CARBURETOR ADJUSTMENT

_,WARNING:

Keep others away

when making idle speed adjustments. The trimmer head will be spinning dur- ing most of this procedure. Wear your protective equipment and observe all safety precautions. After making ad- justments, the trimmer head must not move or spin at idle speed.

The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the fol- lowing conditions:

•Engine will not idle when the throttle is released.

•The trimmer head moves or spins at idle.

Make adjustments with the unit sup- ported so the cutting attachment is off the ground and will not make contact with any object. Hold the unit by hand while running and making adjustments. Keep all parts of your body away from the cutting attachment and muffler.

Idle Speed Adjustment

Allow engine to idle. Adjust speed until engine runs without trimmer head moving or spinning (idle too fast) or engine stalling (idle speed too slow).

A'IWARNING: Perform the follow- ing steps after each use:

•Allow engine to cool before storing or transporting.

•Store unit and fuel in a well venti-

lated 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 unit so that any sharp ob- ject cannot accidentally cause injury.

•Store unit and fuel well out of the reach of children.

SEASONAL STORAGE

Prepare unit for storage at end of sea- son or if it will not be used for 30 days or more.

If your unit is to be stored for a period of time:

•Clean the entire unit before lengthy storage.

•Store in a clean dry area.

•Lightly oil external metal surfaces.

•Turn idle speed screw clockwise to

increase engine speed if engine stalls or dies.

•Turn idle speed screw counterclock- wise to decrease engine speed if trimmer head moves or spins at idle.

If you require further assistance or are unsure about performing this proce-

dure, contact your Sears Service Cen- ter or call our customer assistance

FUEL SYSTEM

Empty the fuel system before storage for 30 days or longer. Drain the gas

tank, start the engine and let it run un- til the fuel lines and carburetor are

empty. Use fresh fuel next season. Under FUELING ENGINE in the OPERA-

TION section of this manual, see mes- sage labeled IMPORTANT regarding the use of gasohol in your engine.

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. Follow the mix instructions found on stabilizer

container. Run engine at least 3 min- utes after adding stabilizer.

Craftsman 40:1,2-cycle engine oil (air cooled) is already blended with fuel stabilizer. If you do not use this Sears oil, you can add a fuel stabilizer to your fuel tank.
