What is the first step to changing blades and bits on power tools?

The first step to changing blades and bits on power tools is to disconnect the power. This is crucial for safety, ensuring that there is no accidental activation of the tool while you are handling it or making adjustments. By disconnecting the power source, whether it’s unplugging the tool or removing the battery (in cordless models), you eliminate the risk of injury that could occur from unexpected starts.

This safety protocol is a fundamental practice in power tool usage, emphasizing the importance of ensuring a secure working environment before performing any maintenance or changes. After the power is disconnected, you can then proceed to safely disassemble the tool, remove guards, or obtain new blades or bits without the risk of injury.
