IMPORTANT NOTICE!
Modification Required for Attaching Your Router
The universal phenolic mounting plate included with the Model T28048 DOES NOT feature pre-drilled
mounting holes due to the varying brands of routers using different mounting hole configurations.
To properly use this router table, holes will need to be drilled into the mounting plate that match the base
mounting hole configuration of your router. This procedure will require a drill press or hand-drill with
guide, the correct size drill bits, and possibly additional fasteners for mounting the router.
Before making any modifications to the phenolic mounting board, read the entire SETUP section in this
manual to make sure the person making the modification is capable of performing the required tasks,
and to make sure that your router is firmly secured to the router mounting board.

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 material. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing 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 modifications—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 during 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 recommended accessories. Using improper accessories 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 disconnecting 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 intended operation, stop using the machine! Contact our
Technical Support at (570) 546-9663.

Additional Safety for Router Tables
Serious cuts, amputation, entanglement, or death can occur from contact with rotating bit.
Bits or other parts improperly secured can fly off and strike nearby operators with great force.
Flying debris can cause eye injuries or blindness. To minimize risk of getting hurt or killed,
anyone operating shaper MUST completely heed hazards and warnings below.
AVOIDING AMPUTATION. To avoid making con-
tact with spinning router bit, never place hands
directly over or in front of bit. As one hand
approaches bit, move it away and over to other
side. Always keep hands at least 6" away from
spinning bit.
SECURING LEVERS AND KNOBS. Never operate router table without first making sure all lock
levers and knobs are tight, and all fence hardware
and guide rails are secure. Otherwise, workpiece
can slip out of alignment while cutting and cause
injury from kickback.
DO NOT FORCE WORKPIECE. Never force
materials past router. Let router bit do work.
Excessive force is likely to result in poor cutting
results and will cause kickback conditions that
could cause serious personal injury.
BLIND CUTTING. Keep router bit on underside
of workpiece when making blind cuts. This will
decrease risk of accidental contact with rotating
bit.
ROUTER BIT ROTATION. Always feed workpiece against rotation direction of bit. Otherwise,
workpiece could be aggressively pulled from your
hands, drawing them into spinning bit.
ROUTER BIT HEIGHT. Keep any unused portion
of bit below the table surface to minimize risk of
your hand contacting rotating bit.
APPROPRIATE WORKPIECES. Danger of kickback and injury is increased when workpiece
has knots, holes, or foreign objects in it. Warped
stock should be flattened with a jointer before you
shape it with router.
TESTING ROTATION. With router disconnected
from power, rotate router spindle to test any new
setup to ensure proper bit clearance before starting router.
CUTTING SUPPORT. NEVER cut workpiece
without using a fence, jig, or miter gauge as a
support guide. Otherwise, workpiece could be
aggressively pulled from your hands, drawing
them into spinning bit.
WORKPIECE SIZING. NEVER use workpiece
shorter than 6" without special fixtures or jigs.
Otherwise, workpiece can become trapped
between fence and router bit, which could draw
your hands into spinning bit.
USING SAFETY GUARDS. To prevent amputation or other injuries, always use a guard.
Fabricate additional guards or jigs for special
circumstances. Use an overhead guard if fence
is removed.
TRIPPING HAZARD. To prevent tripping over
power cord of router when not in use, always disconnect it and safely store it out of way.

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, consult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply 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.)

unsure about wiring practices or electrical
codes in your area.
Model T28048 (Mfd. Since 06/17)
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 a qualified electrician or 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.
We do not recommend using an extension cord
with this machine.
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:

The mounting plate included with the Model
T28048 is universal and designed to attach to the
bottom of your router in the same manner as the
base plate of the router. We recommend using the
base plate as a template for the hole pattern to be
drilled through the mounting plate.
IMPORTANT: When deciding how to orient the
router in relation to the router table, take into
account access to router controls, such as
variable speed dial, depth adjustments and other
locks or levers.
To attach router to mounting plate:
1. DISCONNECT MACHINE FROM POWER!
2. If necessary, remove fence assembly from
router table and table insert from mounting
plate (see Locking/Unlocking Table Inserts

Leveling
Connecting
Router Table
To reduce risk of injury from accidental
contact with spinning router bit, ALWAYS
make sure router table is placed on a flat,
clean surface and then leveled before router
operations.
The feet on the Model T28048 are adjustable and
used to level the router table. This keeps it from
rocking during routing operations.
To level router table:
1. Place router on a flat, clean surface.
2. Loosen (4) M10-1.5 hex nuts on router table
feet.
3. Lay a level across router table surface in pattern shown in Figure 30.
Power Cords
DO NOT connect router table power cords
to any power supply other than that listed in
Electrical section of this manual.
Electrocution, fire, shock,
may occur if machine is
and connected to power
supply.
Connection between router power cord and
switch power cord must be made outside
the dust-collection bag, where it is free of
dust and debris to reduce risk of fire.
4. Adjust router table feet to make sure level
lays flat on router table surface at positions
shown in Figure 30.

