These small lawn care power equipment devices are known as the best weed eaters, string trimmers, or weed wackers (or whackers), and do wonderful trimming and edging. Any of these names are the same appliance for trimming and making the yard neat to include trimming close to sidewalks. They do not have blades to cut. They use a flexible monofilament line that looks like a thick fishing line, or ‘string’ to cut grass and weeds close to things. Using these devices eliminates the laborious effort and back pain pulling weeds out by hand. They are handy on slopes, hills, around tree trunks, and banks where a lawn mower would be dangerous or impossible to use. The monofilament comes in specific diameters for the machine it fits.

- Make sure the on/off switch is turned on.
- Be sure the spark plug is gapped correctly. If not, the engine will not start. You can remove the plug and clean the electrode part with a small toothbrush or wire brush. If it is fouling out from being wet with gasoline, replace it. Your manual will state the gap at xx-inches.
- With a dirty air cleaner replace or clean as stated in the instructions.
- Make sure the fuel filter is clean and if not, replace it.
- Smelling fuel after you try to start the engine usually means the engine is flooded with gasoline. Let it sit for 10 to 20-minutes for the gas to vaporize then try starting again.
- If your problems are not addressed in your User’s Manual, take the unit to an authorized service center where they know and understand your brand.
