Wichman Posted Monday at 06:19 PM Report Share Posted Monday at 06:19 PM (edited) In no particular order Motor brushes glazed, remove and very gently scrape the surface. The face of the brush should be dull not shiny. Brushes wornout Brush springs worn, not making good contact (If used) Extension cord wires to small for load Shop wiring tool light for load (Very rare, but I've seen it) Copper in house or shop wiring "crystalized" Power switch packed with sawdust Defective speed controller Edited Monday at 06:21 PM by Wichman OCtoolguy and Be_O_Be 2 Quote Link to comment Share on other sites More sharing options...
