moving parts to stop before leaving the operating
position.

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 ensure the fuel
tank drains completely. Then disengage the power take
off (PTO), set the parking brake, and turn the ignition
key to off. Remove the key.
2. Close the fuel shut–off valve (Fig. 46).
3. Loosen the hose clamp at the fuel filter and slide it up
the fuel line away from the fuel filter (Fig. 46).
4. Pull the fuel line off fuel filter (Fig. 46). 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.
5. Install the fuel line onto the fuel filter. Slide the hose
clamp close to the fuel filter to secure the fuel line
(Fig. 46).
