Safety Warnings and Guidelines
1. Be sure to carefully follow provided machine assembly instructions before machine use to ensure operator
safety.
2. All wires must be appropriately positioned before beginning the operation of this machine. Cutting a “live”
wire may cause exposed metal parts of the routing/trimming tool to become electrified and shock the
operator.
3. Ensure the machine is placed on a flat surface and in a well-ventilated space before operation.
4. Always wear eye protection during machine operation.
5. Always wear hearing protection during extended machine operation based on proximity to machine.
6. Materials may release chemicals that are toxic or unsafe to inhale when cut. Always check the Material Safety
Data Sheet (MSDS) of the material in question before cutting. Always cover exposed skin and wear
appropriate airway protection (e.g. dust mask/respirator) specific to the material used and its application.
7. Any workpiece must be appropriately secured before starting a cutting routine by clamps or other practical
securing method. Holding the material by hand or employing any other unstable form of securing will lead to
unsafe loss of machine control.
8. Cutting bits used for the Mill One should be used at the discretion of the user. Bits are sharp and can crack
and break without notice so appropriate care should be taken by the user while manipulating and installing
them. Carefully check bits for cracks or damage before operating the machine and replace any cracked or
unfit bits immediately.
9. Carefully inspect any consumable material before use on the machine, any unforeseen inconsistency in
material hardness or material quality may cause damage to the machine.
10. Keep away from all moving parts during machine operation.
11. Before beginning a cutting job, ensure the router/trimmer runs properly. Immediately disable the tool if
visible vibration or wobble occurs. This might indicate a damaged tool or an improperly installed bit.
12. Make sure the bit in not contacting the workpiece before the router/trimmer tool is turned on.
13. Do not leave the machine running unattended, the machine should only be operated with the operator
present.
14. Do not touch the cutting bit immediately after use. It may be hot and could burn the operator.
15. Use bits that are appropriate to the material and cutting speed used.
