An oscillating spindle sander is used to sand
the edges of contoured or irregularly shaped
workpieces.
The Model G9922 Oscillating Spindle Sander
uses 2" x 51⁄4" sanding sleeves and oscillates with
a 1" stroke at a rate of 64 strokes per minute.
The 141⁄2" square sanding table provides a solid
platform for supporting workpieces and can tilt up
to 45° for sanding beveled edges. The table also
features a miter gauge for sanding straight edges
on a miter-cut workpiece.
The integrated 2" dust collection port can be fitted
to a dust collection system to reduce the amount
of dust released by the machine.
During typical operation, the table is tilted to the
desired angle and locked in place with the lock
knobs. The machine is turned on and the spindle
is allowed to reach its full speed. With steady pres-
sure against both the table and the sanding drum,
the workpiece is fed past the drum. The amount
of material removed depends on the speed and
pressure with which the workpiece is fed and the
grit of the sanding sleeve.
Sanding sleeves are replaced by un-threading the
plastic cap and sliding the sleeve off the drum.

7. ONLY ALLOW TRAINED AND PROP-
ERLY SUPERVISED PERSONNEL TO
OPERATE MACHINERY. Make sure
operation instructions are safe and clearly
understood.
8. KEEP CHILDREN/VISITORS AWAY.
Keep all children and visitors away from
machinery. When machine is not in use,
disconnect it from power, lock it out, or
disable the switch to make it difficult for
unauthorized people to start the machine.
9. UNATTENDED OPERATION. Leaving
machine unattended while its running
greatly increases the risk of an accident or
property damage. Turn machine Off and
allow all moving parts to come to a com-
plete stop before walking away.
10. DO NOT USE IN DANGEROUS
ENVIRONMENTS. DO NOT use machin-
ery in damp, wet locations, or where any
flammable or noxious fumes may exist.
11. KEEP WORK AREA CLEAN AND WELL
LIGHTED. Clutter and dark shadows may
cause accidents.
12. USE A GROUNDED POWER SUPPLY
RATED FOR THE MACHINE AMPERAGE.
Grounded cords minimize shock hazards.
Operating machine on an incorrect size of
circuit increases risk of fire.
13.
ALWAYS DISCONNECT FROM POWER
SOURCE BEFORE SERVICING
MACHINERY. Make sure switch is in
OFF
position before reconnecting.
14. MAINTAIN MACHINERY WITH CARE.
Keep blades sharp and clean for best and

Safety Instructions for Machinery
16. REMOVE CHUCK KEYS OR ADJUSTING
TOOLS. Make a habit of never leaving
chuck keys or other adjustment tools in/on
the machine—especially near spindles!
17. DAMAGED MACHINERY. Check for bind-
ing or misaligned parts, broken parts,
loose bolts, other conditions that may
impair machine operation. Always repair or
replace damaged parts before operation.
18. DO NOT FORCE MACHINERY. Work at
the speed for which the machine or acces-
sory was designed.
19. SECURE WORKPIECE. Use clamps or
a vise to hold the workpiece when practi-
cal. A secured workpiece protects your
hands and frees both hands to operate the
machine.
20. DO NOT OVERREACH. Maintain stability
and balance at all times when operating
machine.
21. MANY MACHINES CAN EJECT
WORKPIECES TOWARD OPERATOR.
Know and avoid conditions that cause the
workpiece to "kickback."
22. STABLE MACHINE. Machines that move
during operations greatly increase the
risk of injury and loss of control. Verify
machines are stable/secure and mobile
bases (if used) are locked before starting.
23. CERTAIN DUST MAY BE HAzARDOUS
to the respiratory systems of people and
animals, especially fine dust. Be aware of
the type of dust you are exposed to and
always wear a respirator designed to filter
that type of dust.
24. EXPERIENCING DIFFICULTIES. If at
any time you are experiencing difficulties
performing the intended operation, stop
using the machine! Contact our Technical
Support Department at [phone].

