IMPORTANT

Experience indicates that alcohol

blended fuels (called gasohol or using

ethanol or methanol) can attract mois-

ture which leads to separation and

formation of acids during storage.

Acidic gas can damage the fuel sys-

tem of an engine while in storage.

To avoid engine problems, empty the

fuel system before storage for 30 days

or longer. Drain the gas tank, start the

engine and let it run until the fue! lines

and carburetor are empty. Use fresh

fue! next season.

Never use engine or carburetor clean-

er products in the fuel tank or perma*

nent damage may occur.

standallwarningsandinstructions,let

yourAuthorizedServiceDealerper-

formtheseadjustments.

WARNING: Serious injury to the op-

erator and others can occur if the car-

buretor is not property adjusted. Keep

others away when making carburetor

adjustments. The blade shaft wil! be

spinning during most of this proc_'.__

Wear your protective equipment _:

observe all safety instructions.

Remove blade before making carbure-

tor adjustments. Do not make adjust-

ments from the blade side of the unit.

Hold the unit with your hand.

ment. The blade shaft must not turn at

idle speed to avoid serious injury to the

operator or others.

•Poor engine performance can be re-

suit of other causes such as dirty air

filter, carbon build-up on muffler out-

lets, etc. See "Troubleshooting

Chart" before proceeding with carbu-

retor adjustments.

•For best results, it is recommended

that you have your Sears Service

Center make all carburetor adjust-

ments. Your dealer has the training,

experience, and tools necessary to

properly adjust your unit to meet our

factory performance specifications.

This service is not covered by war-

ranty. If it becomes necessary for

you to make carburetor adjustments

yourself, follow the described proce-

dures very carefully.

• Very small adjustments can affect

engine performance, it is important

to turn the screw a very small

amount per adjustment and test per-

formance before making further ad-

justments. Each adjustment should

be no more than the width of the slot

in the adjusting screw.

•This is a complicated task. Follow

instructions in sequence as indi-

cated.

EDGER STORAGE

•Clean the entire unit.

•Clean air filter (see instructions).

CAUTION: Wear protective gloves

when handling the blade. The blade is

sharp and can cut you even when it is

not moving.

•Inspect the guard area and clean

any dirt, grass, leaves, or debris that

has collected. Inspect the blade and

blade guard; replace a blade that is

bent, warped, cracked, broken, or

damaged in any other way.

• Lightly oil external metal surfaces.

•Apply a coating of oil to the entire

surface of the blade; wrap it in heavy

paper or cloth.

•Be sure all handles and guards are

in place and are securely fastened.

Replace any damaged parts.

•Check entire unit for loose screws,

nuts, and bolts. Replace any dam-

aged, worn, or broken parts.

•Do not cover with plastic. Plastic

cannot breathe and will induce con-

densation and eventual rust or corro-

sion.

FUEL SYSTEM

Never use engine or carburetor clean-

er products in the fue! tank or perma-

nent damage may occur to fuel system

components. Follow these instructions.

• Drain the fuel from the unit into an

approved fuel container.

• Drain the fuel lines and carburetor by

starting the engine and letting it run

until it stops.

•Allow engine to cool before storage.

IMPORTANT: It is important to prevent

gum deposits from forming in essential

fuel system parts such as the carbure-

tor, fuel filter, fuel hose, or tank during

storage. Also, experience indicates

that alcohol blended fuels, those that

use ethanol or methanol (called

gasohol or oxygenated fuel), can at-

tract moisture and form acidic gas

which will damage your engine. To

avoid engine problems, the fuel sys-

tem should be emptied before storage

for 30 days or longer.

Fuel stabilizer is an acceptable alter-

native in minimizing the formation of

fuel gum deposits during storage. Add

stabilizer to the gasoline in the fuel

tank or fuel storage container. Always

follow the mix instructionsfound on

stabilizer containers. Run engine at

least 5 minutes after adding stabilizer

to allow the stabilizer to reach the cap

buretor.

CRAFTSMAN 40:1 2-cycle engine oil

(AIR COOLED) is blended with fuel sta-

bilizer, if you do not use this Sears oil,

you can add a fuel stabilizer (such as

Craftsman No. 33500) to you fuel tank.

INTERNAL ENGINE

•Remove spark plug and pour I tea-

spoon of 40:1 2-cycle engine oil (AIR

COOLED)through the spark plug

opening. Slowly pull the starter rope

8 to t0 times to distribute oil to inner

engine surfaces.

• Replace spark plug with anew one of

recommended type and heat range.

•Clean air filter. Refer to Customer

Responsibilities.

• Re-insta!l all covers and hardware

removed for access; tighten all

screws and fasteners.

•Check entire unit for loose screws,

nuts, and bolts. Replace any dam-

aged, broken, or worn parts.

•User fresh fuel next season.

OTHER

•Do not store gasoline from one sea-

son to another.

°Replace your gasoline can if your

can starts to rust. Rust and/or dirt in

your fuel system wilt cause prob-

lems.

°Store your unit in a well ventilated

area and covered, if possible, to pre-

vent dust and dirt accumulation. Do

not cover with plastic. Plastic cannot

breathe and wilt induce condensa-

tion and eventual rust or corrosion.

IMPORTANT: Never cover unit while

engine and exhaust areas are still

warm.
