Milwaukee 2780-20 Trigger Assembly Replacement

Introduction

Is your Angle Grinder’s trigger not working? If so, here is the guide to fix the problem with a simple change of a trigger assembly. The trigger assembly is the one of the main components for the grinder. Basically, a squeeze of the trigger turns on the electric motor inside thus making the tool run. Without a fully functioning trigger, the machine would not be able to turn on. All you need to make the repair is a Torx T20 and a Torx T10 screwdriver to remove two different types of screws involved with this replacement.
