Servicing the Fuel System

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.
Draining the Fuel Tank
1. Park the machine on a level surface to ensure that the
fuel tank drains completely; then disengage the power
take-off (PTO), set the parking brake, and turn the
ignition key to the off position. Remove the key.
2. Close the fuel-shutoff valve at the fuel tank (Figure 31).
3. Squeeze the ends of the hose clamp together and slide
it up the fuel line away from fuel filter (Figure 31).
4. Pull the fuel line off the fuel filter (Figure 31). Open
the fuel-shutoff valve and allow the 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.
5. Install the fuel line onto the fuel filter. Slide the hose
clamp close to the valve to secure the fuel line.
