Servicing the Fuel Tank
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 assure fuel tank
drains completely. Then disengage the blade control
(PTO) and set the parking brake.
2. Close the fuel shut–off valve in fuel line (Fig. 43).
3. Squeeze the ends of the hose clamp together and slide it
up the fuel line away from fuel filter (Fig. 43).
4. Pull the fuel line off the fuel filter (Fig. 43). Open fuel
shut-off valve and allow gasoline to drain into a gas can
or drain pan.
Note: Now is the best time to install a new fuel filter
because the fuel tank is empty. Refer to Replacing the Fuel
Filter; page 31.
5. Install the fuel line onto the fuel filter. Slide the hose
clamp close to the filter to secure the fuel line.
