string braking on my trimmer

I have the EGO string trimmer. After I ran out of string I bought the best .095 string at Home Depot and It won't last through more that a couple of feet. We know how to use this machine and don't over rev or drop it too close to the ground. I bought another high quality brand and same thing. It brakes off at the hole so I have to remove the cap to fix. Please don't go over the basics. I have owned a power string trimmer for over twenty years. I don't remember the brand of string I used in the first place. Thanks.

I've used four different brands of string on the 15-inch trimmer without any problems. I would say you must be loading it wrong, maybe with the me al eyelet the string comes out of pinching he string, or something on the spool isn't tightened properly. Without seeing photos of the trimmer head or something that's just a guess, but something is damaging the string that isn't normal.

So which model do you own?
Do you have autoload or do you have to manually wind the string around the spool?
If it is the manually wound version...have you tried a prewound spool?

When you cleaned the head did you take the trimmer head apart?
If so...did you confirm the flange was reinstalled under the spool base?
Also was the washer and compression spring reinstalled between the spool base and the bump knob

If all else fails try to Install a new trimmer head

I have the 15" EGO trimmer model # ST1500F. It is only less than two years old. It is a manual load model. How would you load it wrong? You thread the string though the head and wind it in and it only loads one direction. I have only had the head apart enough to clear the string out. To get to the parts you mentioned I would have to take it apart. So those items are in. I'm going to buy the EGO line and see if that will work. Thank you.

Larry - I came here because I'm having exactly the same problem. I purchased a brand new ST1502SF trimmer a couple of weeks ago. Used up the spool of string that came with it, so loaded a new spool today. Ryobi brand, bought it at Home Depot last night. It broke INSIDE THE SPOOL the first three times I used it. As you said above - I've owned string trimmers for years, this isn't rocket science. And you can't "misload" the new spool. I use it 20-30 seconds, then the string breaks off and I have to take the head apart and reload the whole thing. What's up with that??? Have you found a solution?

No I haven't found a solution. Seems to be working with Husqvarna .095 Titanium Force string 280 ft. I at first bought the best at Home Depot. Speed Pro .095 string. That didn't last at all. Now I have 250 ft of string I can't use. The Husqvarna seems to be working okay. I'm not sure if that is a solution.

page 23-24 of your owners manual for figures

RELOAD THE CUTTING LINE, IF NECESSARY

NOTICE: When the cutting line breaks from the line outlet or the cutting line is not released when the trimmer head is tapped, you need to remove the remaining cutting line from the spool retainer and follow the steps below to reload the line.

  1. Remove the battery pack.
  2. Remove the cutting line from the spool retainer.
  3. Press the release tabs on the spool retainer and remove the spool retainer by pulling it straight out (Fig. 17 & 18).
  4. With one hand holding the spool base, use another hand to grasp the spool retainer and align the tabs on the spool retainer with the holes in the spool base; use your palm to press and rotate the spool retainer left and right until the tabs lock with the spool base. (Fig. 19 & 20).
  5. Following the instructions in “LINE REPLACEMENT” to reload the cutting line.

Then pages 22-23 of your owners manual for figures
LINE REPLACEMENT

  1. Remove the battery pack.
  2. Rotate the spool retainer in the arrow direction as necessary to align the LOAD line on the spool retainer with the eyelets in the spool base (Fig. 14).
  3. Cut one piece of cutting line 16 ft. (5m) long. Insert the line into the mounting hole, which is located inside the eyelet. Push until the end of the line comes out of the other side of the spool base. Pull the line from the other side until equal amounts of line appear on both sides of the spool (Fig. 15).
  4. Rotate the spool retainer in the direction of the arrow to wind 16the line onto the spool until approximately 5.5 in. (14cm) of line is showing on each side (Fig. 16).
  5. Push the spool retainer down while pulling on lines to manually advance the line and to check for proper assembly of the trimmer head.

I'm having the same problem and pushing those release tabs with one hand while pulling out the part is impossible for small arthritic hands. Is there some tool that would help. Is there a fix for this problem? Trimmer works fine for a short time and then the line disappears and it seems to "eat it up" way to rapidly.

Hi Dave,
I have a large pair of channel lock type pliers that I use to help get those tabs started. I think others have used large clamps.
String usage, at least in my experience, seems to be as much technique as it is the string. Hitting lots of hard objects will use up the string faster than not hitting those hard objects. As well, I've learned what the length of the string sounds like as it gets shorter so I'm sure to tap out some more string before it gets too short. The longer string definitely has a different sound than shorter string. I can also see the string as it is spinning so I can tell just how close to get to hard objects.
On my original 15" split shaft trimmer I've only ever used the EGO refill heads that come with string already wound on them. They work great and I don't risk somehow winding string incorrectly.

I finally have a method to get those tabs open just using a scree driver to pry one side at a time and lifting out the head. String problem persists and I lose 1/2 of the 16 ft each time as it breaks off inside the head. I'll look at the refill heads or another brand of line?

I found the string Ego uses to be too brittle to my liking. For the past couple of years I've been using Husqvarna Titanium Force line, which I find to be much more durable. The last time I bought it at Lowe's it was about $12 for a 250-foot roll, which at the rate I'm going will last me for years.

The Husqvarna is what I have found that last better also.
