Features and benefits
 HDS 10/20-4 M Classic: Efficiency
In eco!efficiency mode, the machine operates at the most efficienttemperature 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.
 HDS 10/20-4 M Classic: Maximum efficiency
Maximum efficiency
Highly efficient, tried-and-tested burner technology. 4-pole electric motor with three-piston axial pump. Water-cooled motor for a high level of performance and durability.
 HDS 10/20-4 M Classic: Operational safety
Operational safety
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.
  • Safe and ample storage for protective gear, accessories and cleaning agents.
  • Storage hooks for power cord and high-pressure hose.
Mobility concept
  • Jogger principle with large rubber tyre wheels and steering roller.
  • Integrated tilting aid for effortlessly negotiating obstacles.
Save energy and time: EASY!Force high-pressure guns and EASY!Lock quick-release locks.
  • At last – work without getting tired: the EASY!Force high-pressure gun.
  • EASY!Lock quick-release locks: durable and robust. And five times faster than screws.
