I'm trying to replace the entire bump head assembly on a ST1500-S trimmer. I depressed the release tabs and removed the spool retainer assembly, but I'm unable to remove the bump head so I can unscrew the nut. Any suggestions?
Blue Angel, Thank you very much for the suggestion. I tried pulling the bump knob, but it wouldn't pop off. I then tried using a flat head screw driver to pop it off and that worked. The bump knob has 4 tabs on the interior, so I needed more leverage to pop the knob off.
This is good info as my bump head is not working. I need to check the spring out and most likely replace. Ego's video made removal look so simple and I didn't know if my model was different than the one shown.
