Safety Instructions for Machinery
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, disconnect 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 machinery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
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.
nect machine from power supply BEFORE making adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unintended startup or contact with live electrical components.
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.
Always discon-
Model T31637/T31638 (Mfd. Since 01/20)
-7-
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 the 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 spinning
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 spinning bit.
ROUTER BIT SPEED. Do not exceed recommended speed of any router bit. Doing so can
cause bit to fracture or explode and cause injury.
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.
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 N G ROTATIO N. With router disconnected
from power, rotate router spindle to test any new
setup to ensure proper bit clearance before starting router.

INSTALLING ROUTER BIT. Insert at least
bit shank into collet, and allow
between shank and bottom of collet to ensure bit
is securely installed.

Installing Router
Tools Needed: Qty
Hex Wrench 5mm .............................................. 1
The Model T31637/T31638 router lift is designed
with clamping plates (see Figure 4) that accept
router body diameters of 3.200", 3.500", or 4.200."
Each one of the four clamping plates has two
curved edges—one deep and one shallow.
Through a process of trial and error, determine
which curvature best holds your router in position.
Do not mix and match shallow and deep curves
or the router will not be centered over the hole in
the mounting plate, and you run the risk of hitting
the plate with a bit during operations.
For larger router bodies, remove the clamping
plates completely (see Figure 5) and use the
clamp block and slide block to secure the router
in position.
Clamping Plates
To install router:
Insert crank handle in index ring on mount-
1.
ing plate (see Figure 1 on Page 4) and turn
clockwise until lift just touches the bottom of
the plate.
2. Place lift assembly upside down on two
blocks of wood (see Figure 6) so router collet
will be able to extend through the center hole
in the mounting plate.
3. Loosen (4) cap screws that secure clamp
block to slide block (see Figure 6).

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 precautions are overlooked or ignored, serious personal injury may occur.
-15-
Table T-Slots
Many router tables include one or more T-slots
(see Figure 12) for attaching accessories like a
miter gauge, jig, or featherboard.
T-slots
Figure 12. Example of T-slots featured on a
router table.
Squaring Fence
& Table T-Slot
When using a miter gauge, it is important to make
sure the fence is parallel with the table T-slot. This
will help ensure that the workpiece does not bind
or kick back during operation. If your router table
has a T-slot, use a fine ruler to make the distance
equal between the fence and the T-slot along the
full length of the table (see Figure 13).
To avoid workpiece kickback or binding
when using a miter gauge, ALWAYS make
sure fence is parallel with table T-slot before
beginning routing operations.

Edge Jointing
Jointing the edge of a board requires a straightcutting 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 router bit.

Profile Routing Routing Small Stock
Profile router bits are used to shape the edges
of a workpiece and give them a more decorative appearance. Some examples include beading, cove, chamfer, ogee, and moulding bits. By
changing the depth of cut and the cutting height,
many different shapes can be cut with each bit.
To cut a profile into a workpiece:

facturer's instructions.

Outfeed Fence
Infeed Fence
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:

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
injur y.

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 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.
To reduce the likelihood of kickback when freehand routing, use the starting pin or a block (see
Figures 21–22 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.
