Notes
7
Charge up the batteries complete-
ly before you use them for the
first time or if you have not used
them for a long time (approx. 24
hours’ timer-controlled charging).
– The charging display lights
up red when charging and
changes to green when it is
fully charged.
7
After the batteries are first char-
ged, the charging time is approx.
12 hours when the appliance is
switched off. If you switch on the
appliance while it is charging,
charging will stop.
– The charging display goes
out.
7
The ambient temperature should
be between 5 °C and 40 °C.

When fully charged, the applian-
ce works for about 40 to 60
minutes.
This depends on the attachment
being used. It is not advisable to
charge the batteries after every
use, especially if you do not use
the appliance for the full 30
minutes.
Charge the batteries at your con-
venience only when they are
completely discharged.
This increases their service life.
Avoid charging every day.
