Before start-up
Inspect power cord regularly
to detect signs of damage, e.g.
cracks or ageing.
If the power cord is damaged, it
must be replaced by the Service
or an electrician to avoid danger
before use of the vacuum clean-
er is continued.
Use only the type of power cord
specified in the operating man-
ual.
Do not damage the power cord
(e.g. by moving over it or pulling
or crushing it).
Disconnect the power cord by
pulling the plug only (do not pull
or tug the power cord).
Inspect the vacuum cleaners to
ensure that they are in proper
condition. Plugs and couplings
in power cords must at least
have splash protection.
Never use the vacuum cleaner if
the filter element is damaged.
Picking up liquids
If foam develops or liquid emerg-
es, stop work immediately and
empty the dirt tank.
Regularly clean the built in float
to limit the water level and check
that they are not damaged.
See section 5 for information on
handling liquids and (hazard-
ous) dust.
Electrical components
Check the rated voltage of the
vacuum cleaner before connect-
ing it to the mains supply system.
Ensure that the voltage shown
on the rating plate corresponds
to the voltage of the local mains
power supply.
If you are using an extension
cord, use only those specified
by the manufacturer or higher
quality ones (see section 9.4
„Technical data“).
It is recommended that the vac-
uum cleaner should be connect-
ed via a residual current circuit
breaker. This stops the supply
of electricity if the leakage cur-
rent to earth exceeds 30 mA for
30 ms or it has an earth tester
circuit.
When using an extension lead,
check the minimum cross-sec-
tions of the cable:
Cable length
m Cross section
<16 A <25 A
up to 20 m ø1.5mm² ø2.5mm²
20 to 50 m ø2.5mm² ø4.0mm²
Arrange the electrical parts
(sockets, plugs and couplings)
and lay down the extension lead
so that the protection class is
maintained.
Never spray water on to the up-
per section of the vacuum clean-
er. Danger for persons, risk or
short-circuiting.
Observe the latest edition of the
IEC regulations.
– risks associated with the ma-
terial to be picked up
– safe disposal of the picked
up material.
