Note
Maintenance work that is not carried out on time and in
a professional manner will result in the loss of the war-
ranty in the event of frost damage.
Performed
Remove and clean the filter (see "Cleaning the Power foam nozzle filter"). Determine
the following cleaning intervals according to experience.
Check the washing brushes for dirt and ice and lock the washing brush if necessary. Operator
Clean the filter and insert it again.
Are the hot air blowers in operation (also with ABS fuel tank, option)?
Check the function.
Is the heating oil supply sufficient until the next inspection? Take into account in-
creased consumption due to frost protection devices. Lack of fuel leads to failure and
damage to the system.
Below 3 °C, check whether the trace heating of the fuel oil line between the heating oil
tank and SB MB is warm.
Target value: approx. 0.5 l/min per washing tool.
Water volume greater: Replace the node piece in the high-pressure gun.
WARNING
Risk of injury, risk of damage
The high-pressure gun can move uncontrollably and cause injuries or damage if the
frost protection water volume is too high.
Be sure to replace the node piece in the high-pressure gun if the frost protection water
quantity is too high.
Water quantity smaller: Clean the frost protection pump filter, clean the sieve in the
throttle, flush the pipe, check the direction of rotation of the pump.

3. Refill the fuel tank.
Shutting down
If there is no danger of frost during the shutdown period:
1. Shut off the water inlet.
2. Disconnect the power supply.
Shutting down during frost
If there is a risk of frost when shutting down, the follow-
ing additional steps must be carried out.
1. Unscrew the water supply hose and the high-pres-
sure hose.
2. Remove the RO membrane and store it frost-free.
3. Empty all float tanks, remove the hoses and drain
the water.
4. Empty the permeate buffer tank.
5. Disconnect the water pipe between the base ex-
changer and the hot water float tank.
6. Flush the system (without base exchanger) with
frost protection solution.
7. Rinse the base exchanger with concentrated salt
solution.
8. Unscrew both hoses under the flow-through kettle
and let the water drain off.
9. Blow out all water-bearing parts with oil-free com-
pressed air.

Note
During longer breaks in operation, the system, with the
exception of the base exchanger, must be rinsed with
frost protection solution to protect it from corrosion
