Additional Safety for Downdraft Tables
Long-term respiratory damage, cancer, or birth defects can occur from using this machine
without proper use of a respirator. Explosions or fire can result if machine is used to capture
incorrect materials or dust/waste material is exposed to an ignition source. To reduce these
risks, operator and bystanders MUST completly heed the warnings below.
USE FOR INTENDED PURPOSE. This down-
draft table is designed to capture sparks and
particles created while grinding certain metals.
DO NOT use it to capture materials made from
wood or wood products, lead, magnesium, asbestos, crystalline silica, gypsum, or any other nonmetal products. DO NOT use it to capture welding
fumes, gasses, vapors, liquids, or smoke.
WEAR PROPER PPE. Dust created from cutting,
grinding, sanding, etc. may cause cancer, birth
defects, or long-term respiratory damage. Be
aware of the dust hazards, exposure limits, and
toxicity associated with each type of workpiece
material. Very fine dust/particles are unlikely to be
captured and may become airborne in the work
area. Anyone working with or around this machine
MUST wear a NIOSH-approved respirator rated
for the workpiece material.
TOXIC METALS. Exposure (or over-exposure) to
certain types of metal dusts or fumes can result
in serious, potentially deadly health effects. To
reduce this risk, research toxic effects of metal
types you work with and always seek to minimize/
eliminate exposure to yourself and others.
CLEANING DRAWERS. Wear safety glasses
and a NIOSH-approved respirator rated for the
waste metal type when emptying and cleaning
drawers. Empty only into an approved container,
taking care to minimize amount of dust allowed to
become airborne and prevent spread onto hands
or clothing. Dispose of waste properly.
HIGH-HAZARD MATERIAL. This machine does
NOT protect against highly hazardous materials,
such as lead dust, asbestos fibers, or radioactive
particles. These materials MUST be collected
with special filtration equipment because of their
high health/contamination hazard and difficulty of
filtration. DO NOT attempt to collect such materials with this machine.
SAFE OPERATING LOCATION. DO NOT place
downdraft table where it can be exposed to rain
or moisture exposure to water creates a shock
hazard and will reduce life of machine.
RISK OF FIRE/EXPLOSIONS. Fine metal dust
particles can ignite, depending on material type
and circumstances. Keep machine away from
pilot lights, open flames, or other ignition sources.
NEVER use near chemical fumes or within an
enclosed spray booth. NEVER use to capture
magnesium particles—as these particles can
ignite from exposure to water/moisture.
PROPERLY MAINTAIN MACHINE. Ke e p machine
in proper working condition to help ensure all
guards and other components work as intended
and function safely. Perform routine inspections
and all necessary maintenance, as indicated in
owner’s manual. Never operate machine with
damaged or worn parts. Never operate machine
with filters, guards, or covers removed.

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.
or equipment damage
may occur if machine is
not properly grounded
and connected to 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.
process. DO NOT connect to power until
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.
For 110V operation: This machine is equipped
with a power cord that has an equipment-grounding wire and a grounding plug (see following figure). The plug must only be inserted into a matching receptacle (outlet) that is properly installed

Wiring Safety Instructions
SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical components!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
This includes the installation of unapproved aftermarket parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires disconnected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious personal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information
included in this section, contact our Technical
