Don’t skip this article! The AltMill 4×8 is a powerful and fast machine that can cause significant harm if you do not take the safety precautions as necessary.
Below are guidelines we strongly recommend to help prevent injury and protect your ears, eyes, limbs and phalanges for years to come.
Operation Guidelines
- Do not operate this machine in a compromised state, be alert and ready.
- Do not leave the machine unattended.
- Do not lean on or rest your body on any part of this machine, especially during jobs. The rack and pinion assembly is a major pinch point, stay away from that area.

- Never wear loose clothing and jewelry while operating the machine. Keep long hair away from all moving parts and wear appropriate footwear.
- Wear a good set of over-the-ear hearing protection or ear plugs to prevent hearing damage, since the 4×8 on its own or combined with a dust collection system can be quite loud

- A high quality dust mask or respiratory protection is needed to protect from inhaling particulates in the air, especially when using coolant, or when exposed to poor dust collection and ventilation. Some materials could be toxic or generate long-term health problems if inhaled, so look up the MSDS (material safety data sheet) of your material before you start cutting it.
- Cutting can kick-up a lot of dust and wood/metal chip, eye protection must be worn while the machine is running

- Carefully handle tools and materials. Cutting tools can shatter or cause damage if they’re not in good condition, and could cut you during handling.
- Be aware of safe disposal measures for your cutters and materials. Materials could ignite during cutting, within your dust collection system, or even spontaneously especially if mixed in with other chemicals or oils when disposed. Avoid using dust collection when cutting metals, as the hot metal could ignite existing sawdust in your disposal bin.
Enjoy your AltMill 4×8, and stay safe!
