SECTION 1: SAFETY
ELECTRICAL EQUIPMENT INJURY RISKS.
You can be shocked, burned, or killed by touching
live electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.
Always discon-
nect machine from power supply BEFORE mak-
ing adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unin-
tended startup or contact with live electrical com-
ponents.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained oper-
ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis-
connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin-
ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

NOTICE
Safety Instructions for Machinery
SECTION 1: SAFETY

-8- Model G4179 (Mfd. Since 01/22)
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica-
tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement dur-
ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec-
ommended accessories. Using improper acces-
sories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!
MAINTAIN POWER CORDS. When disconnect-
ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend-
ed operation, stop using the machine! Contact our
Technical Support at [phone].

Model G4179 (Mfd. Since 01/22) -9-
Additional Safety for Power Feeders
Serious injury or death can occur from getting hands, clothing, or jewelry entangled in moving
parts of power feeder or being pulled into cutting tool on attached machinery. Workpieces
ejected by attached machine can strike operator or bystanders with significant force, causing
impact injuries. To minimize risk of injury, anyone operating this machine MUST completely
heed hazards and warnings below.
FEATHERBOARD. When cutting long or large
stock that is difficult to feed properly, use a feath-
erboard with power feeder (on the infeed side) to
maintain even pressure and control of workpiece
against fence, and to help reduce risk of kickback.
FEED WORKPIECE PROPERLY. To reduce risk
of kickback, verify blade or cutter of associated
machine is at full speed before feeding stock
with power feeder. Avoid feeding workpiece too
quickly. Always verify power feeder wheels are
slightly lower than workpiece to ensure it will not
slip during cutting operation. Stop power feeder
BEFORE stopping cutting tool.
WORKPIECE SUPPORT. Loss of workpiece con-
trol while feeding can increase risk of kickback.
Support workpiece continuously during opera-
tion as required. Use auxiliary stands or support
tables for long or wide stock.
ADJUSTMENTS/MAINTENANCE. Make sure
power feeder and associated machine are turned
OFF, disconnected from power, and all moving
parts are completely stopped before doing adjust-
ments or maintenance.
ATTACHED MACHINERY. Follow all warnings
and safety information for attached machine doing
cutting work.
HAND SAFETY. To reduce risk of accidental
entanglement/pinch injuries between power feed-
er rollers and workpiece, or contact with blade/cut-
ter of associated machine, keep hands away from
rotating parts of power feeder. Turn power feeder
and associated machine OFF before removing
chips, sawdust, or cutoffs—DO NOT use your
hands.
INSTALLING GUARDS. To reduce risk of kick-
back and accidental contact with blade/cutter
of associated machine, always install guards,
fences, and hold-downs before starting attached
machine and power feeder. Repair or replace
guards promptly if they become damaged.
KICKBACK. Occurs when workpiece is ejected
from machine at a high rate of speed. To reduce
risk of kickback-related injuries (blindness, broken
bones, bruises, amputation, severe lacerations,
and death), use quality workpieces and proper
setup or maintenance of power feeder or associ-
ated machine. Never stand in path of workpiece.
VERIFY EACH SETUP. An improperly adjusted
power feeder can increase risk of kickback,
because it will continue feeding even if stock is
not properly positioned for cut. Ensure that power
feeder is set up correctly and firmly secured
before feeding workpiece.
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, serious
personal injury may occur.

-10- Model G4179 (Mfd. Since 01/22)
SECTION 2: POWER SUPPLY
Availability
Before installing the machine, consider the avail-
ability 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 an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
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.
Full-Load Current Rating at 220V ....... 4 Amps
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 over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
Circuit Requirements for 220V
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage ......... 208V, 220V, 230V, 240V
Cycle ..........................................................60 Hz
Phase ........................................... Single-Phase
Power Supply Circuit ......................... 15 Amps
Plug/Receptacle ............................. NEMA 6-15
Cord ........“S”-Type, 3-Wire, 14AWG, 300 VAC
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to
safely handle the full-load current 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.)

Model G4179 (Mfd. Since 01/22) -11-
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 nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel 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, discon-
nect it from power, and immediately replace it with
a new one.
Extension Cords
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 can
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
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size ...........................16 AWG
Maximum Length (Shorter is Better).......50 ft.
Figure 3. Typical 6-15 plug and receptacle.
Grounding Pin
Current Carrying Prongs
6-15 PLUG
GROUNDED
6-15 RECEPTACLE
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.
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
Grounding Instructions
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
The power cord and plug specified under “Circuit
Requirements for 220V”
on the previous page
has an equipment-grounding wire and a ground-
ing prong. 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 (see figure below).

