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.

VIBRATING WHEEL. Never use a wheel that vibrates. Replace wheel or shaft bearings immediately.

WHEEL SPEED RATING. Wheels operated at a

faster speed than rated for may break apart during 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 entangled 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 kickback. Always grind on downward part of wheel.

TOOL REST POSITION. If tool rest is too far away from wheel, it forms a gap called an "inrunning nip point" which may cause workpiece to be pulled down, leading to loss of control and pulling your hand into grinding wheel. Keep tool rest within risk of pinching and crushing injuries. Replace grinding wheel when tool rest gap is wider than

1

made.

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 SHIELDS. Place eye shields close to grinding wheel and re-adjust as wheel wears down.

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 respirator for type of grinding to be done.

⁄8" from wheel when operating to minimize

⁄8", and when no additional adjustment can be

WHEEL ATTACHMENT. Only use flanges included with grinder when mounting wheels. Other flanges may not properly secure wheel and cause an accident. Do not use warped or damaged flanges. Only tighten wheel spindle nut enough to drive wheel and prevent slippage.

Model T32002 (Mfd. Since 02/20)

SAFE MOUNTING & WORK AREA. An unsecured 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.

Additional Safety for Buffers

Entanglement/amputation injuries can occur from being caught in moving parts or in-running pinch points. Rotating buffing wheel can easily remove skin. To minimize risk of getting hurt or killed, anyone operating machine MUST completely heed hazards and warnings below.

CORRECT ACCESSORIES AND USE. Never

install a grinding wheel on buffing side of machine. Buffer is only designed for buffing and polishing. Never exceed maximum speed listed on each buffing/polishing wheel.

HAND/WHEEL CONTACT. DO NOT allow hands to contact buffing wheel. Abrasive accessories can remove skin fast. Keep firm grip on workpiece and keep hands at a safe distance away when buffing. If workpiece is small or difficult to hold, use a workpiece holding fixture.

WORKPIECE SELECTION. Always inspect condition of workpiece. DO NOT buff pieces with loose knots, large splinters, sharp edges, and DO NOT buff knives, cable, chain or other potentially dangerous objects that may be grabbed by buffing wheel and thrown at operator.

WORKPIECE FEED. Allow wheel to reach full speed, then slowly ease workpiece into wheel, holding it in front of and slightly below wheel center. Do not place workpiece on top or sides of wheel and do not place edge or corner of workpiece against wheel, or jam it against wheel. Workpiece may eject toward operator or be torn from hands, causing serious personal injury.

EYE, FACE, & LUNG PROTECTION. Always wear eye protection or face shield and heavy leather apron when operating buffer. Wear dust mask to protect lungs from microscopic particulates as they may cause allergies or long-term respiratory health problems.

MOUNTING TO BENCH/STAND. An unsecured machine may become dangerously out of control during operation. FIRMLY secure machine to bench/stand before use.

WORKPIECE CONTROL. If you cannot hold small workpieces securely, do not buff them with this machine. Secure workpiece with clamps or jigs or use different machine.

AVOIDING KICKBACK. Avoid kickback by buffing in accordance with wheel rotation. Always buff on downward side of wheel and keep wheel cover in place. Avoid buffing with excessive force.

DISCONNECT POWER WHEN SERVICING. Disconnect machine from power and allow wheel to come to complete stop before service, maintenance, or adjustments. Avoid pulling cord-connected machinery from cord–instead, grasp plug when disconnecting from power.

AVOIDING ENTANGLEMENT. Becoming entangled 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.

-12-

OPERATOR POSITION. DO NOT stand directly in front of buffer wheel when turning machine ON, or when buffing. Do not buff material at rear of machine.

Model T32002 (Mfd. Since 02/20)

Additional Safety for Rotary Attachments

Entanglement injuries can occur from being caught in moving parts. Rotating attachments can easily remove skin. Flying sparks from grinding can ignite explosive or flammable materials. To minimize risk injury, completely heed warnings below.

AVOIDING ENTANGLEMENT. Becoming entan-

gled in moving parts can cause severe injury or death. DO NOT wear loose clothing, gloves, or jewelry; and tie back long hair.

EXPLOSION HAZARDS. Sparks while using grinding bit can easily ignite flammable gasses, fluids, or materials. ALWAYS make sure these substances are completely removed from work area before operation.

