Pressure washer HD 7/16-4 St
The configurable HD 7/16-4 ST, with a working pressure of 160 bar, is the starting version in the area of stationary high-pressure cleaners with single-lance operation
The 7/16-4 ST is an entry-level model in the range of stationary cold water high-pressure cleaners from Kärcher. With a working pressure of 160 bar, it also impressively handles difficult cleaning tasks. But in particular it shines with its large range of (in part retrofitted) configurable equipment details. For example, the machine is also available as a hot water version. Also options such as pressure relief, dry-running protection, stainless steel housing, water softening or elapsed time counter are available. In addition there is the option of drawing in 1 or 2 cleaning agents at high or low pressure, and also, thanks to the extensive range of accessories, of optimally adapting the machine to its place of use. New developments that increase operating comfort, such as the EASY!Force high-pressure gun, which 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, are standard features.

Configurable components
Configurable components
After the timer function has turned off the device, the high-pressure unit is still under pressure. The kit reduces system pressure, thereby protecting the pressurised components. The pressure relief kit is recommended especially if lengthy pauses occur between the individual usage intervals.
The kit prevents calcification in the system through continuous injection of water softener. Damage to the pump and other important components due to calcification can be prevented in this way. Especially recommended for high feed temperatures and the ST-H version.
The device operating time can be precisely determined with the "operating hour counter" kit. Ideal for high usage frequency – for service interval optimisation.
The kit enables the control of cleaning agent injection by remote control directly at the supply point. The low-pressure application is especially economical. No additional cleaning metering pumps are required. Minimal aerosol formation (spray) occurs during use. The "remote control preparation" is recommended especially for supply points which are repeatedly used by the same persons and for cleaning tasks which can be performed in the low-pressure range.

No additional cleaning metering pumps are required. Minimal aerosol formation (spray) occurs during use. The "remote control preparation" kit is recommended especially for supply points which are repeatedly used by the same persons and for cleaning tasks which can be performed in the low-pressure range. The variant with two cleaning agents is suitable, for example, for more complex cleaning tasks, distant supply points or for car cleaning.
The kit enables the control of cleaning agent injection by remote control directly at the supply point. The advantage compared with the low-pressure variant lies in the fact that no changing of the nozzle is necessary to apply the cleaning agent. The "remote control preparation" is recommended especially for supply points with frequently changing users, since no changeover at the nozzle which needs an explanation is required here, for operation by coin remote control and for cleaning tasks which require high pressure.
