The auto feed system is really poorly designed and produced. But essentially its designed to feed when resistance is made against the centrifugal force when spinning. Basically two ways. You start trimming some heavy grass and that provides enough resistance to feed some line. Or you can fullly squeeze and quickly release the trigger a couple times. If you look inside the spool housing there will be a little lever that should move freely. Frequently inspect it as it goes out often. Also make sure theres no dirt build up on or around it or the rails it follows on the spool. If the tiny weight is missing then that lever is useless. On the bright side you can order them online for a couple bucks and they are pretty easy to replace.

You do not need to bump the head to advance the line. The machine has automatic line feed. If the line will not advance, then there is a problem with the line spool, possibly a tangle inside on it. Here is your instruction manual.

How do you remove the spool on an echo srm-2100 trimmer

Most units like yours has a tap head feed spool. To get to the line spool, you need to push the spool inward and rotate it to release it. The line spool is spring loaded, hence the need to push it in and rotate it to get it to release. You return the spool to the trimmer head housing after loading new line on it the same way, in reverse. Hope this info helps.

Tapping does not release string.

the string on the spool can become entangled and not release when required
if pressing the centre knob and pulling the string at the same time doesn
t get more string out the it will be in the spool
if the problem persists ,take it back for a warranty check as the button may not be releasing on tapping.

How do you advance the line on the trimmer

To advance the line on a trimmer just push down in the center of the spool head then pull on both lines at the same time and it should release and inch or so of line. If it has a spring on the inside of the head then just tap it in the center of the head on a hard corner surface while its running and it will release more line out. That is what ya call a bump feeder as such.

Hi and welcome to FixYa, I am Kelly (almost old at 56)
I looked up your parts and have come to the conclusion that you have items 13, 14 and 15 of this link:

Watch the video in this link:
it should help you.

I found the manual here:

SEE PAGE 7 of the above manual. Includes pictures. Try pressing in and rotating the spool to remove it.

1. Disconnect the unit from the power


2. Remove the spool by firmly pulling on the

tap button.

3. Clean entire surface of hub and spool.

4. Replace with a pre-wound spool or cut a

length of 30 feet of 0.065! (1.65 mm) diameter

Weed Eaterr brand line. Use of

heavier lines could overload and damage


WARNING: Never use wire, rope,

string, etc., which can break off and become a

dangerous missile.

5. Insert one end of the line about 1/2 inch (1

cm) into the small hole inside the spool.

6. Wind the line evenly and tightly onto the

spool. Wind in the direction of the arrow

found on the spool.

7. Push the line into the notch, leaving 3 to 5

inches (7 -- 12 cm) unwound.

8. Insert the line into the exit hole in the hub

as shown in the illustration.

9. Align the notch with the line exit hole.

10. Push the spool into the hub until it snaps
into place.

11. Pull on the line extending outside the hub

to release it from the notch; otherwise, the
unit will not function properly.

Thanks for choosing FixYa,

Having trouble replacing trimmer line

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.
Best regards, --W/D--

Feed the string

Both lines run in same direction on spool. Make sure it is not pinched or fed through any of the arms in the spool just coming out one on each side of the hole. Tap bottom on ground while trimmer is running to feed line. Each time you tap it line comes out approx 2 inch at a time Common mistake is when new line is added it gets put on in opposite directions. Both do they same direction-arrows on spool tell the way.

How do I load string in a P2500 string trimmer??

Remove spool by firmly pulling on tap button. Cut two pieces of line (0.080) about 12 feet. Insert the two ends of the line into the small holes inside the spool. Wind the lines evenly and tightly on the spool. Wind the string in the direction of the arrows on the spool. Push the lines into the notches on the spool leaving three or five inches hanging there. Insert the two ends in the two holes in the hub. Align the notches on the spool with the holes in the hub and push it in until it snaps into place. Pull on the lines to release them from the notches.

How do you refill the string on the homelite electric, straigh shaft, 13 in Trimmer?

Is the sting the cutting line at the bottom of the trimmer? If it is pull the spool out. At the bottom of the spool there is an arrow pointing in the direction that the line should be wound. When you first put in the line be sure to place the cutting line in the grove (V shape) and then when you put enough line around the spool. Thread the end of the line thru the hole on the side of the spool. Slide the spool over the shaft of the trimmer and it will click in. When the line is short just tap the spool lightly on the grass and it will feed out more line.
Good Luck.

Trimmer line on spool of Challenge 250 Watt Grass Trimmer.will not automatically feed as it is supposed to do when tapped on firm surface - can you let me see by diagram how the line is feed onto spool and...

I did a lot of searching for a manual but I guess Argos does not want their customers to know how to use their product. When you are use the trimmer, most rotate clockwise. You may find on the spool an arrow showing direction to wind line. Otherwise you will have to take it apart the trimmer and remember with direction the spool turns. Wind the string on the same direction turns. plus try a little wd40 on the line to keep it from sticking together.

My homelite trimmer string keeps getting stuck and when i tap it to release more string it doesn't the spring in it doesn't spring at all. I constantly have to stop take it apart pull enough string to edge...

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.
Best regards, --W/D--
