Draining the Fuel Tank

Drain the fuel tank when you will not be using the
machine for more than 30 days.
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 so that the left front side is slightly
lower than the right side to ensure that the fuel tank
drains completely.
2. Disengage the blades (PTO).
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. Close the fuel shut-off valve located under the front
of the fuel tank.
7. Loosen the hose clamp at the fuel filter and slide it
up the fuel line away from the fuel filter (Figure 27).
