Additional Safety Instructions for
Belt and Disc Sanders
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.
Like all machinery, there is potential danger
when operating this sander. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this sander
with respect and caution to lessen the
possibility of operator injury. If normal safety
precautions are overlooked or ignored,
serious personal injury may occur.
1. RESPIRATOR AND SAFETY GLASSES.
Always wear a respirator and safety glasses
while operating the sander. Dust and chips
are created when sanding. Some debris will
be ejected, becoming hazards to the eyes
and lungs.
2. AVOIDING ENTANGLEMENT. DO NOT
wear loose clothing articles, gloves, or
jewelry while operating this machine. Button
long sleeves and tie back long hair.
3. HAND PROTECTION. DO NOT place hands
near, or in contact with, sanding belt/disc
during operation. DO NOT allow fingers to
get pinched between the workpiece and
sanding table. This may pull the operator's
hand into the machine and cause serious
injury.
4. INSPECTING WORKPIECES. Always
inspect workpiece for nails, staples, knots,
and other objects that could be dislodged
and thrown from the machine during sanding
operations.
5. REPLACING SANDPAPER. Replace
sanding paper when it becomes worn or
torn. DO NOT operate the sander with
damaged or badly worn sandpaper.
6. UNATTENDED OPERATION. Never leave
the machine running attended.
7. DUST COLLECTION SYSTEM. Always
operate the sander with an adequate dust
collection system in place and running.
8. FEEDING STOCK. Firmly grasp the
workpiece in both hands and ease it into
the sandpaper with light pressure. DO NOT
jam the workpiece into the machine during
operations. Feed the workpiece against
the direction of sandpaper travel. DO NOT
sand tapered or pointed stock with the point
facing the direction of sandpaper travel.
Never sand more than one piece of stock at
a time.
9. MAINTENANCE AND ADJUSTMENTS.
Perform machine inspections and
maintenance service promptly when called
for. Disconnect power before performing
maintenance or adjustments on the sander,
with the exception of sanding belt tracking.

Placement Location
Consider existing and anticipated needs, size of
material to be processed through each machine,
and space for auxiliary stands, work tables or
other machinery when establishing a location for
your new combo sander.
We recommend placing the machine at the corner
of a benchtop so that both the sanding belt and
disc can be accessed without having to move the
sander.
See Figure 5 for the minimum working
clearances.
Children and visitors may
be seriously injured if
unsupervised around this
machine. Lock entrances
to the shop or disable start
switch or power connection
to prevent unsupervised
use.
The unpainted surfaces are coated with a waxy
oil to prevent corrosion during shipment. Remove
this protective coating with a solvent cleaner or
citrus-based degreaser such as Grizzly’s G7895
Citrus Degreaser. To clean thoroughly, some parts
must be removed. For optimum performance
from your machine, clean all moving parts or
sliding contact surfaces. Avoid chlorine-based
solvents, such as acetone or brake parts cleaner
that may damage painted surfaces. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Site ConsiderationsClean Up
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. DO
NOT use these products
to clean the machinery.
Many cleaning solvents
are toxic if inhaled.
Minimize your risk by only
using these products in a
well ventilated area.
Figure 1. Grizzly citrus degreaser.
G7895—Grizzly Citrus Degreaser
This natural, citrus-based degreaser is a great
solution for removing export grease, and it’s much
safer to work around than nasty solvents.

Test Run
Once the assembly is complete, test run your
sander to make sure it runs properly and is ready
for regular operation.
The test run consists of verifying the following:
1) The motor powers up and runs correctly, and
2) the switch disabling mechanism on the switch
works correctly.
If, during the test run, you cannot easily locate
the source of an unusual noise or vibration,
stop using the machine immediately, then review
Troubleshooting on Page 24.
If you still cannot remedy a problem, contact our
Tech Support at (570) 546-9663 for assistance.
To test run the sander:
1. Make sure you have read the safety
instructions at the beginning of the manual
and that the machine is setup properly.
2. Make sure all tools and objects used during
setup are cleared away from the machine.
3. Connect the machine to the power source.
4. Verify that the machine is operating correctly
by turning the machine ON.
—When operating correctly, the machine
runs smoothly with little or no vibration or
rubbing noises.
— Investigate and correct strange or unusual
noises or vibrations before operating the
machine further. Always disconnect the
machine from power when investigating or
correcting potential problems.
7. Flip the toggle switch to the ON position.
—If the machine does not start, the switch
disabling feature is working as designed.
—If the machine starts, immediately stop the
machine. The switch disabling feature is
not working correctly. This safety feature
must work properly before proceeding with
regular operations. Call Tech Support for
help.
8. When the Test Run has been successfully
completed, check the tracking of the sanding
belt and make adjustments if necessary (refer
to Sanding Belt Tracking on Page 22).
Figure 21. Removing disabling key from the
toggle switch.
-18- Model H8192 1" Belt/8" Disc Combo Sander
Mounting Sander
Once you have confirmed that your machine is
running properly, mount it to a workbench.
The strongest mounting option is a "Through
Mount" where holes are drilled all the way through
the workbench, and hex bolts, washers, and
lock nuts are used to secure the sander to the
workbench.
Figure 22. Example of a through mount setup.
Figure 23. Example of a direct mount setup.
Another option for mounting is a "Direct Mount"
where the machine is simply secured to the
workbench with a lag screw.
Dust Collection
To connect a dust collection hose:
1. Fit a 2" dust hose from the dust collection
system over each dust port, and secure them
in place with a 2" hose clamp.
2. Tug the hoses to make sure they do not
come off.
Note: A tight fit is necessary for proper
performance.
DO NOT operate the Model H8192 without
an adequate dust collection system. This
sander creates substantial amounts of wood
dust while operating. Failure to use a dust
collection system can result in short and
long-term respiratory illness.
Recommended CFM at EACH Dust Port:
100 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.
Note: To reduce vibration when operating, keep
the rubber cushion included with your sander
between the machine base and the workbench.
