Draining the Fuel Tank

Danger
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 PTO, move the motion control levers to
the neutral locked position and set the parking brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Close the fuel shut-off valve (Fig. 35).
5. Loosen the hose clamp at the fuel filter and slide it up
the fuel line away from the fuel filter (Fig. 35).
6. Pull the fuel line off of the fuel filter (Fig. 35).
7. Open the fuel shut-off valve for the left and right tanks.
Allow gasoline to drain into a gas can or drain pan
(Fig. 35).
Note: Now is the best time to install a new fuel filter
because the fuel tank is empty.
8. Install the fuel line onto the fuel filter. Slide the hose
clamp close to the fuel filter to secure the fuel line
(Fig. 35).
