This section gives explanations and clarifications for the safety symbols you will see on your machine.

Hazard Symbols – Yellow Triangles

Symbol Description

Moving parts can entangle, trap, crush, and cut.

Keep all parts of your body away from machine parts when they move, or whenever motion is possible. Motion is possible when the power is on and the machine is not in EMERGENCY STOP.

Secure loose clothing, hair, etc.

Remember that automatically controlled devices can start at any time.

Do not touch rotating tools.

Keep all parts of your body away from machine parts when they move, or whenever motion is possible. Motion is possible when the power is on and the machine is not in EMERGENCY STOP.

Sharp tools and chips can easily cut skin.

Long tools are dangerous, especially at spindle speeds higher than 5000 RPM. The tools can break and eject from the machine.

Remember that machine enclosures are intended to stop coolant and chips. Enclosures may not stop broken tools or thrown parts.

Always check your setup and tooling before you start machining.

Materials can create hazardous dust or fumes during machining. The machine enclosure alone is not designed to contain dust or fumes.

Many materials are harmful, especially when airborne. This can include, but is not limited to: coolant mist, fine particles, fumes, and chips.

When necessary, use devices such as breathing apparatus and dust/fume removal systems. Read and understand the Safety Data Sheet (SDS) for the materials, and follow the safety recommendations.

Prohibited Action Symbols – Red Circles with Slash-Through

Symbol Description

Do not enter the machine enclosure when the machine is capable of automatic motion.

When you must enter the enclosure to complete tasks, press EMERGENCY STOP or power off the machine. Put a safety tag on the control pendant to alert other people that you are inside the machine, and that they must not turn on or operate the machine.

Do not machine ceramics.

Do not attempt to load tools with the spindle dogs misaligned with the cutouts in the toolholder V-Flange.

Do not machine flammable materials.

Do not use flammable coolants.

Flammable materials in particulate or vapor form can become explosive.

The machine enclosure is not designed to contain explosions or extinguish fire.

Do not use pure water as coolant. This will cause machine components to rust.

Always use a rust-inhibitive coolant concentrate with water.

Recommended Action Symbols – Green Circles

Symbol Description

Keep the machine doors closed.

Always wear safety glasses or goggles when you are near a machine.

Airborne debris can cause eye damage.

Make sure the spindle dogs are correctly aligned with the cutouts in the toolholder V-flange.

Note the location of the tool release button. Press this button only when you are holding the tool.

Some tools are very heavy. Handle these tools carefully; use both hands and have someone press the tool release button for you.

Informational Symbols – Black Circles

Symbol Description

Maintain the recommended coolant concentration.

A “lean” coolant mixture (less concentrated than recommended) may not effectively prevent machine components from rusting.

A “rich” coolant mixture (more concentrated than recommended) wastes coolant concentrate without further benefit over the recommended concentration.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
