Turn the knurled cap while holding the bottom and look thru the holes where the line exits and turn until you can see all the way thru . Then insert line around 10 ft. and pull them even on both sides then hold bottom and twist the knurled cap until desired lenth is reached...:-)
No, the Speed Feed High Capacity Trimmer Head is not recommended for use with the SRM-2100. The standard Speed Feed 400 is recommended. The part number is, #99944200907. The Speed Feed High Capacity is recommended for use with units that have a 25 cc engine or higher.
I put it on my Ryobi p2090 string trimmer so it will probably fit.
I’m unsure. I installed it on my Echo. I can recommend the product if it does fit your trimmer.
Yes it will fit the SRM-210, but it is not recommended for trimmers under 25cc. The SRM-210 has 21.3cc.
I put this on an echo srm225 so I would think it would work fine
