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 or blindness. Long-term respiratory
damage can occur from using grinder without wearing a respirator. To reduce the risk of these
hazards, operator or bystanders MUST completely heed the hazards and warnings below.
IN-RUNNING NIP POINTS. The gap between
moving abrasive belt and rest/support creates a
pinch point for fingers or workpieces; the larger this
gap is, the greater the risk of fingers or workpieces
getting caught in it. Minimize the risk of pinch and
crush injuries by adjusting rest/support to no more
1
⁄16 " away from belt.
than
GRINDING DUST. Grinding creates large amounts
of airborne dust particles that can cause eye injury
or respiratory illness. Reduce your risk by always
wearing approved eye and respiratory protection
when using grinder.
ABRASIVE CONDITION. 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.
HOT WORKPIECES. Grinding friction will cause
workpiece to quickly get hot, causing burns to the
Wear apron if grinding for an extended time.
skin.
Do not touch freshly ground surfaces or nearby
areas without first cooling them or allowing them
to cool.
MINIMUM STOCK DIMENSION. Small
workpieces can be aggressively pulled from your
hands, causing contact with belt surface. Always
use a jig or other holding device when grinding
small workpieces, and keep hands and fingers at
least 2" away from abrasive surface.
FLAMMABLE MATERIALS. Grinding metal will
cause sparks. Make sure there are no flammable
or combustible materials near machine.
ABRASIVE DIRECTION. Feeding workpiece
incorrectly can cause it to be thrown from machine,
striking operator or bystanders, or causing hands
to slip into moving belt. To reduce these risks,
only grind against direction of abrasive belt travel,
ensure workpiece is properly supported, and
avoid introducing sharp edges into moving belt on
the leading side of the workpiece.
PROTECTING HANDS. Rotating belt can remove
skin quickly. Always keep hands away from moving belt during operation. Do not wear gloves while
grinding. Stop machine before cleaning dust from
work area and protect hands because pieces can
be sharp.
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. Properly support workpiece; 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
grind with workpiece firmly against rest or another
support device, if feasible.
Model T32459 (Mfd. Since 12/23)
FEEDING WORKPIECE. Forcefully jamming
workpiece into abrasive surface could cause it
to be grabbed aggressively, pulling hands into
abrasive surface. Firmly grasp workpiece in both
hands and ease it 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 & Plug Requirements
Two-prong outlets do not meet the
grounding requirements for this machine.

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 T32459 (Mfd. Since 12/23)
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.
-19-
Choosing
Grinding Belts
This machine uses a 2" x 42" 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.
GritClass
24–60Extra Coarse
60 –120Coarse
120–180Medium
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 chart below illustrates some
common belt materials and the situations that
they are most effective.
Belt Weight Description
J-WeightFlexible. Good for contour
sanding/grinding.
X-WeightMedium flexibility. Strong. For
all-purpose sanding/grinding.
Y-WeightLeast flexible. Very strong. Good
for heavy stock removal. Often
waterproof and tear resistent.
Adjusting Frame Tilt
The Model T32459 frame can be positioned from
0°–90°, depending on your operation. With the
frame at a vertical angle (see Figure 20), it is
easier to perform grinds perpendicular to the belt
(i.e., with a workpiece flat against the tool rest in
Figure 20).

Adjusting Tool Rest
The tool rest should be used whenever it can feasibly be installed to help support the workpiece.
Once installed, it can be tilted from 5° left to 120°
right, can be swiveled on its base, and can adjust
toward and away from the machine frame. These
adjustments allow for angled workpieces and for
the rest to be adjusted square to the platen regardless of how the frame and platen are adjusted.
When grinding very thin workpieces, a common practice when producing knife bevels, the
workpiece can be drawn into the gap between the
tool rest and the belt. If a workpiece is too thin
to be safely supported by the tool rest, consider
researching freehand belt grinding techniques or
using a different method to grind your workpiece.

workpiece, as shown in Figure 40, and
slowly feed it into moving belt with light, even
pressure. DO NOT force workpiece against
belt.
Note: There are many different techniques
for using belt to grind and sharpen knives.
Whichever one you use, make sure that you
hold knife firmly and ease it into belt without
excessive pressure to ensure safe operation.
This setup is good for material removal and creating profiles. Regardless of your workpiece, always
use two hands to control the workpiece and use
the tool rest to support it, if feasible.

Adjusting
Platen to Wheels
The platen should extend about 1⁄8" forward from
the two front idler wheels 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.

These pages are current at the time of printing. However, in the spirit of improvement, we may make changes to the electrical systems of future machines. Compare the manufacture date of your machine to the one
stated in this manual, and study this section carefully.
If there are differences between your machine and what is shown in this section, call Technical Support at
(570) 546-9663 for assistance BEFORE making any changes to the wiring on your machine. An updated
wiring diagram may be available.
number and manufacture date of your
machine before calling. This information can be found on the main machine label.
SECTION 8: WIRING
Note: Please gather the serial
Wiring Safety Instructions
SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical components!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
This includes the installation of unapproved aftermarket parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires disconnected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious personal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.
