may damage the wires inside. Do not handle
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 material. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing 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 modifications—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.

Additional Safety for Drum Sanders
Serious injury or death can occur from getting hands trapped between workpiece and conveyor
table and being pulled into machine, or becoming entangled in rotating parts inside machine.
Workpieces thrown by sander can strike nearby operator or bystanders with significant force.
Long-term respiratory damage can occur from using sander without proper use of a respirator.
To reduce the risk of these hazards, operator and bystanders MUST completely heed the
hazards and warnings below.
FEEDING WORKPIECE. Placing fingers between
workpiece and conveyor can result in pinching
injuries, or possibly getting trapped and pulled into
sanding area of machine. DO NOT place fingers
under bottom of workpiece while feeding it into
sander.
SANDING DUST. Sanding creates large amounts
of fine airborne dust that can lead to eye injury
or serious respiratory illness. Reduce your risk
by always wearing approved eye and respiratory
protection when sanding. Never operate without
adequate dust collection system in place and running. However, dust collection is not a substitute
for using a respirator.
POWER DISCONNECT. An accidental startup
while changing sanding belts or performing adjustments or maintenance can result in serious entanglement or abrasion injuries. Make sure machine
is turned OFF, disconnected from power and
air, and all moving parts are completely stopped
before changing belts, doing adjustments, or performing maintenance.
SANDPAPER CONTACT. Rotating sandpaper
can remove a large amount of flesh quickly. Keep
hands away from rotating sanding drum(s) during
operation. Never touch moving sandpaper.
AVOIDING ENTANGLEMENT. Tie back long
hair, remove jewelry, and do not wear loose
clothing or gloves. These can easily get caught
in moving parts. Never reach inside machine or
try to clear jammed workpiece while machine is
operating. Keep all guards in place and secure.
WORKPIECE MATERIAL. This sander is
designed to sand only natural wood products
or man-made products made from natural wood
fiber. DO NOT sand any metal products.
WORKPIECE INSPECTION. Nails, staples,
knots, or other imperfections in workpiece can
be dislodged and thrown from sander at high rate
of speed into operator or bystanders, or cause
damage to sandpaper or sander. Never try to
sand stock that has embedded foreign objects or
questionable imperfections.
KICKBACK. Occurs when a workpiece is ejected out the front of sander at a high rate of speed
toward operator or bystanders. To reduce risk
of kickback-related injuries, always stay out of
workpiece path, only feed one board at a time,
and always make sure pressure rollers are properly adjusted below sanding roller. Never sand
workpieces below minimum specifications listed
in Machine Data Sheet.
Like all machines there is danger associated with this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the possibility of operator injury. If normal safety
precautions are overlooked or ignored, serious personal injury may occur.

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
not properly grounded
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:

Grounding & Plug 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!
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. 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:
Two-prong outlets do not meet the
grounding requirements for this machine.

This machine creates a lot of wood chips/
dust during operation. Breathing airborne
dust on a regular basis can result in permanent respiratory illness. Reduce your risk
by wearing a respirator and capturing the
dust with a dust-collection system.
Minimum CFM at Dust Port: 400 CFM
Do not confuse this CFM recommendation with
the rating of the dust collector. To determine the
CFM at the dust port, you must consider these
variables: (1) CFM rating of the dust collector,
(2) hose type and length between the dust collector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines
throughout the system. Explaining how to calculate these variables is beyond the scope of
this manual. Consult an expert or purchase a
good dust collection "how-to" book.
To connect machine to a dust collector:

