288 Cleaning and care Examples of dirt-intensive operating condi- tions or environments: G WARNING The water jet from a round-jet nozzle (dirt grinder) can cause damage to tyres, suspen- sion components or air bellows that is not visible from the outside. Components that have been damaged in this way can unex- pectedly fail. There is a risk of an accident. Do not use a high-pressure cleaner with a round-jet nozzle to clean your vehicle. Have damaged tyres, suspension components or air bellows replaced immediately. High-pressure cleaning R Pesticide and fertiliser spreading:
plant matter which touches, brushes against or gathers in the chassis or vehicle body, such as cereal ears R Harvesting green fodder or maintenance of road verges, such as mowing, mulching, pressing or loading: deposits of dust, grass, cuttings or hay in the chassis or body R Harvesting or landscape maintenance, such as pressing, loading or wood chop- ping: deposits of dust, straw, corn or cut- tings in the chassis or body Maintenance and care ! Never use a high-pressure cleaner in the vehicle interior. The pressurised water cre- ated by the high-pressure cleaner and the associated spray could cause considerable damage to the vehicle. R Waste disposal vehicles:
deposits of flam- mable waste in the chassis, such as paper R Disaster relief work and fire-fighting in for- ests and on open plains: deposits such as grass, plant material and undergrowth ! The BlueTec ® exhaust gas aftertreatment system may only be cleaned when it is cool. The sensors could otherwise be damaged. When cleaning, make sure never to point the water jet at the exhaust pipe. The exhaust gas aftertreatment could other- wise be damaged. Access steps ! When using a high-pressure cleaner, keep a minimum distance between the high- pressure nozzle and the vehicle parts. Parts of the vehicle or engine can otherwise be damaged. Observe the following minimum distances:
Keep steps ; and grab handles : free from dirt such as: R Round spray jet approximately 70 cm R mud R 25°flat-spray jet approximately 30 cm R clay !
