INTRODUCTION
About This Machine
Foreword
"The screw cutting engine lathe is the oldest and
most important of machine tools and from it all
other machine tools have been developed. It was
the lathe that made possible the building of the
steamboat, the locomotive, the electric motor, the
automobile and all kinds of machinery used in
industry. Without the lathe our great industrial
progress of the last century would have been
impossible." —How To Run a Lathe, 15th
Edition, South Bend Lathe.
The lathe represented in this manual is a
modern day version of the screw cutting lathes
that trace their roots back to the 1700's, which
were themselves technological improvements of
the bow lathe that can be traced back thousands
of years to the ancient Egyptians.
Now, almost 300 years later, these modern
"screw cutting" lathes are not just a piece of
refined machinery, but a culmination of human
ingenuity and knowledge embodied into the
design and synergy of thousands of interworking
parts—some of which represent the life's work
and dreams of many inventors, mechanical
engineers, and world-class machinists—including
the likes of Leonardo da Vinci, Henry Maudsley,
and the founders of South Bend Lathe, John and
Miles O'Brien.
And now the torch is passed to you—to take
the oldest and most important type of machine
tool—and carry on the tradition. As the operator
of a South Bend Lathe, you now join the ranks
of some very famous and important customers,
such as Henry Ford, who used the machines he
purchased to help him change the world.
Features
These Heavy 13® Gearhead Lathes are packed
with standard features and equipment, such
as a complete coolant system, easy-to-clean
chip drawer, one-shot way lubrication system,
included steady and follow rests, chuck guard,
adjustable work lamp, foot brake, powered
cross feed, 3- and 4-jaw chucks, faceplate, and
premium Allen-Bradley contactors, thermal
relays, and fuse system.
Spindle speeds are controlled by convenient
headstock levers, which allow the operator to
quickly set the spindle speed within the available
range of 80–2000 RPM.
The beds of these lathes are constructed with
Meehanite castings that are hardened and
precision-ground in the traditional three V-way
prismatic design—long used on South Bend
Lathes for its accuracy, durability, and rigidity.
The headstocks feature quick-change gear levers
and the carriages include an adjustable clutch
that disables automatic carriage feed when it
contacts the included feed stop or in the event of
a crash.
To further ensure a high degree of accuracy,
these lathes are equipped with Japanese spindle
bearings. The spindles are D1-5 camlock with an
MT#5 taper and 1.57" bore. The tailstocks have
an MT#3 taper and 4.5" of quill travel.
Capabilities
This Heavy 13® Gearhead Lathe is built for daily
use in a busy industrial setting. Loaded with
many nice features and high-precision parts, this
lathe excels at making fine tools, dies, thread
gauges, jigs, and precision test gauges—however,
it is by no means delicate. Thick castings, heavy
weight, and quality construction throughout
provide the necessary brawn for demanding
production and manufacturing tasks.

workpieces must be turned at slow speeds.
Always use the appropriate feed and speed
rates.
Chuck Key Safety. A chuck key left in the chuck
can become a deadly projectile when the
spindle is started. Always remove the chuck
key after using it. Develop a habit of not
taking your hand off of a chuck key unless it
is away from the machine.
Safe Clearances. Workpieces that crash into
other components on the lathe may throw
dangerous projectiles in all directions,
leading to impact injury and damaged
equipment. Before starting the spindle,
make sure the workpiece has adequate
clearance by hand-rotating it through its
entire range of motion. Also, check the tool
and tool post clearance, chuck clearance, and
saddle clearance.
Clearing Chips. Metal chips can easily cut bare
skin—even through a piece of cloth. Avoid
clearing chips by hand or with a rag.Use a
brush or vacuum to clear metal chips.
Stopping Spindle by Hand. Stopping the spindle
by putting your hand on the workpiece
or chuck creates an extreme risk of
entanglement, impact, crushing, friction, or
cutting hazards. Never attempt to slow or
stop the lathe spindle with your hand. Allow
the spindle to come to a stop on its own or
use the brake.
Crashes. Aggressively driving the cutting tool
or other lathe components into the chuck
may cause an explosion of metal fragments,
which can result in severe impact injuries
and major damage to the lathe. Reduce
this risk by releasing automatic feeds after
use, not leaving lathe unattended during
operation, and checking clearances before
starting the lathe. Make sure no part of the
tool, tool holder, compound rest, cross slide,
or carriage will contact the chuck during
operation.
Long Stock Safety. Long stock can whip violently
if not properly supported, causing serious
impact injury and damage to the lathe.
Reduce this risk by supporting any stock
that extends from the chuck/headstock more
than three times its own diameter. Always
turn long stock at slow speeds.
Securing Workpiece. An improperly secured
workpiece can fly off the lathe spindle with
deadly force, which can result in a severe
impact injury. Make sure the workpiece is
properly secured in the chuck or faceplate
before starting the lathe.
Chucks. Chucks are very heavy and difficult to
grasp, which can lead to crushed fingers or
hands if mishandled. Get assistance when
handling chucks to reduce this risk. Protect
your hands and the precision-ground ways
by using a chuck cradle or piece of plywood
over the ways of the lathe when servicing
chucks. Use lifting devices when necessary.
Coolant Safety. Coolant is a very poisonous
biohazard that can cause personal injury
from skin contact alone, especially when it
gets old or has been well-used. Incorrectly
positioned coolant nozzles can splash on
the operator or the floor, resulting in skin
exposure or a slipping hazard. To decrease
your risk, change coolant regularly and
position the nozzle where it will not splash
or end up on the floor.
Tool Selection. Cutting with an incorrect or
dull tool increases the risk of accidental
injury due to the extra force required for
the operation, which increases the risk of
breaking or dislodging components that
can cause small shards of metal to become
dangerous projectiles. Always select the
right cutter for the job and make sure it is
sharp. Using a correct, sharp tool decreases
strain and provides a better finish.

