Troubleshooting

If the air filter is dirty or clogged, it can restrict airflow to the engine and prevent it from starting. To check the air filter, remove it from the engine and inspect it for dirt or debris. If the air filter is dirty, clean it or replace it with a new one.
2. Check the spark plug:
A faulty spark plug can also prevent the engine from starting. To check the spark plug, remove it from the engine and inspect it for damage. If the spark plug is damaged, replace it with a new one.3. Check the fuel line and carburetor:
A bad fuel line or carburetor can also cause problems with starting. To check the fuel line, make sure that it is clear of kinks or obstructions. To check the carburetor, remove it from the engine and clean it with carburetor cleaner.
4. Check the battery:
A weak battery can also cause problems with starting. To check the battery, use a voltmeter to test the voltage. If the battery voltage is below 12 volts, charge the battery or replace it with a new one.
5. Check the ignition system:
A problem with the ignition system can also prevent the engine from starting. To check the ignition system, use a spark tester to test the spark plugs. If the spark tester does not produce a spark, there is a problem with the ignition system.

Why won’t my Stihl hedge trimmer start?
There are a few possible reasons why your Stihl hedge trimmer won’t start. Here are some of the most common causes:
