2. Place removed components on a clean surface and cover. Use plastic sheeting or paper. Do not use fluffy rags that could leave lint!

4. Install only clean parts:
Do not remove replacement parts from the packaging until immediately before they are to be installed.
Do not use parts that have been stored without packaging (e.g. in toolboxes, etc.).

Avoid working with compressed air whenever possible.
Avoid moving the vehicle if possible.
