SAFETY
Additional.Safety.for.Belt.Sanders
Serious injury or death can occur from fingers, clothing, jewelry, or hair getting entangled in
moving
belt, spindle, or other components. Abrasion injuries can occur from touching moving
sandpaper with bare skin. Incorrect feeding of workpiece can lead to workpiece being thrown and
striking operator or bystanders with enough force to cause impact injuries. Long-term respiratory
damage can occur from using sander without proper use of a respirator. To reduce the risk of these
hazards, operator or bystanders MUST completely heed the hazards and warnings below.
WORKPIECE INSPECTION. Nails, staples, knots, or
other imperfections in workpiece can be dis-
lodged and thrown from sander at a high rate of
speed at people, or cause damage to sandpaper
or sander. Never sand stock that has embedded
foreign objects or questionable imperfections.
SANDPAPER CONDITION. Worn or damaged sand-
paper can fly apart and throw debris at opera-
tor, or aggressively grab workpiece, resulting in
subsequent injuries from operator loss of work-
piece control. Always inspect sandpaper before
operation and replace if worn or damaged.
IN-RUNNING NIP POINTS. The gap between mov-
ing sandpaper and fixed table/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 this
risk by adjusting table/support to no more than
1
⁄16"
away from sandpaper. For spindle sanders,
always use the table insert that fits closest
diameter of installed drum.
WORKPIECE INTEGRITY. Sanding fragile work-
pieces can result in loss of control, resulting in
abrasion injuries, impact injuries, or damage
to sandpaper. Only sand solid workpieces that
can withstand power sanding forces. Make sure
workpiece shape is properly supported; avoid
sanding workpieces without flat bottom sur-
faces unless a jig is used to maintain support
and control when sanding force is applied.
SANDING DUST. Sanding creates large amounts of
dust that can lead to eye injury or respiratory
illness. Reduce your risk by always wearing
approved eye and respiratory protection when
using sander. Never operate without adequate
dust collection system in place and running.
Howe ver, dust collection is not a substitute for
using a respirator.
SANDPAPER DIRECTION. Feeding workpiece incor-
rectly can cause it to be thrown from machine,
striking operator or bystanders, or causing your
hands to slip into the moving sandpaper. To
reduce these risks, only sand against direction
of sandpaper travel, ensure workpiece is prop-
erly supported, and avoid introducing sharp
edges into moving sandpaper on the leading
side of the workpiece.
HAND PLACEMENT. Rotating sandpaper can
remove a large amount of flesh quickly. Always
keep hands away from sandpaper during opera-
tion. Never touch moving sandpaper on pur-
pose. Use a brush to clean table of sawdust
and chips.
FEEDING WORKPIECE. Forcefully jamming work-
piece into sanding surface could cause it to be
grabbed aggressively, pulling hands into sanding
surface. Firmly grasp workpiece in both hands
and ease it into sandpaper using light pressure.
AVOIDING ENTANGLEMENT. Becoming entangled
in moving parts can cause pinching and crush-
ing injuries. To avoid these hazards, keep all
guards in place and closed. DO NOT wear loose
clothing, gloves, or jewelry, and tie back long
hair.
WORKPIECE SUPPORT. Workpiece kickback can
occur with violent force if workpiece is not
properly supported during operation. Always
sand with workpiece firmly against table or
another support device.
MINIMUM STOCK DIMENSION. Small workpieces
can be aggressively pulled from your hands,
causing contact with sanding surface. Always
use a jig or other holding device when sanding
small workpieces, and keep hands and fingers
at least 2" away from sanding surface.

