Clean the string trimmer to keep it performing well. Dust, grime and caked-on grass clippings build up on the debris shield and trimmer head and can lead to inefficiency and possible malfunction if not cleaned. Wipe the trimmer parts down with a rag after use and before storing it. Do a deeper cleaning with a stiff brush and a damp cloth periodically. Use cotton swabs, lightly dampened with machine oil to clean exhausts and intakes and other hard-to-clean areas.
Use an air compressor or a can of compressed air to blow air into the trimmer engine vents and crevices to remove dirt and dust from inside.
Remember to inspect your string trimmer for any signs of wear or damage when you’re cleaning it.
Before cleaning or maintaining your string trimmer—particularly when handling the business end—always remove the spark plug from a gasoline-powered unit. Unplug the power cord or detach the battery from an electric unit.
Store your trimmer and accessories somewhere where they will be protected from dust and moisture, preferably in a garage or tool shed. This not only keeps them protected, it also keeps them organized so you can easily find the tool you need when you need it.
Remember to keep the instruction manual. Not only is it a great guide and resource on how to properly and safely use your string trimmer, the manual also has valuable information on how to care for it, find replacement parts and other important pieces of information.
