IMPORTANT: Do not operate this machine until you have read all warnings, cautions, and instructions

CAUTION: The sample programs in this manual have been tested for accuracy, but they are for illustrative purposes only. The programs do not define tools, offsets, or materials. They do not describe workholding or other fixturing. If you choose to run a sample program on your machine, do so in Graphics mode. Always follow safe machining practices when you run an unfamiliar program. 

All CNC machines present hazards from rotating cutting tools, belts and pulleys, high voltage electricity, noise, and compressed air. When you use CNC machines and their components, you must always follow basic safety precautions to reduce the risk of personal injury and mechanical damage.

The work area must be adequately illuminated to allow clear view and safe operation of the machine. This includes the operator work area and all areas of the machine that might be accessed during maintenance or cleaning.Adequate illumination is the responsibility of the user.

Cutting tools, workholding, workpiece and coolant are beyond the scope and control of Haas Automation, Inc. Each of these potential hazards associated with it (sharp edges, heavy lifting considerations, chemical composition, etc) and it is the responsibility of the user to take appropriate action (PPE, training, etc).

Cleaning of the machine is required during normal use and prior to maintenance or repair. Optional equipment is available to aid cleaning such as washdown hoses, chip conveyors and chip augers. Safe use of this equipment requires training and might require appropriate PPE and is the responsibility of the user.

This operator’s manual is intended as a reference guide and is not to be the sole source of training. Complete operator training is available from the authorized Haas distributor.

Read Before Operating

DANGER: Do not enter the machining area any time the machine is in motion, or at any time that machine motion is possible. Severe injury or death may result. Motion is possible when the power is on and the machine is not in [EMERGENCY STOP].

Basic safety:

  • This machine can cause severe bodily injury. 
  • This machine is automatically controlled and may start at any time.
  • Consult your local safety codes and regulations before you operate the machine. Contact your dealer if you have questions about safety issues.
  • It is the machine owner’s responsibility to make sure that everyone who is involved in installing and operating the machine is fully acquainted with the operation and safety instructions provided with the machine, BEFORE they work with the machine. The ultimate responsibility for safety rests with the machine owner and the individuals who work with the machine. 
  • Use appropriate eye and ear protection when you operate the machine. 
  • Use appropriate gloves to remove processed material and to clean the machine. 
  • Replace windows immediately if they are damaged or severely scratched. 
  • Keep the side windows locked during operation (if available).

Electrical safety:

  • The electrical power must meet the required specifications. Attempting to run the machine from any other source can cause severe damage and will void the warranty. 
  • The electrical panel should be closed and the key and latches on the control cabinet should be secured at all times, except during installation and service. At those times, only qualified electricians should have access to the panel. When the main circuit breaker is on, there is high voltage throughout the electrical panel (including the circuit boards and logic circuits) and some components operate at high temperatures; therefore, extreme caution is required. Once the machine is installed, the control cabinet must be locked, with the key available only to qualified service personnel. 
  • Do not reset a circuit breaker until the reason for the fault is investigated and understood. Only Haas-trained service personnel should troubleshoot and repair Haas equipment. 
  • Do not press [POWER UP] on the control pendant before the machine is fully installed.

Operation Safety:

DANGER: To avoid injury verify that the spindle has stopped turning before opening the doors. In the event of a loss of power the spindle will take much longer to coast to a stop.

  • Do not operate the machine unless the doors are closed and the door interlocks are functioning correctly.
  • Check for damaged parts and tools before you operate the machine. Any part or tool that is damaged should be properly repaired or replaced by authorized personnel. Do not operate the machine if any component does not appear to be functioning correctly.
  • When a program runs, the tool turret can move rapidly at any time.
  • Improperly clamped parts machined at high speeds/feeds may be ejected and puncture the enclosure. It is not safe to machine oversized or marginally clamped parts.

CAUTION: Manual or Automatic closing of the enclosure doors is a potential pinch point. With Auto Door, the door may be programmed to close automatically, or by pressing the door open/close button on the operators pendant. Avoid putting hands or appendages in the door while closing either manually or automatically.

