This manual provides critical safety instructions on the proper setup,

operation, maintenance, and service of this machine/tool. Save this

document, refer to it often, and use it to instruct other operators.

Failure to read, understand and follow the instructions in this manual

may result in fire or serious personal injury—including amputation,

electrocution, or death.

The owner of this machine/tool is solely responsible for its safe use.

This responsibility includes but is not limited to proper installation in

a safe environment, personnel training and usage authorization,

proper inspection and maintenance, manual availability and compre-

hension, application of safety devices, cutting/sanding/grinding tool

integrity, and the usage of personal protective equipment.

The manufacturer will not be held liable for injury or property damage

from negligence, improper training, machine modifications or misuse.

Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities contains chemicals known to the State

of California to cause cancer, birth defects or other reproductive

harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you

do this type of work. To reduce your exposure to these chemicals:

Work in a well ventilated area, and work with approved safety equip-

ment, such as those dust masks that are specially designed to filter

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.

For Your Own Safety, Read Instruction

Manual Before Operating This Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions.

This manual uses a series of symbols and signal words intended to convey the level of impor-

tance of the safety messages. The progression of symbols is described below. Remember that

safety messages by themselves do not eliminate danger and are not a substitute for proper

accident prevention measures. Always use common sense and good judgment.

Indicates a potentially hazardous situation which, if not avoided,

MAY result in minor or moderate injury. It may also be used to alert

against unsafe practices.

Indicates a potentially hazardous situation which, if not avoided,

COULD result in death or serious injury.

Indicates an imminently hazardous situation which, if not avoided,

WILL result in death or serious injury.

Alerts the user to useful information about proper operation of the

machine to avoid machine damage.

NOTICE

Safety Instructions for Machinery

SECTION 1: SAFETY

-10-

Model T28780 T28781 (Mfd. Since 06/19)

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 (570) 546-9663.

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.

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 ampu-

tation 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 dis-

connect it and safely store it out of way.

APPROPRIATE WORKPIECES. Danger of kick-

back 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 start-

ing router.

INSTALLING ROUTER BIT. Insert at least

⁄4 of

bit shank into collet, and allow

⁄8" of clearance

between shank and bottom of collet to ensure bit

is securely installed.

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 oper-

ate 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 work-

piece 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 recom-

mended speed of any router bit. Doing so can

cause bit to fracture or explode and cause injury.

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.

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.)

110V Circuit Requirements

This machine is prewired to operate on a power

supply circuit that has a verified ground and meets

the following requirements:

Nominal Voltage .................... 110V, 115V, 120V

Cycle

..........................................................60 Hz

Phase

........................................... Single-Phase

Power Supply Circuit

......................... 15 Amps

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.

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.

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 ...........................14 AWG

Maximum Length (Shorter is Better).......50 ft.

SHOCK HAZARD!

Two-prong outlets do not meet the grounding

requirements for this machine. Do not modify

or use an adapter on the plug provided—if

it will not fit the outlet, have a qualified

electrician install the proper outlet with a

verified ground.

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.

This machine is equipped with a power cord that

has an equipment-grounding wire and a grounding

plug. Only insert plug into a matching receptacle

(outlet) that is properly installed and grounded in

accordance with all local codes and ordinances.

DO NOT modify the provided plug!

The Models T28780 & T28781 include an ON/

OFF paddle switch with disabling key. 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. See Connecting Power Cords on Page

T23692—Orange Power Degreaser

A great product for removing the waxy ship-

ping grease from the non-painted parts of the

machine during clean up.

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:

Put on safety glasses.

Coat the rust preventative with a liberal

amount of cleaner/degreaser, then let it soak

for 5–10 minutes.

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.

Repeat Steps 2–3 as necessary until clean,

then coat all unpainted surfaces with a quality

metal protectant to prevent rust.

Gasoline and petroleum

products have low flash

points and can explode

or cause fire if used to

clean machinery. Avoid

using these products

to clean machinery.

Many cleaning solvents

are toxic if inhaled. Only

work in a well-ventilated

area.

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.
