only the machine's own weight so that the belt works
at the correct speed determined by the motor at maxi-
mum efficiency. Overworking the machine only gives
rise to a reduction in belt speed which decreases the
working capacity.
The machine is equipped with a dust collector connection
which can be used for connection to our dust collectors
AS182K, AS282K, AS382K or any other industrial equiva-
lent by the optional DUST COLLECTOR ATTACHMENT (ref.
6446073 of 2.25 m or 1746245 of 5 m length).
In the model LB31E/A a built-up dust collector and
collection bag are included.
4. CHANGING THE BELT
Disconnect the machine from the mains
before carrying out this operation.
In order to change the belt pull lever "A" as indicated
in the figure (Fig. 1), remove the used belt and replace
it with another, original VIRUTEX belt, making sure that
the arrows printed on the inside are pointing in the
same direction as arrow "B". To secure the belt, repeat
the above procedure in reverse order.
5. CENTRING THE BELT
To centre the belt (Fig. 2) turn the regulating knob "C"
whilst the machine is running until the belt is centred.
Never allow the belt to rub against the aluminium housing
as it will then no longer be useable (Fig. 3).
Use original VIRUTEX belts (690x100) and fit them so
that they tensioned and centred.

7. MAINTENANCE OF BRUSHES AND COLLECTOR
Disconnect the machine from the mains
before carrying out this operation.
It is important to replace the brushes when they reach
a minimum length of 5 mm (Fig. 5).
Remove the black plugs "G" and take out the brushes
"H" from the guides "I" (Fig. 6). Replace the brushes
with VIRUTEX original spares and ensure that they move
smoothly inside the guides. Replace the enclosing plug.
We recommend that you keep the machine running
for 15 minutes once the brushes have been changed.
If the collector is burned or uneven it should be repaired
by a Virutex service agent.
Always keep the lead and plug in good working condition.
8. NOISE AND VIBRATION LEVEL
The noise and vibration levels of this device have been
measured in accordance with European standard EN
60745-2-4 and EN 60745-1 and serve as a basis for com-
parison 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 expo-
sure 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).
9. 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.
10. RECYCLING ELECTRICAL EQUIPMENT
Never dispose of electrical equipment with domestic
waste. Recycle equipment, accessories and packag-
ing in ways that minimise any adverse effect on the
environment. Comply with the current regulations in
