Replace the Secondary Fuel Filter

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 according to all applicable environmental regulations.
Failure to follow this notice could damage the environment.
1. Prepare the machine for service. See "Maintenance
Safety" on page 2-8.
2. Place a container under the fuel filter (1) to collect
spilled fuel.
3. Remove the fuel filter with a filter wrench.
NOTE: Always use SANY-approved fuel filters.
4. Clean the mounting base of the fuel filter and fill the
new fuel filter with clean fuel. Apply a thin film of 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. Turn the key switch to the ON position for 2-3 minutes before attempting to start the engine. The lift pump will
bleed air from the system.
7. Start the engine and check the fuel filter for leaks.
