Fuel

POTENTIAL HAZARD
Gasoline can vaporize if stored over long
periods of time.
WHAT CAN HAPPEN
Vaporized fuel can explode if it comes into
contact with open flame.
HOW TO AVOID THE HAZARD
Do not store gasoline (fuel) over long
periods of time.
Do not store mower with fuel in the tank in
an enclosure with an open flame. (Example:
furnace or water heater pilot light.)
Allow the engine to cool before storing in
any enclosure.
For long term storage, either drain gasoline from fuel
tank or use a fuel additive before storing. To drain
gasoline, see Draining Gasoline section. 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 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.

Engine

1. While engine is still warm, drain oil from
crankcase. See Maintenance chapter, Change
Engine Oil section.
2. Remove spark plug. Using an oil can, squirt
about one tablespoon of oil through spark plug
hole.
3. Slowly rotate engine several times, using starter
rope, to distribute oil.
4. Reinstall spark plug but DO NOT connect spark
plug wire.

Cleaning

1. Clean mower. See Maintenance chapter,
Cleaning section.
2. Clean dirt and chaff from cylinder, cylinder head
fins, and blower housing. Also remove grass
clippings, dirt, and grime from external parts of
the engine, shrouding, and top of mower
housing.
3. Clean air filter. See Maintenance chapter, Air
Filter section.

General

1. Check condition of blade. See Maintenance
chapter, Blade section.
2. Tighten all nuts, bolts, and screws.
3. Lubricate the wheels. See Maintenance chapter,
Lubrication section.
4. Touch up all rusted or chipped paint surfaces.

Removing From Storage

1. Check and tighten all fasteners.
2. Remove spark plug and spin engine rapidly
using starter to blow excess oil from the
cylinder. Clean spark plug or replace if cracked,
broken or electrodes are worn.
