off. The switch must be set back into the stop position
before turning on the tool again.
Progressive start up.
It allows the tool to be started at low speed and increase
speed gradually. The axle turns on and speeds up gradually
without jerking until the set speed is reached.
Constant speed.
The turning speed remains constant regardless of the
pressure on the working surface. Constant turning speed
ensures optimum sanding quality.
Speed selector.
The speed selecting knob 17 allows the user to select
the appropriate turning speed (it can be changed even
during operation). The user can test and select the desi-
red working speed depending on the working material.
If you have been operating this tool at low speed for
a long time, 3-minute cooling time should be allowed.
To cool the machine down, set the speed selecting knob
at the top speed position and make the tool work idle.
9. RECOMMENDED USE FOR THIS POWER TOOL
Choose the right brush.
Select the most appropriate brush (nylon, metal, sand
paper…) for the job.
The intended use for each brush type should be indi-
cated on its packaging. You may also ask your supplier
for guidance.
General recommendations.
Turn on the tool and let it turn at the selected speed.
Then, slowly bring the brush 26 onto the working piece.
Do not apply exceeding pressure on the tool. Excess of
pressure will not produce better results and you may
cause the motor to overload as well as premature brush
wear. Move the tool at moderate constant speed. Do not
make sudden movements or fluctuations. It is strongly
recommended that you make a test on a trial surface
in order to determine the recommended turning speed.
Regulate the position of the wheel 12 as the brush is
being worn out (Fig. 5).
10. MAINTENANCE
Unplug the machine from the main before
starting any maintenance procedures.
Tool cleaning procedures.
For a long life of this tool, it must be properly main-
tained and cleaned.
When working with metal, conducting dust may gather
inside the tool. Blow compressed air through the vent
slots 1 to clean this tool regularly. When working with
resinous materials, dust may stick onto some of the tool
parts. For that type of jobs, it will be necessary:
- To verify that the inside of the protective guard 7
is clean.
- To keep the rollers 12 and 15 clean. Their surface must
be clean, and they must rotate freely.
- Check that the dust exhaust outlet 16 is free from
any obstructions.
- Check the vent slots 1, particularly at the lower part
of the tool and remove any obstructions.
Properly clean the above-mentioned components and
remove any obstructions as required.

12. NOISE AND VIBRATION LEVEL
The noise and vibration levels of this device have been
measured in accordance with European standard EN
60745-2-3 and 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
exposure 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 (such as operating times when the machine is
subjected to loads, and operating times when working
with no-load, in effect, not in use, as reducing the
latter may have a considerable effect upon the overall
exposure value).
13. WARRANTY
All VIRUTEX power tools are guaranteed for 12 months
from the date of purchase, excluding any damage which
is a result of incorrect use or of natural wear and tear
on the machine. All repairs should be carried out by the
official VIRUTEX technical assistance service.
