Source of power:

Several designs are available in the market; few of them can be powered up with the help of gasoline, many are equipped with a battery, and others can be plugged to the outdoor outlet as well. It is observed that the corded electrics are the cheapest option in the market, but they require a power outlet in the nearby location to work.

However, when the model has a minimal gap between these two; it is possible to get rid of all the weed with ease.

Safety matters:

Generally, string trimmers make debris fly around while cutting on the ground, and it can pose some safety issues to the people around.

Change the fuel filter from time to time:

  • In most of the string trimmer models, it is possible to remove fuel filters for easy cleaning.

It is better to check guidelines on manufacturer’s manual to get a clear idea about your specific model. In case if the debris is clogging the mesh screen of the filter, it must be replaced fast.

Clean the spark arrestor:

  • A spark arrestor can be found inside the muffler of the engine, and it plays an essential role in maintaining proper functioning of the system. Experts advise cleaning it at least one in 25 hours of use; however, replacement is recommended one in the season. In case, if your model is loaded with fiberglass spark arrestor; it must be replaced after every 25 hours of use because it doesn’t allow cleaning.

Cutting line replacement:

  • Due to continuous wear and tear, the string trimmer line becomes brittle and can break with ease. It is better to use non-rounded, high-quality string to ensure better cut while trimming your yard. It will also enhance the performance level of the string trimmer.

Degrease the strimmer:

  • By the end of the season, it is advised to decrease the trimmer to make it ready for the next year. You can use spray type degreaser for the dirty areas and wipe the area using a clean cloth after 10 to 15 minutes of application. After that, rinse off the unit and let it dry.
