should not require adjustment. If your engine does

not operate properly due to suspected carburetor
problems, take your Yard Vacuum to a Sears Service
Center for repair and adjustment.

YardVacuum

Clean the equipment thoroughly.
Wipe equipment with an oiled rag to prevent rust.
Use a light oil or silicone to wipe.
Service the engine following instructions below.
Store unit in a clean, dry area. Do not store next to

corrosive materials such as fertilizer.

Engine

IMPORTANT: It is important to prevent gum deposits

from forming in essential fuel system parts such as
the carburetor, fuel filter, fuel hose, or tank during
storage. Also, alcohol blended fuels (called gasohol or

using ethanol or methanol) can attract moisture which
leads to separation and formation of acids during

storage. Acidic gas can damage the fuel system of an
engine while in storage.

To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow

these instruction:

Drain the fuel tank.
Start the engine and let it run until the fuel lines

and carburetor are empty.
Drain carburetor.

Never use engine or carburetor cleaner products
in the fuel tank or permanent damage may occur.

NOTE: Fuel stabilizer is an acceptable altemative in

minimizing the formation of fuel gum deposits during
storage.

Add stabilizer to gasoline in fuel tank or storage
container.

• Always follow the mix ratio found on stabilizer
container.

• Run engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach the

carburetor.

• Do not drain the gas tank and carburetor if using
fuel stabilizer. Drain all the oil from the

crankcase (this should be done after the engine
has been operated and is still warm) and refill the

crankcase with fresh oil.

If you have d rained the fuel tank, protect the inside of
the engine as follows:

Remove spark plug, pour approximately 1/2
ounce (approximately one tablespoon) of engine
oil into cylinder and crank slowly to distribute oil.

Replace spark plug.

Other

Do not store gasoline from one season to

another.

Replace the gasoline can if it starts to rust. Rust

and/or dirt in the gasoline will cause problems.

Store unit in a clean, dry area. Do not store next
to corrosive materials, such as fertilizer.

NOTE: If storing in an unventilated or metal storage
shed, be certain to rustproof the equipment by coat-

ing with a light oil or silicone.
