Core Curriculum Module 00104-09 National Center for Construction Education and Research Slide 3 This module introduces three types of power tools: electric, pneumatic, and hydraulic. WARNING: If you have not completed the “BASIC SAFETY” module, stop here! You must complete the Basic Safety module first. Also, you must wear appropriate personal protective equipment when you operate any power tool or when you are near someone else who is operating a power tool. One of the most important rules about working with power tools is to always disconnect the power source for any tool before you replace parts such as bits, blades, or discs. Never activate the trigger lock on any power tool.
