Proceed ac- cordingly. Keep both books for future reference or for future owners. Function This scouring and vacuum machine is used for wet cleaning or polishing of level floors. The device can be adjusted to suit the re- spective cleaning task by setting the water volume and detergent volume appropriate- ly. The detergent dosage is adjusted by adding detergent to the tank or via a dosing device ("Dose" option). Brush irrigation is either speed-dependent or constant. 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 has a drive motor. Note The device can be equipped with various ac- cessories to suit the respective cleaning task. Request a copy of our catalogue or visit our In- ternet website at www.kaercher.com. Intended use This device is suitable for commercial and industrial use, e.g. in hotels, schools, hos- pitals, factories, shops, offices, and rental companies. Use the device only in accord- ance with the information in these operat- ing instructions. ● The device may only be used for clean- ing smooth surfaces that are insensitive to water and polishing. ● The device is designed for indoor use. ● The operational temperature range is between +5 °C and +40 °C. ● The device is not suitable for cleaning frozen floors (e.g. in cold stores). ● The device is suitable for a maximum water height of 1 cm.

Initial startup Charging the battery DANGER Inappropriate use of the charger Electric shock Adhere to the mains voltage and fuse val- ues specified on the device type plate. Only use the charger in dry rooms with suf- ficient ventilation. Flammable gases are generated when the battery is charged Risk of explosion Only charge the battery in a suitable room. The room must have a minimum volume depending on the battery type and an ade- quate air exchange rate with a minimum air flow (see "Recommended batteries"). ATTENTION Accumulation of dangerous gases under the tank during the charging process Risk of explosion Pivot the waste water tank upwards before charging low-maintenance batteries. The average charging time is approx. 10- 15 hours. The device cannot be used during the charging process. Note The device has deep discharge protection, i.e. the brush motor and turbine are switched off automatically when the permit- ted minimum capacity level is reached.

1. Drive the device directly to the charger

and do not drive on slopes. External charger ATTENTION Using an unsuitable charger Risk of damage Do not connect the charger to the device- side battery connector.
