D.

Filling Fuel Tank

An adult should fuel this engine.

NEVER allow children to refuel this

engine. Gasoline (fuel) vapors are highly flammable and

can explode. Fuel vapors can spread and be ignited by a

spark or flame many feet away from engine. To prevent

injury or death from fuel fires, follow these instructions:

1.

Stop engine and allow it to cool before refueling.

2.

Be sure engine is outdoors and in a well-ventilated

area.

3.

Clean area around fuel fill cap and remove fuel fill cap.

See Figure 8.

4.

Using an approved red GASOLINE container, add fuel

slowly, being careful to avoid spilling. DO NOT overfill

fuel tank. Leave space in the tank to allow fuel to

expand without overflowing.

5.

Replace anti-splash fuel fill cap securely and wipe up

spilled fuel before starting engine. If fuel is spilled DO

NOT start engine. Move machine away from area of

spillage. Avoid creating any source of ignition until fuel

vapors are gone.

NOTES

Remove and discard white plastic fuel tank insert, if

provided. See Figure 10.

Replace a damaged or missing gas cap only with a genuine

Tecumseh replacement anti-splash fuel fill cap. Failure to do

so may VOID YOUR WARRANTY. See Figure 11.

6.

Be sure fuel valve (optional) is open. See Figure 12.

V. Starting Your Engine

An adult should start the engine.

Only allow children to start engine if

an adult has determined they are experienced and capable

of such operation.

If you are unable to start this engine

after following instructions in this

manual, contact your Authorized Tecumseh Servicing

Dealer. To avoid serious burn injuries or damage to your

engine, DO NOT attempt to start or troubleshoot this

engine in any other way. For example:

•

DO NOT use starting fluid.

•

DO NOT spray flammable vapors into carburetor or

onto air cleaner.

•

DO NOT put flammable liquids into carburetor or

onto air cleaner.

•

DO NOT operate engine or pull on starter rope with

spark plug removed. Fuel can spray from spark plug

hole and ignite.

This section contains starting instructions for several

different types of engines. In order to locate the instructions

that apply to your engine, first determine what type of

starter you have. If you have an electric starter See "A.

Engines with Electric Starters" instructions on next page. If

you have a manual recoil starter see "B. Engines with

Recoil Starters" instructions on page 9.
