Model SB1124F 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
to flying debris, dust, smoke, dangerous
chemicals, or loud noises. These hazards
can result in eye injury, blindness, long-
term respiratory damage, poisoning,
cancer, reproductive harm or hearing loss.
Reduce your risks from these hazards
by wearing approved eye protection,
respirator, gloves, or hearing protection.
Trained/Supervised Operators Only: Untrained
users can seriously injure themselves
or bystanders. Only allow trained and
properly supervised personnel to operate
this item. Make sure safe operation
instructions are clearly understood. If
electrically powered, use padlocks and
master switches, and remove start switch
keys to prevent unauthorized use or
accidental starting.
Guards/Covers: Accidental contact with
moving parts during operation may cause
severe entanglement, impact, cutting,
or crushing injuries. Reduce this risk by
keeping any included guards/covers/doors
installed, fully functional, and positioned
for maximum protection.

South Bend Tools
For Machines Mfd. Since 11/22 Model SB1124F
-11-
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 electrically
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.

Model SB1124F SAFETY
Additional Milling Machine Safety
Understanding Controls:
Make sure you
understand the function and proper use of all
controls before starting. This will help you
avoid making mistakes that result in serious
injury.
Avoiding Entanglement:
DO NOT wear loose
clothing, gloves, or jewelry, and tie back long
hair. Keep all guards in place and secure.
Always allow spindle to stop on its own. DO
NOT stop spindle using your hand or any
other object.
Wear Face Shield:
Always wear a face shield
in addition to safety glasses. This provides
more complete protection for your face than
safety glasses alone.
Use Correct Spindle Speed:
Follow
recommended speeds and feeds for each size
and type of cutting tool. This helps avoid tool
breakage during operation and ensures best
cutting results.
Inspect Cutting Tool:
Inspect cutting tools for
sharpness, chips, or cracks before each use.
Replace dull, chipped, or cracked cutting
tools immediately.
Properly Secure Cutter:
Firmly secure cutting
tool or drill bit so it does not fly out of
spindle during operation.
Power Disruption:
In the event of a local power
outage during operation, turn machine OFF
to avoid a possible sudden startup once
power is restored.
Clean Machine Safely: Metal chips or shavings
can be razor sharp. DO NOT clear chips
by hand or compressed air that can force
chips farther into machine—use a brush or
vacuum instead. Never clear chips while
spindle is turning.
Secure Workpiece To Table: Clamp workpiece
to table or secure in a vise mounted to
table, so workpiece cannot unexpectedly
shift or spin during operation. NEVER hold
workpiece by hand during operation.
Properly Maintain Machine: Keep machine
in proper working condition to help ensure
that it functions safely and all guards and
other components work as intended. Perform
routine inspections and all necessary
maintenance. Never operate machine with
damaged or worn parts that can break or
result in unexpected movement during
operation.
Disconnect Power First: To reduce risk of
electrocution or injury from unexpected
startup, make sure mill/drill is turned
OFF, disconnected from power, and that all
moving parts have come to a complete stop
before changing cutting tools or starting
any inspection, adjustment, or maintenance
procedure.
Remove Chuck Key & Spindle Tools: Always
remove chuck key, drawbar wrench, and
other tools used on the spindle immediately
after use. This will prevent them from being
thrown by the spindle upon startup.
You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating
cutter/spindle. You can be severely cut or have fingers amputated from contact with rotating cutters.
You can be blinded or struck by broken cutting tools, metal chips, workpieces, or adjustment tools
thrown from the rotating spindle with great force. To reduce your risk of serious injury when operating
this machine, completely heed and understand the following:

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
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.
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 220V.................. 9.6 Amps
Full-Load Rating at 440V.................. 4.8 Amps
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.
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.

PLUG
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.
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 440V operation: As specified in Circuit
Requirements
for 440V, the machine must be
hardwired to the power source, using a locking
switch as a disconnecting means (see below). The
machine must also be connected to a grounded
metal permanent wiring system; or to a system
having an equipment-grounding conductor. Due
to the complexity and high voltage involved, this
type of installation MUST be done by a qualified
electrician.
No adapter should be used with plug. If
plug does not fit available receptacle, or if
machine must be reconnected for use on a
different type of circuit, reconnection must
be performed by an electrician or qualified
service personnel, and it must comply with all
local codes and ordinances.

Converting Voltage
to 440V
The Model SB1124F is prewired to run on 220V
power, but it can be converted to 440V operation.
This conversion consists of: 1) Disconnecting the
machine from power, 2) rewiring the transformer
for 440V operation, 3) replacing the overload
relay, and 4) rewiring the motors for 440V
operation.
All wiring changes must be inspected by a
qualified electrician or service personnel before
the saw is connected to the power source. If,
at any time during this procedure you need
assistance, call Grizzly Tech Support at (570)
546-9663.
Phase Converters
DO NOT use a static phase converter to create
3-phase power—it can quickly decrease the
life of electrical components on this machine.
If you must use a phase converter, only use a
rotary phase converter. See the Model G5844 in
Accessories on Page 47.
Extension Cords (220V Only)
Minimum Gauge Size............................12 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:
To convert SB1124F to 440V operation:
1. DISCONNECT MACHINE FROM POWER!
2. Open electrical cabinet and locate
transformer (see Figure 9).
3. Move "R" wire from 220V terminal to 440V

Model SB1124F 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.
