      The lock locks the lever of the high-pressure gun and prevents the device from starting unintentionally.

      Auto-stop function

      If the lever of the high-pressure gun is released, the pressure switch turns off the pump and the high-pressure jet stops. The pump switches on again when the lever is pressed.

      Motor circuit breaker

      The motor circuit breaker shuts off the device if power consumption it too high.

      Symbols on the device

      Do not aim the high-pressure jet may at persons, animals, live electrical equipment or the device itself.
      Protect the device against frost.
      The device may not be connected to the public drinking water network.

      Intended use

      Use the high-pressure cleaner in private households only.

      The high-pressure cleaner is intended for cleaning machines, vehicles, buildings, tools, façades, terraces, garden machines etc. using a high-pressure water jet.
