Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there
are certain hazards involved with the operation of the product. Using the machine with respect and caution will
considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored,
personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards,
goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make
up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop.
If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your
personal safety is your responsibility.
This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not
be modified and/or used for any application other than that for which it was designed. If you have any questions relative
to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should
be performed on the product.

2. Grounded, cord-connected machines intended for use
on a supply circuit having a nominal rating less than 150
volts:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A,the
machine will have a grounding plug that looks like the plug
illustrated in Fig. A. A temporary adapter, which looks like
the adapter illustrated in Fig. B, may be used to connect
this plug to a matching 2-conductor receptacle as shown
in Fig. B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box. Whenever
the adapter is used, it must be held in place with a metal
screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected machines:
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 machine is
equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must
be plugged into a matching outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in risk of electric shock. 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.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely
understood, or if in doubt as to whether the machine is
properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as shown in
Fig. A.
Repair or replace damaged or worn cord immediately.
POWER CONNECTIONS
MOTOR SPECIFICATIONS
Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source,
make sure the switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.

Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire
extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s
plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct
gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number,
the heavier the cord.
EXTENSION CORDS
FOREWORD

workpiece. Then tighten screw (B).
Fig. 26
SLIDING FIT BETWEEN
HEAD AND COLUMN
A dovetail gib (A) Fig. 27, is provided on the rear of the
head to insure a good sliding fit between the head and
the column when the head is raised and lowered.
Adjustment is made by loosening the two screws (B) and
turning adjusting screws (C). Then tighten two screws
(B). NOTE: Correct adjustment is when a good snug
sliding fit is obtained without any side movement
between the gib and the column. This adjustment
should not be too tight that it restricts the sliding
movement or too loose that it affects accuracy. Fig. 27
OPERATIONS
1. Make sure that chisels and bits are sharp.
2. Fig. 28, illustrates a typical mortising operation.
Note that the opening (A) in the chisel is to the right. This
means that after the first cut is complete, the workpiece
should be moved to the right for subsequent cuts. This
allows chips to escape freely through the opening in the
chisel.
3. Make sure the workpiece is held firmly against the
fence when cutting and that the holddown (B) Fig. 28, is
properly adjusted. The rate of penetration of the chisel
must be fast enough to prevent burning at the tip of the
bit, but not too fast as to stall the motor. You may en-
counter smoke from the bit or material once the chisel has
engaged the material. The smoke created is a natural
operating occurrence in hollow chisel mortising and is
caused by material chip friction and the resins in the
stock being burned off. Bluing of the chisel after initial
use is not indicative of a dull chisel, but a combination
of friction and resin buildup on the cutting faces of the
chisel. A dull chisel can be detected by the amount of
excess force required to complete a cut.
4. When performing a through mortise, a thin piece of
wood should be placed between the workpiece and the
table. This prevents “chip-out” at the bottom of the
mortise.
5. Fig. 29, illustrates the mortising operation
completed.

ROTATING COLUMN 180
DEGREES
The column (A) Fig. 31, can be rotated 180 degrees, as
shown, if it is desired to cut workpieces off the table. To
rotate the column, remove four screws, two of which are
shown at (B), rotate column (A) 180 degrees and replace
the four screws (B).
THE BASE MUST BE SECURED TO A
SUPPORTING SURFACE.
Fig. 31
USING BITS WITH EXTRA
LONG SHANKS
When using bits with extra long shanks, it will be
necessary to remove the extension (A) Fig. 32. This can be
done by inserting screwdriver into center hole of motor
end cap (B) Fig. 33, and into slot (E), in end of armature
shaft. Then using chuck key, unscrew and remove chuck
(C) Fig. 32, and extension (A). Remove extension (A)
from chuck (C) and replace chuck (C) on end of motor
shaft. The chisel spacer may also be used when using
chisels with extra long shanks. Place the chisel spacer
(D) Fig. 34 on the chisel shank (F) and insert chisel into
chisel holder and tighten chisel holder securely.
