OPERATION

BEFORE STARTING ENGINE:

WARNING:

BE SURE TO READ THE FUEL SAFETY INFORMATION IN THE SAFETY RULES

SECTION ON PAGE 2 OF THIS MANUAL BEFORE YOU BEGIN.

IF YOU DO NOT UNDERSTAND THE FUEL SAFETY SECTION DO NOT AI"rEMPT TO FUEL YOUR UNIT; SEEK HELP FROM

SOMEONE THAT DOES UNDERSTAND THE FUEL SAFETY SECTION OR CALL

THE CUSTOMER ASSISTANCE HOTUNE AT 1-800-235-5878.

GASOLINE

The two-cycle engine on this product requires a fuel mixture of regular unleaded gasoline and a high quality 40:1 2-cycle engine oil (AIR-COOLED) for lubricationof the bearings and other moving parts. The correct fuel/oil

mixture 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 unleadedgasoline.

IMPORTANT: Experience indicates that alcoholblended fuels called gasohol (or using ethanol or methanol) can

attractmoisture, which leads to oil/gasseparation and for- mation 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 for 30 days or longer. Drain the gas tank,

then run the fuel out of the carburetor and fuel lines by

startingthe engineand lettingitrun untilitstops.Use fresh

fuel next season. See STORAGE instructionsfor addi- tional information.Never use engine orcarburetorcleaner

products in the fuel tank or permanent damage may

Occur.

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 mix ratio found on the stabilizer container. Run engine at least 5 minutes after adding sta-

bilizer to allowthe stabilizer to reach the carburetor. You do not have to drain the fuel tank for storage if you are

using fuel stabilizer.

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) and reduced smoke.

If CRAFTSMAN 2-cycle engine oil (AIR-COOLED) is not available, use a good quality 2-cyoie engine oil (AIR- COOLED) that has a recommended fuel mix of 40:1.

IMPORTANT! Do not use:

• AUTOMOTIVE OIL

• BOAT OILS (NMMA, BIA, etc.)

These oils do not have proper additives for 2-cyole 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, 2-cycle engine oil

(AIR-COOLED) into any empty, approved one gallon

gasoline container.

• Add one gallon of regular unleaded gasoline to the

galloncontainer, 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 instruc- tionson the label.

FUEL MIXTURE CHART

40:1 Fuel:Oil Mix Ratio

1 gallon 3.2

2.5 gallons 8.0

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

proper engine operation.

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 yourfuel tank.

fifth pull. If so, go to the next step immediately.

• Move the choke lever to the "Half Choke"position.

• Pull the starter rope sharply until the engine runs, but

no more than six pulls.

Once the engine starts, allow the engine to run 10 sec- onds, then move the choke lever to"OffChoke; Allow the

engine to run for 30 more seconds at "OffChoke"before releasing the throttletrigger.

DIFFICULT STARTING OR FLOODED ENGINE

The engine may be floodedwith too much fuel if it has not started after 20 pulis.

Flooded engines can be cleared of excess fuel with the

following procedure:

• Move the choke leverto the =OffChoke" position.

• Squeeze and holdthe throttletrigger.

• Pull starter ropehandle untilengine starts. Starting could require pulling starter rope handle many

times depending on how badly unitis flooded.

If engine still fails to start, refer to "TROUBLE SHOOT-

ING" chart or call the 1-800 number listed on the front cover of this manual.

OPERATION

UNE TRIMMER TIPS (Fig. 10) TECHNIOUES (Flg.11, 12, 13 &14)

• TRIMMING - Allow only the tip of the line to make contact. Do not force trimmer line into work area.

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

OR BE THROWN CAUSING A SERI-

OUS HAZARD.

ALWAYS WEAR EYE PROTECTION. NEV- ER LEAN OVER THE SEMI-AUTOMATIC

HEAD. ROCKS OR DEBRIS CAN RICO- CHET OR BE THROWN INTO EYES AND FACE AND CAUSE BLINDNESS OR

OTHER SERIOUS INJURY.

• For trimming or scalping, use partial throttle to increase line life, especially:

- duringlight duty cutting.

- near objectsaround which the line can wrap or wear

linesuch as small posts,trees, fence wire or concrete.

• The linewill easily remove grassand 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 groundswimmingpool metal skirting,etc.To helpavoid damage especially to delicate

vegetation or trees with tender bark, shorten lice to 4-5 inchesand use at partialthrottle.

• 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 tdgger and allow engine to return to idle speed when not cutting.

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

TRIMMING

REMEMBER

Keep semi-auto- matic head 3

inches above the groundwhile

trimming.

Figure 11

• SCALPING - The scalping technique removes

unwanted vegetation. Allow the tip of the lineto strike the ground around trees, posts, monuments,etc. This

technique increases line wear.

* Start the engine. Allow engine to idle, then squeeze

throttle trigger fully.

NOTE: Perform steps below at full throttle.

• Turn mixture screw counterclockwiseto the limiter cap stop.

• Run engine at full throttle for 30 seconds.

• If engine is running rough, turn mixture screw clockwise

in 1/16th turn increments until engine just starts to run

smoothly.

• Do not attempt to adjust screwbeyond stops as damage will occur.

• After completing adjustments, check for acceleration.

• If the unit accelerates and runs smoothly, no further adjustments are necessary. If not, proceed to

"Acceleration Check".

ACCELERATION CHECK

• Allow engine to idle.

• Squeeze trigger fully.

- If performance is satisfactory (engine accelerates smoothly), no further adjustments are necessary.

- If the engine does not accelerate smoothly, turn the

mixture screw counterclockwise a small amount (no more than the width of the slot in the adjustingscrew).

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 SE- CURE 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 INJURY TO PASSER BY.

STORE THE UNIT OUT OF THE REACH

OF CHILDREN.

GAS TRIMMER STORAGE INSTRUCTIONS

If your tdmmer is to be stored for a pedod of time, clean

it thoroughly pdor to storage. Remove any dirt, leaves, oil, grease, etc. Store in a clean dry area.

• Clean the entire unit.

• Clean air filter. Refer to =CustomerResponsibilities".

• Open the semi-automatic head assembly and clean any dirt, grass or debristhat has collected.

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

and installfresh new line.

• Lightlyoil 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, above the engine.

• The unit can be hung by the drive shaft housing so that the line limiter cannot cause injury.

J_l) CAUTION: Wear protective gloves when

handling Line Umiter. The blade is sharp and can cut you.

FUEL SYSTEM

Never use engine or carburetor cleaner products in the

fuel tank or permanent damage mayoccur to fuel system components.

Followthese instructions:

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

tainer.

• Drain the fuel lines and carburetor by starting the

engine and lettingit run until it stops.

• Allowthe 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, these that use ethanol or methanol (called gasohcl 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.

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 container. 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 stabilizers. If you do not use this Sears oil, you can add a fuel stabitizer (such as

CRAFTSMAN No. 33500) to your fuel tank.

INTERNAL ENGINE

• Remove spark plug and pour t teaspoon of 40:1 oil throughthe spark plug opening. Slowly pullthe starter

rope 8 to 10 times to distribute oil to inner engine sur- faces.

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

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

• Lightlyoil external metal surfaces to prevent rustfrom forming.

• Usefresh fuel havingthe proper gasoline to oil ratioat 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 will cause prob-

lems.

• Store your unit ina well ventilated area and covered, if

possible,to prevent dust and dirt accumulation. Do not cover with plastic. Plastic cannot breathe and will

induce condensationand eventual rust or corrosion.

IMPORTANT: Never cover unit while engine and exhaust

areas are stillwarm,