Model W1843 (For Machines Mfd. Since 3/17)
ELECTRICAL
Additional.Safety.for.Buffing.Systems
Serious injury or death can occur from fingers, clothing, jewelry, or hair getting entangled in rotat-
ing buffing wheel, spindle, or other moving components. Workpieces thrown by buffing surface can
strike operator or bystanders with moderate force, causing impact injuries. Long-term respiratory
damage can occur from using machine without proper use of a respirator. To reduce the risk of
these hazards, operator or bystanders MUST completely heed the hazards and warnings below.
HAND/WHEEL CONTACT. Never purposely touch
moving buffing wheel or shaft. Take care to
keep fingers away from buffing wheel during
operations. If the workpiece is small or dif-
ficult to hold, use a workpiece holding fixture.
Abrasives can quickly remove large amounts
of skin!
BE AWARE OF DUST ALLERGIES. Be aware that
certain woods may cause an allergic reaction
in people and animals, especially when fine
dust is created by buffing. Make sure you know
what type of wood dust you will be exposed
to in case there is a possibility of an allergic
reaction.
AVOID KICKBACK. Avoid kickback by buffing in
accordance with directional arrows. Always
buff on the downward side of the wheel—pay
close attention to the direction of wheel rota-
tion to avoid placing the workpiece against the
upward side of the buffing wheel. Avoid buff-
ing with excessive force.
WORKPIECE SELECTION. Always inspect the con-
dition of your workpiece. DO NOT buff pieces
with loose knots, large splinters, protruding
nails, or other objects with sharp edges. DO
NOT buff cable, chain, or other irregularly
shaped objects that may be grabbed by the
buffing wheel and thrown at the operator.
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 buff
workpiece on the top or sides of the buffing
wheel. 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 oper-
ator's hands, causing serious personal injury.
WORKPIECE CONTROL. If you cannot hold small
workpieces securely, do not buff them with
this machine. Hold them with clamps or similar
jigs, or use a smaller buffer.
DISCONNECT POWER WHEN SERVICING.
Disconnect the machine from power and
allow the wheel to come to a complete stop
before service, maintenance, or adjustments.
Avoid pulling cord-connected machinery
from the cord—instead, grasp the plug when
disconnecting it from power.
AVOID ENTANGLEMENT. Tie back long hair and
remove any loose-fitting clothing or jewelry
that could be caught up in the buffing wheel
or other moving machine parts. Avoid wearing
gloves as they may get caught in the buffing
wheel and cause entanglement injuries.
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.
CORRECT ACCESSORIES AND USE. Never install
a grinding wheel on this buffer. It is only
designed for buffing and polishing. Never
exceed maximum speed listed on each buff-
ing/polishing wheel.
OPERATOR POSITION.
Do not stand directly in
front of the buffer wheel when turning the
machine on, or when buffing. Do not buff
material from the rear of the machine.
AVOID WORKPIECE GRAB.
Firmly support the
workpiece against the rotation direction of the
buffing wheel. Otherwise, the buffing wheel
could grab the workpiece and pull your hands
into the moving wheel.

ELECTRICAL
Circuit.Requirements
This machine must be connected to the correct size and
type of power supply circuit, or fire or electrical damage
may occur. Read through this section to determine if an
adequate power supply circuit is available. If a correct
circuit is not available, a qualified electrician MUST install
one before you can connect the machine to power.
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.)
Circuit.Requirements.for.110V
This machine is prewired to operate on a power supply
circuit that has a verified ground and meets the following
requirements:
Circuit.Type................ 110V/120V,.60.Hz,.Single-Phase

ELECTRICAL
Grounding.Requirements
This machine MUST be grounded. In the event of certain
types of
malfunctions or breakdowns, grounding provides
a path of least resistance for electric current
to travel—in
order
to reduce the risk of electric shock.
Improper connection of the equipment-grounding
wire
will
increase
the risk of electric shock. The wire with green
insulation
(with/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.

