WARNING!
may spray from the spark plug hole. To prevent
serious injury from fuel fires, follow these
instructions:
1. Carefully disconnect the spark plug wire and keep it away
from the spark plug.
• Keep the disconnected spark plug wire securely
away from the metal parts where arcing could
occur.
• Carefully attach the spark plug wire to the
grounding post, if provided.
• Disconnect the battery at the negative terminal first, if the
engine is equipped with a D.C. electric starter.
• Turn off all the engine switches.
• Remove the ignition key, if provided.
2. Remove the spark plug.
3. Squirt 1oz. (30ml) of clean engine oil into the spark plug
hole.
4. Cover the spark plug hole with a rag to prevent fuel from
spraying from the spark plug hole when the starter rope is
pulled.
NOTE: for engines equipped with a recoil starter, proceed
to Step 5. For engines equipped with electric starters,
proceed to Step 6.
5. Grasp the starter cord handle:
• Pull the starter cord handle out slowly using a
full arm stroke.
• Repeat once. This will distribute the oil
throughout the cylinder to prevent corrosion
during storage.
• Proceed to Step 7.
6. Push starter button or turn ignition switch key to "START":
position. Immediately releases the starter button or turn
the ignition switch key to the "OFF" position. This will
distribute the oil throughout the cylinder to prevent
corrosion during storage.
7. Remove the rag from the spark plug hole.
8. Install the spark plug.
9. Carefully disconnect the spark plug wire from the
grounding post, if provided.
10. Connect the spark plug wire plug wire to the spark plug.

Off-Season Storage

CAUTION:
Failure to use a fuel stabilizing additive
or completely run the engine until it's out of fuel
before off-season storage may result in damage to
your engine's carburetor. Subsequent damage
would not be covered under the manufacturer's
warranty.
Engines stored between 30 and 90 days need to be treated with
a gasoline stabilizer and engines stored over 90 days need to be
drained of fuel to prevent deterioration and gum from forming
in fuel system or on essential carburetor parts. If the gasoline in
your engine deteriorates during storage, you may need to have
the carburetor, and other fuel system components, serviced or
replaced.
1. Remove all fuel from tank by running engine until it stops
from lack of fuel.
WARNING!
Never leave engine unattended while it
is running.
2. Change the oil. See Changing the Oil earlier in this section.
3. Remove the spark plug and pour approximately a
of engine oil into the cylinder. Replace spark plug and
crank it slowly to distribute oil.
4. Clean debris from around the engine and the muffler.
Touch up any damaged paint, and coat other areas that
may rust with a light film of oil.
5. Store in a clean, dry and well ventilated area away from any
appliance that operates with a flame or pilot light, such
as a furnace, water heater, or clothes dryer. Also avoid any
area with a spark producing electric motor, or where power
tools are operated.
6. If possible, also avoid storage areas with high humidity,
because that promotes rust and corrosion.
7. Keep the engine level in storage. Tilting can cause fuel or
oil leakage.
