NOTICE

Safety Instructions for Machinery

SECTION 1: SAFETY

-10- Model T32251/T32252 (Mfd. Since 08/20)

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.

Model T32251/T32252 (Mfd. Since 08/20) -11-

Additional Safety for Grinders

Serious injury or death can occur from impact injuries if grinding wheel breaks apart during use.

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

pinch points. Flying sparks can ignite explosive or flammable materials. Rotating grinding

wheels can easily remove skin. To minimize risk of getting hurt or killed, anyone operating

machine MUST completely heed hazards and warnings below.

STARTING GRINDER. If a wheel is damaged,

it will usually fly apart shortly after start-up. To

protect yourself, always stand to side of grinder

when turning it ON and allow it to run for at least

one minute before standing in front of it.

VISUAL INSPECTION. Verify that grinding wheels

are free of cracks, chips, or dents in wheel surface

before installing. Do not use wheel if it has any

of these problems or it could break apart during

operation.

WHEEL SPEED RATING. Wheels operated at a

faster speed than rated for may break apart dur-

ing operation. Before mounting a new wheel, be

sure wheel RPM rating is equal to or higher than

speed of grinder. Never use unmarked wheels or

wheel rated for a lower speed than grinder.

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.

SIDE & TOP GRINDING. Grinding on side of

wheels can cause them to crack and burst—unless

wheel is rated for side grinding. Grinding on top of

wheels greatly increases risk of workpiece kick-

back. Always grind on downward part of wheel.

WHEEL ATTACHMENT. Only use flanges includ-

ed with grinder when mounting wheels. Other

flanges may not properly secure wheel and

cause an accident. Do not use warped or dam-

aged flanges and always use paper discs (blot-

ters) between wheels and flanges to reduce risk

of flanges cracking wheel when tightened. Only

tighten wheel spindle nut enough to drive wheel

and prevent slippage.

EYE SHIELDS. Place eye shields close to grind-

ing wheel and re-adjust as wheel wears down.

TOOL REST POSITION. If tool rest is too far

away from wheel, it forms a gap called an "in-

running nip point" which may cause workpiece to

be pulled down, leading to loss of control and pull-

ing your hand into grinding wheel. Keep tool rest

within 1⁄8" from wheel when operating to minimize

risk of pinching and crushing injuries. Replace

grinding wheel when tool rest gap is wider than

1⁄8", and when no additional adjustment can be

made.

VIBRATING WHEEL. Never use a wheel that

vibrates. Replace wheel or shaft bearings

immediately.

HAND & WHEEL CONTACT. Keep a firm grip

on workpiece and position your hands a safe

distance away when grinding. Anticipate when

workpiece will heat up, and cool it before it

becomes too hot to hold, or use an appropriate

clamp. Avoid wearing gloves as they may get

caught in grinding wheel and cause even more

serious entanglement injuries.

RING TEST. Perform a "ring test" on grinding

wheels before installation to ensure they are safe

to use. A wheel that does NOT pass ring test may

break or fly apart during operation.

EYE, FACE, & LUNG PROTECTION. Grinding

ejects small particles at a high rate of speed.

These particles can cause blindness, skin injuries

or respiratory damage. ALWAYS wear approved

clothing, safety goggles, face shield, and a respi-

rator for type of grinding to be done.

SAFE MOUNTING & WORK AREA. An unse-

cured grinder may become dangerously out of

control during operation. Before use, verify grinder

is FIRMLY secured in a location free of explosive

or flammable materials. Frequently clean grinding

dust from beneath grinder and inside wheel cover.

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 (T32251) ..... 3 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.

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.)

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

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.

Full-Load Current Rating (T32252) ..... 6 Amps

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 (T32251) ...........16 AWG

Minimum Gauge Size (T32252) ...........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 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.

Children and visitors may be

seriously injured if unsuper-

vised around this machine.

Lock entrances to the shop

or disable start switch or

power connection to prevent

unsupervised use.

Workbench Load

Refer to the Machine Data Sheet for the weight

and footprint specifications of your machine.

Some workbenches may require additional rein-

forcement to support the weight of the machine

and workpiece materials.

Consider anticipated workpiece sizes and addi-

tional space needed for auxiliary stands, work

tables, or other machinery when establishing a

location for this machine in the shop. Below is

the minimum amount of space needed for the

machine.
