If CRAFTSMAN 2-cycle engine oil (AIR-COOLED) is not available, use a good quality 2-cycle engine oil (AIRCOOLED) that has a recommended fuel mix of 40:1 IMPORTANT! Do not use: o AUTOMOTIVE OIL ° BOAT OILS (NMMA, BIA, etc,) 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 lubrication of 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 overheatand seize. Gasoline and oil must be premixed in a clean approved fuel container. Always use fresh regular unleaded gasoline. This engine is certified to operate on unleaded gasoline. IMPORTANT: Experience indicatesthat alcohol blended fuels called gasohol (or using ethanol or methanol) can attractmoisture,whichleads to oil/gasseparation 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 for 30 days or longer. Drain the gas tank, then run the fuel out of the carburetorand fuel lines by startingthe engine and letting itrun untilit stops Use fresh fuel next season See STORAGE instructionsfor additional information Never use engine or carburetorcleaner' 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 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. -12- These oils do not have proper additives for 2-cycle AIRCOOLED engines 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 gallon container,then securely replace the cap. • Shake the container. ° The mixture is now read,/for use. Fuel stabilizer can be added at this time if desired; follow mixing instructionson the label. FUEL MIXTURE CHART 40:1 Fuel:Oil Mix Ratio Gasoline 1 gallon 2 5 gallons 3.2 80 NOTE: Fuel containers may hold more than the specified amounL If too much gasoline is in the container, the resulting gas-to*oil fuel mixture will not be correct for proper engine operation OPERATION STOPPING YOUR ENGINE • Move the momentary switch to the OFF position. Do not release until the engine has completely stopped. • If the engine does not stop, move the choke lever to the full choke. _ THE SEMI-AUTOMATIC LINE HEAD WILL ARNING: TURN WHEN THE ENGINE STARTS° NOTE: If the engine dies with choke lever at "Off Choke" position,movethe choke lever to "Half Choke" Pull starter rope three times, Move choke lever to "Oft Choke" position, pull the rope until engine runs.

HOLD UNIT WITH YOUR HAND. MIXTURE SCREW (WITH MMITER CAP) IDLE SPEED SCREW Figure 28 THE SEMI-AUTOMATIC HEAD WILL BE SPINNING DURING MOST OF THIS PROCEDURE. WEAR YOUR PROTECTIVE EQUIPMENT AND OBSERVE ALL SAFETY PRECAUTIONS. IN MIXTURE ADJUSTMENT, RECHECK IDLE SPEED AFTER EACH ADJUSTMENT. THE SEMI-AUTOMATIC HEAD MUST NOT MOVE AT IDLE SPEED° If engine does not start, it may be flooded If in doubt read the section on flooded engine in the starting section of this manual prior to beginning any adjustments. The carburetor has been adjusted at the factory for sea level conditions. Ad ustments may become necessary if the unit is used at significantly higher altitudes or if you notice any of the following conditions: - Engine will not idle See "Idle Speed Adjustment" and "Mixture Speed Adjustment". o Engine dies or hesitates when it should accelerate See "Acceleration Check". • Loss of cutting power which is not corrected by air filter cleaning See "Mixture Speed Adjustment" ADJUSTING PROCEDURE IDLE SPEED ADJUSTMENT • Allow the warm engine to idle • Adjust the Idle Speed until the engine continues to run without stalling and without the semi-automatic head turning. - Turn screw clockwise to increase engine speed if engine stalls or dies - Turn screw counterclockwise to slow engine down. • Follow instructions in "Acceleration Check" • No further adjustments are necessary if performance is satisfactory. MIXTURE ADJUSTMENT • Support the lower end so the semi-automatic line head is off the ground and will not make contact with any object Be sure the trimmer line is extended to the maximum length allowed by the line limiter. • Start the engine. Allow engine to idle, then squeeze throttletrigger 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 screw beyond 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 ad usting screw) • Repeat step above unt I smooth acceleration is obtained Do not attempt to adjust the screw beyond the stop as damage will occur. NOTE: It may be necessary to repeat "Idle speed Adjustment" through "Acceleration Check;' to obtain correct adjustments, NOTE: There are two adjustments on the carburetor = The Idle Speed Adjustment. ° The Mixture Adjustment.. CARBURETOR PRESETS (Fig. 28) If your engine will not start due to suspected impropercarburetor adjustment, the following presets may be required If used, it is recommended that all steps withing the adjustment procedure be completed in order to assure a properly set carburetor. If presets are not needed, proceed to section "Idle Speed Adjustment". When making adjustments, be careful not to force the plastic limiter caps beyond the stops or damage will occur small adjustments can affect engine performance. It is important to make slight adjustments and test performance before proceeding, Each adjustment should be no more than 1/16th of a turn. • Turn the mixture adjustment fully counterclockwise to the limiter cap stops = Turn idle speed adjustment clockwise one full turn • If engine fails to start after performing carburetor presets, the unit may be flooded. Review the "Difficult Starting" section of the manual If problems continue, call the 1800 number listed on the front cover of this manual for further assistance. • Start the engine and operate for three (3) minutes to warm up Go to "Adjusting Procedure" Very -19- STORAGE Immediately prepare your unit for storage at the end of the season or if itwill not be used for 30 daysor more,.