Extension.Cords
We do not recommend using an extension cord with
this machine. Extension cords cause voltage drop, which
may damage electrical components and shorten motor
life. Voltage drop increases with longer extension cords
and smaller gauge sizes (higher gauge numbers indicate
smaller sizes).
Any extension cord used with this machine must contain a
ground wire, match the required
plug and receptacle, and
meet the following requirements:
Minimum.Gauge.Size.at.110V....................... 14.AWG
Maximum.Length.(Shorter.is.Better).................50.ft.
For.110V.Connection.
This machine is equipped with a power cord with an

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
preventative, but the following steps work well
in a wide variety of situations. Always follow the
manufacturer’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:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it
soak for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/
degreaser 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.
4.
Repeat Steps.2–3 as necessary until clean,
then coat all unpainted surfaces with a
quality metal protectant to prevent rust.

Another option is a “Direct Mount” (see example) where
the machine is secured directly to the workbench with lag
screws and washers.
The base of this machine has mounting holes that allow it
to be fastened to a workbench or other mounting surface
to prevent it from moving during operation and causing
accidental injury or damage.
The strongest mounting option is a “Through Mount” (see
example) where holes are drilled all the way through the
workbench—and hex bolts, washers, and hex nuts are
used to secure the machine in place.

SETUP
Assembly
Before beginning the assembly process, refer to Items.
Needed.for.Setup
and gather everything you need.
Ensure all parts have been properly cleaned of the
heavy-duty rust-preventative applied at the factory, if
applicable. Be sure to complete all steps in the assembly
procedure prior to performing the Test.Run.
To.assemble.machine,.do.these.steps:
1... Slide the mounting adapter onto the right-hand arbor
of the motor assembly with the countersunk holes
facing out, then rotate it so that the flat edge is at
the 10 o'clock position, as shown in Figure 7.
2. Secure the adapter to the motor assembly with (3)
1
⁄4"-20 x
1
⁄2" cap screws (see Figure 7).
3. Back out the (3) cap screws and (4) set screws
in the pivot arm mounting bracket and the pivot
arm bracket, then slide the pivot arm bracket
onto the pivot arm mounting bracket, as shown in
Figures 8–9.
Note: The pivot arm bracket bushing is shipped with
a lubricating grease coating on its outer surface.
This lubricant will keep the motion of the pivot arm
smooth during operation and reduce the wear on the
metal-to-metal surfaces.
4. For now, finger-tighten the three cap screws enough
to hold the two brackets together. You will fully
tighten these fasteners in a later step.
Note: Make sure the four set screws DO NOT make
contact with the opposite bracket.

5. Slide the assembled arm brackets onto the right-
hand arbor with the arm bracket bushing facing
out, as shown in Figure 10, then secure it with the
remaining (3)
1
⁄4"-20 x
1
⁄2" cap screws.
6. Move the machine to the selected mounting surface,
and use the eight holes in the base of the motor
assembly and the pivot arm bracket assembly as a
template for drilling the mounting holes.
7. Loosen the three cap screws of the pivot arm
bracket assembly (see Figures 8–9 on Page.17),
then use the mounting hardware you have chosen to
firmly secure the motor assembly and the bracket
assembly in place.
Note: Before fully tightening the mounting
hardware, make sure that the three cap screws and
four set screws of the arm bracket assembly are
loose. This will allow the mounting bracket to lay
flat on the mounting surface.
8. Tighten the four set screws in the pivot arm bracket
assembly (see Figures 8–9.on Page.17) just until you
feel resistance. This will keep the two parts of the
assembly stable during operation.
9. Fully tighten the three cap screws on the pivot arm
bracket assembly.
10. Back out the two set screws in the round end of the
pivot arm, slide the arm onto the bracket bushing so
that the platen bracket cap screws are facing to the
right, as shown in Figure 11, then tighten the set
screws to hold the pivot arm in place.
Note: The pivot arm and bushing are designed so
that the set screws tighten into the grooved surface
of the bushing. This keeps the pivot arm from
sliding off the bushing when using the tilt feature.

