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.
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 of
forks or straps when lifting. Lifting equipment
must be properly rated for weight of drill press.
Locate the machine on a solid, level floor, preferably
concrete. Area should have good overhead lighting
and ventilation. (Refer to OSHA regulations for
specific information about using drill presses in
industrial environments.) The drill press should be
level and rest solidly on floor. Place shims below
base as needed to achieve level.
Exposed metal surfaces have been given a
protective coating. Remove this with a soft cloth and
a cleaner-degreaser or kerosene. Do not use
gasoline, paint thinner or acetone, as these may
damage painted surfaces. Do not use an abrasive
pad, as it may scratch polished surfaces.
Coat all machined surfaces with a light coat of oil to
inhibit rust.

5.1 Securing base

It is highly recommended that the drill press be
secured to floor. The drill press base has four
mounting slots; see Figure 4-1. When securing base
to floor, apply even torque to the fasteners to
prevent distortion of base.

6.0 Electrical Connections

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.
The JDP20EVST-230-PDF is pre-wired for single-
phase, 230-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. 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 access

The machine's electrical box has a switch interface.
Door will not open if main switch is ON.

6.2 GROUNDING INSTRUCTIONS

This tool must be grounded. 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 is equipped with
an electric cord having an equipment-grounding
conductor. If an electrical plug is to be used, the plug
must be inserted into an appropriate outlet that is
properly installed and grounded in accordance with
all local codes and ordinances.
Improper connection of the
equipment-grounding conductor can result in a
risk of electric shock. Check with a qualified
electrician or service person if you are in doubt
as to whether the outlet is properly grounded.
The conductor with insulation having an outer
surface that is green with or without yellow stripes is
the equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal.
Repair or replace
immediately.
If the drill press is to be hard-wired to a panel, make
sure a disconnect is available for the operator.
During hard-wiring of the machine, make sure the
fuses have been removed or the breakers have
been tripped in the circuit to which the drill press will
be connected. ALWAYS FOLLOW PROPER LOCK-
OUT/TAG-OUT PROCEDURES.
Model JDP20EVST-230-PDF is pre-wired for single
phase, 230 volt only. The machine can also be run
on 3-phase power by hooking up the ground, L1, L2
and 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 about
3 to 4 inches of the lead wires are exposed. Slide a
grommet onto the cord to be installed later in
electrical box hole, to prevent stress to power cord.
1. Bring the lead wires through hole in machine's
electrical box and connect as follows (refer to
Figure 6-1):
2. If your incoming power is single phase,
connect the two leads to L1 and L2, and the
green ground wire to the grounding screw.
3. If your incoming power is three phase, connect
the three leads to L1, L2 and L3, and the green
ground wire to the grounding screw.
