6.5.3 To examine the fuel system for leakages
1. Connect the adapter to a pressure test tool. Refer to
Servicing tools overview on page 12 .
2. Increase the pressure to approximately 7 psi/0.5 bar.
If the pressure is constant, the fuel system has no
leakage. If the pressure drops, go to the next step.
3. To make sure that the fuel hose does not cause the
leakage, remove the carburetor unit. Seal the fuel
hose by the carburetor and do the pressure test
again. If the fuel hose is not damaged, the
carburetor must be examined.
