Stihl BT 121 Problems and Solutions

some common issues and problems with the Stihl BT 121 chainsaw, along with solutions from experts:

Issue: The chainsaw won't start. Solution:

  1. Check the fuel level. The chainsaw won't start if the fuel tank is empty.
  2. Check the spark plug. If the spark plug is fouled or damaged, it won't create a spark, which is necessary to start the chainsaw.
  3. Check the air filter. If the air filter is clogged, it will restrict airflow to the engine, making it difficult to start.
  4. Check the throttle. Make sure the throttle is in the "start" position.
  5. If you've checked all of these things and the chainsaw still won't start, you may need to take it to a qualified technician.

Issue: The chainsaw is difficult to start. Solution:

  1. Follow the steps above for a chainsaw that won't start.
  2. If the chainsaw starts but is difficult to start, you may need to adjust the carburetor. This is a delicate procedure, so it's best to take the chainsaw to a qualified technician if you're not comfortable doing it yourself.

Issue: The chainsaw is losing power. Solution:

  1. Check the fuel level. If the fuel level is low, the chainsaw will lose power.
  2. Check the spark plug. If the spark plug is fouled or damaged, it won't create a spark, which will cause the chainsaw to lose power.
  3. Check the air filter. If the air filter is clogged, it will restrict airflow to the engine, making it lose power.
  4. If you've checked all of these things and the chainsaw is still losing power, you may need to take it to a qualified technician.

Issue: The chainsaw is overheating. Solution:

  1. Allow the chainsaw to cool down before operating it again.
  2. Make sure the chainsaw is getting enough air. If the chainsaw is operating in a confined space, it may not be getting enough air to cool down properly.
  3. Check the cooling fins. If the cooling fins are clogged with dirt or debris, they will not be able to dissipate heat properly, causing the chainsaw to overheat.
  4. If you've checked all of these things and the chainsaw is still overheating, you may need to take it to a qualified technician.
