Remove screws D (Fig. 4) that fasten the side covers
E and detach both.
Remove the brush-holder G (Fig. 5) with small
screwdriver F, using one of the brush-holder side
tabs to lever it out.
Push back the end of spring H. Keep it in this posi-
tion to extract the brush and replace it with a new
genuine Virutex brush. Reinsert the brush-holder,
ensuring that it is firmly positioned in the casing
and that each of the brushes exerts a small amount
of pressure on the collector.
Re-attach the covers E with the corresponding screws,
making sure that no wires get caught in the process.
It is advisable to leave the machine running for 15
minutes once the brushes have been changed. If the
collector burns or juts out, it should be serviced by
a Virutex service technician.
Keep the lead and plug in good working condition.

been measured in accordance with European stan-
dard 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,
Disconnect the machine from the
mains before carrying out any kind of
maintenance work.
