Fuel System Priming
If air remains in the fuel inlet line to the engine, it may cause the
engine to run in an abnormal condition. Air may impact the
starting capability of the engine, and may also result in surging
engine speeds.
If the machine happens to have run out of fuel, or if the fuel filter
has been replaced, air may need to be bleed using the following
procedure:
1.
Shut down engine.
2.
Loosen plug (1, Figure 79) on the fuel prefilter head.
3.
Pump the hand operated primer pump (2, Figure 79) on the
fuel prefilter. Pump primer until fuel is present at plug hole
in fuel prefilter head.

Tighten plug (1, Figure 79) in fuel prefilter head.
5.
Continue to pump primer pump until a strong resistance is
felt.
6.
Start engine and look for signs of leaks.
