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
out microscopic particles.

ELECTRICAL EQUIPMENT INJURY RISKS.
You can be shocked, burned, or killed by touching
live electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.
Always discon-
nect machine from power supply BEFORE mak-
ing adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unin-
tended startup or contact with live electrical com-
ponents.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained oper-
ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis-
connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin-
ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

NOTICE
Safety Instructions for Machinery
SECTION 1: SAFETY

-8- Model G0964 (Mfd. Since 04/23)
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 [phone].

Model G0964 (Mfd. Since 04/23) -9-
Additional Safety for Fume Extractors
TOXIC FUMES. Welding produces hazardous
fumes that can suffocate or poison without warn-
ing. Reduce this risk by researching consumables
needed for operation, atmospheric contaminants,
materials, and material coatings, and take neces-
sary precautions for fumes that will be produced.
Use ANSI-approved respirator for applicable type
of operation and protect others from fumes.
Position hood near workpiece to extract fumes
before they spread throughout and contaminate
work area. If extractor malfunctions, immediately
stop and correct the issue.
FLAMMABLE MATERIALS. Keep flammable
materials and vapors away from fume extractor
and welding operation. Sparks from welding oper-
ation and heat from fumes present a fire hazard.
WELDING SAFETY. Welding without approved
personal protective equipment can cause severe
damage to eyes and body. Read and understand
all safety warnings provided by manufacturer for
any welder you plan to use with fume extractor
and take proper precautions.
ADEQUATE VENTILATION. Do not use fume
extractor in confined space without adequate
ventilation. Fume extractors do not replace oxy-
gen that is consumed by welding operations.
Suffocation or explosion can occur if this warning
is ignored. Open covers, doors, and windows to
sustain fresh air ventilation or use an additional
form of mechanical ventilation to ventilate space.
Those inside work area should wear air-line respi-
rators. Have personnel monitor operator from out-
side operating area in case of equipment failure.
INSPECTIONS/MAINTENANCE. Always inspect
equipment and all seals/gaskets prior to opera-
tions. Repair or replace defective components
before starting. Stop welding operation if fume
extractor is leaking or malfunctions.
Welding fumes can cause suffocation or poisoning if operating in an enclosed space without
adequate ventilation and fume extraction.All users must be properly trained on the potential
hazards, manufacturer’s operating procedures, use of personal protective equipment (PPE),
emergency procedures, and safety precautions for welding operations. To reduce these risks,
operator and bystanders MUST completely heed the warnings below.
FUME EXTRACTION. NEVER modify machine or
bypass safety features. Machine is not designed
to collect wood, glass, asbestos, lead paint dust,
silica, animal parts, biohazards, burning materi-
als/ashes, combustible dust, flammable liquids or
gases, sprayed paint, burning slag, molten metal,
or fumes from laser engravers/cutters. Always
position hood to only collect smoke and fumes,
and operate machine with all filters and covers in
place. If any filter is missing or replaced with non-
specification filter, fume extractor will not properly
filter contaminated air and will be unsafe to use.
FILTER CLEANING/DISPOSAL. Filters and dust
drawer must be changed regularly according to
the frequency of use, or as specified by manufac-
turer. When servicing filters, make sure operator
and any bystanders are wearing personal protec-
tive equipment. When cleaning filters and cabi-
net, do not use compressed air. Only use a shop
vacuum that is equipped with a HEPA filter, or
dangerous particulates may be spread throughout
the area and contaminate the air. Wrap all waste
filters in air-tight plastic bags, then mark and dis-
pose of according to current laws and regulations.
MOVING. Use base handle, not arm, to move
machine. Moving machine by arm could damage
it and reduce air flow efficiency and machine's
ability to extract dangerous fumes. Lock casters
prior to adjusting arm to avoid dragging machine
and putting unnecessary stress on arm.
EXPERIENCING DIFFICULTIES. Keep in mind
that welding hazards are intensified in a confined
space. If you are experiencing difficulties perform-
ing the intended operation, stop using the equip-
ment, and contact the Occupational Safety and
Health Administration (OSHA) at [phone],
or online at www.osha.gov to find out how to
design and maintain the best overall welding fume
extraction system for your needs.

Welding metals can give off poisonous fumes containing zinc, lead, beryllium, cadmium, mercury,
fluorine, hexavalent chromium, and others. These fumes typically originate from fluxes, anti-
corrosion coatings, pigments, metal fillers, and residual chemicals on the workpiece. This machine
is designed to help meet the welding shop clean air requirements mandated by OSHA beginning in
2006. The Model G0964 Portable Fume Extractor is designed to be a part of an overall fume control
system. It is NOT designed to serve as a "single-solution" for keeping workers safe from all welding
fumes. You must contact OSHA to find out how to design and maintain the best overall welding fume
control system for your work station or shop. Often, depending on the workspace size, volume of
work, type of material to be welded, or other special circumstances, you must use additional safety
equipment such as personal air line respirators, hoods, masks, and complete body protection.

Model G0964 (Mfd. Since 04/23) -11-
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 120V ..... 18 Amps
Full-Load Current Rating at 240V ....... 9 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.)

This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Circuit Requirements for 120V
Nominal Voltage .................... 110V, 115V, 120V
Cycle ..........................................................60 Hz
Phase ........................................... Single-Phase
Power Supply Circuit ......................... 20 Amps
Plug/Receptacle ............................. NEMA 5-20

-12- Model G0964 (Mfd. Since 04/23)
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 (120V) ...............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.

SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug provided—if
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.
For 120V operation: This machine is equipped
with a power cord that has an equipment-ground-
ing wire and a grounding plug (see following fig-
ure). The plug must only be inserted into a match-
ing receptacle (outlet) that is properly installed
and grounded in accordance with all local codes
and ordinances.
For 240V operation: The plug specified under
“Circuit Requirements for 240V” on the previ-
ous page has a grounding prong that must be
attached to the equipment-grounding wire on
the included power cord. The plug must only be
inserted into a matching receptacle (see following
figure) that is properly installed and grounded in
accordance with all local codes and ordinances.
