Use only original high-pressure hoses.
The high-pressure hose and the spray unit must be suitable for use at the maximum operating pressure specified in the technical data.
Avoid contact with chemicals.
Check the high-pressure hose daily. Do not continue using kinked hoses. Do not continue using the high-pressure hose if the outer wire mesh layer is visible.
Do not continue using the high-pressure hose with a damaged thread.
Lay the high-pressure hose in such a way that it cannot be driven over.
A hose that has been driven over, kinked or subjected to impacts may no longer be used, even if no damage is visible.
Store the high-pressure hose in such a way that it is not subjected to any mechanical loads.
The high pressure pump is driven by an intermediate transmission by a diesel engine.
Between the float container and the high-pressure pump, the water is heated via a heat exchanger located in the motor's cooling circuit.
When the jet operation is interrupted, the overflow valve switches to pressure-free water circulation and the motor continues running at idle speed.
The water is heated by a pressure-side burner with oil firing.
During hot water operation, softening agents are added to the water.
HDS 9/50, HDS 13/35 only (optional with HDS 13/20, HDS 17/20): The operating pressure can be selected via the speed control of the motor.
