Care and maintenance

Observe the instructions in the section entitled "Safety".
Before long-term storage:
Fully charge the lithium-ion battery [9] before long-term storage. The time intervals be-
tween subsequent charging cycles must not be longer than 12 months.

If the battery is not used for 14 days, the charge will automatically go down to 30%
and thus the preconditions for storage are fulfilled. In the course of this the battery
heats up. The charge level indicator has no indication then. Connect the battery to
the charger for some seconds to reactivate the battery. Please observe in addition
the "important instructions" enclosed with the rechargeable battery.
After using the device 50 times or if the device malfunctions, at least once a year:
1. Clean the nozzle [25] and the associated filter [26] under running water. If required use
a brush (Fig. 14).
2. Clean the filter [27] of the suction hose [3] under running water. If required use a brush
(Fig. 14).
3. Clean the aeration valve [28] in the tank cap [2] under running water. If required use a
brush (Fig. 14).
Observe the legal requirements of your country for accident prevention and check
the device in regular intervals.
If there are no special rules, we recommend you have the device examined by a
competent professional every 2 years. We would be happy to provide you with an
inspection schedule in German or English.
