Additional Safety for Metal Belt Grinders

Serious injury or death can occur from fingers, clothing, jewelry, or hair getting pinched/entangled in rotating belt or other moving components. Abrasion injuries can occur from touching moving abrasive belt with bare skin. Workpieces or ground-off particles thrown by abrasive belt can strike operator or bystanders, causing impact injuries, burns, or blindness. Flying sparks can ignite nearby explosive or flammable materials. Long-term respiratory damage can occur from using grinder without wearing a respirator. To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.

USE FOR INTENDED PURPOSE. This machine

is designed for grinding carbon steel, tool steel, and stainless steel. DO NOT use it to grind nonmetal materials.

DUST, SPARKS, & HOT MATERIALS. Grinding creates large amounts of airborne dust particles and sparks that can cause eye injury, respiratory illness, or burns. Grinding friction will cause workpiece to quickly get hot, causing burns to skin. Reduce your risk by always wearing approved eye, respiratory, and skin protection when using grinder. Use spark trap and adjust eye shields to best protect against sparks. Never allow anyone to stand in path of sparks. Do not touch freshly ground surfaces or nearby areas without first cooling them or allowing them to cool.

TOXIC MATERIALS. Exposure to certain dusts or fumes, like those from lead, asbestos, crystalline silica, tantalum, hafnium, niobium, titanium, etc., can result in potentially deadly health effects. Research toxic effects of materials you work with, and always seek to minimize/eliminate exposure to yourself and others.

WORKPIECE INTEGRITY & SUPPORT. Grinding fragile workpieces can result in loss of control, resulting in abrasion injuries, pinch/impact injuries, or damage to abrasive belt. Only grind solid workpieces that can withstand power grinding forces. Avoid grinding workpieces without flat bottom surfaces unless some type of jig is used to maintain support and control when grinding force is applied. Always use a jig or other holding device when grinding small workpieces, and keep hands and fingers at least 2" away from abrasive surface. Always grind with workpiece firmly against rest or another support device, if feasible.

FLAMMABLE MATERIALS. Grinding causes sparks that can ignite flammable or combustible materials near machine. Fine metal dust particles can ignite, depending on material type and circumstances. Aluminum, titanium, niobium, tantalum, zirconium, hafnium, etc. produce flammable dust. Learn fire hazards of materials you are using and be prepared to effectively fight a combustible metal fire. Do not use grinding belt for multiple material types and clean spark trap between mate rials. Never use this machine to grind magnesium.

IN-RUNNING NIP POINTS. Gap between moving belt and tool rest/table creates pinch point for fingers or workpieces; the larger the gap, the greater risk of fingers or workpieces getting caught in it. Minimize risk of pinch and crush injuries by adjusting tool rest/table to within

ABRASIVE BELT. Worn or damaged abrasive belts can fly apart and throw debris, or aggressively grab workpiece, causing injury from operator loss of workpiece control. Always inspect belt before operation and replace if worn or damaged. Rotating belt can remove skin quickly. Always keep hands away from moving belt during operation.

Model G0972 (Mfd. Since 10/23)

⁄16 " of belt.

FEEDING WORKPIECE. Forcefully jamming workpiece into abrasive surface could cause it to be grabbed aggressively, pulling hands into abrasive surface. Avoid introducing sharp edges into moving belt on leading side of workpiece. Properly support workpiece and only grind against direction of abrasive belt travel. Firmly grasp workpiece or holding jig in both hands and ease workpiece into belt using light pressure.

AVOIDING ENTANGLEMENT. Becoming entangled in moving parts can cause severe injury or death. Keep all guards in place and closed; DO NOT wear loose clothing, gloves, or jewelry; and tie back long hair.

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.)

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

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

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:

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.

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!

Site Considerations

Weight Load

Refer to the of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual.

See below for required space allocation.

Physical Environment

The physical environment where the machine is operated is important for safe operation and longevity of machine components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41°–104°F; the relative humidity range exceeds 20%–95% (non-condensing); or the environment is subject to vibration, shocks,

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

Workpiece Inspection

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

workpieces for the following:

• Flammable Workpiece: Workpieces with

unstable chemical elements (like magnesium) may catch fire or create explosion hazards when introduced to the heat and friction of grinding. Be aware of the material composition of workpieces you intend to use and avoid grinding different metals and alloys on the same belt in case two different materials create a dangerous chemical reaction.

• Soft Workpiece: Workpieces that are made

of aluminum, brass, lead, and other nonferrous metals will load up in the belt. Grinding plastics, rubber, fiberglass, or other soft materials can also cause the same problem. Always use the recommended belt for the material.

