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, fuel and fuel vapors are
extremely flammable and highly explosive. A
fire or explosion from fuel can burn you and
others and can damage property.
• Drain fuel from the fuel tank when the
engine is cold. Do this outdoors in an open
area. Wipe up any fuel that spills.
• Never smoke when draining fuel, and stay
away from an open flame or where a spark
may ignite the fuel 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. Open the hood.
7. Squeeze the ends of the hose clamp together
and slide it up the fuel line toward the fuel tank
(Figure 30).

to secure both the fuel line and the fuel filter
(Figure 30).
