Installation and commissioning
NOTE!
The engine has a self-venting fuel system. In the
case of the tank running empty, faultless operation
after refilling is ensured by the self-venting.
The venting can be accelerated by operating the
lever (1) on the fuel feed pump (2).
5. Using the lever (1) on the fuel feed pump (2), pump by hand
until the counterpressure becomes noticeable.
This builds up the primary pressure in the fuel system and
accelerates the venting.