• 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 contact with the belt. This hazard must be avoided.

• Wood Workpiece: Never grind wood on

this machine. Wood dust and shavings are extremely flammable and hot metal sparks will ignite them. A belt that has been used to sand wood creates a flame and explosion hazard when the hot sparks created by grinding metal are introduced.

Grinding Tips

• Extend the life of the abrasive belt by regularly using an abrasive surface cleaner. Change a belt when cleaning is no longer effective.

• As a rule-of-thumb, grind with progressively higher grit numbers. A higher grit will achieve a finer finish.

• Hold workpiece securely with both hands and do not wear gloves. Use tool rest and jigs whenever possible to support workpiece. Do not force workpiece against belt.

• Never grind magnesium. Once shaved or powdered, it is highly flammable, and a magnesium fire is difficult to put out.

• Remember that grinding metal often produces sparks. DO NOT grind metal near flammable materials, and be aware of the area around the machine the sparks will reach.

• Use full width of belt by moving the workpiece back-and-forth across the belt.

• Make sure belt guards/covers are secured during operation.

• The workpiece will get hot as you continue to grind. Cool the workpiece frequently by quenching in water or another approved solution.

• Wear the proper protective clothing. Prepare for particles to be expelled from the grinder at high speeds. Wear safety glasses, face shield, dust mask, earplugs, leather apron, and heavy leather boots.

Model G0972 (Mfd. Since 10/23)

Moving belt can cause serious personal injury if it comes in contact with fingers, hands, or other body parts. Always support workpiece against tool rest when grinding if possible. Use extreme care to provide a safe distance between belt and any body part.

Page 28

Choosing

Abrasive Belts

This machine uses a 3" x 783⁄4" belt. Below is a chart that groups abrasives into different classes, and shows which grits fall into each class.

Depending on the material, some belts also come with different backing material. For grinding, cloth backing is the most common and has various weights. The "weight" of the cloth backing refers to the flexibility of the belt, and you will want to use a belt with flexibility tailored to your workpiece and application. The chart below illustrates common cloth weights and their flexibility/uses.

Grit Class

24–60 Extra Coarse

60 –120 Coarse

120–180 Medium

180+ Fine

The general rule of thumb is to grind a workpiece with progressively higher grit numbers. Avoid skipping grits; the larger the grit increase, the harder it will be to remove the scratches from the previous grit.

Ultimately, the type of metal you use and your stage of finish will determine the best grit types to install on your grinder.

Belts are also made with different materials, and your workpiece and intended operation will determine which belt material will produce the best results for you. The following chart illustrates some common belt materials and the situations that they are most effective.

Belt Weight Description

J-Weight Flexible. Good for contour

sanding/grinding.

X-Weight Medium flexibility. Strong. For

all-purpose sanding/grinding.

Y-Weight Least flexible. Very strong. Good

for heavy stock removal. Often waterproof and tear resistent.

Changing Frame Tilt

Change the upper machine frame to a vertical or horizontal position, depending on your operation.

With the frame vertical, it is easier to perform grinds perpendicular to the belt (i.e., with a workpiece flat against the table in Figure 29).

Belt Material Operation

Aluminum Oxide Finishing. Ferrous metals.

Zirconia Alumina Finishing; wet or dry

grinding. Ferrous metals, some steels.

Ceramic Aggressive grinding;

deburring. Heat-sensitive metals.

Silicon Carbide Cutting; stock removal; wet

or dry grinding. Cast iron, steel, non-ferrous metals.

Grinding

While the platen grinding attachment can only be used for flat or convex workpieces, the contact wheel grinding attachment allows for workpieces that are concave (see Figure 44).

Table Tilt

Figure 43. Table tilted.

When grinding very thin workpieces, a common practice when producing knife bevels, the workpiece can be drawn into the gap between the table and the belt. If a workpiece is too thin to be safely supported by the table, consider researching freehand belt grinding techniques or using a different method to grind your workpiece.

Table must always be adjusted within 1⁄16" of belt to reduce risk of fingers or workpiece being drawn into gap.

To adjust table tilt:

Adjusting

Platen to Wheels

Place straightedge across platen graphite

and idler wheels, as shown in Figure 75, and measure distance between each idler wheel and straightedge.

The platen should extend about the two idler wheels on the platen grinding attachment in order to produce flat and square grinds. Due to the force and abrasives of grinding, the platen wears as it is used, so you will occasionally need to adjust the platen forward in order for grinds to maintain this adjustment.
