Storage

1. For long term storage, it is recommended that
gasoline be drained from fuel tank or use a fuel
additive before storing. To drain gasoline, refer
to Drain Gasoline, page 14. After fuel is drained,
start engine and let it idle until all fuel is
consumed and engine stops. If gasoline is not
drained, gum–like varnish deposits will form and
cause poor engine operation or even starting
problems.
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
EN–19
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 Change Engine Oil, page 14.
After oil is drained, do not fill crankcase with oil
until the following steps (3–10) are completed.
3. Remove spark plug and pour 30 ml
(2 tablespoons) of SAE 30 oil into hole in
cylinder. Pull starter rope slowly to coat inside of
cylinder. Install spark plug and tighten to
15 ft–lb (20 N m). DO NOT INSTALL WIRE
ON SPARK PLUG.
