Weed Eater Repairing Guide
Weed eaters are one of the simplest yard tools to take care of. One of the first things you should do to keep your weed eater in good condition is to clean it. It is important not to clean your weed eater with water or gas, which may destroy the engine.
The next thing to maintain on your weed eater is string. When the string gets low you can remove the lower part of the head by pushing in slightly and turning the head counterclockwise. Cut the new string no shorter than 6 inches or the weed eater will not advance the string properly when in use. Thread the string back though the guides, making sure to follow the arrows on the guide.
If you find that the head of your weed eater is worn on bottom or hard to get off to replace the string then it is time to replace it. This can be done very simply by unscrewing the two screws at the top of the head and slipping it off. Then, just slide the new one on and tighten the screws.
If you find that your weed eater is losing power this may be caused by a dirty filter. To check, unscrew the knob or wing nut on the carburetor. Inside you will find the filter. If the filter is gray or black then it is time for it to be cleaned. The easiest way to clean it is to blow it out with an air compressor.
