· lead from lead-based paints,
· crystalline silica from bricks and cement and other masonry products, and
· arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with approved safety equipment, always wear MSHA/NIOSH
approved, properly fitting face mask or respirator when using such tools.
GENERAL SAFETY RULES
READ AND UNDERSTAND ALL WARNINGS AND OPERATING INSTRUCTIONS BEFORE
USING THIS EQUIPMENT. Failure to follow all instructions listed below, may result in electric shock,
fire, and/or serious personal injury or property damage.
IMPORTANT SAFETY INSTRUCTIONS
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 per-
sonal safety is your responsibility. For additional information please visit our website www.deltamachinery.com.
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.

1. FOR YOUR OWN SAFETY, READ THE INSTRUCTION
MANUAL BEFORE OPERATING THE MACHINE.
Learning the machine’s application, limitations, and
specific hazards will greatly minimize the possibility of
accidents and injury.
2. WEAR EYE PROTECTION. ALWAYS USE SAFETY
GLASSES. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses are NOT safety
glasses. USE CERTIFIED SAFETY EQUIPMENT. Eye
protection equipment should comply with ANSI Z87.1
standards, hearing equipment should comply with
ANSI S3.19 standards, and dust mask protection
should comply with MSHA/NIOSH certified respirator
standards. Splinters, air-borne debris, and dust can
cause irritation, injury, and/or illness.
3. WEAR PROPER APPAREL. Do not wear loose cloth-
ing, gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Nonslip
footwear is recommended. Wear protective hair covering to contain long hair.

TION. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. Poorly maintained tools and machines can further damage the tool or machine and/or cause injury.
6. CHECK FOR DAMAGED PARTS. Before using the
machine, check for any damaged parts. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, and any other conditions that may
affect its operation. A guard or any other part that is
damaged should be properly repaired or replaced.
Damaged parts can cause further damage to the
machine and/or injury.
7. KEEP THE WORK AREA CLEAN. Cluttered areas and
benches invite accidents.
8. KEEP CHILDREN AND VISITORS AWAY. Your shop is a
potentially dangerous environment. Children and visitors can
be injured.
9. REDUCE THE RISK OF UNINTENTIONAL STARTING.
Make sure that the switch is in the “OFF” position
before plugging in the power cord. In the event of a
power failure, move the switch to the “OFF” position.
An accidental start-up can cause injury.
10. USE THE GUARDS. Check to see that all guards are in
place, secured, and working correctly to prevent injury.
11. REMOVE ADJUSTING KEYS AND WRENCHES
BEFORE STARTING THE MACHINE. Tools, scrap
pieces, and other debris can be thrown at high speed,

result.
13. USE RECOMMENDED ACCESSORIES. The use of
accessories and attachments not recommended by
Delta may cause damage to the machine or injury to the
user.
14. USE THE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. When using
an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage, resulting in loss of
power and overheating. See the Extension Cord Chart
for the correct size depending on the cord length and
nameplate ampere rating. If in doubt, use the next
heavier gauge. The smaller the gauge number, the
heavier the cord.
15. SECURE THE WORKPIECE. Use clamps or a vise to hold
the workpiece when practical. Loss of control of a
workpiece can cause injury.
16. FEED THE WORKPIECE AGAINST THE DIRECTION OF
THE ROTATION OF THE BLADE, CUTTER, OR ABRASIVE
SURFACE. Feeding it from the other direction will cause
the workpiece to be thrown out at high speed.
17. DON’T FORCE THE WORKPIECE ON THE MACHINE.
Damage to the machine and/or injury may result.
18. DON’T OVERREACH. Loss of balance can make you
fall into a working machine, causing injury.
19. NEVER STAND ON THE MACHINE. Injury could occur if the
tool tips, or if you accidentally contact the cutting tool.
20. NEVER LEAVE THE MACHINE RUNNING UNATTENDED.
TURN THE POWER OFF. Don’t leave the machine until it
comes to a complete stop. A child or visitor could be injured.
21. TURN THE MACHINE “OFF”, AND DISCONNECT THE

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
Delta Model 46-745 (115 volt) and Delta Models 46-746 and 46-765X (230 volt) operate on 50/60 HZ alternating current and provide a no-load spindle speed of 0-3200 RPM. Before connecting your tool to the power source, place the
switch in the “OFF” position. NOTE: The specifications on the motor will read “230 volt-3 phase”. This is correct and
is accomplished with a high frequency inverter. IMPORTANT: The motor cannot be run without the inverter.
Do not change input voltage. To do so will cause severe damage to the inverter.
GROUNDING INSTRUCTIONS
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.

TO PEDESTALS
Fig. 5
1. Remove the tailstock, headstock, and tool rest from the
lathe bed.
NOTE: See “ADJUSTING HEADSTOCK AND TAILSTOCK”
and “TOOL REST” for removal/installation instructions.
2. Set the pedestals exactly 58” apart (Fig. 5).
3. Because of the weight, use an assistant to place the lathe
bed on top of the pedestals. Align the holes in the lathe
bed with the holes in the tops of the pedestals (A) Fig. 6C.
4. Use the twelve 3/8-16 x 3/4” Hex Head bolts and lockwashers to attach the lathe bed to the pedestals.
NOTE: Level the machine by loosening the jam nut (A) Fig. 6C
and turning the adjusting nut (B). When leveling is complete,
tighten the jam nut (A).
To increase the height of the machine, place a 4" wide hardwood board (A) Fig. 6A between the pedestal (A) Fig. 6B and
the pedestal base (B) Fig. 6B.
NOTE: Place the 4" board under the pedestal, mark where the
holes are located, and drill the holes to allow longer carriage
bolts (not supplied) to come through.
In addition to showing the location of the bolts (A and B), Fig.
7 also shows that additional ballast can be added in the lathe
bed (C). Steel bars or other heavy material can be inserted
into the lathe bed to provide more weight.
NOTE: Use a good quality furniture wax on the lathe bed (C)
Fig. 7 to allow for smoother movement of the headstock, tool
rest, and tailstock, and to prevent rust.
ATTACHING END CAPS
Use the supplied hex wrench (B) Fig. 9 to attach the end caps
(A) Fig. 8 to both ends of the lathe with button head screws
(A) Fig. 9. Insert these through the end cap, then the lathe
bed. Secure with a flange nut (B) Fig. 8 .
NOTE: The flange nut can easily be dropped while attaching
the endcap. A metal flap (C) Fig. 6 will catch any fallen flange
nuts. However, if you folded the flap down to insert more
ballast, use a piece of cardboard or other material to cover the
hole during assembly.
