anybody
or anything and do not let go of the machine until the
abrasive disc has completely stopped.

13. HOW TO USE THE MACHINE

To work safely and to remain in control of the machine
at all times, you should always hold it with two hands.

The best way to do this is to hold the machine with one
hand on the main handle, the one at the rear, and the
other hand on the part of the column covered with the
softgrip, or by using the D-handle if it is fitted.
It is very important to stand firmly on both feet, parti-
cularly when working on platforms.
Sanding:
• If the wall sander and vacuum cleaner are ready, the
safety measures have been taken and the necessary
safety equipment is in use, the machine can be started
first followed by the vacuum cleaner.
If you use the Virutex ASC482U vacuum cleaner or ano-
ther vacuum cleaner with automatic built-in starting,
you will only have to start up the machine.
• Place the machine on the surface you are going to
sand, making smooth contact with the latter and with
minimum pressure in order to keep the sanding head
flat against it.
• You can now reset the speed to the ideal speed for
the work to be done.
• The articulated head allows the abrasive disc to follow
the contours of the work surface.
• Do not overload the machine by applying excessive
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
between 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 retaining parts 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.
