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