Stock Inspection &
Requirements
Some workpieces are not safe to sand, or they
may require further preparation before they can
be safely sanded without increasing risk of injury
to the operator or damaging the sandpaper or the
sander.
Before sanding, inspect all workpieces for the
following:
• Material Type: This machine is intended
for sanding natural and man-made wood
products, and laminate-covered wood products. This machine is NOT designed to sand
glass, stone, tile, plastics, drywall, cementious backer board, metal, etc.
Sanding metal objects can increase the risk
of fire. Sanding improper materials increases
the risk of respiratory harm to the operator
and bystanders due to the especially fine
dust inherently created by all types of sanding operations—even if a dust collector is
used. Additionally, the life of the machine
and sandpaper may be greatly reduced (or
immediately damaged) from sanding improper materials.
• Foreign Objects: Nails, staples, dirt, rocks
and other foreign objects are often embedded in wood. While sanding, these objects
can become dislodged and tear the sandpaper. Always visually inspect your workpiece
for these items. If they can't be removed,
DO NOT sand the workpiece.
Setting Depth of Cut
The optimum depth of cut will vary based on
the type of wood, feed rate, and sandpaper grit.
Attemptsto remove too much material can cause
jamming, wood burning, rapid paper wear or tearing, poor finish, and belt slippage.
Generally, a 1⁄4 turn of the drum height handwheel
1
⁄64" or 0.4mm vertical movement) per pass is
(
acceptable for coarser grits or softer woods. A
turn of the handwheel is recommended for finer
grits or harder woods. However, use your best
judgement to produce good sanding results for
your operation.
IMPORTANT: Keep in mind that, although the
thickness of the workpiece is reduced during
sanding, this process is not a replacement for
thickness planing, which should be done with a
planer or other acceptable tool/machine before
beginning the sanding process.
Taking excessive depth of cut could cause
drum motor to exceed available power
source amperage. In this case, motor or
power source circuit breaker will trip. If this
should happen, disconnect machine from
power, allow motor to cool, reset circuit
breaker, then take smaller depth of cut.
1
⁄8
• Wet or "Green" Stock: Sanding wood with
a moisture content over 20% causes unnecessary clogging and wear on the sandpaper,
increases the risk of kickback, and yields
poor results.
• Excessive Warping: Workpieces with
excessive cupping, bowing, or twisting are
dangerous to sand because they are unstable and often unpredictable when being
sanded. DO NOT use workpieces with these
characteristics!
Model G0458ZX (Mfd. Since 04/24)
-21-
Page 24
To set depth of cut:
1. Rotate table elevation handwheel
(see Figure 19) until conveyor table is well
below sanding drum, then raise table, allowing a gap between workpiece and sanding
drum.
Note: When adjusting table to sand a
thicker workpiece, lower and then raise
table to remove backlash from adjustment
mechanism.
Adjusting Conveyor
Feed Rate
The conveyor feed rate dial (see Figure 20)
allows you to adjust the feed rate from 2–12 FPM.
The correct speed to use depends on the type of
stock you are using (hardwood vs. softwood) and
the stage of finish with that workpiece.
Table Elevation
Handwheel
Figure 19. Table elevation handwheel.
2. Turn machine ON and feed workpiece into
sander. SLOWLY raise conveyor belt until
workpiece makes light contact with sanding drum. This is the correct height to begin
sanding the workpiece.

3. After initial pass, turn handwheel up to
1
⁄64" or 0.4mm)—maximum depth for most
(
sanding conditions.
Note:Each full turn of the table elevation
handwheel raises the conveyor table approximately 0.060" (
1
⁄16") or 1.6mm.

Conveyor
Feed Rate Dial

As a general rule, a slower feed rate will sand
the surface smoother, but runs the risk of burning
the wood; a faster feed rate will remove material
faster, but runs the risk of overloading the motor
or damaging the sandpaper.
Use trial-and-error to determine the best settings
for your specific applications.
To adjust feed rate:
1. Turn machine ON.
2. Rotate conveyor feed rate dial (see Figure 20)
clockwise to increase feed rate or counterclockwise to decrease feed rate.

