Draining The Fuel Tank

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. Disengage the PTO
and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Close the fuel shut-off valve at the fuel tank
(Figure 38 ).

6. Pull the fuel line off the filter (Figure 39 ). Open
fuel shut-off valve and allow gasoline to drain into
an approved gas can.
Note: Now is the best time to install a new fuel
filter because the fuel tank is empty.
7. Install the fuel line onto the filter. Slide the hose
clamp close to the filter to secure the fuel line
and filter; Refer to Replacing the Fuel Filter in
Fuel System Maintenance, page 31 .

Servicing the Fuel Filter

Replace the fuel filter after every 100 operating hours
or yearly, whichever occurs first.
