Proceed accordingly. Keep both books for future reference or for future own- ers. Function This scouring and vacuum machine is used for wet cleaning of level floors. The device can be adjusted to suit the respective clean- ing task by adjusting the water quantity, detergent vol- ume and travel speed. The device can be adapted to the respective cleaning task by selecting a suitable cleaning program. The working width and the capacity of the fresh and waste water tanks (see chapter "Technical data") enable effective cleaning with a long working time. The device is self-propelled. The batteries can be charged using the built-in charger. The charger can be operated with a voltage of 100- 240 V. Note The device can be equipped with various accessories to suit the respective cleaning task. Request a copy of our catalogue or visit our Internet website at www.kaerch- er.com. Intended use This device is suitable for commercial and industrial use, e.g. in hotels, schools, hospitals, factories, shops, offices, and rental companies. Use the device only in accordance with the information in these operating in- structions. ● The device may only be used for cleaning smooth surfaces that are insensitive to water and polishing. ● The device is not suitable for cleaning frozen floors (e.g. in cold stores). ● The device is designed for cleaning indoor floors or covered areas. ● The device is suitable for use in the temperature range 5-40 °C. ● The device must be stored in a frost-free location. ● The device is not suitable for use in potentially ex- plosive environments. ● No flammable gases, undiluted acids or solvents may be taken up with the device. These include pet- rol, paint thinner or heating oil, which can form ex- plosive mixtures in the suction air turbulence. Do not use acetone, undiluted acids or solvents, as these corrode the materials used on the device. ● Reactive metal dusts (e.g. aluminium, magnesium, zinc) in conjunction with highly alkaline or acidic de- tergents form explosive gases. ● The device is not intended for cleaning public traffic routes. ● Take the permissible surface load of the floor into account (see chapter Technical data). ● The device may only be fitted with original accesso- ries and spare parts. ● When using chargers or batteries, only the components approved in the operating instructions may be used. A different combination must be approved by the respon- sible charger supplier and/or battery supplier. Environmental protection The packing materials can be recycled.

DANGER Danger due to the device inadvertently starting up Risk of injury Disconnect the spark plug connector or disconnect the battery before performing any work on the device. ATTENTION Risk of damage to the battery The service life and charging capacity of the battery can be affected by an incorrect charging characteristic. Make sure that the battery characteristic curve that matches the battery is selected in the machine. The currently selected battery characteristic curve can be seen on the display or via the app in the "Device sta- tus" area during charging. Note The charging characteristic can only be adjusted by Kärcher Service. Battery characteristics are available for the following batteries:

● TROJAN 27TMX ● HOPPECKE TB80 ● ZENITH L120185 Note To enable the use of other batteries as well, a custom battery characteristic curve can be created by the Kärcher service department. Charging the battery DANGER Inappropriate use of the charger Electric shock Adhere to the mains voltage and fuse values specified on the device type plate. Only use the charger in dry rooms with sufficient venti- lation. The built-in charger is electronically controlled and suit- able for all recommended batteries, it ends the charging process automatically. Note The corresponding charging characteristic must be set for each type of battery installed. The installed battery is shown in the display when charging. The average charging time is approx. 10-15 hours. The device cannot be used during the charging pro- cess.
