Stihl HL 91 K Problems and Solutions

some common issues and solutions for the Stihl HL 91 K hedge trimmer, as recommended by experts:

Issue: The trimmer is not starting. Solution:

  1. Check the fuel level. The trimmer should have at least 1/4 tank of fuel.
  2. Make sure the spark plug is properly gapped. The gap should be 0.028 inches.
  3. Clean the air filter. A dirty air filter can restrict airflow and prevent the engine from starting.
  4. Check the spark plug boot for cracks or damage.
  5. If the trimmer still won't start, contact a Stihl service center.

Issue: The trimmer is not cutting well. Solution:

  1. Make sure the blades are sharp. Dull blades will not cut well.
  2. Check the trimmer head for debris. Debris can build up in the trimmer head and prevent the blades from rotating freely.
  3. Adjust the trimmer head. The trimmer head may be adjusted too close to the ground, which can prevent the blades from cutting effectively.
  4. If the trimmer still is not cutting well, contact a Stihl service center.

Issue: The trimmer is smoking. Solution:

  1. Check the fuel level. The trimmer should not be run with an empty tank.
  2. Make sure the spark plug is properly gapped. A misfiring spark plug can cause the engine to smoke.
  3. Clean the air filter. A dirty air filter can restrict airflow and cause the engine to smoke.
  4. If the trimmer is still smoking, contact a Stihl service center.
