10.1.1 Cleaning the vehicle
Cleaning
During the first four weeks, clean the trailer only with clear water and do not use a high-pressure cleaner. If the trailer is
delivered in winter, it must be washed immediately after it is received to remove any road salt that has collected on the
trailer.
Note the following rules for upkeep of the trailer:
-
Wash the trailer only with clear water without any cleaning additives to prevent paint damage. Repair any paint
damage immediately.
-
When cleaning with a high-pressure cleaner, maintain a distance of at least 400 mm with the spray nozzle.
-
The water temperature must not exceed 60° when cleaning.
-
Clean the trailer after every use in winter to prevent damage from road salt.
-
Clean impurities out of the dirt traps regularly. This can be done with a high-pressure cleaner.
Note the following rules for cleaning and maintaining the electrical connections:
As a rule, electrical connections must not be cleaned with water or mechanical objects. We recommend that you use
compressed air at 6 to 8 bar in combination with an air blow gun.
Check the oil level on the compressor, top up if necessary