control. Two power cords are connected to the
switch. The shorter power cord has a 5-15 receptacle and connects to the router power cord. The
longer power cord has a 5-15 plug and connects
to a 110V power supply circuit.
To connect router and router table to power:
1. Make sure router table paddle switch is set to
OFF.
2. Feed router power cord through opening
at bottom of dust-collection bag, then close
opening.
3. Insert router power cord into 5-15 receptacle

Dust Collection
The Model T28048 has two dust ports. Both will
accept a 2
a standard (2
adapter.
This machine creates a lot of wood chips/
dust during operation. Breathing airborne
dust on a regular basis can result in permanent respiratory illness. Reduce your risk
by wearing a respirator and capturing the
dust with a dust collection system.
Recommended CFM at Dust Port: 100 CFM
Do not confuse this CFM recommendation with
the rating of the dust collector. To determine the
CFM at the dust port, you must consider these
variables: (1) CFM rating of the dust collector,
(2) hose type and length between the dust collector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines
throughout the system. Explaining how to calculate these variables is beyond the scope of
this manual. Consult an expert or purchase a
good dust collection "how-to" book.

Table T-Slot
When using a miter gauge, it is important to make
sure the fence boards are parallel to the table
T-slot. This will help ensure that the workpiece
does not bind or kickback during operation. Use a
fine ruler to make the distance equal between the
fence boards and the T-slot along the full length of
the table (see Figure 36).
To avoid workpiece kickback or binding
when using a miter gauge with this router
table, ALWAYS make sure fence boards are
parallel with table T-slot before beginning

Feeding small stock past the router bit increases
the risk of kickback from the workpiece slipping
into the space between the fence and bit. If you
must rout small stock, use a zero-clearance fence
board. This will provide greater protection for the
operator, better workpiece support, and reduced
tearout on narrow or fragile stock.
To make a zero-clearance fence:
1. DISCONNECT MACHINE FROM POWER!
2. Remove fence boards from fence assembly.
3. Select piece of straight and smooth stock that
is same height and thickness as fence boards
and approximately 24" long.
4. Cut outline of spindle and router bit from center of the stock selected in Step 3, as shown

ALWAYS use hold-downs or featherboards
and push sticks when shaping small or narrow stock. These devices keep your hands
away from spinning router bit and sufficiently support stock to allow a safe and effective
cut, reducing risk of personal injury.
6. Secure zero-clearance fence board and
router bit guard to fence assembly, then
make sure fence is parallel to the table T-slot
(see Squaring Fence & Table on Page 28).
Free-Hand Routing
Irregular or free-hand routing takes a high degree
of skill and dexterity and is done without the protection and aid of the fence assembly and router
bit guard. The most dangerous part of free-hand
routing is beginning the cut, when the router bit
first contacts the workpiece. It tends to jerk or kick
back, presenting an injury hazard to the operator.
Free-hand or irregular routing greatly
increases the chance that the operator may
lose control of the workpiece, which could
result in serious personal injury. Therefore,
a starting pin or block and a custom guard
or workpiece holding jig MUST be used.
To reduce the likelihood of kickback when freehand routing, use the starting pin or block (see
Figures 46 & 47 for examples). This will allow
you to anchor and slowly pivot the workpiece into
the bit as the cut is started, making the operation
more stable and safe.
7. Check for proper clearance, connect router to
power, then make test cut to verify results.

3. Remove fence assembly from table.
ALWAYS use an auxiliary jig and extreme
care when free-hand routing. Routing
without fence and attached guard greatly increases risk of accidental contact

personal injury.
To free-hand rout:
1. DISCONNECT MACHINE FROM POWER!
2. Fabricate a jig to use with workpiece that
matches desired finished shape, then attach
it to workpiece (see Figure 47).
Note: Make sure any fasteners used will not
make contact with the router bit during routing operation. Hot glue can be used as an
alternative.
4. If possible, fabricate and mount a custom
guard over the bit that safely protects your
hands from spinning router bit.

follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Check:
• Loose router mounting fasteners.
• Loose mounting plate fasteners.
• Loose frame and table fasteners.
• Worn switch.
• Worn or damaged cords and plugs.
• Any other condition that could hamper the
safe operation of this router table.
Always disconnect power
to the router before performing maintenance.
Failure to do this may
result in serious personal injur y.
Cleaning &
Protecting
Frequently vacuum sawdust and wood chips from
the table and router, then blow off the remaining dust with compressed air. This is especially
important for the internal working parts of the
fence assembly and the router. Dust build-up
around the router is a sure way to decrease its
life span.

Wiring Safety Instructions
SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical components!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
This includes the installation of unapproved aftermarket parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires disconnected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious personal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