Cleanup
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
There are many ways to remove this rust preven-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac-
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
• Disposable rags
• Cleaner/degreaser (WD•40 works well)
• Safety glasses & disposable gloves
• Plastic paint scraper (optional)
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2. Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
NOTICE
Avoid harsh solvents like acetone or brake
parts cleaner that may damage painted sur-
faces. Always test on a small, inconspicu-
ous location first.
Children and visitors may be
seriously injured if unsuper-
vised around this machine.
Lock entrances to the shop
or disable start switch or
power connection to prevent
unsupervised use.
Site Considerations
Workbench Load
Refer to the Machine Data Sheet for the weight
and footprint specifications of your machine.
Some workbenches may require additional rein-
forcement to support the weight of the machine
and workpiece materials.
Consider anticipated workpiece sizes and addi-
tional space needed for auxiliary stands, work
tables, or other machinery when establishing a
location for this machine in the shop. Below is
the minimum amount of space needed for the
machine.

Assembly
You MUST assemble all guards, fences, and
hold-downs before starting your machine or
power feeder. Failure to heed this warning
could result in serious personal injury.

Figure 8. Assembled unit.
The machine must be fully assembled before it
can be operated. Before beginning the assembly
process, refer to
Needed for Setup
and gather
all
listed items.
To ensure the assembly process
goes smoothly, first clean any
parts that are
cov-
ered or coated in heavy-duty rust preventative (if
applicable).
Tip: We recommend using a set of C-clamps to
temporarily secure the base while assembling the
power feeder to prevent it from tipping. You will
mount the power feeder to the machine table after
completing the assembly process. Refer to Base
Mounting on Page 17 for specific details.
To correctly position this power feeder on your
table top, completely assemble the power feeder
first in the order of A, B and C as shown in
Figures 7–8. Next, refer to Base Mounting on
Page 17. With the power feeder unit completely
assembled, it will be easier to locate where on the
table top you will need to drill your base mounting
holes, so you can take advantage of the full range
of power feeder swing and adjustments.

Power Connection
Before the machine can be connected to the
power source, an electrical circuit and connec-
tion device must be prepared per the POWER
SUPPLY section in this manual, and all previ-
ous setup instructions in this manual must be
complete to ensure that the machine has been
assembled and installed properly.
Always make sure the power switch on the
machine is turned OFF (or the OFF button is
pushed in) before connecting power.
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
Connecting Plug to Power Cord
To connect plug to power cord, install 6-15 plug
on end of power cord per plug manufacturer's
instructions. If no instructions were included, use
wiring diagram on Page 33.
Note About Extension Cords: Using an incor-
rectly-sized extension cord may decrease the life
of electrical components on your machine. If you
must use an extension cord, refer to Extension
Cords on Page 11 for more information.

Position the power feeder on the table top to
determine where to drill the base mounting holes
in order to maximize power feeder swing and
adjustment options.
Use the included base-bolt pattern template to
align the mounting holes. Consider the available
mounting choices for your needs: Through-Bolt
Mounting and Direct Mounting (discussed on
Page 18).
With either mounting choice, leave room to oper-
ate the hand cranks and lock levers to position the
rubber rollers parallel with the table surface and
approximately 1⁄8" lower than the thickness of the
workpiece.
Also, aim the front of the power feeder slight-
ly towards the machine fence (see Figure 9)
with approximately 1° to 1.5° toe-in toward the
machine fence, so the rubber rollers lightly push
the workpiece against the fence during cutting
operations.
If cutting long or large stock that is difficult to feed
properly, use a featherboard before the power
feeder (on the infeed side) to maintain even pres-
sure and control of the workpiece against the
fence.

To correctly position this power feeder on your
table top, completely assemble the power feeder
first, then refer to this section and mount your
base to the table using one of the two methods
below. The reason for this order is that with the
power feeder unit completely assembled, it will
be easier to locate where on the table top you will
need to drill your base mounting holes, so you can
take advantage of the full range of power feeder
swing and adjustments.
Through-Bolt Mounting
We recommend that you mount your new power
feeder to the machine table with through bolts,
nuts, and washers (see Figure 10). This option
will give the most rigidity and clamping strength to
prevent the feeder base from twisting out of align-
ment during use. However, if under-table support
webs interfere with washer or nut locations under
the table, you must use an optional clamping kit,
or drill and thread holes directly into the table as
described in Direct Mounting.
Direct Mounting
Use the included mounting template to drill and
tap your table, so the power feeder base can
be directly mounted to the table surface (see
Figure 11). If the table is thinner than 3⁄8" thick
where the threaded holes would be drilled and
tapped, or if support webbing is in the way, the
threads may strip or loosen as the power feeder is
used. Thread locking compound will not cure this
situation. Revert to the Through-Bolt Mounting
option. In any case, make sure to use a medium-
grade liquid thread locking compound on all
threads.
