BEFORE STARTING ENGINE:

WARNING:

BE SURE TO READ THE FUEL SAFETY INFORMATION IN THE SAFETY RULES SECTION ON PAGE 2 OF THIS MANUAL BEFOREYOU BEGIN.

IF YOU DO NOT UNDERSTAND THE FUEL SAFETY SECTION DO NOT ATTEMPT TO FUEL YOUR UNIT; SEEK HELP FROM SOMEONE WHO DOES UNDERSTAND

THE FUEL SAFETY SECTION OR CALL THE CUSTOMER ASSISTANCE HOTLINE

AT 1-800-235-5878.

GASOLINE The two-cycle engine on this product requires a fuel mix-

ture of regular unleaded gasoline and a high quality 40:1

2-cycle engine oil (AIR-COOLED)for lubrication of the bearings and other moving parts.The correct fuel/oil mix-

ture is 40:1 (see Fuel Mixture Chart). Too little oil or the

Incorrect oil type will cause poor performance and may

cause the engine to overheat and seize.

Gasoline and oil must be premixed in a clean approved fuel container. Always use fresh regular unleaded gaso-

line.

This engine is certified to operate on unleaded gasoline.

IMPORTANT: Experience indicates that alcohol blended fuels called gasohol (or using ethanol or methanol) can attract moisture, which leads to oil/gas separation and

formation of acids during storage. Acidic gas can dam-

age the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emp- tied before storage for 30 days or longer. Drain the gas tank, then run the fuel out of the carburetor and fue! lines by starting the engine and letting it run until it stops. Use fresh fuel next season. See STORAGE instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage

. may occur.

: : : IIII IIIIIII I IIIIIIIIIIII I IIII

40:1 2-CYCLE AIR-COOLED ENGINE OIL

CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is strongly recommended. This oil is specially blended with fuel stabilizers for increased fuel stability (extends fuel life up to 5 times longer) an'dreduced smoke.

If CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED)

is not available, use a good quality 2-cycle engine oil

(AIR-COOLED) that has a recommended fuel mix ratio of 40:1.

IMPORTANT! Do no use:

• AUTOMOTIVE OIL

- BOAT OILS (NMMA, BIA, etc.)

These oils do not have proper additives for 2-cycle engines (AIR,COOLED) and can cause engine damage.

GASOLINE AND OIL MIXTURE

Mix gasoline and oil as follows:

° Consult chart for correct quantities. ° Do not mix gasoline and oil directly in the unit's fuel

tank.

FOR ONE GALLON:

• Pour 3.2 ounces of high quality, 40:1 2-cycle engine oil (AIR-COOLED) into an empty, approved one gallon

gasoline container.

° Add one gallon of regular unleaded gasoline to the gal-

lon container, then securely replace the cap.

° Shake the container.

° The mixture is now ready for use. Fuel stabilizer can be

added at this time if desired; follow mixing instructions on the label.

FUEL STABILIZER

Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add

stabilizer to gasoline in fuel tank or storage container. Always follow the fuel tank or storage container. Always follow the fuel mix ratio found on the stabilizer container.

Run engine at least 5 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. You do not

have to drain the fuel tank for storage if you are using fuel stabilizer.

CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended with fuel stabilizers. If you do not use this Sears oil, you can add a fuel stabilizer (such as CRAFTSMAN No. 33500) to your fuel tank.

NOTE: Fuel containers may hold more than the specified amount. If too much gasoline is in the container, the resulting gas-to-oil fue! mixture will not be correct for proper engine operation.

OPERATING TIPS (Fig. 10)

i_ WARNING:

USE MINIMUM SPEED AND DO NOT CROWD THE LINE WHEN CUTTING AROUND HARD OBJECTS (ROCK, GRAVEL, FENCE POSTS, ETC.), WHICH

CAN DAMAGE THE SEMI-AUTOMATIC HEAD, BECOME ENTANGLED IN THE LINE, OR BE THROWN CAUSING A SERI-

OUS HAZARD.

ALWAYS WEAR EYE PROTECTION. NEVER LEAN OVER THE SEMI-AUTO- MATIC HEAD. ROCKS OR DEBRIS CAN

RICOCHET OR BE THROWN INTO EYES AND FACE AND CAUSE BLINDNESS OR OTHER SERIOUS INJURY:

• For tdmming or scalping, use partial throttle to increase

line life, especially:

- dudng light duty cutting.

- near objects around which the line can wrap or wear line such as small posts, trees, fence wire or con-

crete.

