Safety
- Make sure to use your mill on a flat and stable surface.
- Work in a clean and well-lit area
- Keep a vacuum nearby for chip cleanup
Work Area Safety
- Do not leave the milling machine unattended while in use.
- Prior to operation, make sure the collet and tool are secure and remove the wrenches and other tools from inside the milling machine.
- Do not use the milling machine if its safety windows are cracked.
Personal Safety
Safety
- Make sure to turn off the milling machine before unplugging or plugging back in. Do not unplug by pulling on the power cord.
- Do not use the milling machine if the power cord is damaged.
- Do not abuse the power cord. Do not twist, bend, scrape, pull, pinch, or put a heavy object on it. Keep the cord away from heat, sharp edges, and oil.
Electrical Safety

- As with any power tool, do not use the milling machine if you are tired, distracted, or otherwise impaired.
- Do not operate the milling machine with damaged or dull bits.
- Use the milling machine’s Emergency Stop button to immediately stop the machine when necessary.
Machine & Tool Safety
Safety
- Ensure that the milling machine is clear of debris before and after operation. Use a brush to clean metal debris, as vacuum-cleaning metal shavings could cause a fire in the vacuum cleaner.
- A vacuum may be used to clean other material debris. Never clean the milling machine while in use.
