85.0 Set-Up and AssemblyInspect contents of crate for shipping damage.Report any damage immediately to your distributorand shipping agent. Do not discard any shippingmaterial until drill press is assembled and runningproperly.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. are clear offorks or straps when lifting. Lifting equipmentmust be properly rated for weight of drill press.Locate the machine on a solid, level floor, preferablyconcrete. Area should have good overhead lightingand ventilation. (Refer to OSHA regulations forspecific information about using drill presses inindustrial environments.) The drill press should belevel and rest solidly on floor. Place shims belowbase as needed to achieve level.Exposed metal surfaces have been given aprotective coating. Remove this with a soft cloth anda cleaner-degreaser or kerosene. Do not usegasoline, paint thinner or acetone, as these maydamage painted surfaces. Do not use an abrasivepad, as it may scratch polished surfaces.Coat all machined surfaces with a light coat of oil toinhibit rust.5.1 Securing baseIt is highly recommended that the drill press besecured to floor. The drill press base has fourmounting slots; see Figure 4-1. When securing baseto floor, apply even torque to the fasteners toprevent distortion of base.6.0 Electrical ConnectionsElectrical connections must bemade by a qualified electrician in compliancewith all relevant codes. This machine must beproperly grounded to help prevent electricalshock and possible fatal injury.The JDP20EVST-230-PDF is pre-wired for single-phase, 230-volt. It is not provided with an electricalplug; you may either attach a proper UL/CSA-listedplug, or “hardwire” the machine directly to a servicepanel. The machine can also be run on 3-phase,230V power. See sect. 6.2.The JDP20EVST-460-PDF is pre-wired for 3-phase,460-volt. It is not provided with an electrical plug;you may either attach a proper UL/CSA-listed plug,or “hardwire” the machine directly to a service panel.See sect. 6.2.6.1 Electrical box accessThe machine’s electrical box has a switch interface.Door will not open if main switch is ON.6.2 GROUNDING INSTRUCTIONSThis tool must be grounded. In the event of amalfunction or breakdown, grounding provides apath of least resistance for electric current to reducethe risk of electric shock. This tool is equipped withan electric cord having an equipment-groundingconductor. If an electrical plug is to be used, the plugmust be inserted into an appropriate outlet that isproperly installed and grounded in accordance withall local codes and ordinances.Improper connection of theequipment-grounding conductor can result in arisk of electric shock. Check with a qualifiedelectrician or service person if you are in doubtas to whether the outlet is properly grounded.The conductor with insulation having an outersurface that is green with or without yellow stripes isthe equipment-grounding conductor. If repair orreplacement of the electric cord or plug isnecessary, do not connect the equipment-groundingconductor to a live terminal.Repair or replace damaged or worn cordimmediately.If the drill press is to be hard-wired to a panel, makesure a disconnect is available for the operator.During hard-wiring of the machine, make sure thefuses have been removed or the breakers havebeen tripped in the circuit to which the drill press willbe connected. ALWAYS FOLLOW PROPER LOCK-OUT/TAG-OUT PROCEDURES.Model JDP20EVST-230-PDF is pre-wired for singlephase, 230 volt only. The machine can also be runon 3-phase power by hooking up the ground, L1, L2and L3 wires, as explained below.Model JDP20EVST-460-PDF (3-Phase) is pre-wired for 460 volt only.To wire the drill press:If using a power cord, strip back the cord until about3 to 4 inches of the lead wires are exposed. Slide agrommet onto the cord to be installed later inelectrical box hole, to prevent stress to power cord.1. Bring the lead wires through hole in machine’selectrical box and connect as follows (refer toFigure 6-1):2. If your incoming power is single phase,connect the two leads to L1 and L2, and thegreen ground wire to the grounding screw.3. If your incoming power is three phase, connectthe three leads to L1, L2 and L3, and the greenground wire to the grounding screw.
