How to rewind spool on trimmer head - Husqvarna Forest & Garden 125l 18" Gas Trimmer

1. Pull the spark plug wire from the top of the spark plug. Bend the wire to the side to prevent accidental starting.
2. Place trimmer on its side with the trimmer spool head facing you. Press the two tabs on the side of the spool head with your fingers.
   

1. Hold side of the head and slowly allow the head cover to push away from the inside of the spool head. There is a spring between the spool head housing and the spool that pushes out when releasing the cover.
   

1. Pll the knob and spool out of the spool head. The spring should come out on the back of the spool.
   

Electric Trimmer
1. 1 --> Unplug the Toro trimmer power cord from the electrical outlet.
   
2. 2 --> Lay the trimmer on its side. Hold the spool housing tight in one hand and twist the cap counterclockwise with your fingers. If necessary, use a pair of large slip joint pliers to start turning the cap. The cap is the center piece of the spool.
   
3. 3 --> Pull the cap off the spool and remove the spool from the housing.
   

The steps for replacing line in a single line trimmer head are virtually the same for many trimmer head types, like double line trimmer heads.
1. Remove the Trimmer Head Spool
Removing the spool is the first step in replacing trimmer line in any conventional trimmer head, but trimmer head spools can disassemble in different ways.
The trimmer head pictured above and below disassembles by simply unscrewing the knob around its arbor bolt. Other trimmer heads can use press tab and other twisting styles for disassembly.
2. Insert Trimmer Line and Wind the Line
Single line trimmer heads have just one channel in their spools for winding line. The channel will have a hole in it somewhere that keeps the line in place as it is wound around the spool. Insert one end of the trimmer line in the hole.
Depending on the trimmer head, it might be helpful to bend a small portion of the cutting line at an angle before inserting it in the starter hole. Also, cutting the line at an angle can help this first step on some trimmer heads.
Of course, it is also important to make sure that the replacement line matches the diameter specification of the trimmer head before beginning. Once the line is started correctly in the channel hole, you're ready to wind. Most trimmer heads will indicated the correct winding direction right on the spool somewhere.
It's also important to wind the line carefully, keeping it in neat rows as much as possible. The line will have a much higher chance to feed incorrectly during trimmer use if it suffers from sloppy winding.
3. Snap the Line into its Retaining Notch
A conventional trimmer head will have a retainer on its spool. Snap the end of the trimmer line into the retainer after it is wound around the spool. The retainer will hold the line in place as the spool is replaced in the trimmer head assembly.
4. Replace the Trimmer Head Spool
With the cutting line held in place, the spool is ready to be replaced in the trimmer head assembly.
First feed the extra trimmer line through the trimmer head eyelet. Make sure to release the line from the retainer before completely securing the spool into position.
Replace any knobs, bolts, or other trimmer head pieces removed during disassembly.
Your single line trimmer line is now reloaded, and your trimmer should be ready to get back to work.
Although there are many steps to reloading line the conventional way, a little practice and familiarity with your trimmer will speed the process up a great deal. Once you're up to speed, reloading trimmer line this way can take less than five minutes.

Hello. I just answered a similar question not twenty minutes ago. Hope this helps.

