• Children shall not play with the appliance.
• Cleaning and user maintenance shall not be made by children
without supervision.
• The appliance is intended for use with safety extra-low voltage.
Connect only to a power supply according to the specifications on
the rating label.
• If the connection cable of this appliance has been damaged, it
must be replaced with a special connection cable available from
the manufacturer or its customer service.
• Do not use any power adapter other than the one supplied.
• Do not suck in combustible substances or liquids!
• Do not suck up hot ashes or pointed or sharp objects!
• Never vacuum without the filter installed.

Rechargeable Lithium-Ion Batteries (Li-Ion)

The appliance is equipped with rechargeable Li-ion batter-
ies. This results in numerous advantages compared to other
batteries and accumulators:
• A high cell voltage (more volts)
• No memory effect
• A low self-discharge

Safe Handling of Rechargeable Lithium-Ion Batteries

In general, Li-ion batteries are considered safe. Never-
theless, hazards may result from mechanical damage,
electrical faults and thermal effects.
Mechanical damage may result in the leakage of gaseous
or liquid substances that can be highly irritating, flammable
or even toxic.
An electrical fault, such as a short circuit, may lead to over-
heating and cause a fire.
Even the heating of the outer shell of a Li-ion battery, e. g.
due to sunlight or a heating element, may lead to fire or an
explosion.
However, Li-ion batteries are safe when handled properly.
Only if used or stored improperly they may become danger-
ous. Therefore:
• Avoid temperatures above 40 °C and below 0 °C.
• Do not drop the appliance or the rechargeable battery.
• In case the Li-Ion battery has been dropped and is now
damaged, stop using it.

• When storing or disposing of the appliance, mask the
terminals to prevent short circuits.
• Dispose of old accumulators properly in collecting con-
tainers at the trader or at municipal collection points.

Extending the Life of the Rechargeable Li-Ion Battery

For Li-ion batteries, even more than with other accumula-
tors, their life can be extended by treating them properly.
The following simple rules for charging and storing help you
keeping the capacity of the battery:
• Temperature: The ideal temperature for these batteries
ranges from 10 - 25 °C. Temperatures above may lead to
premature aging.
• Charging and discharging: During charging cycles,
both full charge and deep discharge should be avoided.
When the charging process of the battery is completed,
you should disconnect the charger immediately. A charge
up to 90 % is considered best.
Conversely, it is also preserving the battery more when
it is not discharged to 0 %. If the possibility arises, you
should already recharge the battery when it is reaching a
charge state of 30 %.
• Storage: Always store batteries in a dry place and at
moderate temperatures between 10 °C and 20 °C.
Also consider the effect of self-discharge! When the
accumulator is already empty, this effect may lead to
a deep discharge resulting in damaging the battery. If
you intend to store the battery for an extended period of
time, you can counteract this effect. We then recommend
charging the battery to approx. 40 % before storage. You
