CAUTION

 

 

This Manual is published to assist experienced personnel on the operation, maintenance
and/or programming of Mazak machine tools.

All Mazak machine tools are engineered with a number of safety devices to protect
personnel and equipment from injury or damage.  Operators should not, however, rely
solely upon these safety devices, but should operate the machine only after fully
understanding what special precautions to take by reading the following documentation
thoroughly.

Do not attempt to operate or perform maintenance / repair on the machine without a
thorough understanding of the actions about to be taken.  If any question exists, contact
the nearest Mazak service center for assistance.

Certain covers, doors or safety guards may be open or removed to more clearly show
machine components.  These items must be in place before operating the machine.
Failure to comply with this instruction may result in serious personal injury or damage to
the machine tool.

This manual was considered complete and accurate at the time of publication, however,
due to our desire to constantly improve the quality and specification of all Mazak
products, it is subject to change or modification.