General
To complete a typical sanding operation, the operator
does the following:
1. Examines the workpiece to make sure it is suitable
for sanding.
2. Installs the correct sanding belt for the operation
(composition and grit).
3. Turns the drive wheel by hand to make sure the
sanding belt is tracking correctly and is properly
tensioned.
4. Verifies that the platen is centered on the sanding
belt.
5. Adjusts the tool rest to the correct position for the
operation and makes sure that it is no more than
1
⁄16" away from the sanding belt.
6. Connects the machine to power and pulls the ON/
OFF button out to turn it ON.
7. Verifies that the sanding belt is tracking properly and
rotating without interference.
8. Places the workpiece onto the tool rest and slowly
moves it into the sanding belt with the direction of
the belt.
9. Removes the workpiece and pushes the ON/OFF
button in to turn the machine OFF.
The purpose of this overview is to provide the novice
machine operator with a basic understanding of how
the machine is used during operation, so the

Adjusting.Sanding.Belt.Tracking
To ensure safe operation, the sanding belt must stay
centered on the idler and drive wheels while the machine
is ON. This is a trial-and-error process that requires some
patience.
To adjust the sanding belt tracking, do these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Make sure the sanding belt is correctly installed and
tensioned (refer to the Sanding Belt subsection on
Page 23 for detailed instructions).
3. Rotate the drive wheel several times by hand and
watch the sanding belt as it tracks on the idler and
drive wheels.
— If the sanding belt is centered on the idler and
drive wheels, and does not move to one side
or the other after several rotations, no further
adjustments are necessary.
— If the sanding belt moves to one side or the other
while rotating, continue with this procedure.
4. Make a small adjustment to the tracking adjustment
knob, then rotate the drive wheel several times
while observing the sanding belt (see Figure 22).
— If the sanding belt moves to the right, rotate the
adjustment knob clockwise.
— If the sanding belt moves to the left, rotate the
adjustment knob counterclockwise.
5. Repeat Step 4 until the sanding belt stays centered
on the idler and drive wheels after several rotations.
6. To verify the sanding belt tracking, turn the machine
ON and watch the belt tracking.
— If the belt does not wander, then it is tracking
correctly.
— If the belt does wander, very slowly adjust the
tracking adjustment knob until the belt stays
centered on the wheels.

Belt.Sanding
The sanding belt is used to sand wood or metal. We
recommend using aluminum oxide sanding belts for wood
and silicon carbide for metal. Refer to Accessories on
Page 34 for options from Shop Fox.
Always be sure the sanding belt is properly installed,
tensioned, and tracked before connecting the machine to
power (refer to the Sanding Belt subsection on Page 23
for detailed instructions).
Always adjust the tool rest so that it is no more than
1
⁄16" away from the belt. This helps to ensure that the
workpiece does not get trapped between the rest and the
belt.
Make sure the platen is centered on the sanding belt.
Adjust the platen by loosening both cap screws securing
platen to the vertical rod, then re-tighten the cap screws.
Note: The platen provides a solid back rest and helps
reduce friction as the belt passes the tool rest. Platen
should be lightly touching backside of belt, but not
bowing belt outward.
Figure 23 shows a typical wood sanding operation with
the tool rest perpendicular to the belt surface.
The sanding belt is also used for knife grinding and
sharpening. Figure 24 depicts a typical knife edge
grinding operation. Generally, this is done with the tool
rest removed.
Note: There are many different techniques for using the
sanding belt to grind and sharpen knives. Whichever one
you use, make sure that you hold the knife firmly and
ease it into the belt without excessive pressure to ensure
a safe operation.
The belt is also used for contour sanding. When doing this
type of operation, it is best to remove the platen and the
tool rest so the belt can flex to better conform to the
shape of the workpiece (see Figure 25).

