SAFETY PRECAUTIONS
GENERAL Service Personnel: Always be alert and practice all necessary safety rules and precautions when servicing this equipment. Always observe the following safety precautions: • Always disconnect the power source before attempting maintenance on or servicing the machine. • Always turn the main disconnect switch to the OFF position before removing or servicing any circuit boards, switches, fuses, cables, and components within the Power and/or CNC control cabinets. • Post a warning on or near the disconnect switch telling others not to turn ON the power to the machine whenever working in an area away from the switch. • If it becomes necessary to make any tests or checks with live circuits, be extremely careful and follow all established safety practices. Remember, the line side of the disconnect switch may be hot even though the switch is in the OFF position.
704-0001-564 July 1990 KM3 KM3P Revision A
This manual is divided into sections that are separated by colored divider pages. Each section contains part drawings to help identify electro-mechanical parts for the KM3/3P machining centers. The part drawings can also be used to determine the source of machine malfunction. The parts displayed in this manual were developed to meet specific production requirements. The use of any non-recommended replacement parts may damage the machine or reduce production quality. Hurco has an ongoing program to further improve existing parts. Many of these improvements cannot be detected by visual examination (comparing old and new parts). For these reasons, it is extremely important that only recommended replacement parts be used.
Important
Always wear the static control wrist strap when working inside the CNC control cabinet. Avoid flexing the printed circuit boards (PCBs, also called printed wiring boards or PWBs) whenever they are handled, or removed, or inserted in the machine. Hairline cracks in the printed circuit etching may result from rough handling, causing problems that are often intermittent and difficult to find. Avoid touching the components (devices) installed on a printed circuit board because they may become damaged by static electricity. NOTICE Hurco products should be used only for the purpose and in the manner intended by their original design. It is recommended that no modifications be made to this product. Any modifications of this product will void any expressed or implied warranty.
