williamsl2355 Posted April 14, 2021 Report Share Posted April 14, 2021 Cutting up a rock with a diamond blade and out of nowhere it turned off. Troubleshooted and it wasn't the outlet or power cord. Read that it could be a brush arm or power switch? I have it taken apart right now and wanted a second opinion as to what I should do. thanks, Quote Link to comment Share on other sites More sharing options...
wingless Posted April 14, 2021 Report Share Posted April 14, 2021 Welcome to the forum. Follow normal diagnostic procedures to identify the problem. If the switch is receiving power from the cord, the the switch should be tested to verify power is provided to the output when the switch is turned on. The brushes may be removed and inspected. Also inspect the commutator on the armature while the brushes are out. Here is a parts listing for that tool. Quote Link to comment Share on other sites More sharing options...
