Practical Hints
Bleeding the Fuel System
A completely bled fuel system is
imperative for perfect engine opera­
tion. During operation, the system is
continuously bled via the overflow
line.
The entire system must be bled
manually after the fuel tank has been
driven completely empty.
First, fill fuel tank with fuel. Then
operate primer pump until the bypass
valve on the injection pump opens
(hissing noise).
Disengage primer pump handle prior
to operating it (turn counterclock­
wise). Retighten after use.
Turning off Engine Manually
If the engine continues operating in
steering lock position “ 0” , open hood
and press lever marked “ STOP” until
the engine stops.
