So, here are some techniques you can follow to troubleshoot your Husqvarna hedge trimmer problems by targeting the potential reasons.

Damaged Spark Plug

Is your hedge trimmer not starting? If so, you should check the spark plug of it first. A defective spark plug usually causes a hedge trimmer’s starting problem.

Now, how will you know if the spark plug is worn out or not? Take a spark plug tester and inspect for the damage signs. A damaged spark plug won’t give a spark between the tester terminals.

Replacing the defective spark plug will fix the Husqvarna hedge trimmer not starting problem. But if the spark plug is okay, you will need to check whether the carburetor is okay or not.

Clogged Carburetor

A clogged carburetor is an actual troublemaker! Your hedge trimmer may not start because of a clogged carburetor. Another major issue that can arise from it is your Husqvarna hedge trimmer won’t stay running.

Your hedge trimmer may also run rough by the carburetor issue. In this case, get your carburetor repaired or replaced as soon as possible to run your trimmer without annoyance.

 You can also prevent this from happening by doing proper maintenance of your hedge trimmer. Cleaning the carburetor will avert the carburetor from clogging up with old fuel.

If you don’t do so, the long-time leftover fuel will become thick and block the carburetor. So, try to clean it using carburetor cleaner. Otherwise, replacing the carburetor would fix the problem too.

But what if the carburetor is clean, but still the trimmer starts and stalls? If this happens, check the screen arrestor of your hedge trimmer. 

Clogged Screen Arrestor

A congested screen arrestor is another potential reason behind a hedge trimmer malfunctioning. The arrestor screen can get blocked by debris and dirt if you haven’t cleaned it for a long time.

However, troubleshooting this issue is both easy and complex. An easy fix would be cleaning out the arrestor screen with a brush. 

If cleansing the screen arrestor does not work, you better replace the arrestor. Replacing it is not easy, so take your Husqvarna hedge trimmer to a professional to fix it.

Fuel Filter Issue

If the fuel filter is blocked, your hedge trimmer will not start or run rough. This happens when there is any old fuel left in the fuel tank for a long time. To get rid of this trouble, drain the old fuel from the tank and replace the fuel filter with a fresh one.

Damaged or Broken Clutch

The blades won’t turn or move when the clutch is damaged. Sometimes it may require a simple tensioning if the problem is minor. Otherwise, you will need to visit a technician and replace the damaged clutch.

Trimming Heavy Bushes

Shoving heavy bushes causes a shortage of airflow in the hedge trimmer motor. As a result, the engine gets overheated. To troubleshoot this issue, shut off your hedge trimmer and let it cool down the machine for a while.

Clogged Cutters

Clogged cutters with heavy grasses or debris mainly cause your trimmer not to cut shrubs and hedges even if it’s running. This is a rare case, but it’s frustrating as hell.

So, if this ever happens to your Husqvarna hedge trimmer, clean out the debris and Twiggs stuck in the cutters. Then grease the cutter using little oil and clean the blades as well.
