String trimmer

String trimmers, also known as line trimmers, weed eaters, weed whackers, strimmers, and whipper snippers, are lawn and garden tools used for cutting grass and weeds. The typical string trimmer is a handheld motorized machine that uses a flexible monofilament line for cutting. The monofilament is mounted on a rotating spindle that spins at high speed.

There are two main types of string trimmers: gasoline-powered and electric. Gasoline-powered string trimmers are the most powerful type of string trimmer and can be used for large areas of land. Electric string trimmers are less powerful than gasoline-powered string trimmers but are more convenient to use because they do not produce fumes and do not require refueling.


You’ll need a spool of string that’s compatible with your trimmer. Most string trimmers take 0.065-inch diameter line, but some require a thicker 0.080-inch line. You can usually find this information in the trimmer’s operator manual or on a label on the trimmer itself. You’ll also need a pair of scissors to cut the string to length.


You will need a spool of string, a pair of gloves, and a Phillips head screwdriver. Begin by donning the gloves to protect your hands. Locate the spool of string. The spool is usually located underneath the trimmer head. Place the spool on a flat surface. Find the screws that hold the spool in place.


A screwdriver is a tool, manual or powered, for driving screws. The screwdriver is made up of two parts: the blade or tip, which engages with the screw, and the shank, which is held by the handle. The first documented screwdriver was invented by Robert Hooke in 1664.


If you have a string trimmer that needs new line, you’ll have to wind it yourself. It’s not a difficult process, but there are a few steps you need to follow. First, you’ll need to remove the old line from the spool. Next, you’ll need to thread the new line through the eyelet on the spool. Finally, you’ll need to wind the new line around the spool. Let’s get started.

Open the trimmer’s spool housing

1. Open the spool housing. This is usually accomplished by depressing a button or tabs on the side of the housing and swinging the housing open.
2. Cut a length of trimmer line using scissors, being sure to leave enough extra line to make winding easier. The amount of extra line you need will depend on the size of your trimmer’s spool, but a good rule of thumb is to leave at least 6 inches (15 cm) of extra line.
3. Feed the end of the trimmer line through the eyelet, hole, or bar located at one end of the spool. If your model has a bump feed head, you’ll need to feed the line through the head before feeding it through the spool.
4. Begin winding the line around the spool in a clockwise direction, being sure to keep the line tight as you wind. Continues winding until the spool is full or until you have used up all of your trimmer line.
5. Close the spool housing and press down on any tabs or buttons to lock it in place

Cut the string to the correct length

Cut the string to the correct length. Length will vary with different string trimmer models, so check your owner’s manual for the correct length. You’ll need about 2 feet of string for every 1 foot of swath you want to cut. Cut the string at an angle so that it can be easily inserted into the eyelet, or spool.

Insert the string into the spool

1. Unplug the trimmer.
2. Remove the spool cover from the trimmer head by depressing the spool locking lever and unscrewing the cover.
3. Pull out any old line from the spool.
4. Cut a length of new line that is about twice as long as the spool is wide. For example, if the spool is 2 inches wide, cut a 4-foot length of new line.
5. Insert one end of the new line into the eyelet on one side of the spool, then wrap it around the spool at least five times. Be sure to wrap the line in the direction indicated by an arrow on the spool, or clockwise if there is no arrow.
6.Thread the other end of the new line through the eyelet on the other side of the spool, then pull it tight against the first end of new line you installed. The two ends should be parallel and sticking out of opposite sides of the spool, about 1 inch apart.

Close the spool housing

If your string trimmer has a spool housing that can be opened, close it before you start winding the string. This will make it easier to wind the string evenly and prevent it from getting tangled.


If your string trimmer is not working properly, the first thing you should check is the string. If the string is broken or frayed, it will need to be replaced. To do this, first remove the spool of string from the trimmer. Next, cut off the damaged section of string and tie a knot at the end of the new string. Finally, wind the new string around the spool and replace it in the trimmer.

The string won’t feed

If the string on your trimmer won’t advance, there are several things you can do to troubleshoot the issue. Below are some tips to help you get your trimmer up and running again.

1. Check the spool for any damage or debris that could be preventing the string from feeding.
2. If the spool is damaged, replace it with a new one.
3. If there is debris on the spool, clean it off and try again.
4. Make sure the line is installed correctly according to the manufacturer’s instructions.
5. If the problem persists, take the trimmer to a qualified technician for further diagnosis and repairs.

The string is too short

If the string on your trimmer is too short, it won’t be able to reach the ground. To fix this, you’ll need to replace the string.

1. Start by removing the spool of string from the trimmer.
2. Cut a new piece of string that is about 18 inches long.
3. Wrap one end of the string around the spool and tie it in a knot.
4. Pull the string tight and wind it around the spool in a clockwise direction until there is about 6 inches of string left.
5. Tie the other end of the string to the spool and trim any excess string.
6. Reattach the spool to the trimmer and you’re ready to go!
