Check the washing brushes. Check the washing brushes for damage, soiling and wear. Replace bristles that are
shorter than 30 mm. In winter at temperatures below –5 °C, check for ice formation
and lock the foam wash if necessary. Replace the combination spray lance with a high-
pressure spray lance for this. Operator
Check the information notices at the wash-
ing station. Check that the user information notices are present and legible. Operator
Check the washing station lighting Check the function of the washing station lighting, replace defective lamps. Operator
Check the spray lances Check for tightness, replace the O-ring if necessary. Nozzle protection and grip tube

damage to the system. Operator
Empty the compressor Drain the condensation water from the compressor's pressure tank. Operator
For systems with frost
protection: Daily in the

test set B (order no. 6.768-003). Target value: Less than 3 °dH. Operator
Check residual chlorine content after ac-
tive carbon filter This test is only necessary if the chlorine content in the fresh water is above 0.3 mg/l.
Take a water sample between the active carbon filter and the RO membrane. Deter-
mine the residual chlorine content. If the residual chlorine content of the water sample
exceeds 0.1 mg/l, replace the active carbon filter. Operator
Briefly switch on the washing station heat-
er Activate the frost protection pump as described for "Controller/menu Service". Operator

steel) Treat with stainless steel care product as required. Operator
weekly during frost Check the heating ABS fuel oil tank (op-
tion) Below 3 °C, check whether the trace heating of the fuel oil line between the heating oil
tank and SB MB is warm. Operator
Once, 1 month after
