Clean Working Conditions






Clean Working Conditions

When working on the fuel supply/injection system, pay careful attention to the following "5 rules" of cleanliness:

Always clean the connection locations and the areas around them before loosening.

Place removed parts on a clean surface and cover them using lint free cloths.

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

Only install clean components: Remove the replacement parts from their packaging just prior to installing them. Do not use parts that have been stored loose (for example, in a tool box, etc.).

When the system is open: Avoid working with compressed air if possible. Do not move the vehicle unless absolutely necessary.
