Resumen del manual
See Figure 1. Extension Cords If you find it necessary to use an extension cord with the Model G1004/G1008, make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in the standard safety instructions to determine the minimum gauge for the extension cord. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn. Grounding In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool must be equipped with an electric cord having an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Figure 1. Grounded plug configuration. Potential for electrical shock hazard, this equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. If it is not, it will be necessary to run a separate 12 A.W.G. copper grounding wire from the outlet to a known ground. Under no circumstances should the grounding pin from any three- pronged plug be removed. Serious personal injury may occur. G1004/1008 Vertical Milling Machine -6 220V Operation Extension CordExtension Cords The Model G1004/G1008 has a motor which can be operated on a 220V single phase circuit. In order to operate at 220V it is necessary to rewire the motor connections (refer to the wiring diagrams at the back of this manual) and to add a 220V capable cord and plug. The style of plug you require will depend upon the type of service you currently have or plan to install. Figure 2 shows recommended plug styles. The motor will safely draw about 8 amps at 220V under load, therefore it should be connected to a circuit that is protected by a 15 amp fuse or circuit breaker. This should be satisfactory for normal use, while providing enough protection against motor damage caused by power surges. Grizzly recommends that the circuit you use should be dedicated, (i.e., the G1004 or G1008 should provide the only draw from that circuit). If frequent circuit failures occur when using the milling machine, contact our service department or your local electrical contractor. You are cautioned that equipment returned to us for service that shows evidence of being over-fused will be repaired or replaced totally at the customer’s expense, regardless of the present warranty status. Standard Locking Figure 2. Two typical outlet/plug configurations. We do not recommend the use of extension cords on 220V equipment. It is much better to arrange the placement of your equipment and the installed wiring to eliminate the need for extension cords. Should it be necessary to use an extension make sure the cord is rated Hard Service (grade S) or better. Grounding In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool must be equipped with an electric cord having an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Potential for electrical shock hazard, this equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious personal injury may occur. We have covered some basic electrical requirements for the safe operation of your Milling Machine. These requirements are not necessarily comprehensive. You must be sure that your particular electrical configuration complies with local and state codes. Ensure compliance by checking with your local municipality or a licensed electrician. -7-G1004/1008 Vertical Milling Machine SECTION 3: INTRODUCTION Commentary Grizzly Industrial, Inc. is proud to offer the Model G1004/G1008 Milling Machine.
