25-2 Bump Feed Trimmer Head 4002 710 2108 for Stihl FS55 FS55R FS56 FS56RC FS70 FS70R FS80 FS85 FS90 FS90R FS91R FS94R FS100RX FS110 FS111RX FS120 FS130 FS131 FS240, Replaces 4002 710 2191

I purchased this to replace my damaged head on my Stihl trimmer. Removing the old one and replacing with the new one was beyond easy and probably took a total of 3 minutes. Opening the unit up to refill trimmer was a bit stiff but opened up with a little extra pressure with a screw driver. I suspect over time this will loosen up as did the original equipment. Overall pleased with the replacement product and was pleased with the reasonable price.

Good article

Perfect fit for the Stihl FS250. Virtually the same as the original. Have used the item with the provided nylon line in heavy grass and the bump feed worked more smoothly than the 20-year old original.

This replacement head was cheaper than an OEM Stihl head and was a quick swap for my worn out head. This is the second replacement head I have bought. The first replacement head lasted 1 year before the bump feed button on the bottom wore flush with the rest of the head. I could not longer advance the line so it was time to replace it, again. The original Stihl head lasted 2 to 3 years.

I should have read the one star reviews more closely. My experience: Trimmer head installed ok, but the string broke at the eyelets within the first 5 minutes of use. The only way to fix the problem was to take the trimmer head apart. Then I learned you cannot install new string as advertised. You have to hand wind the new string then thread it through the eyelets and snap the head back together. Very challenging and disappointing. Lastly, the bump feed did not work well/at all, and the string broke again at the eyelets. After battling these issues for an hour, I gave up and contacted Amazon for a refund (item is non-returnable).

Good replacement!

This trimmer head fit my Stihl weedeater perfectly. It is made of thick plastic and appears to be really durable. The bump feed works just as it should. Really easy to take the old head off and install the new one. It probably took 2 or 3 minutes.

Works just as good as the OEM at a fraction of the cost. The only slight difference, which doesn’t affect fit, is the bump part sticks out a little further than the OEM, or my OEM original was just that far worn down.Installation is easy, there’s a small hole in the trimmers head (may be hidden and plugged with dirt and grass as in my picture), stick a small screwdriver in that hole, rotate the head by hand until you feel your screw driver catch. Unscrew the plastic head by hand, NOTE: It’s a “reverse thread”, meaning you turn it counter clockwise to loosen, clockwise to tighten. Hand tight is all you need, it tightens itself from the direction of its rotation.There’s a bolt head on the opposite side of the hole, its there so you can shoot some grease into the head. If you’re having to replace the part being reviewed its probably already past time to put some trimmer head grease in there.The couple reviews I read of people complaining this replacement “sticks” need to use a little common sense. The OEM ones could stick sometimes as well, the solution is simple. When you take it apart to wrap more string clean the dirt out of it for one thing. You can also take sand paper and smooth out around the bump mechanism and the inside of the hole on the outer cover, common sense, until it works smooth and freely.
