You—the stationary power tool user—
hold the key to safety.
Read and follow these simple rules for best results
and full benefits from your machine. Used properly,
Wilton’s machinery is among the best in design and
safety. However, any machine used improperly can
be rendered inefficient and unsafe. It is absolutely
mandatory that those who use our products be
properly trained in how to use them correctly. They
should read and understand the Operating Instructions and Parts Manual as well as all labels affixed to
the machine. Failure in following all of these warnings
can cause serious injuries.
Machinery general safety warnings
1. Always wear protective eye wear when operating
machinery. Eye wear shall be impact resistant,
protective safety glasses with side shields which
comply with ANSI Z87.1 specifications. Use of
eye wear which does not comply with ANSI Z87.1
specifications could result in severe injury from
breakage of eye protection.
2. Wear proper apparel. No loose clothing or
jewelry which can get caught in moving parts.
Rubber soled footwear is recommended for best
footing.
3. Do not overreach. Failure to maintain proper
working position can cause you to fall into the
machine or cause your clothing to get caught —
pulling you into the machine.
4. Keep guards in place and in proper working
order. Do not operate the machine with guards
removed.
5. Avoid dangerous working environments. Do not
use stationary machine tools in wet or damp
locations. Keep work areas clean and well lit.
6. Avoid accidental starts by being sure the start
switch is “OFF” before plugging in the machine.
7. Never leave the machine running while unat-
tended. Machine shall be shut off whenever it is
not in operation.

General electrical cautions
This drill press should be grounded in accordance with the National Electrical Code and local codes and
ordinances. This work should be done by a qualified electrician. The saw should be grounded to protect the
user from electrical shock.
Wire sizes
Caution: for circuits which are far away from the electrical service box, the wire size must be increased in
order to deliver ample voltage to the motor. To minimize power losses and to prevent motor overheating and
burnout, the use of wire sizes for branch circuits or electrical extension cords according to the following table is
recommended.
AWG (American wire gauge) number
Conductor length 240 volt lines 120 volt lines

Safety Instructions for Drill Presses
handling any sharp objects or cutting tools. See
2. Drill press head and table shall be securely
locked to the column before operating the drill press.
This must always be checked prior to starting the
machine.
3. Always use the correct tooling. Tooling shall
always be maintained and properly sharpened. All
tooling must be run at the proper speeds and feeds
as they apply to the job. Use only recommended
accessories and follow those manufacturers instructions pertaining to them. Tooling shall be not be
forced in to any workpiece but fed according to the
proper specifications. Failure to follow these
instructions will not only ruin the tooling as well as
the machine, but can cause serious injury.

6. Always wear protective eye wear when operating,
servicing or adjusting machinery. Eyewear shall be
impact resistant, protective safety glasses with side
shields complying with ANSI Z87.1 specifications.
Use of the eye wear which does not comply with
ANSI Z87.1 specifications could result in severe
injury from breakage of eye protection. Figure B.

Operation and Set-up
Securing the Base
Wilton Model 2221VS and 2223VS drill presses
feature manual speed control. Models 2232AC and
2234AC have inverter speed control. This manual
contains procedures for both speed control versions.
The manual provides separate instructions when
differences in operation and maintenance exist.

The base of the drill press has four mounting slots;
two slots on both sides of the base. The drill press
should be level and rest solidly on the floor. Place
shims under the four mounting slots in the base as
needed to level the drill press.
When securing the base to the floor, apply even
torque to the fasteners to prevent distortion of the
