Replace the Secondary Fuel Filter
1. Prepare the machine for service. See “Maintenance
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.
