Why Stihl Hedge Trimmer Keeps Cutting Out
1. Blocked Air Filter
The air filter is responsible for keeping dirt and debris out of the engine. If the air filter is clogged, it can restrict airflow to the engine, causing it to run lean and eventually stall. To clean the air filter, remove it from the trimmer and rinse it with warm water. Allow the air filter to dry completely before reinstalling it.
2. Dirty Spark Plug
The spark plug is responsible for igniting the fuel in the engine. If the spark plug is dirty, it can cause the engine to misfire and eventually stall. To clean the spark plug, remove it from the engine and use a spark plug cleaner to clean the electrodes. Reinstall the spark plug and try starting the engine.
3. Bad Fuel
Old or stale fuel can cause problems with the engine. If you suspect that the fuel is bad, drain the fuel tank and replace it with fresh fuel.
4. Clogged Fuel Filter
The fuel filter removes dirt and debris from the fuel before it reaches the engine. If the fuel filter is clogged, it can restrict the flow of fuel to the engine, causing it to run lean and eventually stall. To clean the fuel filter, remove it from the fuel line and rinse it with warm water. Allow the fuel filter to dry completely before reinstalling it.
5. Bad Carburetor
The carburetor is responsible for mixing the fuel and air in the correct proportions for the engine. If the carburetor is not adjusted properly, it can cause the engine to run lean or rich, which can lead to stalling. To adjust the carburetor, you will need to consult the owner’s manual for your trimmer.
6. Loose or Damaged Spark Plug Wire
The spark plug wire connects the spark plug to the ignition coil. If the spark plug wire is loose or damaged, it can cause the spark plug to misfire, which can lead to stalling. To check the spark plug wire, disconnect it from the spark plug and inspect it for damage. If the spark plug wire is damaged, replace it.
7. Faulty Ignition Coil
The ignition coil generates the spark that ignites the fuel in the engine. If the ignition coil is faulty, it can cause the engine to misfire and eventually stall. To test the ignition coil, you will need to use a multimeter. If the ignition coil is faulty, it will need to be replaced.
