Clean Working Conditions






Clean Working Conditions

Always clean connection places and surrounding areas with engine or brake cleaner before loosening and try cleaned places.

Immediately seal open lines and connections with clean plugs or protective caps.

Place removed parts on a clean surface and cover. Only use lint-free cloths for this!

Carefully cover or plug unpacked components if repairs cannot be performed immediately.

Only install clean parts: Remove packing from replacement parts immediately prior to installation and not before.

Protect disconnect electrical connectors from dirt and moisture and only connect when they are dry.
