A weed eater is a handy garden tool that allows you to trim areas of your yard that are difficult to reach with a lawnmower, and it can cut even heavy weeds down in a matter of minutes. The line often hits posts, rocks, or concrete as you work, causing the spinning line to wear away faster. Fortunately, it is easy to maintain and restring a weed whacker.

Step 1 - Buy the Right Line

If your weed eater isn't doing its job, it may be time for restringing. However, it is important to buy the correct replacement line size, which ranges from 0.065 inches to 0.095 inches. If you purchase a size that is larger than the manufacturer recommends, it may cause the engine to wear out faster. Consult your owner's manual to figure out what you need before you buy.

If you purchase a replacement line, which comes in 300 to 900 foot lengths, thread the string through the guide by following the arrows on the spool. You may be able to buy replacement line on a pre-loaded spool, which makes this job much easier. The pre-loaded spools will cost a little more, but will save you time and effort.

Step 2 - Access the Spool

First, the spool cover must come off. Push the lock in and turn the spool in a counter-clockwise motion. Then, the cover should come right off. Check for a security device ring next. If there is one, remove it. The last thing to do is find the automatic feed button and take it off.

Step 3 - Clean up Debris

Through use, all kinds of things may end up caught in your weed eater. Take this time to clean out anything you see such as grass and weeds.

Step 4 - Release the Spool

After you've gotten your machine cleaned up, push the spool down to release the locking tabs. Then, just pull the spool out of the chamber.

Step 5 - Feed and Wrap the Line

Feed the line into the inferior deck. It is best if you feed the line in an inverted "J" motion to protect the end. Continue to wrap it in the direction of the arrows until it reaches the top of the chamber. Then, secure the line in the upper and lower deck groove.

Step 6 - Secure the Line

Put the spool back into its chamber. Thread the line into the left and right eye holes on the sides, and snap the spool securely into place. Grab both ends of the line and pull them at the same time. If there was a locking ring, put it back in. Be sure the guard is secure as well before using your weed eater. The guard protects you from flying debris or a mishap if the spool comes loose. One loose part can cause serious injury if the spool shoots off, so be sure everything is firmly in place before starting lawn work.

By following these easy steps, your weed eater will be working well again in no time. Proper replacement of the line and regular maintenance will ensure its continued use for many years to come.