Sanding Tips
• Feed boards into the sander at different places on the conveyor to maximize sandpaper
life and prevent uneven conveyor belt wear.
• DO NOT edge sand boards. This can cause
boards to kickback, causing serious personal
injury. Edge sanding boards also can cause
damage to the conveyor belt and sandpaper.
• DO NOT sand more than one board at a time
side by side. Minor variations in thickness
can cause one board to be propelled by the
rapidly spinning sanding drum and ejected
from the machine.
• NEVER stand directly in front of the infeed
area of the machine. Failure to do so could
result in severe personal injury.
• Overloading the motor or pushing the sander
to failure weakens the electrical system.
Repeatedly doing so is abuse to the machine
that will cause motor, capacitor, or circuit
breaker damage, which is not covered under
warranty.
• DO NOT sand boards less than 6" long or
1
less than
⁄8" thick to prevent damage to the
workpiece and the drum sander.
• Sanding workpieces with high-resin content
or with applied finishes can quickly contaminate sandpaper beyond the point where it can
be properly cleaned. This will produce poor
sanding results. In this case, use a different
workpiece, remove the applied finishes, or
frequently clean/replace the sandpaper strip.
• Extend the life of the sandpaper by regu-
®
larly using a PRO-STIK
sanding pad (see
Page 28).
• Run wide stock through two or three times
without adjusting table height. Turn stock
180° between passes to ensure an evenly
sanded surface.
• When sanding workpieces with irregular
surfaces, such as cabinet doors, take very
light sanding passes to prevent gouges.
When the drum moves from sanding a wide
surface to sanding a narrow surface, the load
on the motor will be reduced, and the drum
will speed up, causing a gouge.
• When sanding workpieces with a bow or
crown, place the high point up or cupped side
down to prevent the workpiece from rocking
and take very light passes.
• Feed the workpiece at an angle to maximize stock removal and sandpaper effectiveness, but feed the workpiece straight to
reduce sandpaper grit scratches for the finish
passes.
• Replace coarse grit sandpaper with a finer
grit to achieve a smoother finish.
1
• Raise the conveyor a maximum of
⁄4 turn
of the handwheel until the workpiece is the
desired thickness.
• Reduce snipe when sanding more than one
board of the same thickness by feeding them
into the sander with the front end of the second board touching the back end of the first
board.

Choosing Sandpaper
To replace sandpaper:
1. DISCONNECT MACHINE FROM POWER!
There are many types of sandpaper to choose
from. We recommend aluminum oxide for general
workshop environments. Below is a chart that
groups abrasives into different classes, and shows
which grits fall into each class.
GritClassUsage
60CoarseFast sanding, dimen-
sioning, and glue
removal.
80 –100MediumRemoving planer
marks and initial finish
sanding.
120–18 0FineFinish sanding.
The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50. Avoid skipping
grits; the larger the grit increase, the harder it will
be to remove the scratches from the previous grit.
2. Remove cap screw and flat washer (see
Figure 21), then open top cover.
Figure 21. Location of top cover cap screw.
3. Remove chip deflector plate.
Ultimately, the type of wood you use and your
stage of finish will determine the best grit types to
install on your sander.

Tensioning V-Belt
Proper tension is important for optimum power
transmission. However, too much tension may
cause premature bearing failure.
Belt and pulley will be hot after operation.
Allow them to cool before handling.
To tension V-belt:
Correct V-belt tension is achieved when the
V-belts can be deflected
in the middle with moderate pressure. Refer to
Figure 37 for an example of how to perform a
V-belt deflection test with a straightedge and ruler.

Figure 37. Checking V-belt tension.
Always inspect V-belt for damage or deterioration when adjusting for tension. Should
you find evidence of cracking, abrasion or
damage from wood chips or other foreign
materials, replace the belt immediately. Belt
breakage may lead to mechanical damage
or operator injury.
Figure 38. V-belt components.
4. Tension V-belt by pushing down on bottom
motor pulley with one hand, tighten motor
mount cap screws, then check belt tension.
5. Repeat Steps 3–4 as needed until V-belt is
correctly tensioned, then install belt access
panel.
NOTICE
New V-belts will often stretch and loosen
after approximately 16 hours of use. Check
frequently after installation and re-tension
if necessary.

Replacing V-Belt
A worn/damaged V-belt will not provide optimum
power transmission from the motor to the drum
belt. Inspect the V-belt closely; if you notice
fraying, cracking, glazing, or any other damage,
replace the belt.
V-belt removal and replacement is simply a matter
of loosening the V-belt, rolling it off of the pulleys,
replacing it with a new belt, then re-tensioning.

