How to Repair a Weed Eater

Weed eaters are available in many different brands and models to meet their ever-rising demand. As technology advances, a majority of weed trimmer manufacturers have come up with more creative versions that are powered by electricity, batteries, or gas.

Weed trimmers are easy to operate, especially when they’re in the correct working order. However, if these simple tools develop some defects, it becomes very difficult for you to start them, thus causing a lot of disappointments in the long run.

Unlike lawn mowers, weed trimmers are easy to maintain, and problems are easy to identify. The most common causes of poor performance include clogged air filters, overstayed fuel, dirty spark plugs, or problems with the carburetor.

Tools You’ll Need

Before you start the repair procedure, you’ll need these special tools to make the process a success.

  • A screwdriver
  • Socket wrench
  • Charging tester
  • A new spark plug (if needed)
  • New connectors (if needed)
  • New wires (if needed)

First Things First

Repairing a weed eater may be challenging, especially when you don’t have an idea of where to start. There are several reasons that may cause a trimmer to stop working, so recognizing each of these factors is the first step toward achieving a faster repair.

Double check the user manual

Since most trimmers come in different versions, it’s recommended that you first double check the user manual to ensure that you follow the correct procedure when starting the engine.

Check the spark plug and the air filter

If you try starting the engine several times and the problem persists, consider checking the air filters and the spark plugs for any signs of dirt clogging. Use a screwdriver to open up the parts, then use hot water to rinse these areas. If the air filter or the spark plug is damaged, consider replacing it with a new one.

Change the fuel and the fuel filters

If you check the air filter and the spark plug and still the problem persists, consider changing the fuel and the fuel filter. To replace the fuel, simply turn the string trimmer upside down or use a siphon tube to empty your trimmer’s fuel tank. Check and replace the fuel filter, then refuel your weed eater with fresh fuel recommended by the manufacturer.

How to Repair Your Weed Eater

Now that we’ve reviewed some of the common causes of a faulty weed eater, this guide will give you a step-by-step procedure on how to repair it.

The spark plug

Earlier on in this post, we pointed out that checking the spark plug was one of the first steps to consider when diagnosing a problem.

With the help of your screwdriver and a socket wrench, remove the spark plug completely to check for any damages. Double check the spark plug for any damages. If there are any, replace it with a new spark plug, then connect it back into place.

The ignition module

If the problem persists, check the ignition module through disconnecting the “ON”/”OFF” switches. Check for any loose connections, then try pulling the starter rope to check for sparks. If you notice any loose wires, try fixing them or replacing them, then reassemble the entire system.

Check the charge

After you’ve double checked all the above areas, it’s time to test if your trimmer is fully functional. Using a power or a charging tester, check the starter and the coils for proper charge. If the current flows out perfectly, that mean that your weed trimmer is in good working condition and is ready to start operating.

Bottom line

Apart from the obvious problem of the weed eater’s failing to start, there are other common problems that weed eaters face in their line of duty. Among them include failing to cut grass, rough idling, and lacking enough power.

Some of these problems, such as the trimmer failing to cut grass, are easy to solve, but the rough idling means the engine has a problem that must be solved by an authorized dealer.

Having said that, I believe that you’ll now be able to troubleshoot any problem you discover with your weed trimmer regardless of how challenging it may sound. Through reading this guide, you’ll be able to save time and money that you would otherwise have spent taking a trip your nearest dealer.