SAFETY
Additional Chuck Safety
Entanglement. Entanglement with a rotating
chuck can lead to death, amputation, broken
bones, or other serious injury. Never attempt
to slow or stop the lathe chuck by hand,
and always roll up long sleeves, tie back
long hair, and remove any jewelry or loose
apparel BEFORE operating.
Chuck Speed Rating. Excessive spindle speeds
greatly increase the risk of the workpiece or
chuck being thrown from the machine with
deadly force. Never use spindle speeds faster
than the chuck RPM rating or the safe limits
of your workpiece.
Using Correct Equipment. Many workpieces can
only be safely turned in a lathe if additional
support equipment, such as a tailstock or
steady rest, is used. If the operation is too
hazardous to be completed with the lathe or
existing equipment, the operator must have
enough experience to know when to use a
different machine or find a safer way. If you
do not have this experience, seek additional
training (outside of this manual) from
experienced lathe operators, books, or formal
classes
Trained Operators Only. Using a chuck
incorrectly can result in workpieces coming
loose at high speeds and striking the
operator or bystanders with deadly force.
To reduce the risk of this hazard, read
and understand this document and seek
additional training from an experienced
chuck user before using a chuck.
Chuck Capacity. Avoid exceeding the capacity
of the chuck by clamping an oversized
workpiece. If the workpiece is too large to
safely clamp with the chuck, use a faceplate
or a larger chuck if possible. Otherwise, the
workpiece could be thrown from the lathe
during operation, resulting in serious impact
injury or death.
Clamping Force. Inadequate clamping force
can lead to the workpiece being thrown
from the chuck and striking the operator
or bystanders. Maximum clamping force
is achieved when the chuck is properly
maintained and lubricated, all jaws are
fully engaged with the workpiece, and the
maximum chuck clamping diameter is not
exceeded.
Proper Maintenance.
maintained and lubricated to achieve
maximum clamping force and withstand
the rigors of centrifugal force. To reduce
the risk of a thrown workpiece, follow all
maintenance intervals and instructions in
this document.
Disconnect Power. Serious entanglement or
impact injuries could occur if the lathe is
started while you are adjusting, servicing, or
installing the chuck. Always disconnect the
lathe from power before performing these
procedures.
All chucks must be properly

Power Supply
Requirements
PREPARATION
The full-load current is not the maximum
amount of amps that the machine will draw. If
the machine is overloaded, it will draw additional
amps beyond the full-load rating.
Availability
Before installing the machine, consider the
availability and proximity of the required power
supply circuit. If an existing circuit does not meet
the requirements for this machine, a new circuit
must be installed.
To minimize the risk of electrocution, fire,

electrical wiring must be done by an electrician
or qualified service personnel in accordance with
all applicable codes.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power until
instructed later in this manual.
Full-Load Current Rating
The full-load current rating is the amperage
a machine draws at 100% of the rated output
power. On machines with multiple motors, this is
the amperage drawn by the largest motor or sum
of all motors and electrical devices that might
operate at one time during normal operations.
If the machine is overloaded for a sufficient
length of time, damage, overheating, or fire may
result—especially if connected to an undersized
circuit. To reduce the risk of these hazards,
avoid overloading the machine during operation
and make sure it is connected to a power supply
circuit that meets the requirements in the
following section.
Circuit Requirements
This machine is prewired to operate on a 220V
power supply circuit that has a verified ground

