Safety Instructions for Power Tools
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi-
tion. Conductor size should be in accor-
dance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause
a drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace exten-
sion cords if they become damaged.
15. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom-
mended accessories. The use of improper
accessories may cause risk of injury.
16. REDUCE THE RISK OF UNINTENTION-
AL STARTING. On machines with magnet-
ic contact starting switches there is a risk of
starting if the machine is bumped or jarred.
Always disconnect from power source
before adjusting or servicing. Make sure
switch is in OFF position before reconnecting.
Minimum Gauge for Extension Cords
17. CHECK DAMAGED PARTS. Before fur-
ther use of the tool, a guard or other part
that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended function.
Check for alignment of moving parts, bind-
ing of moving parts, breakage of parts,
mounting, and any other conditions that
may affect its operation. A guard or other
part that is damaged should be properly
repaired or replaced.

In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric cur-
rent. This tool is equipped with a power cord that
has an equipment-grounding prong. The outlet
must be properly installed and grounded in accor-
dance with all local codes and ordinances.
110V Operation
If you find it necessary to use an extension cord
at 110V:
•
•
•
•
Make sure the cord is rated Standard Service
(grade S) or better.
The extension cord must also contain a
ground wire and plug pin.
Electrocution or a fire can
result if the machine is
not grounded correctly.
Make sure all electrical
circuits are grounded. DO
NOT use ungrounded
machines.
Use at least a 16 gauge cord if the cord is 50
feet long or less.
DO NOT use a cord longer that 100 feet!
No single list of electrical guidelines can
be comprehensive for all shop environ-
ments. Operating this machinery may
require additional electrical upgrades spe-
cific to your machine and shop environ-
ment. It is your responsibility to make sure
your electrical systems comply with all
local electrical codes and ordinances.
This machine must have a ground prong in
the plug to help ensure that it is grounded.
DO NOT remove ground prong from plug to
fit into a two-pronged outlet! If the plug will
not fit the outlet, have the proper outlet
installed by a qualified electrician.

Lighting And Outlets
Site Considerations
Lighting should be bright enough to eliminate
shadow and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
the amperage draw. Outlets should be located
near each machine so power or extension cords
are clear of high-traffic areas. Observe local elec-
trical codes for proper installation of new lighting,
outlets, or circuits.
Weight Load
The Model G7297 Disc Sander is a small weight
load with a small footprint. Most shop floors and
workbenches should be sufficient to carry the
weight of the machine. Reinforce the floor and
workbench if you question its ability to support the
weight.
Working Clearance
Unsupervised
and visitors inside your
shop could receive seri-
children
Working clearances can be thought of as the dis-
tances between machines and obstacles that
allow safe operation of every machine without
limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands or work tables. Also consider the relative
position of each machine to one another for effi-
cient material handling.

Ensure child and visitor
safety by keeping all
entrances to the shop
locked at all times. DO
NOT allow unsupervised
children or visitors in the
shop at any time.

Miter Gauge
Attaching Sandpaper
The Model G7297 Disc Sander accepts 12" diam-
eter cloth or paper-backed PSA sanding discs.
These are available in a variety of grits. See the
current Grizzly catalog for prices and ordering
information.
The miter gauge needs to be adjusted perpendic-
ular to the face of the wheel when it is mounted in
the table slot.
To adjust miter gauge:
The sanding disc sticks to the surface of the cast
iron disc, using the pressure sensitive adhesive
backing (PSA) on the reverse side of the sand-
paper disc. The sandpaper can be replaced with-
out removing either the table or the dust port.
1. Use a try square or machinist’s square with
one edge against the face of the miter gauge
and the other against the disc face as shown
in Figure 4.
2. Loosen the adjusting screw on the miter
gauge and adjust it flush with the edge of the
square.
To attach sandpaper:
1. Peel back the protective layer on one-half of
the sandpaper disc and fold it against the
remaining half.
3. Tighten the gauge adjusting screw, and veri-
fy the setting. Note—Sometimes the tighten-
ing procedure can affect the adjustment.
2. Slip the half with the protective layer
between the disc and the table edge (Figure
5).
4. Loosen the screw that secures the angle
pointer and adjust the pointer to the 0˚ mark.
5. Retighten the screw that secures the angle
pointer.

3. Position the exposed adhesive on the upper
half of the disc that extends above the table.
Once it is positioned evenly across the disc,
press the adhesive onto the surface.
Aligning Table
The table must be aligned to the face of the sand-
ing disc so that the sandpaper does not rub
against the table.
4. Now rotate the disc so the lower half is now
above the table.
To align the table:
5. Bend the paper back and remove the
remaining half of the protective layer (Figure
6), and then press this portion against the
disc.
1. Loosen the screws that secure the table to
the table support bracket.

2. Align the table so that there is a ⁄16'' gap
between the 12" disc and the table (Figure
7).
3. Tighten the screws loosened in step 1.
4. Spin the disc by hand to check if the sand-
paper is touching the table. Note—DO NOT
turn the disc sander on at this point.
5. Repeat steps 1-3 if sandpaper touches table
at any point in the rotation.

SECTION 7: OPERATIONS
Disc Sanding
General
This section will cover basic disc sanding opera-
tions. Please read the remaining portion of the
manual before attempting any type of operation.
To perform sanding operations:
1. Set the angle of the table relative to the
sanding disc. The angle can be set with the
angle gauge on the disc sander or with a pro-
tractor for greater accuracy.
Your safety is important! Please follow the
warnings below during this entire section:
2. When a 90˚ horizontal angle is required,
place one surface of the workpiece firmly
against the face of the miter gauge (set at
0˚), with the other surface against the face of
the disc (Figure 8).
Damage to your eyes, lungs, and ears
could result from failure to wear safety
glasses, a dust mask, and hearing protec-
tion while sanding with this machine.
Note—For sanding curves or irregular shapes,
remove the miter gauge from the disc table.
Always keep the workpiece on the side of the
wheel that is rotating down toward the table. This
will keep the workpiece from flying out of your
hands from the rotational forces.
Loose hair and clothing
could get caught in
machinery and cause
serious personal injury.
Keep loose clothing
rolled up and long hair
tied up and away from
machinery.
Figure 8. Disc sanding.
Operating this equipment has the potential
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).

Miter Sanding
Angle Sanding
The most efficient way to get a perfect miter is to
cut the workpiece slightly long and sand it to the
desired dimension. Miter sanding can be done
easily with the miter gauge:
To perform angle sanding operations:
1. Loosen the handles securing the table.
2. Use the angle gauge to acheive the desired
table angle and tighten the handles. Note—
The disc table can be positioned from -15˚ to
35˚, relative to the plane of the sanding sur-
face. Whenever possible, sand with an open
angle where there is plenty of clearance
between the disc and the table. This will
avoid trapping the workpiece between the
sanding surface and the table.
To perform miter sanding operations:
1. Loosen the knob on the miter gauge and
adjust the angle to the desired point. Tighten
the knob.
2. Slide the miter gauge into its slot and use it
to hold your workpiece in position. Note—
The miter gauge can be used in either direc-
tion in the slot to achieve the proper relation
of the workpiece to the disc.
3. Slide the miter gauge into its slot and use it
to hold your workpiece in position.
3. With light, but firm pressure, push the work-
piece slowly into the downspin side of the
rotating disc (Figure 9).
4. With light, but firm pressure, push the work-
piece slowly into the downspin side of the
rotating disc (Figure 10).
