- Thoroughly clean the connection areas and areas near these connections before disconnecting the parts.
- Place the removed parts on a clean base and cover with film or paper. Do not use lint-free cloths for this purpose!
- Exposed parts should be carefully covered or sealed unless urgent repairs are being performed.
- Install only clean parts.
- Remove spare parts from the packaging only immediately before installation.
- Do not use parts that have been stored unpacked (for example, in a toolbox, etc.)
- If possible, do not work with compressed air when the supply system is open. If possible, do not move the vehicle.
- Do not allow diesel fuel to get into the engine cooling system hoses, as this will cause them to age quickly. Wipe off any spilled diesel fuel immediately with a damp cloth.
