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.

-8-

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.

Model G0458ZX (Mfd. Since 04/24)

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.

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,

Place this machine near an existing power source.

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.
Attempts to 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-

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.

⁄4 turn

Conveyor

Feed Rate Dial

Figure 20. Location of 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.

Model G0458ZX (Mfd. Since 04/24)

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.

Grit Class Usage

60 Coarse Fast sanding, dimen-

sioning, and glue
removal.

80 –100 Medium Removing planer

marks and initial finish
sanding.

120–18 0 Fine Finish 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.

Lubrication

The bearings on the Model G0458ZX have been
lubricated at the factory. No other care is needed
unless they need replacement.

The conveyor belt bushings should be lubricated
daily while the elevation leadscrew, sprockets,
and helical gear should be lubricated periodically,
depending on usage. See Page 27 for some
lubrication products that Grizzly offers.

Avoid using excess lubrication. Too much lubricant
attracts sawdust and will clog the drive bushings.

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.

10. Repeat Steps 7–8.

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

⁄8" long).

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 [phone].
