How do i remove the head to replace the string on a Murray M2500 trimmer?

SOURCE: remove string trimmer head on ry30120

Just the head or the attachment? The piece on the bottom, the bump knob can be unscrewed, sometimes are left hand thread. The attachments are screw off also I believe. Some may have two little pegs you push in and unattach it. Hope this helps. Please rate me

SOURCE: can not remove spool to replace string

If it's like my Ryobi, the alignment arrows are for feeding in string, not removing the spool. When aligned with the arrows, you should be able to insert two pieces of line into opposite sides of the housing. The ends of the line will come out of the spool next to a tiny hole. Put the end of each of the two lines into the holes, then pull the two lines from the outside. This will lock the ends of the line into the tiny holes in the housing. Now you can turn the housing by hand to wind the lines onto the spool. I think it will take about ten feet of line (on each side).

Alternatively, spin the bump stop out of the assembly. This holds the spool in, so when the bump stop is removed, the spool comes right out.

I hope this helps.

This was my problem as well when I initially purchased. After letting it sit for a week due to frustration...I tried again. I believe that the manual is wrong when it states that the winding is clockwise and could cause the teeth to eventually wear down. I watched the motion of the speed spool when I gently tugged on the line simulating the centrifugal force...there is no way that you can wind it clockwise and expect it to stay. I simply wound it COUNTER-CLOCKWISE to get the desired result. I finished trimming the lawn and had no more problems...except for learning that I cannot edge along concrete without the line wearing quickly.

You need a long skinny T25 torque driver (sold in a pack at Lowe's with 3 other sizes.)

Take off the 4 screws in the back to reveal the piston. Get a wooden dowel (or a wooden spoon if your wife isn't around) and stick it in to the piston to block it from spinning.

Now take that T25 and stick it in to the front pulley (cone shaped silver item that is preventing the housing from coming off) turn to the left and it should come off.

That should come off to reveal about a 1"x1.5" piece with a spring wrapped around it. That can also turn to the left and come off with an adjustable wrench or pliers.

Once that is off the housing should come away and you'll be able to get at the pull cord after removing 4 more T25 screws.

SOURCE: Ref: Stihl FS46 string trimmer. Broken Flex shaft.

Remove orange sheild,remove single screw holding head in shaft then grab head with pliers and twist side to side until complete head is free.You should then be able to grab part of shaft.On power head loosen screws {about one turn each} that hold two white case halves near trigger,I think there are four,then there is a single torx screw on the bottom of lower case half in the middle that must be taken out to allow tube to be removed.Romove flexshaft from top.Check 4 plastic burnt to flexshaft,if there is you must replace tube liner as well,usally around bent part of tube the liner will go bad.
