Work Safe and Stay Safe
Whenever using tools, always think safety first, there is nothing more important than your personal safety and if tools (both hand and power) are used incorrectly you can hurt yourself (in the extreme - fatally).
Always follow equipment and workshop instructions, including the use of recommended personal protection equipment. Accidents only take a moment to occur but can take a lifetime to recover from. You are responsible for your safety so remember Work Safe and Stay Safe.
