Preparing the Weed Eater

Before you can start your Stihl Weed Eater FS 91 R, you need to prepare it by following these steps:

1. Remove the spark plug boot. The spark plug boot is a rubber cap that covers the spark plug. To remove it, use a pair of pliers to grip the boot and twist it counterclockwise until it comes off.
2. Check the fuel level. The fuel tank is located on the back of the weed eater. To check the fuel level, remove the fuel cap and look inside the tank. The fuel level should be between the “full” and “empty” marks.
3. Prime the engine. Priming the engine helps to get the fuel flowing to the carburetor. To prime the engine, press the primer bulb several times until you see fuel coming out of the carburetor.

Starting your Stihl Weed Eater FS 91 R is a simple process that only takes a few minutes. By following these steps, you can get your weed eater up and running in no time.

Here are some additional tips for starting your weed eater:

• Make sure that the spark plug is properly installed and tightened.
• Use fresh fuel. Old fuel can cause the engine to start hard or not at all.
• Keep the air filter clean. A dirty air filter can restrict airflow to the carburetor and make it difficult to start the engine.
• If you are having trouble starting the engine, try turning the choke on and off a few times. This can help to clear any obstructions in the carburetor.

If you are still having trouble starting your weed eater, you can contact a Stihl dealer for assistance.

3. Stopping the Weed Eater

To stop the weed eater, follow these steps:

1. Let the engine run until it stops. This may take a few minutes.
2. Turn the fuel valve off. The fuel valve is located on the side of the engine. It is a small, round knob. Turn the knob clockwise to turn the fuel valve off.

4. Troubleshooting

If the weed eater is not starting or is running rough, there are a few things you can check:

• The spark plug: Make sure the spark plug is properly installed and that the gap is correct. The gap should be between 0.020 and 0.030 inches.
• The air filter: Clean or replace the air filter if it is dirty. A dirty air filter can restrict airflow to the engine, which can cause it to run rough or not start at all.
• The fuel filter: Check the fuel filter for blockages. A blocked fuel filter can prevent fuel from reaching the engine, which can also cause it to run rough or not start at all.
• The carburetor: If the engine is running rough, it may need to be adjusted or cleaned. A carburetor that is not adjusted properly can cause the engine to run too rich or too lean, which can both cause problems.
• The engine: If the engine is not starting or is running rough, it may need to be serviced. A mechanic can diagnose the problem and make the necessary repairs.

Starting and stopping a Stihl Weed Eater FS 91 R is a simple process. By following these steps, you can safely and easily operate your weed eater.
