Tension spring for circular saw guard
easy fix, the saw needed some WD 40 to clean out years of dust that had gummed up the saw guide. Reoiled the pivot. Installed the spring. works great

Wouldn't cut on.

Time

Tools Used
Screwdriver, Pliers, Soldering iron
Old power cord showed significant fraying, so 99% probability that was source of problem. Replaced several minor springs, blade guard lever, and cord and strain reliever. Old cord attached with crimped connectors I did not have so cut and spliced and soldered to new cord. Insulated with shrink wrap.
Reassembled. Cleaned, repainted metal components, and looks nearly new (Makita). Saw originally belonged to my wife's grandfather. Lots of memories attached. Had passed onto me, then my son and finally quit on him. Sweet to have it running like new to keep the story going.

Hook one end of spring in hole on saw guard, stretch spring and hook other end on bar near top of casing. It fits a little differently depending on which direction you hook it in, so try it both ways to see which you prefer.