TOOL CAPACITIES. A LWAYS op er a te th is at ta chment with bits and tools rated for the capacities stated on data sheet.

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.

STARTUP INJURIES. Grinding wheel, buffing

wheel, and rotary attachment all power up and spin at the same time. ALWAYS remove rotary attachment when not in use to avoid accidental injur y.

WORKPIECE CONTROL. If spinning tool slips from workpiece during operation, piercing or abrasion injury could occur. Secure workpiece in vise or clamp before starting rotary tool. Jamming tool against workpiece could cause workpiece or tool to shatter and send debris in all directions. Firmly grasp rotary tool and ease it into workpiece.

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 personal injury, damage to equipment, or poor work results.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability 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.

or equipment damage

may occur if machine is

not properly grounded

and connected to power

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.

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 overloading 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

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, consult 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 supply 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.)

Model T32002 (Mfd. Since 02/20)

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 necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel 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, disconnect it from power, and immediately replace it with a new one.

We do not recommend using an extension cord with this machine. 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:

Workpiece

Selecting

Inspection

Some workpieces are not suitable for grinding on a bench grinder. Before grinding, inspect all

workpieces for the following:

• Hard Workpiece: Workpieces that are made of stone, carbide, stainless steel, ceramics, glass, or have hardened welds will wear out most general-grade grinding wheels quickly. If hard materials are to be ground, you must install the correct type of grinding wheel.

• Soft Workpiece: Workpieces that are made of aluminum, brass, lead, and other nonferrous metals will load up in the grinding wheel and render the abrasive useless. Grinding wood, plastics, rubber, fiberglass, or other soft materials can also cause the same problem and lead to the wheel overheating and possibly bursting during use if ignored. To restore a loaded grinding wheel surface, redress with a dressing tool.

Grinding Wheel

The Model T32002 only accepts Type 1 wheels with a

Aluminum oxide and silicon carbide wheels are marked in a somewhat uniform manner by all the major manufacturers. Understanding these markings will help you understand the capabilities of various wheels. Always refer to the manufacturer’s grinding recommendations when selecting a wheel for your project.

The basic format for wheel numbering is:

The Prefix is the manufacturer’s designation for a particular wheel type (eg. Type 1 wheels).

Prefix

Abrasive

Typ e

1 A 60 L V

Grit Size Grade

Typ e

• Flexible/Unstable Workpiece: Grinding on the side or the ends of cable, chain, or round workpieces creates the hazard of workpiece twist or grab, leading to entanglement with the wheel or shaft. This hazard must be avoided.

• Loose Parts: Make sure that the workpiece is free of any parts like springs, pins, balls, or other components that may loosen or dislodge during grinding, and hit the operator.

• Strength: Make sure that the workpiece is strong enough to be ground. Should it break, the broken piece may dig into the wheel and cause kickback or severe injury.

Electrical system is not waterproof. DO NOT use this grinder with a liquid cooling system required for wet grinding wheel operations. Ignoring this warning can lead to electrocution or machine damage.

The most common Abrasive Types used are A for Aluminum Oxide, C for Silicon Carbide, and occasionally SG for Seeded Gel.

The Grit Size is a number that refers to the size of the abrasive grain in the wheel. The lower the number, the coarser the wheel. Ten is a very coarse wheel for roughing and 220 is usually the upper range for fine finish work.

Grade is an indication of the hardness of the wheel—“A” being the softest and “Z” being the hardest.

Bond Type refers to the type of bonding material used to hold the abrasive material. Most general purpose wheels will have a “V” indicating Vitrified Clay is used. Vitrified Clay provides high strength and good porosity. The other common bond type is “B” for resin where synthetic resins are used. These are used to grind cemented carbide and ceramic materials.

Note: There may be other numbers inserted that have meaning for a particular type of wheel. Refer to the manufacturer’s technical data for a complete explanation.

Caring for

Inspecting

Grinding Wheel

When grinding, your safety depends, to a large degree, on the condition of the wheel. A wheel in poor condition presents the possibility of breaking apart during rotation and injuring the operator and others in the area.

Tips to help you avoid breaking the wheel:

• Always transport, store and handle wheels with care. Wheels may be damaged if they are dropped or if heavy objects are stacked on them.

• Select right grinding wheel for job. DO NOT grind material inappropriate for wheel type.

• Only use wheels that are rated for RPM of tool grinder.

• Mount wheel properly (see Installing/ Removing Grinding Wheel on Page 22).

