5 Tips for Maintaining Your Cordless String Trimmer

A cordless string trimmer is a handy tool and, when combined with lawn mowers and other garden equipment, can make yard tasks a breeze.

But if you expect to wake up every weekend and fire up your trimmer with no issues, then you will need to maintain it, which can take some time and know-how.

A poorly maintained battery-powered trimmer can become susceptible to all sorts of hassles that most lawn owners want to avoid, and a weed eater that is not cared for will not do well hacking down tall grass or getting rid of unwanted weeds.

Below is expert advice on how to and how often you should maintain your cordless trimmer to achieve a beautiful lawn you can be proud of. 

How Often Should I Maintain My String Trimmer

It’s best to maintain your string trimmer on a regular basis to make sure your machine will have ample run time for lawn work and do the tasks of professional cutting tools. For an excellent job cutting, you will need to maintain your weed eater before use, after use, and most likely while using it on your green lawn. 

Here is a suggested maintenance schedule:

After every use: Clean debris from the trimmer head with gloves and a brush.

Before every use: Check and tighten screws with a screwdriver and check seals and switches. 

As needed: Replace the line spool as it wears down or sharpen the blades and the battery when it stops holding an adequate charge. 

Periodically: Check the air filter and bumper head and clean or replace them as needed.

Expert Care Tips

Taking care of a weed eater can be daunting at first, especially if it comes with a variety of attachments. A cordless battery grass trimmer offers its own special needs when compared to corded trimmers and gas trimmers, and lawn experts recommend taking extra care to keep these tools working well.

Here are some care tips for cordless lawn equipment to ensure effortless garden maintenance. 

Care	Process	Benefit
Check the Trimmer Line	Check periodically for fraying, splits, and breakage of the trimmer line; replace or rewind with a new trimmer line when needed	A strong trimmer line is able to cut a lawn as close as a razor does facial hairs, whereas a frayed or weak line with lead to jagged and ugly cuts that lead to common lawn diseases
Sharpen Blades	If your trimmer is equipped with blades, replace or sharpen the blades of the trimmer using a sharpening stone to maintain sharp, even edges.	Like a strong trimmer line, a sharp blade will cut through stalks of thick weeds and small trees as well as deal with the dense brush in no time
Inspect Battery Connection	Make sure battery connections are tight and secure and that nothing can enter the compartment once it’s sealed to prevent shorts and electrocution	Batteries power the trimmer, and any faulty connections will prevent the weed eater from working, so the battery connection must be maintained at all times to run these lawn care tools
Clean Trimmer	Regularly clean the trimmer of any dust, dirt, grime, and grass build-up with a damp cloth and a mild detergent if needed	Cleaning a trimmer allows you to see any cracks, chips, or structural issues before they become dangerous to you and the equipment you are using; clean equipment will operate better, leading to a healthier lawn
Check Trimmer Switch	Make sure the trimmer switch performs correctly and replace any damaged or faulty switches immediately	Controlling the speed and whether the machine is on or off is crucial to proper trimmer use, and the switch that controls it should be cleaned and replaced as needed

What Do I Need to Maintain a Weed Trimmer?

Taking care of essential lawn care equipment like weed eaters and leaf blowers is tricky but can become much easier with the right tools and materials.

Having access to the right stuff to open, clean, replace, and tighten all the dozens of attachments and components can help you keep your trimmer running and prevent deterioration over time. Here’s what you need:

Replacement Trimmer Line

As you whack, the line will wear down and need to be replaced. If you finish cutting material and weeds all over the lawn and your spool is near empty, it is an ideal time to switch out the spool, saving you time when you go to start on the next lawn care day. 

Sharpening Stone

The default cutting blade on your weed eater will wear down and may need to be replaced, but the life of the blade can be prolonged with the use of a sharpening stone. Keep your cutting edge sharp with a sharpening stone and slice down small trees and perennial shrubs with ease. 

Clippers 

Cordless models are versatile garden tools, and blades of grass and garden trees will wear down the cord quickly. Having needle-nose pliers with a clipper can make it easy for you to access and change the spool while snipping off the excess cord that could stall the machine on start-up. 

Damp Cloth

Before accessing critical parts of an electric weed eater, you should wipe down the outside with a damp cloth to make sure no dirt or debris is entering electrical parts. Common grass can easily be wiped off, and then the spool or battery can be replaced. 

Detergent

For thicker grime like mud or sap, you may need to add a detergent to the damp cloth and wipe the machine down vigorously. Once the foreign materials are removed, you can proceed with your planned maintenance tasks. 

Oil for Lubrication

Although engine oil is not needed, many moving parts and bearings require oil for lubrication. Weed eaters spin quickly, and the friction can become heat resulting in trimmers shutting down unless proper lubrication is used. Make sure to add the lubrication carefully to prevent stains and lawn damage. 

Brush for Cleaning 

If large chunks of debris are stuck inside the guard and whacking head, then you can use a brush to break it up and free the spool. Tough mud and rocks that get kicked up at a high speed can also become lodged tightly and need the tough bristles of a stiff brush to break them free. 

How to Get the Most Out of a Weed Whacker?

 In order to make your lawn care tasks easier, you should maintain your weed whacker and make sure that all the parts are in good condition and clean.

With a cordless string trimmer, you need to make sure that the electrical components are charged and sound and that the cord and bumper head are working well. Without these parts all being well maintained, it will be hard to get the most out of your cordless string trimmer.
