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 assure
fuel tank drains completely. Then disengage
3. Air gap (not to scale)
the power take off (PTO) and turn the ignition
key to off. Remove the key.
2. Close the fuel shut-off valve at the fuel tank
(Figure 26).
3. Squeeze the ends of the hose clamp together
and slide it up the fuel line away from fuel filter
(Figure 27).
4. Pull the fuel line off the fuel filter (Figure 27).
Open the fuel shut-off 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.

Replacing the Fuel Filter

Replace the fuel filter after every 200 operating
hours or yearly, whichever occurs first.
Never install a dirty filter if it is removed from the
fuel line.
Note: Remember how the fuel filter is installed.
Note: Wipe up any spilled fuel.
1. Disengage the PTO, stop the engine, remove
the key, and wait for all moving parts to stop
before leaving the operating position.
2. Close fuel shut-off valve at the fuel tank
(Figure 26).
Note: Remove the fuel line from the fuel
valve that is closest to the engine.
