Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Cleanliness is an important factor. Clean the exterior of the engine thoroughly before the removal procedure. Ensure the area around the Fuel Manifold and the Fuel Lines are thoroughly cleaned. This action will prevent contaminants from entering the internal mechanism. Before replacing any Fuel Lines, follow the instructions that are listed below. Replace the Fuel Lines with the correct Fuel Lines Group.
Turn the fuel supply to the OFF position.
Disconnect the battery.