PREPARATION
This machine must be grounded! In the event
of certain types of malfunctions or breakdowns,
grounding provides a path of least resistance
for electric current in order to reduce the risk of
electric shock.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding
wire. If repair or replacement of the power cord
is necessary, do not connect the equipmentgrounding wire to a live (current carrying)
terminal.
Check with an electrician or qualified service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the machine is properly grounded.
If you ever notice that a cord is damaged or
worn, disconnect it from power, and immediately
replace it with a new one.
For Machines Mfg. Since 5/11
Extension CordsGrounding Requirements
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which may
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size get smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine
must contain a ground wire, match the required
plug and receptacle, and meet the following
requirements:
Minimum Gauge Size ...............................12 AWG
Maximum Length (Shorter is Better) ........... 50 ft.
The power cord and plug specified under Circuit

Cleaning & Protecting
For Machines Mfg. Since 5/11
The unpainted surfaces are coated at the factory
with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
The benefit of this rust preventative is that it
works very well. The downside is that it can be
time-consuming to thoroughly remove.
Be patient and do a careful job when cleaning
and removing the rust preventative. The time
you spend doing this will reward you with
smooth-sliding parts and a better appreciation
for the proper care of the unpainted surfaces.
lthough there are many ways to successfully
remove the rust preventative, the following
process works well in most situations.
Before cleaning, gather the following:
s $ISPOSABLErags
s #LEANERDEGREASER (certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
s 3AFETYGLASSESDISPOSABLEGLOVES

Before using these products, though, test them
on an inconspicuous area of a painted surface to
make sure they will not damage it.
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may
damage painted surfaces. Always follow the
manufacturer’s instructions when using any
type of cleaning product.
Basic steps for removing rust preventative:
1. Put on safety glasses and disposable gloves.
2. #OATALLSURFACESTHATHAVERUSTPREVENTATIVE
with a liberal amount of your cleaner or
degreaser and let them soak for a few
minutes.
3. Wipe off the surfaces. If your cleaner or

4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a
quality metal protectant or light oil to
prevent rust.

GAS
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used for
cleaning. Avoid using these
products to remove rust
preventative.
Many cleaning solvents are
toxic if inhaled. Minimize
your risk by only using
these products in a well
ventilated area.
Remove the end gear cover and end gears,
and use a stiff brush with mineral spirits
to clean the rust preventative from the
gears and shafts. DO NOT get any cleaner
or rust preventative on the V-belts, as it
could damage them or make them slip
during operations. If the belts do become
contaminated, replace them.

PREPARATION
LocationLocation
Physical Environment
The physical environment where your machine
is operated is important for safe operation and
longevity of parts. For best results, operate this
machine in a dry environment that is free from
excessive moisture, hazardous or flammable
chemicals, airborne abrasives, or extreme
conditions. Extreme conditions for this type
of machinery are generally those where the
ambient temperature is outside the range of 41°–
104°F; the relative humidity is outside the range
of 20–95% (non-condensing); or the environment
is subject to vibration, shocks, or bumps.
Electrical Installation
Place this machine near an existing power source
that meets the minimum circuit requirements.
Make sure all power cords are protected from
traffic, material handling, moisture, chemicals,
or other hazards. Leave access to disconnect the
power source or engage a lockout/tagout device.
Weight Load
Refer to the Machine Specifications for the
weight of your machine. Make sure that the
surface upon which the machine is placed will
bear the weight of the machine, additional
equipment that may be installed on the machine,
and the heaviest workpiece that will be used.
Additionally, consider the weight of the operator
and any dynamic loading that may occur when
operating the machine.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation
of auxiliary equipment. With permanent
installations, leave enough space around
the machine to open or remove doors/covers
as required by the maintenance and service
described in this manual.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed
safely. Shadows, glare, or strobe effects that
may distract or impede the operator must be

7. At each end of the lathe, have assistants
connect guide rods to safely keep the lathe
from swaying or tipping during lifting.
When lifting the lathe with straps, the load
will be top heavy. Take extra care to keep the
load balanced vertically and only lift the lathe
far enough to remove the shipping pallet.
8. Raise the lathe a couple of inches and check
the balance of the load.
— If the load is not safely balanced,
immediately lower the lathe and resolve
the issue before attempting to lift it
again.
For accurate turning results and to prevent
warping the cast iron bed and ways, the lathe
bedways MUST be leveled from side-to-side
and from front-to-back on both ends.
Re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
operation.
For best results, use a precision level that
is at least 12" long and sensitive enough to
show a distinct movement when a 0.003" shim
(approximately the thickness of one sheet of
standard newspaper) is placed under one end of
the level.
9. Raise the lathe enough to clear the shipping
pallet, carefully remove the pallet, then
lower the lathe into position.
See the figure below for an example of a high
precision level.
