Releasing the spool: A spool is a cylindrical device where the string is wound. It helps you to tighten the string. Thus to help fix a new string, you need to release the spool to help take off the old string and wind a new set on it. 

Releasing the spool


To get to the spool you will need to remove the head of the trimmer by unscrewing the nuts and screws. This disconnects the head from the rest of the trimmer and enables you to access the spool.

Some of the models available today use different mechanisms of removing the spool. Therefore you should pay attention to your model and user manual for help if it is complicated.

Cut the string: Ensure that you get at least 25 feet of the string so that you will not need to keep replacing it after a short while. Also if your weed trimmer uses double strings, ensure that you get equal sizes of both strings. Thus cut string is called a swath and helps you to efficiently cut your fences and grass.

Before you even to replace the new string, ensure that the old one is out. Pull off the ends from the spindle. Also, ensure that the replacement strings are of the same size and strength as the old ones.

Start restringing: Inside the spool, there is a hole where you are supposed to enter the string and make sure it attaches. In cases of double strings, the holes are 2 to enable you to fix both strings. Push about a half-inch of the string carefully and slowly making sure that it attaches and is tight.

To ensure that you have the right size of a string, get a sample as you go to buy so that you acquire the same quality and size.

Start winding: Before you start to wind the string, check for an arrow that directs you on which side you are required to wind it. Then wind carefully ensuring that you form a fully first layer. Before you can overlap, form a second layer to ensure that during use, the string will not tangle.

Ensure that as you wind the string in, it is neat and in perfect rows. With 5 or 6 inches remaining, you can snap them into the retainer on the spool to ensure that it is held in place.

For double line trimmers, thread the strings through the eyelets on the outside of the trimmer head, depending on the model, then replace the spool into the trimmer head. This ensures that they are feeding smoothly. Then you can reattach the retaining cap.

Clip-in and replace: Once you are done winding from side to side, you can find the notch at the end of the spool and clip it in. Once that is done, replace the spool on to the trimmer. Then replace the trimmer head and replace the screws and nuts and ensure that it is tight. Thus prevents parts from coming off during use. Trimmers that have 2 strings also have 2 notches and you need to repeat the process for the 2nd string too.
