Priming the Fuel System
Priming the fuel system removes any air bubbles from the
fuel system.
The fuel system would only need to be primed under the
following conditions:
• Before starting the engine for the first time.
• After running the machine out of fuel and fresh fuel has
been added to the fuel tanks.
• After performing maintenance on the fuel system, such
as changing the fuel filter or replacing a fuel system
component.
To prime the fuel system:
1. Make sure that there is fuel in the fuel tanks and that
both fuel tank shut off valves (A, Figure 5) are open (B).
2. Turn the key to the RUN position (not the START
position) for 10 to 15 seconds. The electric fuel pump
feeds fuel to the system.

WARNING
Fuel leaked or spilled onto hot surfaces or electrical
components can cause a fire. To help prevent possible
injury, turn the ignition switch off when changing fuel
filter or water separator element. Clean up fuel spills
immediately.
