Stihl BT 121 Problems and Solutions
some common issues and problems with the Stihl BT 121, along with step-by-step solutions from experts:
Issue: The trimmer won't start. Solution:
- Check the fuel level. The tank should be at least half full.
- Make sure the spark plug is properly gapped. The gap should be between 0.028 and 0.032 inches.
- Check the air filter. It should be clean and free of debris.
- If the trimmer still won't start, try priming it. To do this, press the primer bulb several times until fuel flows into the carburetor.
Issue: The trimmer is smoking. Solution:
- Check the air filter. If it's clogged, it will restrict airflow and cause the trimmer to smoke.
- Check the spark plug. If it's fouled, it will cause the trimmer to run poorly and smoke.
- If the air filter and spark plug are clean, the problem may be with the carburetor. A carburetor adjustment may be necessary.
Issue: The trimmer line is not cutting. Solution:
- Make sure the trimmer line is properly installed. The line should be threaded through the eyelets on the trimmer head and secured with the retainer clip.
- Check the trimmer line for wear. If the line is frayed or damaged, it will not cut effectively.
- If the trimmer line is properly installed and not damaged, the problem may be with the trimmer head. The trimmer head may need to be cleaned or replaced.
Issue: The trimmer is vibrating excessively. Solution:
- Check the trimmer head. If the head is unbalanced, it will cause the trimmer to vibrate excessively.
- Check the trimmer line. If the line is too tight, it will cause the trimmer to vibrate excessively.
- If the trimmer head and trimmer line are not the problem, the problem may be with the engine. The engine may need to be balanced or repaired.
