6.2 Electrical cabinet access (JDP20VST only) 6.0 Electrical Connections To open electrical cabinet, press latch button and rotate latch to the left. A set of keys is provided for locking the cabinet door. Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury. 6.3 Voltage conversion (JDP-20VS1/3 only) The JDP-20VS-1 is pre-wired for single-phase, 115volt.
Adjustment knob (E1): Sets depth stop position. 7.0 Operating controls Lock knob (E2): Locks setting of depth stop. 7.1 JDP-20VS-1/3 controls Work light (F): Has separate on/off switch atop shade; flexible positioning. Refer to Figure 7-1. LED Display (A): Shows spindle RPM selected by speed control handwheel. Speed range switch (G): Two ranges. Middle position is neutral – spindle off. Must be set to high or low before front panel controls will function.
3. Set depth block to zero by turning knurled knob (E1). Then adjust block to desired depth of hole, and secure setting with knob (E2). 4. Start motor and drill hole until travel is restrained by indicator block. 7. To remove a tool: 8.1.2 For tapping (JDP-20VST only) 1. Set depth stop in same manner as above. 2. Set tapping mode (H). 3. When quill is advanced using downfeed handle (D), upper limit switch will be released for tapping.
8.6 Coolant pump (optional) SFM = 0.26 X RPM X Drill Diameter (in inches) The coolant system (not provided) should be filled with 2 gallons of a cutting coolant. Fill by pouring coolant into base of machine. Add coolant in the same manner when coolant is low. To drain coolant, remove hex cap screw located on lower backside of base. Follow all coolant manufacturer’s instructions for safety, mixing and disposal. RPM = 3.
9.2.4 Excessive speed/feed indicators 10.3 Lubrication A drill that splits up the web is evidence of too much feed or insufficient tip clearance at the center as a result of improper grinding. The rapid wearing away of the extreme outer corners of cutting edges indicates that speed is too high. A drill chipping or breaking out at the cutting edges indicates that either feed is too heavy or drill has been ground with too much tip clearance. See Table 4 for lubrication points and recommended frequency.
Note: Mount components near the lower edge of the spindle casting. DO NOT mount components above the line shown in Figure 111. 11.0 Coolant system (optional) Coolant pump system is optional. Contact your JET dealer for more information. See sect. 13.5.2 for stock number to order, depending upon your model of drill press. (Note: The following illustrations may or may not show your particular drill press.) 5. Note: On the JDP-20VST, coolant operation can be wired to the switch on the front panel. 11.
12.0 Troubleshooting JDP-20VS series Drill Press Trouble Spindle does not turn. Spindle noisy. Drill stalls. Poorly drilled holes. Motor overheating. Table binding, or cannot be raised.
