how to start a stihl fs 111 rx weed eater

To start a Stihl FS 111 RX weed eater, follow these steps:

  1. Make sure you are wearing the proper safety gear, including eye protection, gloves, and long pants.
  2. Fill the fuel tank with a mixture of 2-cycle engine oil and gasoline. The ratio should be 50:1, which means 50 parts gasoline to 1 part 2-cycle engine oil.
  3. Prime the weed eater by pressing the primer bulb until it feels firm.
  4. Set the choke lever to the “Closed” position.
  5. Pull the recoil starter cord until the engine starts.
  6. Once the engine is started, set the choke lever to the “Open” position.
  7. Adjust the throttle trigger to the desired speed.

Here are some additional tips for starting a Stihl FS 111 RX weed eater:

  • If the weed eater does not start after a few pulls, press the primer bulb again and try again.
  • If the engine starts but then dies, try setting the choke lever to the “Open” position.
  • If the engine is still having trouble starting, you may need to clean or replace the spark plug.

Safety tips:

  • Always wear the proper safety gear when using a weed eater.
  • Be careful not to overfill the fuel tank.
  • Never start the weed eater indoors or in an area with poor ventilation.
  • Be aware of your surroundings and avoid spraying people or objects with the weed eater.
