Model SB1494 SAFETY
Understanding Risks of Machinery
Operating all machinery and machining equipment can be dangerous or relatively safe depending
on how it is installed and maintained, and the operator's experience, common sense, risk awareness,
working conditions, and use of personal protective equipment (safety glasses, respirators, etc.).
The owner of this machinery or equipment is ultimately responsible for its safe use. This
responsibility includes proper installation in a safe environment, personnel training and usage
authorization, regular inspection and maintenance, manual availability and comprehension,
application of safety devices, integrity of cutting tools or accessories, and the usage of approved
personal protective equipment by all operators and bystanders.
The manufacturer of this machinery or equipment will not be held liable for injury or property
damage from negligence, improper training, machine modifications, or misuse. Failure to read,
understand, and follow the manual and safety labels may result in serious personal injury, including
amputation, broken bones, electrocution, or death.
The signals used in this manual to identify hazard levels are as follows:
Death or catastrophic
harm WILL occur.
Moderate injury or fire
MAY occur.
Death or catastrophic
harm COULD occur.
Machine or property
damage may occur.
Basic Machine Safety
Owner’s Manual: All machinery and machining
equipment presents serious injury hazards
to untrained users. To reduce the risk of
injury, anyone who uses THIS item MUST
read and understand this entire manual
before starting.
Personal Protective Equipment: Operating or
servicing this item may expose the user

SAFETY
Entanglement: Loose clothing, gloves, neckties,
jewelry or long hair may get caught in
moving parts, causing entanglement,
amputation, crushing, or strangulation.
Reduce this risk by removing/securing
these items so they cannot contact moving
parts.
Mental Alertness: Operating this item with
reduced mental alertness increases the
risk of accidental injury. Do not let a
temporary influence or distraction lead to a
permanent disability! Never operate when
under the influence of drugs/alcohol, when
tired, or otherwise distracted.
Safe Environment: Operating electrically
powered equipment in a wet environment
may result in electrocution; operating near
highly flammable materials may result in a
fire or explosion. Only operate this item in
a dry location that is free from flammable
materials.
Electrical Connection: With electically powered
equipment, improper connections to the
power source may result in electrocution
or fire. Always adhere to all electrical
requirements and applicable codes when
connecting to the power source. Have all
work inspected by a qualified electrician to
minimize risk.
Disconnect Power: Adjusting or servicing
electrically powered equipment while it
is connected to the power source greatly
increases the risk of injury from accidental
startup. Always disconnect power
BEFORE any service or adjustments,
including changing blades or other tooling.
Secure Workpiece/Tooling: Loose workpieces,
cutting tools, or rotating spindles can
become dangerous projectiles if not
secured or if they hit another object during
operation. Reduce the risk of this hazard
by verifying that all fastening devices are
properly secured and items attached to
spindles have enough clearance to safely
rotate.
Chuck Keys or Adjusting Tools: Tools used to
adjust spindles, chucks, or any moving/
rotating parts will become dangerous
projectiles if left in place when the machine
is started. Reduce this risk by developing
the habit of always removing these tools
immediately after using them.
Work Area: Clutter and dark shadows increase
the risks of accidental injury. Only operate
this item in a clean, non-glaring, and well-
lighted work area.
Properly Functioning Equipment: Poorly
maintained, damaged, or malfunctioning
equipment has higher risks of causing
serious personal injury compared to
those that are properly maintained.
To reduce this risk, always maintain
this item to the highest standards and
promptly repair/service a damaged or
malfunctioning component. Always follow
the maintenance instructions included in
this documentation.
Unattended Operation: Electrically powered
equipment that is left unattended while
running cannot be controlled and is
dangerous to bystanders. Always turn the
power OFF before walking away.
Health Hazards: Certain cutting fluids and
lubricants, or dust/smoke created when
cutting, may contain chemicals known to
the State of California to cause cancer,
respiratory problems, birth defects,
or other reproductive harm. Minimize
exposure to these chemicals by wearing
approved personal protective equipment
and operating in a well ventilated area.
Difficult Operations: Attempting difficult
operations with which you are unfamiliar
increases the risk of injury. If you
experience difficulties performing the
intended operation, STOP! Seek an
alternative method to accomplish the
same task, ask a qualified expert how the
operation should be performed, or contact
our Technical Support for assistance.

