Safety Considerations
Always use common sense when using a power tool. Review the safety
instructions that came with your lathe. Besides the general safety rules for any
power tool, the following are specific considerations for the mini lathe.
Your mini lathe is just that, a
mini,
or small lathe. Don’t attempt jobs that
are beyond its capacity.
Check the work piece after you place it in the chuck or other work holding
device. Be sure it is secure before turning on the lathe.
Don’t wear loose clothing or jewelry when operating the lathe.
