Raising the Drill Head and Table
The drill press is shipped with the table and drill
head supported by wooden blocks near the
bottom of the column.
The head is raised to the operating position
using a strap and hoist, then secured to the
column by tightening the hex cap screw. The
table is raised to the desired position using the
crank handle. See
Adjustments section for more
information.
Electrical Connection
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.
Refer to the Wiring Diagram section for wiring
information.
The Drill Press is not supplied with a power
cord. To connect power, you may either install a
power cord with a UL/CSA listed plug, or hard
wire the machine directly to a service panel.
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.)
Manual control models: Model J-2221VS (1-
Phase) is pre-wired for 110 volts. Model J-
2223VS (3-Phase) is pre-wired for 220 volts.
NOTE: If rewiring the J-2221VS or J-2223VS for
alternate voltage, you must reconnect the wire
on the LED display accordingly (Figure 3), in
addition to changing the motor leads.

Inverter control models: Model J-2232AC (3-
Phase) is pre-wired for 220 volt only . The
machine can also be run on 1-Phase power by
hooking up the ground, L1 and L2 wires, as
explained below.
Model J-2234AC (3-Phase) is pre-wired for 440
volt only.
To wire the drill press with inverter control:
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 the control box hole, to prevent
stress to the power cord.
1. Bring the lead wires through the hole in the
side of the control box and connect as
follows (refer to Figure 3a):
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.
Figure 3a
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.
This drill press must be properly grounded.
Make sure the green ground wire is secured to
the grounding screw as described.
Make sure the power available matches the
power requirement of the drill. When the drill is
connected properly, the spindle turns clockwise
in a conventional drilling rotation. If the spindle
does not turn clockwise, disconnect the drill from
the power supply and reverse two of the three
power leads (except ground wire
green ).
