Burst disc If the working pressure exceeds the max. permissible overpressure by approx. 10%, the burst disc will be destroyed and the water will circulate inside the appliance without pressure. High pressure operation no longer possible. Pressure switch The pressure switch switches off the appliance if the minimum prepressure is not reached. High pressure sensor The pressure sensor monitors the pressure buildup in the high pressure system.

Operation Please observe Chapter "Safety Instructions" and the enclosed safety instructions for high pressure cleaners (5.063-314.0) Î Remove the chocks from underneath the wheels and place them in their holders. Î Release parking brake. Transport Trailer operation Note The driver, who operates the towing vehicle with trailer on public roads must ensure that he has the appropriate license for this.
Caution Do not completely deplete the fuel in the fuel tank, otherwise, the fuel system will have to be ventilated. Possibly suctioned dirt from the bottom of the tank can lead to malfunctions. Î Check the fill level of the diesel fuel at the bar segment display for the fuel level. If required, top off the diesel fuel. For temperatures below 0°, only use winter diesel. Check the fill level in the water tank Î Check the fill level of the water at the bar segment display for the water level in the tank.
Î Connect the water supply hose to the respective water inlet (arrow). Î Open the lock on the appliance cover and swivel the appliance cover upwards. Î Swivel the latch of the appliance hood upwards to keep it from shutting inadvertently. Î Check the water filter for contamination, clean/replace if required. Î Switch off the motor. Î Install the nozzle as described in the chapter "Connecting the nozzle". Settings + 8 7 The control voltage is switch on and the display shows the operating status.
Î By pressing the F6 key twice, you will return to the operating display. 0 ___ 155 ___ 210 Î Step 3: Press the F3 key to switch between brightness and contrast. Î You can change the brightness and contrast levels with the F4 and F5 keys. F4 (-) = set value decreases. F5 (+) = set value increases. Î By pressing the F6 key twice, you will return to the operating display.
Î Refill the antifreeze container with antifreeze. Select the mixing ratio of the water/antifreeze as per the instructions of the antifreeze manufacturer. Î Align the actuation lever of the ball tap for antifreeze/water tank vertically. Î Unscrew the high pressure hose from the high pressure outlet. The control voltage is switched on and the display shows the antifreeze rinse operation. Î Press the F2 key to start the motor. Î Let the motor run until antifreeze is visible in the antifreeze hose.
