power, but it can be converted for 220V operation.

220V conversion consists of installing the correct

plug and 220V LED work light, as outlined in Full

220V Conversion.

Note: The 110V LED work light connections will

burn out with a 220V power supply, but the light

assembly can be removed altogether instead of

being replaced. Refer to Partial 220V Conversion

for instructions.

Wiring diagrams are provided in the back of this

manual showing the Model T32255 wired for both

110V and 220V. Refer to these diagrams begin-

ning on Page 28 of owner's manual when follow-

ing this procedure.

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

Model T32255 (Mfd. Since 12/20) -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 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.

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.

Additional Safety for Buffers

WORKPIECE SELECTION. Always inspect the

condition of your workpiece. DO NOT buff pieces

with loose knots, large splinters, sharp edges, and

DO NOT buff knives, cable, chain or other poten-

tially dangerous objects that may be grabbed by

the buffing wheel and thrown at the operator.

EYE/FACE/LUNG PROTECTION. Always wear

eye protection or a face shield and a heavy

leather apron when operating the buffer. Wear a

dust mask to protect your lungs from microscopic

particulates. Particulates may cause allergies or

long-term respiratory health problems.

MOUNTING TO BENCH/STAND. An unsecured

buffer may become dangerously out of control

during operation. Make sure buffer is FIRMLY

secured to a bench/stand before use.

WORKPIECE CONTROL. If you cannot hold

small workpieces securely, do not buff them with

this machine. Secure them with clamps or similar

jigs or use a different buffer.

AVOIDING ENTANGLEMENT. Becoming entan-

gled in moving parts can cause severe injury or

death. Keep all guards and covers in place; DO

NOT wear loose clothing, gloves, or jewelry; and

tie back long hair.

OPERATOR POSITION. Do not stand directly in

front of the buffer when turning the machine ON,

or when buffing. Do not buff material at the rear

of the machine.

HAND/WHEEL CONTACT. Do not allow your

hands to come into contact with the buffing wheel.

Abrasive accessories can remove skin fast. Keep

a firm grip on the workpiece and position your

hands at a safe distance away when buffing.

Avoid wearing gloves as they may get caught in

the buffer and cause entanglement injuries.

CORRECT ACCESSORIES AND USE. The buf-

fer is only designed for buffing and polishing.

Never exceed the maximum speed listed on each

buffing wheel.

WORKPIECE FEED. Allow the wheel to reach

full speed, then slowly ease the workpiece into

the buffing wheel, holding it in front of and

slightly below the wheel center. Do not place

the workpiece on the top or sides of the buffing

wheel and do not place an edge or corner of

the workpiece against the buffing wheel, or jam

it against the wheel. The workpiece may eject

toward the operator or be torn from the operator’s

hands, causing serious personal injury.

Entanglement/amputation injuries can occur from being caught in moving parts or in-running

pinch points. Buffer can easily remove skin. To minimize risk of getting hurt or killed, anyone

operating machine MUST completely heed hazards and warnings below.

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 110V ........ 7 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.

Full-Load Current Rating at 220V .... 3.5 Amps

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.

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.)

-10- Model T32255 (Mfd. Since 12/20)

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.

Grounding Requirements

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.

ure). The plug must only be inserted into a match-

ing receptacle (outlet) that is properly installed

and grounded in accordance with all local codes

and ordinances.

For 220V operation: The plug specified under

“

Circuit Requirements for 220V” on the previous

page has a grounding prong that must be attached

to the equipment-grounding wire on the included

power cord. The plug must only be inserted into

a matching receptacle (see following figure) that

is properly installed and grounded in accordance

with all local codes and ordinances.

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.

NOTICE

If you cannot find an item on this list, care-

fully check around/inside the machine and

packaging materials. Often, these items get

lost in packaging materials while unpack-

ing or they are pre-installed at the factory.

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:

Put on safety glasses.

2. 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.

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.