South Bend Tools
Model SB1494 SAFETY
Additional Safety for Grinders
Spark Deflector Gap. Keep gap between end of
spark deflector and grinding wheel between
1⁄8"and 1⁄4". If gap is larger, pinch hazard
increases and excessive sparks/abrasives can
be expelled toward operator.
Wheel Attachment. Only use flanges included
with grinder when mounting wheels. Other
flanges may not properly secure wheel and
cause an accident. Do not use warped or
damaged flanges and always use paper discs
(blotters) between wheels and flanges to
reduce risk of flanges cracking wheel when
tightened. Only tighten wheel spindle nut
enough to drive wheel and prevent slippage.
Eye Shields. Place eye shields close to grinding
wheel and re-adjust as wheel wears down.
Tool Rest Position. If tool rest is too far away
from wheel, it forms an “in-running nip
point"gap which may cause workpiece to be
pulled down, leading to loss of control and
pulling your hand into grinding wheel. Keep
tool rest within 1⁄8"of wheel when operating
to minimize risk of pinching and crushing
injuries. Replace grinding wheel when tool
rest gap is wider than 1⁄8", and when no
additional adjustment can be made.
Handle & Wheel Contact. Keep a firm grip on
workpiece and position your hands a safe
distance away when grinding. Anticipate
when workpiece will heat up, and cool it
before it becomes too hot to hold, or use
appropriate clamp. Avoid wearing gloves as
they may get caught in grinding wheel and
cause more serious entanglement injuries.
Safe Mounting & Work Area. An unsecured
grinder may become dangerously out of
control during operation. Before use, verify
grinder is FIRMLY secured in location
free of explosive or flammable materials.
Frequently clean grinding dust from beneath
grinder and inside wheel cover.
Starting Grinder. If wheel is damaged, it will
usually fly apart shortly after start-up. To
protect yourself, always stand to side of
grinder when turning it ON and allow it to
run for at least one minute before standing
in front of it. Never grind with wheel that
vibrates.
Wheel Inspection. Verify grinding wheels are free
of cracks, chips, or dents in wheel surface
before installing. Do not use wheel if it has
any of these problems or it could break apart
during operation. Replace wheel or shaft
bearings immediately. Perform a “ring test”
on grinding wheels before installation to
ensure they are safe to use. A wheel that
does NOT pass ring test may break or fly
apart during operation.
Wheel Speed Rating. Wheels operated at a faster
speed than rated for may break apart during
operation. Before mounting new wheel, be
sure wheel RPM rating is equal to or higher
than speed of grinder. Never use unmarked
wheels or wheel rated for lower speed than
grinder.
Avoiding Entanglement. Becoming entangled
in moving parts can cause severe injury or
death. Keep all guards and covers in place;
DO NOT wear loose clothing, gloves, or
jewelry; and tie back long hair.
Eye, Face, & Lung Protection. Grinding ejects
small particles at high rate of speed. These
particles can cause blindness, skin injuries,
or respiratory damage. ALWAYS wear
approved clothing, safety goggles, face
shield, and respirator for type of grinding.
Side & Top Grinding. Grinding on side of wheels
can cause them to crack and burst—unless
wheel is rated for side grinding. Grinding
on top of wheels greatly increases risk
of workpiece kickback. Always grind on
downward part of wheel.
Serious injury or death can occur from impact injuries if grinding wheel breaks apart during use.
Entanglement/amputation injuries can occur from being caught in moving parts or in-running
pinch points. Flying sparks can ignite explosive or flammable materials. Rotating grinding wheels
can easily remove skin. To minimize risk of getting hurt or killed, anyone operating machine MUST
completely heed hazards and warnings below.

