Instruction for use - batteries
This cleaner is operated by a Lithium-ion battery. One battery is delivered as standard equipment with the machine. There is an LED-indicator in the upper end of the battery. When the battery is charged and
running at normal power level the LED-indicator is lit with fixed green
light.
When the indicator at the battery starts to flash - less then 30 percent
of the battery power remains. There is also a possibility to order an
extra battery - by doing this the operating time will be extended to approximately 60 min.
There is a push button at the battery. The purpose of this button is to
show the remaining power of the battery if the battery is stored outside
the cleaner. Push the button down and the capacity of the battery will
be shown at the LED-indicator for 30 seconds. When the indicator at
the battery starts to flash - less then 30 percent of the battery power
remains, and it will soon need to be charged. Note! In order to save
power, these batteries will be set in a storage mode if not been used
within a period of 4-8 weeks. If this occurs please push the reset button
at the battery.
Instruction for use - charger
The charger should be placed at a table, shelf or be mounted on a wall.
If it is mounted on a wall - choose screws and if necessary, wall plugs
to suit the charger to the material of the wall.
When the LED-indicator at the batteries starts to flash, there is less
than 30 percent of the battery power remaining. The battery will run
normally until 0% then it switches itself off. Do the following to charge
the batteries:
1. Connect the main cord of the charger to the charger.
2. Attach the battery to the charger.
3. Pull the battery backwards to the outlet of the charger.
4. Plug in the other end of the main cord to an electrical wall outlet.
The batteries will be charged automatically. The LED indicator at the
battery flashes green to indicate that the battery is being charged.
When the battery is fully charged, the LED indicator at the battery will
be lit with fixed green light.
Two batteries will be fully charged within 100 minutes. The charged battery can remain on the charger until it is to be used. There is no risk of
over-charging.
