Hol e cen t ers in Base (al l models)

The JET Model J-2221VS and J-2223VS drill presses feature manual speed control. Models J-2232AC and J-2234AC have inverter speed control. This manual contains procedures for both speed control versions. The manual provides separat e instructions when diff erences in operatio n and maintenance exist.

Refer to Figures 1 and 2 for key features of the drill p ress.

Operation and S et-Up

Securing the Base

The base of the drill press has four mounting slots; two s lots on both sides of the base. The drill pre s s shou ld b e le vel an d r e s t sol id ly on the floor. Place shims under the fo ur mount ing slots in the base as nee ded t o level the drill press.

When securing the base to t he floor, apply even torque to the fasteners to prevent distortion of the base.

Figure 1 Figure 2 Drill Press Features Drill Press Features (Manual Speed Control M odel) (Inverter Speed Control M odel )

Raising the Drill Head and Table

The dr ill pr ess is s hipped with the t able 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 t o the desired posit ion 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 prop erly grounded t o help prevent electrical shock and possible fatal injury.

To w ire the drill pres s with inverter c o ntrol: 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 bo x hole, to pr event stress to the power cord.

1. Bri ng 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 t he t w o leads to L1 a nd L2, and t he green ground wire to the grounding screw.

Refer to the Wiring Diagram section for wiring information.

The Drill Press is not supplied with a power cord. To connect pow er , y ou may either i nstall a power cord with a UL/CSA listed plug, or hard wire t he machine directly to a service panel.

If t he drill press is to be har d-wired to a pa nel, make sure a disconnect is available for the operator. (During hard-wiring of the machine, make sure t he fuses have bee n remo ved or t he breakers have been tripped in the circuit to which the dri ll p ress will be connect e d .)

Manual control models: Model J-2221VS (1Phase) is pre-wired for 110 volts. Model J2223VS (3-Phase) is pre- w ir ed f or 220 volts.

NOTE: I f r ewiring the J-2221 VS 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.

Figure 3

Inverter control models: Model J-2232AC (3Phase) is pre-wired for 220 volt only. The machine ca n also be r un o n 1-Phase power by hooking up the ground, L1 and L2 wires, as explained below.

Model J-2234AC (3-P hase) is pre- wired for 440 volt only.
