ladder to observe the column through top of pulley cover. 5.0 Set-Up and Assembly Inspect contents of crate for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until drill press is assembled and running properly. 6. Remove any fasteners holding drill press to pallet. Lift drill press with forklift or hoist with straps. (Note: Lifting point is beneath head and next to column.) Make sure coolant hose, handles, etc.
Make sure incoming current matches power requirements of the drill. When machine is connected properly, spindle turns clockwise in a conventional drilling rotation. If spindle does not turn clockwise, disconnect drill from power supply and reverse any two of the three power leads (except green ground wire). 6.2 GROUNDING INSTRUCTIONS This tool must be grounded.
8.1.1 For drilling (all models) Set switch to drill mode. Before starting motor, set end of drill against surface into which hole is to be drilled. Zero out indicator by turning knurled knob (J). Lock indicator setting at zero by tightening knob (K). Start motor and drill hole until indicator line reaches desired depth. 8.1.2 For tapping (JDP-20EVST models) Set depth stop in same manner as above. When quill is advanced, upper limit switch will be released for tapping.
8.3 Tool installation and removal 1. Disconnect machine from power source. 2. Thoroughly clean inside of spindle with a soft dry cloth. Also clean any taper or arbor to be used in the spindle. If these are not kept clean, taper or arbor will not “seat” properly in spindle and may drop out unexpectedly. 3. Place protective piece of scrap wood on table. 4. Raise table to approximately 8 to 10 inches below spindle. 5. Insert MT3 tool into spindle. 6.
9.2.2 Drilling feed 9.0 Operation The feed of a drill is governed by size of tool and the material drilled. Because feed rate partially determines rate of production and also is a factor in tool life, it should be chosen carefully for each job. In general, the most effective feeds will be found in the following ranges: 9.1 Operating precautions The following operating and safety precautions must be observed in order to avoid harm to operator or damage to drill press. 1.
10.3 Lubrication operation and exposure to potentially lethal voltage levels. See Table 4 for lubrication points and frequency. 1. Disconnect electrical power by setting drill press circuit breaker to OFF. 2. Loosen set screw and remove high/low shift lever. a. Periodically check oil level in sight gauge (A, Figure 10-1). 3. Remove screws and take off pulley cover. b. If level is below centerline of sight gauge, add oil. 4. Disconnect electrical wiring from junction box, and remove motor. c.
11.0 Troubleshooting JDP-20EVS series Drill Presses Trouble Spindle does not turn. Probable Cause Remedy Motor overload protector tripped. Press motor overload reset button. Circuit breaker tripped.
