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 result in damage to the environment.
NOTE: Use diesel fuel to clean the inside of the fuel tank.
Never use trichloroethane to clean the fuel tank.
1. Prepare the machine for service. See “Maintenance
Safety” on page 2-5.
NOTE: For fuel tank capacity, see “Fluid Capacities” on
page 5-8.

3. Follow the drain hose (2) from the drain valve (1) to
where it exits the bottom of the machine. Place an
appropriate container under the drain hose.
4. Open the drain valve to drain water and sediment
accumulated on the bottom of the tank. Do not allow
any fuel to splash out of the container.
5. When only clean fuel drains from the fuel tank, close
the drain valve.
6. If the fuel tank is completely drained, the system
must be bled after refilling. See “Bleed the Fuel
System” on page 5-26.
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.

2. Place a container under the fuel filter (1) to collect
any 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 fuel
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 5-26.
7. Start the engine and check the fuel filter for leaks.
