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 spinning bit.
Improperly secured bits or spindle parts/fasteners can fly off and strike nearby operators
or bystanders with great force. Flying dust or debris from cutting operation can cause eye
injuries or blindness. To minimize risk of getting hurt or killed, anyone operating router 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.
TESTI NG ROTAT I ON. 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.
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 may result in serious personal injury or property damage.

The Model T1244 mounts on most table saws
that have 27" deep tables. If your table saw does
not have mounting holes for the installation of
the router table, you will need to drill and tap
these holes in the saw table. Also, you may have
to modify the fence rails to allow access for the
router table T-slots, and drill the fence rails to align
with the extension wing mounting holes.
Read this entire assembly section before beginning the installation procedure below to make
sure the T1244 will fit your table saw.

The universal aluminum router mounting plate
included with the T1244 is designed to attach to
the bottom of your router in the same manner as
the router base. When installed, the weight of the
router holds the mounting plate in place.
We recommend using the router base as a
template for the hole pattern to be drilled in the
mounting plate. The router mounting plate has 15
pre-marked pilot holes to assist in attaching it to
the router.
IMPORTANT: When deciding how to orient the
router in relation to the router wing table, consider
access to all router controls, adjustment knobs,
lock levers, and the power switch.
To attach router to router mounting plate:
DISCONNECT ROUTER FROM POWER!
1.
2. Mark front of mounting plate with tape or
erasable marker.
Lift mounting plate out of table opening, and
3.
lay it bottom-side-up on a protected working
surface to prevent scratching top surface of
mounting plate.

The Model T1244 has one 21⁄2 " dust port and an
1
adapter to fit a 2
⁄4" diameter shop vacuum hose.
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.

IMPORTANT: The operator is very careful to
keep the workpiece firmly against the table
and fence and hands away from the rotating
router bit during the entire cut.
• Wet or "Green" Stock: Cutting wood with a
moisture content over 20% causes unnecessary wear on the blades, increases the risk of
kickback, and yields poor results.
• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and
often unpredictable when being cut. DO NOT
cut workpieces with these characteristics!

8.
Workpiece
Inspection
Some workpieces are not safe to cut or may
require modification before they are safe to cut.
Before cutting, inspect all workpieces for the
following:
• Material Type: This machine is intended for
cutting natural and man-made wood products, laminate-covered wood products, and
some plastics. Cutting drywall or cementitious backer board creates extremely fine
dust and may reduce the life of the bearings.
This machine is NOT designed to cut metal,
glass, stone, tile, etc.; cutting these materials
with a table saw may lead to injury.
• Foreign Objects: Nails, staples, dirt, rocks
and other foreign objects are often embedded in wood. While cutting, these objects
can become dislodged and hit the operator,
cause kickback, or break the blade, which
might then fly apart. Always visually inspect
your workpiece for these items. If they can't
be removed, DO NOT cut the workpiece.
• Large/Loose Knots: Loose knots can
become dislodged during the cutting operation. Large knots can cause kickback and
machine damage. Choose workpieces that
do not have large/loose knots or plan ahead
to avoid cutting through them.
• Minor Warping: Workpieces with slight cupping can be safely supported if the cupped
side is facing the table or the fence. On
the contrary, a workpiece supported on the
bowed side will rock during a cut and could
cause kickback or severe injury.
Adjusting Bit Guard
A transparent bit guard is included with the Model
T1244 to minimize operator exposure to the spinning router bit. The guard secures to the fence
with (2) 3-lobe knobs, (2) fender washers, and (2)
T-bol ts.
The bit guard adjusts up and down and side to
side to accommodate various router bits (see
Figure 29). For your own safety, the bit guard
must be positioned vertically not more than
above the workpiece, and centered horizontally on
the gap between the infeed and outfeed fences.

Adjusting FencesTable Inserts
The fence assembly on the Model T1244 has an
infeed fence and an outfeed fence. Each fence
can be moved toward or away from bit up to 2".
The entire fence assembly can be moved forward
and backward up to 4
IMPORTANT: Fences should be adjusted as
close to the bit as possible without touching in
order to minimize risk of injury and produce best
results.
To adjust the fences, loosen the four fence adjustment knobs (see Figure 30) and the two knobs on
the bit guard (see Figure 29 on Page 19). Tighten
all knobs when complete.

Squaring Fence &
Table
When using a miter gauge, the fence assembly
must be parallel to the table T-slot for safe and
accurate cutting results. Use a fine ruler to make
the distance equal between the fence assembly
and the T-slot along the full length of the table
(see Figure 34).
Kickback injury may occur if fence is not
parallel with T-slot. When using a miter
gauge with this router table, ALWAYS
make sure fence assembly is parallel with
table T-slot BEFORE beginning routing
operations.
Edge Jointing
Jointing the edge of a board involves using a
straight cutting router bit to remove wood from the
face of the board. The result is a perfectly flat and
square edge.
Always feed workpiece against router bit
rotation direction, as illustrated below.
Otherwise, workpiece could be aggressively pulled from your hands, drawing them
into spinning cutter.

Routing Small Stock
Feeding small stock past the router bit is always
dangerous. If you must route small stock, use a
zero-clearance fence. This will provide greater
protection for the operator, better workpiece support, and reduced tear out on narrow or fragile
stock.

6.
bly, check for proper clearance, connect

cutter to verify results.
ALWAYS use hold-downs or featherboards
and push sticks when shaping small or narrow stock. These devices keep your hands
away from spinning cutter and sufficiently
support stock to allow a safe and effective
cut, reducing risk of personal injury.
Free-Hand Routing
To make a zero-clearance fence:

2. Remove infeed and outfeed fences from
fence assembly.
Select a piece of straight and smooth stock

in Figure 40.
Note: Make the outline as close as possible
to the cutter and spindle without interfering
with rotation.
Mounting Fastener
Zero-Clearance Fence
Irregular or free-hand routing, as illustrated in
Figure 41 (next page), takes a high degree of
skill and dexterity and is done without the protection and aid from the fence and router bit guard.
The most dangerous part of free-hand routing is
beginning the cut, when the cutter first contacts
the workpiece. Often the workpiece will tend to
jerk or kickback, presenting an injury hazard to
the operator.
Free-hand or irregular
routing greatly increases
chance that operator may
lose control of 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 a starting pin or block (see
Figures 41–42). This will allow you to anchor and
slowly pivot the workpiece into the cutter as the
cut is started, making the operation more stable
and safe.
To free-hand route:
DISCONNECT ROUTER FROM POWER!

then wipe away the remaining dust with a clean
shop rag. 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.
For optimum performance from this accessory, this maintenance schedule must be strictly
followed.
Ongoing
To maintain a low risk of injury and proper
accessory operation, if you ever observe any of
the items below, stop using the accessory immediately and fix the problem before continuing
operations:
• Loose mounting bolts.
• Damaged router bit.
Worn or damaged wires.
•
Any other unsafe condition that could hamper
•
the safe operation of the router table wing
extension.
Weekly Maintenance
• Clean/vacuum dust buildup from router and
T-slots on table wing extension and infeed
and outfeed boards.
The cast-iron router table can be kept rust-free
with regular applications of products like SLIPIT®
(see Figure 44).
