    J630D 0.1 Safety of the machine The J630D machine has been designed in line with the present state of the art in engineering as well as generally recognized safety rules and regulations. It com- plies with the EU Machinery Directive. The X-radiation generated by the monitor is adequately shielded in accordance with statutory requirements.
  • Page 13: Measures To Be Taken In The Event Of Damage Incurred During Transit

    Any damage to the exterior or losses must be recorded in the appropriate manner on the freight note before the machine/system is accepted and reported immedi- ately to the insurer and K.Jung GmbH. In the event of damage that has occurred not being detected until the machine/ system is unpacked, leave the machine/system as you found it and notify the car- rier in writing that confirmation of the damage incurred is required.
  • Page 15: General Terms And Conditions Of Delivery

    The 6-month warranty period always commences on the day on which the risk passes to the customer. JUNG spare parts installed by other companies or by the customer are not subject to warranty or warranty claims.

    J630D 1. Safety 1.1 Symbols used in these Operating Instructions Draws attention to a potentially dangerous situation which could result in serious personal injury or death. Draws attention to a potentially dangerous situation which could result in minor personal injury. This symbol is also used if there is a risk of damage to the machine or equipment.
  • Page 19: Use For The Intended Purpose

    J630D 1.2 Use for the intended purpose The surface and profile grinding machine is a machine tool which is installed at a fixed location (stationary grinding machine). It is designed solely for machining workpieces with suitable grinding wheels. The grinding wheel and the workpiece are continuous path-controlled, in other words the grinding process is positively guided.
  • Page 21: General Safety Regulations

    J630D 1.3 General safety regulations No liability will be assumed by the manufacturer, and no claims for damages accepted, if the machine is operated incorrectly or if the safety regulations are ignored. The owner of the machine will be held solely responsible for any damage or injury that may ensue in this case.
  • Page 22: Important Information About The Operating Instructions

    J630D Dangerous situations can arise when the machine table of an open-type machine is extended laterally in the X-axis. You are liable to suffer bruising or other types of injury. You can avoid such situations by marking the danger zone on the floor on either side of the machine.
  • Page 23: Protective And Safety Equipment

    J630D Should any other national regulations exist in connection with accident prevention or environmental protection, these must be appended to the Operating Instruc- tions. Please also comply with any binding technical rules for safe and expert wor- king that are valid in the country in which the machine is used and at the place at which it is installed.
  • Page 24: Commissioning

    Aluminium and all alloys with at least 70 percent aluminium by weight, Magnesium and all alloys with at least 80 percent magnesium by weight. No liability will be accepted by K.Jung GmbH if you fail to comply, and all warranty claims will be refused.
  • Page 25: Disposal

    Report all malfunctions, damage, defects, leaks and any other form of imperfec- tion immediately to the person charged with overall responsibility for the machine. Repairs must always be carried out either by K.Jung GmbH or by another person or firm appointed and authorized by K.Jung GmbH.
  • Page 26 Failure to heed this warning could lead to wheel breakage. The diameter of the grinding wheel mount is specified on all wheel flanges from K.Jung GmbH. Always use flanges which are approved for your place of installation together with matching, approved grinding wheels. We cannot accept any liability for flanges supplied by other manufacturers.
  • Page 27: Magnetic Chucks

    J630D Make sure that all grinding wheels are properly balanced. Carry out a trial run for at least one minute at the maximum permissible speed be- fore you use a grinding wheel for the first time. Remember to cordon off the danger zone.
  • Page 28: Other Accessories / Work Equipment

    Please heed the Material Safety Sheet supplied by the oil manufac- turer. All liability and warranty claims vis-à-vis K.Jung GmbH are excluded. 1.3.11 Other accessories / work equipment As the owner of the machine, you must fit an extraction device if the quantity of dust and/or smoke and/or mist produced during grinding is such that it could rep- resent a health hazard.
