Servicing the Fuel Tank

In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
• Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open
area. Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and
stay away from an open flame or where a
spark may ignite the gasoline fumes.
1. Park the machine on a level surface to ensure that
the fuel tanks drain completely.
2. Disengage the power takeoff (PTO), set the parking
brake, stop the engine, and remove the key.
3. Close the fuel shutoff valve (Figure 39).
4. Loosen the hose clamp at the fuel filter and slide it
up the fuel line away from the fuel filter (Figure 39).
5. Disconnect the fuel line from the fuel filter
(Figure 39).
6. Open the fuel shutoff valve.
Note: Allow gasoline to drain into a fuel container
can or drain pan (Figure 39).
Note: Now is the best time to install a new fuel
filter because the fuel tank is empty.
7. Install the fuel line onto the fuel filter. Slide the hose
clamp close to the fuel filter to secure the fuel line
(Figure 39).
