4. ELECTRICAL CONNECTION
Check the power supply is always the same voltage as
that indicated on the machine's specifications plate.
The machine may at not be used under any circumstances
if the power lead is damaged.
A lead that is damaged or in poor condition should be
immediately replaced by an authorised technical service;
do not try to repair it yourself.
Working with a lead in poor condition can cause elec-
trical accidents.
5. ELECTRONIC CONTROLS
Smooth starting: Electronic starting controls that ensure
a smooth start and gradual increase in speed.
Controlled speed: You can set the uninterrupted disc
turning speed, from 650 to 1,300 rpm with no load, by
using the thumb wheel (A, Fig. 1). You can in this way
set the best possible sanding speed for each material.
The electronic speed adjuster will keep its speed constant,
even at full loads to provide perfect sanding.
We advise using the highest speeds when a lot of material
needs to be removed and low speeds for finer sanding
and to improve control of the machine.
6. ATTACHING THE ABRASIVE DISC
Unplug the machine. Take off the used disc, ensuring
that the sponge plate remains in position.
Carefully align the holes in the disc (B, Fig. 2) with those
on the plate and press the disc so that it is held in place
by the Velcro on the plate.
7. CHANGING THE SPONGE PLATE
The sponge plate should be perfectly smooth for proper
sanding and good results.
If the pad has become misshapen or damaged by work,
the sanding will be irregular and poor quality. You should
change the pad immediately when it has been damaged.
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
adjustable 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.
