IX. Storing Your Engine
A. Short-Term/Seasonal Storage
I. Clean Engine
Before servicing the engine remove the air cleaner cover
and/or blower housing. Discard grass clippings, dirt and
debris from the following areas:
• Cooling Fins
• Air Intake Screen
• Levers
• Linkage
• Guards
• Carburetor
•Head
Removing debris will insure adequate cooling, correct
engine speed and reduce the risk of fire.
II. Fuel Storage
NEVER store engine with fuel in fuel
tank inside a building with potential
sources of ignition such as hot water and space heaters,
clothes dryers, electric motors, etc. Failure to do so may
result in an explosion and result in death or serious injury.
NOTES
If engine fuel stored in the gas tank and/or an approved gas
container is to be unused without gasoline stabilizer for
more than 15-30 days, prepare it for short-term/seasonal
storage. See "IV. Fuel Treatment" instructions.
If engine fuel is to be stored for more than one season,
without gasoline stabilizer, it will gradually deteriorate. Also,
if it is stored in the engine’s gas tank without gasoline
stabilizer it is likely that your carburetor will have gum
deposits, a clogged fuel system and will void your warranty.
Prepare the fuel for extended storage. See "B. Extended
Storage" instructions. Afterward, continue reading
instructions below.
If you operate the engine during all 4 seasons, it is NOT
necessary to lubricate the cylinder bore.
III. Fuel System
To avoid stale gas and carburetor problems, treat the fuel
system in the following method below:
NOTES
Tecumseh recommends using ULTRA-FRESH™ or Fuel
Saver Plus Gasoline Stabilizer plus Fuel System Cleaner as
an acceptable method of minimizing formation of fuel gum
deposits during storage. This product is available from your
Authorized Tecumseh Servicing Dealer.
Always follow mix ratio found on stabilizer container. Failure
to do so may result in equipment damage.
It is NOT necessary to drain stabilized gas from carburetor.
IV. Fuel Treatment
1. Add fuel stabilizer according to manufacturer’s
instructions.
2. Run engine at least 10 minutes after adding stabilizer
to allow it to reach carburetor.
NEVER store the engine with fuel in
the fuel tank inside a building with
potential sources of ignition such as hot water and space
heaters, clothes dryers, electric motors, etc.
NOTE
Instead of using a fuel preservative/stabilizer, you can
empty the fuel tank as described under "I. Draining Fuel"
instructions. See "B. Extended Storage" instructions.
B. Extended Storage
I. Draining Fuel
NOTES
Clean debris from engine before draining fuel from
carburetor. See "I. Clean Engine" instructions. Afterward,
continue reading instructions below.
If you have prepared your fuel for short-term storage it is
NOT necessary to drain fuel that contains stabilizer from
your carburetor. See "A. Short-Term/Seasonal Storage"
instructions.
To avoid severe injury or death,
DO NOT pour fuel from engine or
siphon fuel by mouth.
1. To prevent serious injury from fuel fires, empty fuel tank
by running engine until it stops from lack of fuel. DO
NOT attempt to pour fuel from engine.
2. Run the engine while waiting until the remaining fuel is
consumed.
NEVER leave the engine
unattended when it is running and
NEVER run engine in enclosed areas.
3. Begin servicing the cylinder bore. See "II. Oil Cylinder
Bore" instructions on page 22.
