HD 7/14-4 M high-pressure cleaner comes with numerous innovative equipment features as standard for safe and comfortable working. The automatic pressure relief feature protects high-pressure components from loads in stand-by mode, for example, while the innovative EASY!Force high-pressure gun utilises the recoil force of the high-pressure jet to reduce the retaining force to zero, and the EASY!Lock quick-release couplings enable handling that is five times faster than conventional screw connections, without compromising on robustness or longevity. The machine is suitable for vertical or horizontal operation and thus offers a great deal of flexibility in use. The robust 3-piston axial pump with brass cylinder head increases cleaning power and energy efficiency by around 20%.
