4 Steps to Starting Your Weed Trimmer Again

Trimming your lawn can be a simple, straightforward task when you have the proper equipment that is in working order. When Weed Eater is your brand of choice, you can choose from gas or electric string trimmers to cut closely around poles and other objects. Unfortunately, even a string trimmer of a well-known brand may sometimes malfunction and refuse to start. Instead of getting frustrated when that happens, check the trimmer for several common problems that can keep it from functioning, as it should.

Fuel Issues

A gasoline-powered weed trimmer that won't start may have a fuel-related problem. First and foremost, check whether or not enough fuel to power the trimmer is in its fuel tank. If the fuel level is low, the trimmer may not start. Fill the tank, and try to start the trimmer. If the fuel is left over from last year, however, it should be replaced with fresh gasoline. Ensure that you have the proper mixture of 2-cycle oil and gasoline for your Weed Eater trimmer. The Weed Eater Company recommends using unleaded gasoline mixed with 2-cycle oil at a ratio of 40 parts unleaded gasoline to 1 part 2-cycle oil.

Spark Plug Problems

If the Weed Eater trimmer refuses to respond in any way when you try to start it, then it may have a dirty or faulty spark plug. Cleaning the spark plug with a wire brush to remove corrosion or dirt may allow a connection that restores the trimmer to working order. If cleaning the spark plug doesn't do the trick, then simply pull off the spark plug cover, remove the old spark plug. Install a new spark plug, replace the spark plug cover and try starting the trimmer again.

Other Malfunctions

Sometimes too many attempts to start a trimmer can result in a flooded engine. In that case, position the trimmer's choke lever to "Run," and pull the cord to remove excess fuel. That procedure may require several repetitions until the engine starts. A clogged air filter also can cause a trimmer to remain dormant. Check the air filter for dirt and debris. If necessary, clean and replace the air filter before trying to start the machine again. A dirty or clogged fuel filter may keep fuel from reaching the carburetor. Remove the old fuel filter, and replace it with a new one before trying to start the trimmer again.

Electrical Issues

When an electric Weed Eater trimmer won't start, sometimes the most probable cause actually is the cause. Check an electric trimmer to ensure its extension cord is plugged firmly into the machine and plugged firmly into an electrical outlet. A faulty extension cord also may be the problem. Swapping the faulty extension cord for another extension cord that is in working order can perform a quick fix. Also, ensure the trimmer's switch is in the "On" position. Performing a quick check of the fuse or circuit breaker that governs the electrical outlet into which the Weed Eater is plugged is practical to ensure no problem exists with the electric power.