OPERATIONS
The sanding arm assembly tilts to a horizontal position, as
shown in Figure 27. This arrangement is more convenient
for certain types of sanding or grinding operations.
To position the sanding arm assembly horizontally, do
these steps:
1. DISCONNECT MACHINE FROM POWER!
2. While holding the arm assembly, loosen the two
set screws in the round end of the pivot arm

that is correct for your operation.
Note: If you will be using the contour of the drive
wheel for sanding or grinding, remove the tool
rest assembly so that it will not interfere with the
operation. Otherwise, you will need to mount it
differently so that it will not interfere with the
sanding belt.

firs t!
The Model W1843 is capable of both buffing and sanding
operations. IT IS NOT A GRINDER. The absence of grinding
wheel guards and eye shields prohibits the use of this
machine as a grinder.
Note: Use caution when polishing plated metals; there is
a chance that the thin plated material may be damaged.
A light pressure is all that is needed for quality work.

To buff or polish, do these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Remove the arbor nut at the end of the shaft.
3. Insert a buffing wheel (not included) between the
provided wheel flanges. Secure flanges with the
arbor nut removed in the previous step, as shown in
Figure 28.
4. Put on safety glasses and a respirator, then connect
machine to power.
5. Stand to the side of the buffer and turn it ON.
6. Allow the buffer to reach full speed.
7. Select the appropriate stick of polishing compound
for your application, and apply to the rotating face
of the wheel.
8. Once compound is thoroughly applied, firmly grasp
the workpiece with both hands and lightly and
evenly move the workpiece back and forth on the
buffing wheel.

OPERATIONS
Below are some quick tips for getting the most out of your
buffer. Remember, there is no substitute for experience.
Learning how to hold the workpiece, how much pressure
to apply, how to move the workpiece against the wheel,
and how much compound to use requires trial and error.
• Thoroughly clean all parts that you plan to buff.
Dirt, oil, rust, paint or other film must be removed
chemically or with water. Dry parts with a rag.
• Apply buffing compounds in small amounts at a time.
Apply paste-type compounds with a wand or directly
to the part. For wax-based polishing stick-type
compounds, press the compound on the wheel for
a couple of seconds while the machine is running.
Avoid using too much compound.
Buffing
• Put your workpiece under the wheel when you
are loading the compound on the buffing wheel.
This way, you will catch any compound that would
normally be wasted on the floor.
• Only use the area indicated in Figure 29 to do the
actual buffing. Contacting the workpiece on areas
outside the correct area may flip the workpiece out
of your hands.
• Hold the workpiece tightly at all times while buffing.
Placing one hand near the contact point will give you
better control.
• Keep buffing wheels raked out before each use and
when buildup gets heavy during use. Raking means
to clean the buffing wheels with a wheel rake to
remove built-up compounds and metal particles.
ALWAYS use light pressure when raking wheels!
• Do not mix two different compounds on the same
wheel. For best results, use a separate wheel for
each compound.
• Always use an upward stroke with heavy to moderate
pressure for cutting. Use a downward stroke with
light pressure for polishing. See Figure 30.
• Wear safety equipment when buffing. If the buffer
forces the 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 the wheel.

Buffing.Compound.
Selection
Most colors of abrasives have similar applications, but
always check with the manufacturer of your particular
compound.
Shop Fox offers the following compounds:
Red Rouge — Made for fine polishing on brass and gold.
Provides an excellent shine when used with the loose
muslin buffing wheel.
Green (Extra Fine) — Great for extra-fine polishing on
most metals to bring out that mirror finish. Works best
with loose muslin and spiral-sewn buffing wheels.
White — Great for ivory, plastic and resins when used
successively with the soft spiral sewn and soft airway
buffing wheels.
Black — Designed to be used with sisal and airway hard
buffing wheels, this compound is perfect for the initial
rough cut on stainless steel and iron.
Tripoli — A true middle-of-the-road abrasive, Tripoli pro-
vides an excellent medium cut for brass, aluminum and
zinc alloy.
Green (Fine) — Slightly more abrasive than the extra
fine green, this green compound is great for a medium to
fine polish with most softer metals.