Please read all the way through this before beginning to actually rewind the spools.
1. Pull the spool off of the head. Clear the dust and debris out.
2. Note that it is actually two spools that are separated by a disc, and that the disc has a slot in it. The outer spool is the spool closest to the bump head, and the inner spool is the one that fits closest to the machine and has notches in it. If you turn the spool so that the inner spool base is up, you will see that there are decimal numbers next to the notches. The decimal numbers are your line size(s). I say sizes here as some machines will accept more than one line size. You will also notice arrows on the inner spool base, telling you which direction to wind the line on to the spool(s).
3. Wind the inner spool first: Put the end of the line into the hole that is in the core of the inner spool. insert ~1/8". Wind in the direction of the arrows until you get roughly even with the divider between the inner and outer spools. You want to end up with your line 180 degrees from the slot in the divider, and snap the line into the notch that is in the inner spool base. You want about 6" of line beyond the notch. Cut the line, leaving a 6" tail.
4. Wind the outer spool: Wind the outer spool like you did the inner spool, filling the spool as before, and ending at the slot in the divider. Feed the line through the slot and snap it into the notch. Cut a 6" tail as before.
5. Reinsert the spool: Get the spool close to the machine. Insert the tails into the grommets in the head, and snap the head into place.
6. Preparing the line for use: Push the spool in as if you were bumping it against the ground to advance the line. Grab the tails and pull. This will release the line from the notches, and should release about 1" of line in doing so.
You should be good to go.
Every so often, it's a good idea to put some graphite dust into the spool just before putting the spool back onto the machine. This helps when you are advancing the line. I do this every 8 to 10 times I rewind the spools.
If this fails to correct your problem with the spool, it would be best to purchase a replacement spool.

If this is your trimmer: http://www.searspartsdirect.com/partsdirect/getSubComp.pd?modelNumber=358791030&productCategoryId=1503820&brandId=0247&brandDescription=CRAFTSMAN&modelName=TRIMMER&diagramPageId=00001&componentDescription=DRIVESHAFT%20HANDLE%20SHIELD&documentId=P0710160&blt=06

The nut is a left handed thread and must be turned clockwise to remove the nut. Then you can remove the spool for rewinding or replacement.

Thanks for using FixYa.

on the spool there is a direction arrow showing you which wat to thread spool, each is in opposite position. If you do it the same way it will tangle

If you have the starter spool out (the one the rope goes in)...Here is what to do. Take the starter spool and change the rope out putting it back exactly as it was. Leave the rope hanging. Hold the spool and set it down on the rewind spring. Turn the spool on the rewind spring until you feel it is tight enough. While turning, hold the rope in the little slot in the spool so it can go around without hanging up. Once it is tight, get the rope in line with the spool opening and SLOWLY let the rope rewind. Put on the handle and put the unit back together.Good luck...Lee

not hard i suggest if its your first time doing this take it to your local lawnmower shop buy a new $8 spool from them they will be glad to showyou how to replace it then next time you can doo it yourself? the new spools already preload the string so you can see which way it loads ussually clockwise

It's sticking pretty good. Try what I do: Pull the head off and clean it out pretty good. Also clean where the spool attaches to the trimmer. Before you reassemble it, give it a shot of powdered graphite (I get mine at the hardware store. It's for locks). Reassemble the spool onto the trimmer. Bump it on the ground several times to distribute the graphite within the head. Now, press the head in and pull on the trimmer line. It should dispense a little line and stop, just like when the machine is in operation. If it works, you're done! If it doesn't work, you will need to replace the spool. They are available at the major hardware stores. Even if you have to replace the spool, the graphite trick is a good one. It'll keep the head dispensing line smoothly. I add the graphite probably every 7th or 8th time I rewind the spool.

It is fairly easy to restring trimmer. just follow the arrows on the spool.
Hope this helps

Okay, so the good news is that YOU are probably not stupid. If you have a Ryobi trimmer like I do, it might have taken you a while to figure out the "secret" on how to rewind the line. If you only had to learn the lesson once, you are smarter than I am. (I'm leaving myself a note for next time).

If you wind the line the wrong way, you go through line really fast until it clogs up inside the bump head and you are forced to try again. The trimmer has an arrow on the spool for the direction to re-wind the line. Think of it this way, TURN THE SPOOL IN THE DIRECTION OF THE ARROW! Don't do what I did and rewind the line in the direction of the arrow, that would be wrong.

Whether this is a "mistake", a way to sell more trimmers/parts/line, or simply bad tranlation from Japanese to Engrish, it really doesn't matter. You don't need to buy anything with the exception of new line.

Good Ruck,

Mark
