To replace the sponge plate, unplug the machine from
the mains.
The sanding plate has Velcro on both sides, therefore to
change it you have to pull it until it comes off the base
plate and replace it with a new one. (C, Fig. 3).
8. CHANGING THE PLATE COVER
Cover functions: The brush on the edge of the plate cover
has the dual function of keeping the abrasive disc properly
aligned with the surface it is sanding and to enable the
vacuum cleaning system to work more effectively.
The brush on the cover becomes worn with constant
machine use, no longer guaranteeing the correct position
of the plate and effective dust collection. When this
occurs you should change the whole cover.
Change the cover in the following way:
• Unplug the machine.
• Press the shaft lock (D, Fig. 4), turning the plate until
the shaft is locked in position. Turn the sanding plate
anti-clockwise to remove it from the machine.
• Now press the cover down against the spring (Fig. 5)
and with the help of some special pliers, take off the
retaining ring attaching the cover to the gear box.
• Finally, remove the dust collector tube with care (Fig.
6), take off the plate cover and replace it, turning it in
the opposite direction for attachment.
9. VACUUM CLEANER TUBE INSTALLATION
• Unplug the machine.
• Take the connector terminal off the vacuum hose first
and attach the bayonet connector (E, Fig 7) which is
included as part of the machine's equipment.
• Now insert the bayonet connector (E, Fig. 7) on the
dust collector tube into the swivel connector (F, Fig. 7)
on the machine.
• 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. 7).
• To remove the vacuum tube, turn it in the opposite
direction.
10. 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 adjus-
table power, you may adjust the vacuum suction power
according to the surface area you are working on.
• Adjust the speed wheel (H, Fig. 8) to obtain the right
suction.
• Start with low suction and gradually increase it by
turning the wheel H, Fig. 8), 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.
11. 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.
Push the trigger switch to start up the machine (I, Fig.
1) and release it to stop it.
If you wish to keep the machine running constantly, you
can set the switch lock (J, Fig. 1). To take off the switch
lock, press the switch and then release it.
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.
12. 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
