after thoroughly cleaning, spray a little dry lube on the spring & slider grooves inside the head, Install slider springs, install slider (Making sure the spring tabs on slider are over the top of the slider springs), while holding slider & springs in, attach the C clip to shaft that holds the slider in place, but lets it freely slide. Then install plunger spring & plunger. Hold plunger down while attaching the E clip onto the shaft. push plunger & watch slider move to one side, then back when plunger comes back up. Basically, verify operation. If all is good, Install spool & bump knob. Then install trimmer line as normal...
