Features and benefits

Eco!efficiency mode
  • In eco!efficiency mode, the machine operates at the most efficient temperature range (60 °C) – even at the maximum water flow.
  • The burner cycles are optimised to reduce fuel consumption by 20 percent compared to full load operation.
Operational reliability
  • The large, integrated water fine filter provides reliable protection against small dirt particles for the high-pressure pump.
  • The built-in exhaust gas thermostat deactivates the drive motor when the emission temperature exceeds 300 °C.
  • The Soft Damping System (SDS) compensates for vibrations and pressure peaks in the high-pressure system.
Mobility concept
  • Jogger principle with large rubber tyre wheels and steering roller.
  • Sturdy transport eyelets ensure safe transport.
  • Integrated tilting aid for effortlessly negotiating obstacles.
Integrated hose reel
  • Convenient, safe storage of the 20 m high-pressure hose.
  • Extendable and retractable crank handle.
  • Shorter work times.