Power Supply
Requirements
Electrocution or fire may
occur if machine is not
correctly grounded and
attached to the power
supply. Use a qualified
electrician to ensure a safe
power connection.
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,
or equipment damage, installation work and
electrical wiring must be done by a
n electrician
or qualified service personnel
in accordance with
applicable electrical codes and safety standards.
Availability
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.
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.
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.
Full-Load Current Rating
Full-Load Rating at 110V..................... 7 Amps
For your own safety and protection of property,
consult an electrician if you are unsure about
wiring practices or applicable electrical codes.
Note: The circuit requirements in this manual
are for
a dedicated circuit—where only one
machine will be running at a time. If this
machine will be connected to a shared circuit
where multiple machines will be running at
the same time, consult a qualified electrician to
ensure the circuit is properly sized.
A power supply circuit includes all electrical
equipment between the main breaker box or fuse
panel in your building and the incoming power
connections inside the machine. This circuit
must be safely sized to handle the full-load
current that may be drawn from the machine for
an extended period of time. (If this machine is
connected to a circuit protected by fuses, use a
time delay fuse marked D.)

PREPARATION
Grounding Requirements
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.
Grounding Prong
Current Carrying Prongs
5-15 PLUG

5-15 RECEPTACLE
Figure 4. NEMA 5-15 plug and receptacle.
DO NOT modify the
included plug or use an
adapter if it will not fit your
receptacle. Instead, have a
qualified electrician install
the proper receptacle on a
power supply circuit that
is grounded and meets
the requirements for this
machine.
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 or
plug is necessary, do not connect the equipment-
grounding 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 tool is properly grounded.
If you ever notice that a cord or plug is
damaged or worn, disconnect it from power, and
immediately replace it with a new one.
Extension Cords
Minimum Gauge Size............................14 AWG
Maximum Length (Shorter is Better) ....50 ft.
We do not recommend using an extension cord
with this machine. If you must use one, 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 gets 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 listed in the
Circuit
Requirements
for the applicable voltage, and
meet the following requirements:
For 110V operation: This machine is equipped
with a
power cord that has an equipment-
grounding
wire and a grounding plug (similar
to
the figure below). The plug must only be
inserted
into a matching receptacle (outlet) that
is properly installed and grounded in accordance
with all local codes and ordinances.
For 220V operation: Use the plug type listed in
the
Circuit Requirements
for this voltage. The
listed plug (similar to the following figure) has
an equipment-grounding wire to safely ground
the machine.

PREPARATION
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.
Although there are many ways to successfully
remove the rust preventative, the
following
process works well in most situations
.
Before cleaning, gather the following:
• Disposable
rags
• Cleaner/degreaser
(certain citrus-based
degreasers work extremely well and they
have non-toxic fumes)
• Safety glasses & disposable gloves
Note:
Automotive degreasers, mineral spirits, or
WD•40 can be used to remove rust preventative.
Before using these products, though, test them
on an inconspicuous area of a painted surface to
make sure they will not damage it.
Basic steps for removing rust preventative:
1. Put on safety glasses and disposable gloves.
2. Coat all surfaces that have rust preventative
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
degreaser is effective, the rust preventative
will wipe off easily.
Note: To clean off thick coats of rust
preventative on flat surfaces, such as beds
or tables, use a PLASTIC paint scraper to
scrape off the majority of the coating before
wiping it off with your rag. (Do not use a
metal scraper or it may scratch the surface.)
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.
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.

A great product for removing the waxy shipping
grease from the non-painted parts of the
machine during clean up.

Bench Mounting
The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.
The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.
Figure 10. "Through Mount" setup.

Another option is a "direct mount" (see example
below) where the machine is secured directly to
the workbench with lag screws and washers.

Location
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.
Children or untrained
people may be seriously
injured by this machine.
Only install in an access
restricted location.

PREPARATION
Assembly
The machine must be fully assembled before it
can be operated. Before beginning the assembly
process, refer to Required for Setup on Page
9and gather all listed items. To ensure the
assembly process goes smoothly, first clean any
parts that are covered or coated in heavy-duty
rust preventative (if applicable).
To assemble machine:
1. Attach (1) work rest support to right wheel
guard with (1) 5⁄16"-18 x 3⁄4" handle, 5⁄16" lock
washer, 5⁄16" flat washer, and 1⁄4"-20 x 3⁄8" cap
screw (see Figure 12).

PREPARATION
Power Connection
Electrocution or fire
may occur if machine is
ungrounded, incorrectly
connected to power, or
connected to an undersized
circuit. Use a qualified
electrician to ensure a safe
power connection.
Once your machine is set up and assembled as
previously described in this manual, it is ready to
be connected to the power source.
Note About Extension Cords: Using an
incorrectly sized extension cord may decrease the
life of electrical components on your machine.
