Burst disc

If the working pressure exceeds the max. permissible overpressure by approx. 10%, the burst disc will be destroyed and the wa- ter will circulate inside the appliance with- out pressure. High pressure operation no longer possible.

Pressure switch

The pressure switch switches off the appli- ance if the minimum prepressure is not reached.

High pressure sensor

The pressure sensor monitors the pressure buildup in the high pressure system. If the pressure sensor detects an exceedingly rapid pressure decrease, as might be the case with leaks or a burst hose, as well as if the working pressure is exceeded, the ap- pliance will shut off.

Warning and instructive signs

￿Danger

Risk of injury on account of electric shock!

￿Warning

Risk of burns on account of hot surfaces!

￿Warning

Danger of crushing. Do not remove the cover while the appliance is running.

Do not reach near the cooling fan and the V- belt while the motor is running.

ÎRetighten the wheel bolts and the wheel nuts after driving 50 km to a torque of 100 Nm.

ÎRepeat the check af- ter 500 km have been driven and after 50 operating hours.

ÎRepeat the safety checks at regular in- tervals.

ÎHave the brake sys- tem and the lighting system checked reg- ularly by an author- ised dealer workshop.

Keep the warning and instructive signs on the appliance clean.

Replace damaged or missing warning and instructive signs with new ones.

Furthermore, the personnel must partici- pate in a Kärcher safety seminar.

Function

The high pressure pump is driven by an in- termediate gear by a diesel motor.

When the jet operation is interrupted, an electric signal will switch the system from hand spray gun to pressureless water cir- culation.

The preset operating pressure is regulated via the motor speed.
