Mandatory Action
This symbol indicates an action that you must take to avoid a hazard.
On the Electrical Cabinet Door
WARNING! Electrocution Hazard. Points in the electrical cabinet contain high voltages, which can electrocute or shock you, causing death or serious injury. Even after the machine is powered off, electronic devices in the electrical cabinet can retain dangerous electrical voltages. Use caution when servicing the machine inside the electrical cabinet.
Lockout/Tagout. Before servicing the machine, you must power off the machine and use an approved lockout/tagout device to secure the Main Disconnect switch in the OFF position. Points in the electrical cabinet contain high voltages, which can electrocute or shock you, causing death or serious injury.
Next to the Main Disconnect
WARNING! Entanglement / Entrapment Hazard. The machine operates under automatic control — it can start at any time and crush, cut, entangle, or pinch body parts. Always keep clear of positions on the machine where unexpected or unintended machine motion could cause harm. Before operating this machine in any way, you must verify that all operators know the location of the machine's Emergency Stop button.
WARNING! Ejection Hazard. Fixtures, tooling, workpieces, or other loose items can become dangerous projectiles and can cause death or serious injury. Before operating this machine in any way, you must verify that you have appropriately secured all components.
WARNING! Fire Hazard. The machine and its enclosure are not designed to contain fire or explosions. Only use materials and coolants that are intended for the specific machining operation. Never use flammable or explosive items.Before operating the machine in any way, you must read all Safety Data Sheets (SDSs) for any workpiece materials, coatings, coolants, lubricants, and other consumables used.
WARNING! Inhalation Hazard. The machine and its enclosure do not protect you from airborne particulates. Chips, dust, and vapors from certain materials can be toxic or otherwise harmful. Before operating the machine in any way, you must read all Safety Data Sheets (SDSs) for any workpiece materials, coatings, coolants, lubricants, and other consumables used.
Personal Protective Equipment: Eyes. Prevent injury by always wearing protective safety eyewear. Before operating this machine in any way, you must verify that your eyewear is impact-resistant and rated for ANSI 787+.
Operator Knowledge. Before operating this machine in any way, you and all other operators must read and understand all instructions. If you don't, there's a risk of voided warranty, property damage, serious injury, or death.
On the Spindle Nose
WARNING! Crush Hazard. Moving parts can entangle, pinch, or cut you, causing death or serious injury. Before operating this machine in any way, you must verify that all body parts, long hair, and clothes are clear of the machine's extent of motion.
WARNING! Cut Hazard. Tools and swarf can cut you. Only hold tools by the tool holder. Before inserting or removing tools from the machine, you must verify that all motion is completely stopped.
Information Decals
Before operating the machine in any way, you must locate and become familiar with all installed information decals on the machine and equipment.

Understand that certain electrical components can retain dangerous electrical voltages, even after the machine is powered off and all power is removed from the system.
Understand that certain installation, maintenance, and troubleshooting procedures — for the machine and certain accessories — require access to or modification of wiring inside of the electrical cabinet. Only qualified electrical machinery technicians shall perform these procedures.
Confirm that the mains voltage conforms to requirements before connecting the machine.
For more information, see Electrical and Power Requirements.
Confirm that the machine installation meets all codes and regulations of your locality.
Confirm that electrical connections are performed by a certified electrician.
Lock the electrical cabinet door and remove the keys when the machine is not being serviced to prevent unqualified or unauthorized personnel from accessing the electrical cabinet.
Never operate the machine with the electrical cabinet door open.
Never reach into the electrical cabinet with the machine powered on.
Never modify the machine's electronics.
Never drill into the electrical cabinet.
Noise Exposure
CAUTION! Noise Exposure Hazard: If you expect the machine or the machining processes to exceed safe exposure limits, you must wear ear protection.
With the axes moving and the spindle rotating (but not cutting), the emission sound pressure level at the operator control station is 70 dB(A).
Emission sound pressure levels vary depending on the machining processes. Factors that influence the actual level of noise exposure may include:
Characteristics of the work room
Other sources of noise (like the number of machines, or other adjacent processes)
The permissible noise exposure level may vary between countries. You must evaluate of the hazard and risk based on your locality, and mitigate as necessary.