• DO NOT push tooling into grinding wheel with such force that it causes grinder to bog down. And do not apply pressure to stop wheel after turning grinder OFF.

• Dress wheel when necessary. Do not allow it to become glazed (see Dressing Grinding Wheel on Page 22).

• DO NOT store wheels in damp or wet locations.

Grinding Wheel

Before mounting a new grinding wheel, it must be inspected. Do not assume that a wheel is in sound condition just because it is new—often damage can occur in shipping, with age, or with exposure to moisture.

First, do a Visual Inspection. Look for any cracks, chips, nicks or dents in the surface of the wheel. If you see any of these, DO NOT use the wheel.

Second, do a Ring Test. This test will give you an indication of any internal damage that may not be obvious during a visual inspection.

To perform ring test:

Make sure grinding wheel tested is clean and

1.

dry; otherwise, you may get false results.

If size permits, balance grinding wheel with

2.

your finger in mounting hole. If this is not possible, hang wheel in air with a piece of cord or string looped through mounting hole.

3. At spots shown in Figure 11, gently tap grind- ing wheel with a light non-metallic device such as handle of a screwdriver or a wooden mallet.

Note: Finding exact spot to tap will take sev-

eral attempts.

• DO NOT overtighten nut when mounting the wheel.

• DO NOT leave wheel mounted when machine is not in use.

Installing/Removing

Grinding Wheel

— If you determine from ring test that grind-

ing wheel is damaged, DO NOT use it!

Dressing

Grinding Wheel

Depending on the type of grinding you do, the grinding wheel may require periodic dressing.

There are several different types of wheel dressing devices available on the market (see Accessories on Page 27 for examples). Dressing restores the abrasive quality of the wheel surface and brings the wheel edge back to a square form.

Refer to the instructions that accompany your dressing accessory for complete details on how to properly dress the wheel.

Wheels with varying grit are useful for different operations and workpiece materials. DO NOT leave wheel mounted when machine is not in use.

ALWAYS visually inspect and perform a “ring test” on a wheel before installing. DO NOT use damaged wheels!

To install/remove grinding wheel:

DISCONNECT MACHINE FROM POWER!

1.

2. Remove outer grinding wheel guard by loos-

ening (3) M5-.8 x 5 Phillips head screws with (3) lock washers holding wheel guard in place (see Figure 12).

Always adjust tool rest after dressing or replacing grinding wheel. Failure to do so could lead to workpiece kickback and injury.

Storing

Grinding Wheel

Grinding wheels can be easily damaged, so it is important to store them properly. Follow all wheel manufacturer storage instructions. Always store grinding wheels in a location that is dry and protected from potential damage due to them being dropped or having other items dropped on them. Also, avoid storing grinding wheels where there is high humidity, extreme heat or cold, or solvents.

standoff stud snugly but do not over-tighten.

Overtightening grinding wheel can stress and crack wheel. Cracked wheel can become deadly projectiles when machine is turned on.

8. Re-assemble outer wheel guard using hard-

ware removed in Step 2.

While standing to side of the machine, turn

Buffing

Below are some quick tips for getting the most out of your buffing wheel. Remember, there is no substitute for experience. Learning how to hold the workpiece, how much pressure to apply, and how to move the workpiece against the wheel requires a certain amount of trial-and-error.

• Thoroughly clean all parts you plan to buff. Dirt, oil, rust, paint, or other film must be removed chemically or with water. Make sure to dry off parts with a rag after cleaning.

Installing/Removing

Buffing Wheel

This machine has a long spindle shaft that allows for mounting many buffing accessories, depending on your application.

To install/remove buffing wheel:

1. DISCONNECT MACHINE FROM POWER!

2. Remove M8-1.25 hex nut (see Figure 15).

• To begin buffing, slowly feed workpiece into buffing wheel. Hold workpiece tightly at all times while buffing. Placing one hand near contact point will give you better control.

• Wear safety equipment when buffing. If buffer forces workpiece out of your hand, be prepared for it to come flying at you! Wear safety glasses or a face shield and a heavy leather apron. Also, wear a dust mask to protect your lungs from microscopic particulate that will be flying off wheel.

Use caution when polishing plated metals; there is a chance that thinly-plated materials could be damaged. Light pressure is all that is needed for quality work.

Note: Spindle shaft on left side of grinder has

left-hand threads. Turn clockwise to loosen.
