VIII. Transporting Your Engine

NEVER transport this engine inside

another vehicle or in any enclosed

space if there is any gasoline in the tank. Fuel vapor or

spilled fuel may ignite leading to serious injury or death.

If there is fuel in the fuel tank, close the fuel shut-off valve,

if equipped, and transport the engine upright in an open

vehicle, such as an open trailer or open bed of a pickup

truck.

If you DO NOT have an open vehicle and have to transport

the engine upright in a closed vehicle, follow these steps

for emptying the fuel tank before transporting:

1.

Empty fuel tank by using a commercially available

suction device designed for use with gasoline.

To avoid serious injury or death, DO

NOT pour fuel from engine or siphon

fuel by mouth.

2.

Drain fuel into an approved red GASOLINE container,

being careful to avoid spilling.

3.

Run the engine until remaining fuel is consumed.

NEVER leave the engine unattended

when it is running and NEVER run

engine in enclosed areas to avoid death or serious injury.

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. Remove 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 the

fuel tank inside a building with

potential sources of ignition such as hot water or space

heaters, clothes dryers, electric motors, etc. Doing so may

lead to an explosion resulting 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. Afterward,

continue reading instructions below.

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 on page 13. Afterward,

continue reading instructions below.

III.

Fuel System

To avoid stale gas and carburetor problems, treat the fuel

system in the following method below:

NOTES

TecumsehPower Company recommends using

ULTRA-FRESH

™

Gasoline Stabilizer as an acceptable

method of minimizing formation of fuel gum deposits during

storage. This product is available from your Authorized

TecumsehPower 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 engine with fuel in the

fuel tank inside a building with

potential sources of ignition such as hot water or space

heaters, clothes dryers, electric motors, etc. Doing so may

lead to an explosion resulting in death or serious injury.

NOTE

Instead of using a fuel preservative/stabilizer, you can

empty the fuel tank as described under "I. Draining Fuel"

instructions on page 13. See "B. Extended Storage"

instructions.
