Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip-
ment, such as those dust masks that are specially designed to filter

NOTICE
Safety Instructions for Machinery
SECTION 1: SAFETY
Model G1140 G1531 (Mfd. Since 08/14)
-9-
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 mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing 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 modifica-
tions—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.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
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 dur-
ing 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 rec-
ommended accessories. Using improper acces-
sories 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.
DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!
MAINTAIN POWER CORDS. When disconnect-
ing 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.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend-
ed operation, stop using the machine! Contact our
Technical Support at (570) 546-9663.

Model G1140 G1531 (Mfd. Since 08/14)
Additional Safety for Edge Sanders
FEEDING WORKPIECE. Forcefully jamming work-
piece 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.
SMALL WORKPIECES. Small workpieces are
difficult to control and require close support near
sanding surface. Always use a jig or other holding
device when sanding small workpieces, and keep
hands and fingers at least 2" away from sanding
surface.
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 ques-
tionable 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.
SANDING DUST & DUST COLLECTION.
Sanding creates large amounts of dust and flying
particles that can lead to eye injury or respiratory
illness. Reduce risk by wearing approved eye and
respiratory protection when using sander. Never
operate without adequate dust-collection system in
place and running. Proper dust collection reduces
dust in work area, decreasing risk of long-term
respiratory damage, but it is not a substitute for
using a respirator.
Serious injury or death can occur if fingers, clothing, jewelry, or hair get entangled in moving
components. Impact injuries can occur from kickback if workpiece is improperly fed into moving
sandpaper. Serious pinch injuries can occur from touching in-running nip point between table
and sanding surface. 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.
AVOIDING ENTANGLEMENT. Becoming entan-
gled 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.
SANDPAPER DIRECTION. Feeding workpiece
incorrectly can cause it to be thrown from machine,
striking operator or bystanders, or causing your
hands to slip into the moving sandpaper. To
reduce these risks, only sand against direction of
sandpaper travel, ensure workpiece is properly
supported, and avoid introducing sharp edges into
moving sandpaper on leading side of workpiece.
WORKPIECE SUPPORT & HAND PLACEMENT.
Rotating sandpaper can remove a large amount
of skin quickly, and kickback can occur with vio-
lent force if workpiece is not properly supported
during operation. Always sand with workpiece
firmly against table or another support device.
Never touch moving sandpaper on purpose.
WORKPIECE INTEGRITY. Only sand solid work-
pieces that can withstand power sanding forces.
Make sure shape of workpiece is properly support-
ed 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.

SECTION 2: POWER SUPPLY
Availability
Before installing the machine, consider the avail-
ability 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, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
Full-Load Current Rating
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.
Full-Load Current Rating at 220V ..... 10 Amps
Full-Load Current Rating at 110V ...... 20 Amps
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 over-
loading 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
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
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, con-
sult 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 sup-
ply 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.)

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 nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel 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, discon-
nect it from power, and immediately replace it with
a new one.
Extension Cords
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:
Minimum Gauge Size ...........................12 AWG
Maximum Length (Shorter is Better).......50 ft.
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.
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!
No adapter should be used with plug. If
plug does not fit available receptacle, or if
machine must be reconnected for use on a
different type of circuit, reconnection must
be performed by an electrician or qualified
service personnel, and it must comply with
all local codes and ordinances.
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.

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 7 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
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 6. For thor-
ough cleaning, some parts must be removed.
For optimum performance, clean all moving
parts or sliding contact surfaces. Avoid chlo-
rine-based solvents, such as acetone or brake
parts cleaner that may damage painted surfac-
es. Always follow the manufacturer’s instructions
when using any type of cleaning product.
Cleanup
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.
