Replace the Secondary Fuel Filter
1. Prepare the machine for service. See “Maintenance
Safety” on page 2-9.
2. Open the engine hood. Place a container under the
secondary fuel filter (1) to collect spilled fuel.
3. Remove the fuel filter with a filter wrench.
4. Clean the mounting base of the fuel filter and fill the
new fuel filter with clean fuel. Apply a thin film of
engine oil to the O-ring and install the new fuel filter
onto the filter housing.
5. When the fuel filter O-ring touches the filter housing,
turn the fuel filter an additional 1/2 turn. Overtightening
the filter may damage the O-ring, resulting in a fuel leak.
6. Bleed trapped air from the fuel system. See “Bleed the
Fuel System” on page 5-30.
7. Start the engine and check the fuel filter for leaks.
WARNING!
• Components and oil remain hot when the engine is stopped, which may cause severe
burns. Wait until components and oil are cool before you proceed.
• Never service the fuel system near an open flame or while smoking.
• Fuel that comes into contact with hot surfaces or electrical components can cause a fire.
Clean up any fuel spills immediately.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
• Cleanliness is important when working with an open fuel system. Contaminated fuel can
result in engine damage.
• Dispose of fuel and filter in accordance with all applicable environmental regulations.
Failure to do so could damage the environment.
