• Fit the bayonet connector (O, Fig. 8) into the swivel
connector (P, Fig. 8) on the end of the handle.
• 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.
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 ASC682 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 (Q, Fig. 9) to obtain the right
suction.
• Start with low suction and gradually increase it by
turning the wheel Q, 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.
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.
Start-up:
First press the Power Button (B, Fig. 1) to energize the
tool. While holding the machine with your left hand on
the column, and your right hand on the main handle,
press the power button (D, Fig. 1) of the motor to switch
on the tool.
Anticipate and be ready for the start up
torque when the machine first starts.
NOTE:
After the motor switch is pressed, the controller
sychronizes with the rotor position, and there will be a
1-2 second delay before it begins rotating. This is normal.
Stopping:
To stop the machine, simply push the switch (D, Fig. 1).
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. ADJUSTING THE ROTATION SPEED
The speed of the machine is variable to suit different
tasks. It can be adjusted by pressing the "Up" and "Down"
Speed Selector Buttons (C, Fig. 1).
The selected setting will appear on the indicator screen
(A, Fig. 1).
Generally, you should use higher speeds for fast stock
removal and lower speeds for more precise control.
Note:
For a fine finish sanding, use fine grit sandpaper
discs at a lower speed.
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.
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 ASC682 vacuum cleaner or another
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.
