1. Twist off the cap of the fuel scavenging valve -1-.
NOTE: Proceed as follows to fit the adapter 1318/20 -2- to the scavenging valve: Turn the valve -4- anti-clockwise at the T-piece until the valve
is closed. Place the adapter on the scavenging valve and use the knurled nut -3- to fit the adapter in a clockwise direction until the adapter is
attached securely to the scavenging valve. To open the scavenging valve, turn the T-piece of the valve clockwise (the fuel is released immediately
and flows out via the adapter 1318/20). If the T-piece touches the intake-air distributor when you turn it, shorten the cross-pin of the T-piece
slightly so that it has sufficient clearance. The adapter 1318/20 includes a hose connection 1318/20-1 -1-, to which a suitable fuel hose can be
fitted using a screw-type clamp.
