Fuel Filter

Replacing the Fuel Filter
Replace the fuel filter after every 100 operating hours or
yearly, whichever occurs first. The best time to replace the
fuel filter (Fig. 34) is when the fuel tank is empty. Never
install a dirty filter if it is removed from the fuel line.
1. Squeeze the ends of the hose clamps together and slide
them away from the filter (Fig. 34).

Storage

1. For long term storage, either drain gasoline from fuel
tank or add a fuel stabilizer to the gasoline. To drain
gasoline, refer to Draining Gasoline, page 13. After
fuel is drained, start engine and let it idle until all fuel
is consumed and engine stops. Repeat the starting
procedure two more times to ensure all gas is removed
from the engine. If gasoline is not drained, gum-like
varnish deposits will form and cause poor engine
operation, even starting problems.
Note: If engine is operating on oxygenated or
reformulated gasoline (gasoline blended with an alcohol
or an ether), remove all fuel from tank and run engine
until it stops from lack of fuel before storing.
Fuel can be left in gas tank only if a fuel additive, such
as Toro's Stabilizer/Conditioner, is added to gasoline
and run through engine before storing. Toro's
Stabilizer/Conditioner is a petroleum distillate based
conditioner/stabilizer. Toro does not recommend

stabilizers with an alcohol base, such as ethanol,
methanol or isopropyl. Use fuel additive in
recommended quantities as specified on container.
Under normal conditions, fuel additives remain
effective in fuel for 6–8 months.
2. Drain oil: refer to Changing Crankcase Oil, page 14.
After oil is drained, do not fill crankcase with oil until
the following steps (3–11) are completed.
3. Remove spark plug and pour 2 tablespoons of SAE 30