Additional Safety Instructions For
Spindle Sanders
1. BE AWARE OF SPINDLE rotation when
sanding.
2. KEEP FINGERTIPS AWAY from the mov-
ing spindle. Serious injury could result if
skin contacts abrasives or moving parts.
3. NEVER USE EXCESSIVE FORCE when
sanding. Doing this greatly increases the
chances of personal injury and motor over-
load.
4. ALWAYS FEED THE WORK against the
direction of rotation.
5. EVEN IF YOU HAVE A RELIABLE
METHOD OF DUST COLLECTION, use a
dust mask or respirator when sanding, as
well as eye and ear protection.
6. IF THERE IS ANY doubt as to the stability
or integrity of the material to be sanded,
don’t sand it.
7. DO NOT OPERATE SANDER with a dam-
aged or badly worn sanding sleeve.
8. TIE BACK LONG HAIR and remove any
loose-fitting clothing or jewelry that could be
caught up in the sander’s spindle or other
moving machine parts.
9. HABITS — GOOD OR BAD — are hard to
break. Develop good habits and safety will
become second nature to you.
Like all power tools, there is danger asso-
ciated with the Model G9922 Oscillating
Spindle Sander. Accidents are frequently
caused by lack of familiarity or failure to
pay attention. Use this tool with respect and
caution to lessen the possibility of opera-
tor injury. If normal safety precautions are
overlooked or ignored, serious personal
injury may occur.
No list of safety guidelines can be com-
plete. 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 follow guidelines could
result in serious personal injury, damage to
equipment or poor work results.
Operation of this equipment has the poten-
tial to propel debris into the air which can
cause eye injury. Always wear safety glass-
es or goggles when operating equipment.
Everyday glasses or reading glasses only
have impact resistant lenses, they are not
safety glasses. Be certain the safety glass-
es you wear meet the appropriate stan-
dards of the American National Standards
Institute (ANSI).

Floor Load
Refer to the Machine Data Sheet for the weight
and footprint specifications of your machine.
Some residential floors may require additional
reinforcement to support both the machine and
operator.
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 machine. See Figure 6 for the minimum
working clearances.
Children and visitors may be
seriously injured if unsuper-
vised around this machine.
Lock entrances to the shop
or disable start switch or
power connection to prevent
unsupervised use.
Site Considerations
Figure 6. Minimum working clearances.
The unpainted surfaces are coated with a waxy
oil to prevent corrosion during shipment. Remove
this protective coating with a solvent cleaner or
degreaser, such as shown in Figure 5. For thor-
ough cleaning, some parts must be removed. For
optimum performance from your machine,
clean all moving parts or sliding contact sur-
faces. Avoid chlorine-based solvents, such as
acetone or brake parts cleaner that may damage
painted surfaces. Always follow the manufactur-
er’s instructions when using any type of cleaning
product.
Clean 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.

Although not required, you may choose to mount
your new machine to the floor. Because this is an
optional step and floor materials may vary, floor
mounting hardware is not included. Generally, you
can either bolt your machine to the floor or mount
it on machine mounts. Both options are described
below. Whichever option you choose, it is neces-
sary to level your machine with a precision level.
Bolting to Concrete Floors
Lag shield anchors with lag bolts and anchor
studs (Figure 7) are two popular methods for
anchoring an object to a concrete floor. We sug-
gest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application.
Mounting to Shop
Floor
Figure 8. Machine mount example.
Using Machine Mounts
Using machine mounts, shown in Figure 8, gives
the advantage of fast leveling and vibration reduc-
tion. The large size of the foot pads distributes
the weight of the machine to reduce strain on the
floor.
NOTICE
Anchor studs are stronger and more per-
manent alternatives to lag shield anchors;
however, they will stick out of the floor,
which may cause a tripping hazard if you
decide to move your machine.
Figure 7. Typical fasteners for mounting to
concrete floors.
NOTICE
We strongly recommend securing your
machine to the floor if it is hardwired to the
power source. Consult with your electrician
to ensure compliance with local codes.
