I’ll also provide some tips on how to prevent this problem from happening in the future. So if you’re ready to get your hedge trimmer back up and running, let’s get started!

Reasons Why Can Start My Stihl Hedge Trimmer Won’T

No fuel

The most common reason why a Stihl hedge trimmer won’t start is because there is no fuel in the tank. Make sure the tank is full and that the fuel valve is open.
If the fuel valve is closed, it will prevent fuel from flowing to the engine. To open the fuel valve, turn the knob clockwise until it clicks.

Dirty fuel filter

A dirty fuel filter can restrict the flow of fuel to the engine, causing it to stall or not start at all. To clean the fuel filter, remove it from the trimmer and rinse it with warm, soapy water. Be sure to dry the filter thoroughly before reinstalling it.

Clogged air filter

A clogged air filter can prevent air from flowing to the engine, causing it to run lean and eventually stall. To clean the air filter, remove it from the trimmer and tap it gently against a hard surface to remove dirt and debris. You can also rinse the filter with warm, soapy water, but be sure to dry it thoroughly before reinstalling it.

Bad spark plug

A bad spark plug can prevent the engine from firing, causing it to not start. To check the spark plug, remove it from the engine and inspect it for damage. The electrodes should be clean and free of carbon deposits. If the spark plug is damaged, replace it with a new one.

Corroded spark plug wire

A corroded spark plug wire can prevent the spark plug from firing, causing the engine to not start. To check the spark plug wire, inspect it for damage. The wire should be free of cracks or breaks. If the spark plug wire is damaged, replace it with a new one.

Engine flooded

If the engine is flooded, it will not start because too much fuel is in the cylinder. To clear the flood, turn the fuel valve off and pull the starter cord several times to clear the excess fuel from the cylinder. Once the engine is clear, turn the fuel valve back on and try to start the engine again.

Engine seized

If the engine is seized, it will not start because the pistons are stuck. This can happen if the engine is run out of oil or if it is subjected to excessive heat. If the engine is seized, it will need to be repaired or replaced.

How to Troubleshoot: My STIHL Hedge Trimmer Won’t Start

Check the Power Source

First
ensure that the power source is functioning correctly. If you’re using a corded hedge trimmer
check the power cord for any damage or fraying. If you’re using a battery-powered trimmer
make sure the battery is fully charged and properly inserted.

Inspect the Fuel System

If you have a gas-powered hedge trimmer
check the fuel level and ensure that the fuel is fresh. Stale fuel can cause starting issues. Additionally
inspect the fuel lines and fuel filter for any blockages or damage.

Examine the Spark Plug

A faulty spark plug can prevent your hedge trimmer from starting. Remove the spark plug and inspect it for signs of wear or damage. If the spark plug is dirty or worn out
replace it with a new one.

Clean or Replace the Air Filter

A clogged air filter can restrict airflow to the engine
leading to starting problems. Remove the air filter and clean it thoroughly. If the air filter is damaged or excessively dirty
replace it with a new one.

Inspect the Ignition System

Check the ignition system components
including the ignition coil and wiring
for any signs of damage or wear. Faulty ignition components can prevent the engine from starting.

Check for Mechanical Issues

Inspect the cutting blades and gearbox for any obstructions or damage. Ensure that the blades move freely and that the gearbox is functioning properly. Additionally
check for any loose or damaged components that may affect the trimmer’s operation.

Consult a Professional

If you’ve gone through the troubleshooting steps and your STIHL hedge trimmer still won’t start
it may be time to seek professional assistance. A certified technician can diagnose and repair any underlying issues with your hedge trimmer.
