Reasons Why Stihl Hedge Trimmer Blades Won’T Move

1. Loose or damaged drive belt

The drive belt is what connects the engine to the blades and allows them to spin. If the belt is loose or damaged, it can slip and cause the blades to stop moving.

2. Clogged or dirty air filter

The air filter prevents dust and dirt from entering the engine. If the filter is clogged, it can restrict airflow and cause the engine to run poorly. This can lead to the blades not moving.

3. Carburetor problems

The carburetor mixes fuel and air to create a combustible mixture that is sent to the engine. If the carburetor is not adjusted properly, it can cause the engine to run poorly or not at all. This can also lead to the blades not moving.

4. Spark plug problems

The spark plug ignites the fuel-air mixture in the engine. If the spark plug is not working properly, it can cause the engine to misfire or not start at all. This can also lead to the blades not moving.

5. Worn or damaged blades

The blades are the cutting edge of the hedge trimmer. If the blades are worn or damaged, they can become dull and will not be able to cut through branches and shrubs effectively. This can lead to the blades becoming stuck and not moving.