Release of person trapped in the machine:

  • No person should ever be located inside the machine during operation. 
  • In the unlikely event that a person is trapped inside the machine the emergency stop button should be immediately be depressed and the person removed. 
  • If the person is pinched or entangled the machine should be powered off; then the machine axes can be moved by use of a large external force in the direction required to free the person.
Recover from a jam or blockage:
  • Of the chip conveyor - Follow the cleaning instructions on the Haas service site (go to www.haascnc.com click on the Service tab). If necessary, close the doors and reverse the conveyor so the jammed part or material is accessible, and remove. Use lifting equipment or get assistance for lifting heavy and awkward parts. 
  • Of a tool and material/part - Close the doors, press [RESET] to clear and displayed alarms. Jog the axis so the tool and material are clear.
  • If the alarms do not reset or you are unable to clear a blockage, contact your Haas Factory Outlet (HFO) for assistance.

 

Follow these guidelines when you work with the machine:

  • Normal operation - Keep the door closed and guards in place (for non-enclosed machines) while the machine operates.
  • Part loading and unloading -- An operator opens the door, completes the task, closes the door, and then presses [CYCLE START] (starting automatic motion).
  • Machining job set-up -- When set-up is complete, turn the set-up key to lock out set-mode and remove the key.
  • Maintenance / Machine Cleaner-- Press [EMERGENCY STOP] or [POWER OFF] on the machine before you enter the enclosure.
  • Tool loading or unloading -- A machinist enters the machining area to load or unload tools. Exit the area completely before automatic movement is commanded (for example, [NEXT TOOL] , [TURRET FWD] , [TURRET REV] ).
Chuck Safety:
 
DANGER: Improperly clamped parts or oversized parts may be ejected with deadly force.
  • Do not exceed the chuck’s rated speed. Higher speeds reduce chuck clamping force.
  • Unsupported barstock must not extend outside the drawtube.
  • Grease the chuck weekly. Follow the chuck manufacturer’s instructions for regular service.
  • Chuck jaws must not protrude beyond the diameter of the chuck.
  • Do not machine parts larger than the chuck.
  • Follow all of the chuck manufacturer’s warnings regarding the chuck and workholding procedures.
  • Hydraulic pressure must be set correctly to securely hold the work piece without distortion.
  • Improperly clamped parts at high velocity may puncture the safety door. You must reduce the spindle speed to protect the operator when performing dangerous operations (e.g. turning oversized or marginally clamped parts).

Periodic inspection of machine safety features:

  • Press any of the Emergency Stop buttons to verify all motion is stopped and a 107 EMERGENCY STOP Alarm is displayed.
  • A monthly inspection of each Emergency Stop button should be performed.
  • Inspect door interlock mechanism for proper fit and function.
  • Inspect safety windows and enclosure for damage or leaks. 
  • Verify all enclosure panels are in place.

Door Safety Interlock inspection:

  • Inspect the door interlock, verify the door interlock key is not bent, misaligned, and that all fasteners are installed.
  • Inspect the door interlock itself for any signs of obstruction or misalignment. 
  • Immediately replace an components of the Door Safety Interlock system that do not meet this criteria.

Door Safety Interlock verification:

  • With the machine in run mode, close the machine door, run the spindle at 100 RPM, pull the door and verify the door does not open.

Machine Enclosure and Safety Glass inspection and testing:

Routine Inspection:

  • Visually inspect the enclosure and safety glass for any signs of distortion, breakage or other damage. 
  • Replace the Lexan windows after 7 years or if they are damaged or severely scratched. 
  • Keep all safety glass and machine windows clean to allow proper viewing of the machine during operations. 
  • A daily visual inspection of the machine enclosure to verify all panels are in place should be performed.

Testing of machine enclosure:

  • No testing of the machine enclosure is necessary.

Parts Catcher Safety

  • DANGER: The Parts Catcher Operates Automatically.
  • Never put your hand or arm inside the parts catcher chute.
