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 avoid
accidental slips, which could cause loss of workpiece control.
HAZARDOUS DUST. Dust created while using
machinery may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and 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.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
CHECK DAMAGED PARTS. Regularly inspect
machine for any condition that may affect safe
operation. Immediately repair or replace damaged
or mis-adjusted parts before operating machine.
MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.

Additional Safety for Disc Sanders
Serious injury or death can occur from fingers or hands contacting sandpaper, or from fingers,
clothes, or hair getting entangled in sanding disc. Workpieces thrown by sander can strike nearby
operators with great force. Long-term respiratory damage can occur from using sander without a
respirator and adequate dust collection system. To minimize risk of getting hurt or killed, anyone
operating machine MUST completely heed hazards and warnings below.
DISC DIRECTION. Only sand on downward-mov-
ing left side of sanding disc. Sanding on upwardmoving right side of sanding disc forces operator
to rely only on hands (rather than table) for support, which increases risk of workpiece “kick-out”
and impact/abrasion injuries.
HAND PLACEMENT. Rotating sandpaper can
remove a large amount of flesh in a few seconds.
Always keep hands away from sandpaper during
operation. Never touch moving sandpaper on purpose. Use a brush to clean table of sawdust and
chips.
FEEDING WORKPIECE. Forcefully jamming workpiece into sanding surface could cause workpiece
to be aggressively grabbed and pull your hands
into sanding surface. Firmly grasp workpiece in
both hands and ease it into sandpaper using light
pressure.
MINIMUM STOCK DIMENSION. Small workpieces can be aggressively pulled from your hands.
Always use a jig or other holding device when
sanding small workpieces, and keep hands and
fingers at least 2” away from sanding surface.
AVOIDING ENTANGLEMENT. Becoming entangled in moving parts of this machine can cause
pinching and crushing injuries. To avoid these
hazards, DO NOT wear loose clothing, gloves, or
jewelry, and tie back long hair. Keep all guards in
place and secure.
IN-RUNNING NIP POINTS. The gap between
moving sandpaper and fixed table/support creates
a pinch point for fingers or workpieces; the larger
this gap is, the greater risk of fingers or workpieces
getting caught in it. Minimize this risk by adjusting
table no more than
1
⁄16 ” away from sandpaper.
WORKPIECE SUPPORT. Workpiece kickback
can occur with violent force if workpiece is not
properly supported during operation. Always sand
with workpiece firmly against table or another support device.
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.
SANDPAPER CONDITION. Worn or damaged
sandpaper not only produces poor sanding results,
but could fly apart, aggressively grab workpiece,
and throw debris at the operator. Always inspect
sandpaper before operation and replace if worn or
damaged.
WORKPIECE INTEGRITY. Only sand solid workpieces that can withstand power sanding forces.
Make sure shape of workpiece is properly supported on table; avoid sanding workpieces without flat
bottom surfaces unless some type of jig is used to
maintain support and control when sanding force
is applied.
SANDING DUST. Sanding creates large amounts
of dust and flying chips that can lead to eye injury
or respiratory illness. Reduce risk of these hazards
by wearing approved eye and respiratory protection when using sander.
DUST COLLECTION. Never operate without ade-
quate dust collection system in place and running.
Proper dust collection reduces dust in work area,
which decreases risk of long-term respiratory damage, but it is not a substitute for using a respirator.

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.
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
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:

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.
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:
Grounding 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.

Anchoring to Floor
Anchoring machinery to the floor prevents tipping
or shifting and reduces vibration that may occur
during operation, resulting in a machine that runs
slightly quieter and feels more solid.
If the machine will be installed in a commercial or
workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes
may require that it be anchored to the floor.
If not required by any local codes, fastening the
machine to the floor is an optional step. If you
choose not to do this with your machine, we recommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.
Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the
floor surface, making it easy to unbolt and move
the machine later, if needed. However, anytime
local codes apply, you MUST follow the anchoring
methodology specified by the code.

Dust Collection
Once assembly is complete, test run the machine
to ensure it is properly connected to power and
safety components are functioning properly.
If you find an unusual problem during the test run,
immediately stop the machine, disconnect it from
power, and fix the problem BEFORE operating the
machine again. The

Operating an improperly set up machine
Serious injury or death can result from
This machine creates substantial amounts
of 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.
Recommended 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

Attaching Sandpaper
Disc Sanding
The Model G0775 sander accepts 20" diameter
PSA (pressure-sensitive adhesive) sanding discs.
These are available in a variety of grits. The sandpaper can be replaced without removing the table.
To attach sandpaper:
1. DISCONNECT MACHINE FROM POWER!
2. Loosen six hex bolts that secure table to
support brackets, and move table away from
sanding disc.
3. Remove disc guard, peel off old sandpaper,
clean disc surface with mineral spirits, and
wipe it dry.
4. Peel back protective layer on one-half of
sandpaper disc and fold it against remaining
half.
5. Slip half with protective layer between disc
and the table edge (see Figure 9).
The Model G0775 uses a dual-axis miter slot
design for increased versatility of workpiece control.
Always keep disc guard in place and
workpiece on side of wheel that is rotating
downward. This will reduce likelihood of
workpiece being ejected.
To reduce risk of your fingers getting
trapped between work table and sanding
disc, make sure the table is approximately
1
⁄16" away from sanding disc.
To use sanding disc:
1. DISCONNECT MACHINE FROM POWER!
Figure 9. Installing sandpaper.
6. Position exposed adhesive on upper half of
disc that extends above table. Once it is positioned evenly across disc, press adhesive
onto surface.
7. Rotate disc so lower half is above table. Peel
off other half of protective paper, and press
remaining sandpaper against disc so adhesion is complete.
2. Set angle of table and miter gauge for your
operation.

Note: You can use the included radius sanding
attachment to sand round workpieces. Insert the
sanding attachment into the Y-axis. Mark the center of the workpiece with an awl or center punch.
Place the center mark over the pivot point of the
sanding attachment. Spin the workpiece clockwise against the down-spin side of the rotating
disc.
Note: To perform sanding on compound-angle
cuts, tilt the table and rotate the miter gauge to the
appropriate angles.
Note: To prevent burning the workpiece and over-
loading the sanding disc, move the workpiece
slowly back and forth from the left side of the
sanding disc to the center and do not use excessive pressure.