Speed on Page 26).
6. Properly tension V-belt (see Tensioning
V-Belt on Page 33 for more information).
7. Close belt access panel.
Aligning Pulleys
Pulley alignment is an important factor in power
transmission and belt life. The pulleys should
be parallel to each other and in the same plane
(coplaner) for optimum performance.
To replace V-belt:
1. DISCONNECT MACHINE FROM POWER!
2. Open belt access panel.
3. Loosen motor mount cap screws shown in
Figure 39.
4. Lift motor pulley to de-tension belt, and tighten

Tracking & Tensioning
Conveyor Belt
The conveyor belt tension and tracking adjustments are controlled by the adjustment screws
located at end of the front conveyor roller. If the
conveyor is too loose or tracks to one side, it must
be adjusted.
Working around moving conveyor and parts
presents pinch/entanglement hazards that
can cause personal injury. Use extreme
care to keep hands clear of in-running
pinch points while adjusting tracking when
machine is running. Roll up sleeves and do
not wear gloves or other apparel that could
become entangled in moving parts.
To track & tension conveyor belt:
1. Use permanent marker, paper correction
fluid, or fingernail polish to make a reference
mark on roller bracket and fixed plate (see
Figure 41). This reference point will provide
a visual aid in keeping track of adjustments.

Making Gauge Blocks
The blocks described below will be required to
complete the alignment procedures in the following sub-sections.
Tabl e Sa w .......................................................... 1
Aligning Table to
Sanding Drum
Making sure the conveyor table is aligned parallel
to the sanding drum (see Figure 46) is critical for
sanding accuracy. Care should be taken to make
the tolerances as close as possible within about
0.5mm from one side to the other when adjusting
the conveyor table.
To make gauge blocks:
1. Edge joint concave edge of 2x4 flat on jointer, as shown in Figure 47.
Figure 47. Edge jointing on jointer.
2. Place jointed edge of 2x4 against table saw
fence and rip cut just enough off opposite
side to square up two edges of 2x4, as shown
in Figure 48.

5. Starting at board A (see Figure 49), find larg-
est size feeler gauge that can pass between
drum and gauge block. (Feeler gauge should
slide with moderate resistance, without forcing drum to roll.
6. Repeat Step 5 at board B.
— If difference between A and B is 0.020" or
less, then no adjustment is necessary.

8. Rotate both table adjustment knobs
⁄4 turn at
a time and repeat Steps 3–4 between each
adjustment until drum touches gauge evenly
on both sides.
Tip: Place shop rag over adjustment knob
and use slip-lock pliers to rotate.
— If difference between A and B is more than
0.020", then one end must be adjusted to
within 0.020" of other. Proceed to Step 7.
Model G0458ZX (Mfd. Since 04/24)
— Rotate adjustment knob clockwise to raise
table and counterclockwise to lower.
IMPORTANT: Rotate table front and rear
adjustment knob equally to ensure table
remains even from front-to-back.
9. Tighten all adjustment knob set screws and
both cap screws, then recheck.
10. Install sandpaper (see Replacing Sandpaper
beginning on Page 24).
11. Close and secure top cover.

Aligning Pressure
Rollers
Two spring-loaded pressure rollers help maintain
consistent pressure on the workpiece as it passes
the sanding drum. The pressure rollers have been
set correctly at the factory. DO NOT adjust the
pressure rollers unless absolutely necessary.
4. Place gauge block under outside end of
sanding drum along edge of conveyor belt
(see Figure 52).
Sanding
Drum
When properly positioned, the pressure rollers
should be approximately 0.004" lower then the
sanding drum.
Adjusting the pressure rollers is a fine balance
between too much pressure and not enough. Too
much pressure can cause problems like snipe
or overloading the motor. Not enough pressure
may allow the workpiece to kick out of the sander
toward the operator.
Gauge Block 2" x 4" x 36" (see Page 38) ......... 1
To align pressure rollers:
1. DISCONNECT MACHINE FROM POWER!
2. Ensure table is properly aligned with sanding drum (refer to Aligning Table to Sanding
Drum beginning on Page 38).
3. Open cover and remove chip deflector plate
(see Figure 51).

11. Install chip deflector plate, then close and
secure top cover.
The conveyor belt is driven by a universal motor
that uses two carbon brushes to transmit electrical current inside the motor. These brushes
are considered to be a regular "wear item" or
"consumable" that will need to be replaced during
the life of the motor. The frequency of required
replacement is often related to how much the
motor is used and how hard it is pushed.
Replace both carbon brushes as a set when the
motor no longer reaches full power, or when the
brushes measure less than
5