-. The line will easily remove grass and weeds from around walls, fences, trees and flower beds; but, it also can cut the tender bark of trees or shrubs and scar fences and

damage vinyl siding,above ground swimming pool metal skirting, etc.To help avoid damage especially to delicate vegetation or trees with tender bark, shorten line to 4-5 inches and use at partial throttle.

• The tip of the line does the cutting.You will achieve the best performance and minimum line wear by not crowding the line into cutting area.

• Always release throttle trigger and allow engine to return to idle speed when not cutting.

• Hold bottom of the semi-automatic head about 3 inch- es above ground and at an angle.

STORAGE

Immediately prepare your unit for storage at the end of

the season or if it will not be used for 30 days or more.

WARNING:

ALLOW THE ENGINE TO COOL, AND SECURE THE UNIT BEFORE STORING

OR TRANSPORTING IN A VEHICLE.

STORE UNIT AND FUEL IN AN AREA WHERE FUEL VAPORS CANNOT REACH SPARKS OR OPEN FLAMES FROM

WATER HEATERS, ELECTRIC MOTORS OR SWITCHES, FURNACES, ETC.

STORE UNIT WITH ALL GUARDS IN

PLACE. POSITION SO THAT ANY SHARP OBJECT CANNOT ACCIDENTALLY CAUSE INJURYTO PASSERS BY.

STORE THE UNIT OUT OF THE REACH OF CHILDREN.

,, ,,,,, ,, ,, .....

FUEL SYSTEM

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

components. Followthese instructions:

• Drain the fuel from He unit into an approved fuel con-

tainer.

• Drain the fuel lines and carburetor by starting the

engine and letting it run untilit stops.

• Allow the engine to cool before storage.

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, experience indicates that alcohol blended fuels, those that use ethanol or methanol (called gasohol or oxygenated fuel), can attract moisture and form acidic

gas which will damage your engine. To avoid engine problems, the fuel system should be emptied before stor- age of 30 days or longer.

GAS TRIMMER STORAGE INSTRUCTIONS

If your trimmer is to be stored for a period of time, clean it

• thoroughly prior to storage. Remove any dirt, leaves, oil,

grease, etc. Store in a clean dry area.

• Clean the entire unit.

• Clean air filter.Refer to "Customer Responsibilities."

•, Open the semi-automatic line head assembly and

clean any dirt, grass or debris that has collected.

• Inspect the cutting line. Old cutting line may be chall_y or sticky to the touch. Remove and discard old line and

_ install fresh new line.

° Lightly oil external metal surfaces to prevent rust from

forming.

° Re-assemble all loose parts, being sure that all han-

dles and guards are in place and are securely fas- tened. Replace any damaged parts.

° The recommended storage position is either vertically

with the fuel cap on top, or horizontally with the fuel cap up. Do not store unit with the cutting attach- ment up.

• Hang the unit by the brackets under the motor housing to avoid fuel leaks. Make sure the unit is positioned so that the line limiter cannot cause injury.

I _ CAUTION: WEAR PROTECTIVE GLOVES

WHEN HANDLING LINE LIMITER. THE BLADE IS SHARP AND CAN CUTYOU.

Fuel stabilizer is an acceptable alternative 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 instructions found on stabilizer containers. Run engine at least 5 minutes after adding stabilizer to allow the stabilizer to reach the car- buretor.

CRAFTSMAN 40:1 2-cycle engine oil (AIR*COOLED) is specially blended with fuel stabilizer. If you do not use this Sears oil, you can add a fuel stabilizer (such as CRAFTSMAN No. 33500) to your fuel tank.

INTERNAL ENGINE

• Remove spark plug and pour 1 teaspoon of 40:1 2- cycle engine oil (AIR-COOLED) through the spark plug

" opening. Slowly pull the starter rope 8 to 10 times to

distribute oil to inner engine surfaces.

• Replace spark plug with a new one of the recommended type and heat range. Refer to "Product Specifications."

• Clean air filth. Rear to =Customer Responsibilities."

• Re-install all covers and hardware removed for access; tighten all screws and fasteners.

• Check entire unit for loose screws, nuts, and bolts. Replace any damaged, broken, or worn parts.

• Lightly oil external metal surface to prevent rust from

forming.

• Use fresh fuel having the proper gasoline to oil ratio at

the beginning of the next season.

OTHER

• Do not store gasoline from one season to another.

• Replace your gasoline can if your can starts to rust.

Rust and/or dirt in your fuel system wi!t cause problems.

° Store your unit in a weltventilated area and covered, if

possible, to prevent dust and dirt accumulation. Do no

cover with plastic. Plastic cannot breathe and will

induce condensation and eventual rust or corrosion.

IMPORTANT: NEVER COVER UNiT WHILE ENGINE

AND EXHAUST AREAS ARE STILL WARM.
