Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect 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 machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

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.
nect machine from power supply BEFORE mak­ing adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unin­tended startup or contact with live electrical com­ponents.

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.

Always discon-

Model G0944/G0944HEP (Mfd. Since 03/21)

-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 mate­rial. 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.

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 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.

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 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.

EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend­ed operation, stop using the machine! Contact our
Technical Support at [phone].

Additional Safety for Dust Collectors

of death or injury caused by explosions or fires, DO

Long-term respiratory damage can occur from using dust collectors without proper use of a
respirator. Fire or explosions can result in smoke inhalation, serious burns, or death—if machine
is used to collect incorrect materials, is operated near potential explosion sources, or ducting is
improperly grounded. Entanglement, amputation, or death can occur if hair, clothing, or fingers
are pulled into the inlet. To reduce the risk of these hazards, operator and bystanders MUST
completely heed the hazards and warnings below.

INTENDED USE. Collecting the wrong materi-

als can result in serious inhalation hazards, fire,
explosions, or machine damage. This machine
is ONLY designed to collect wood dust and chips
from woodworking machines. DO NOT use it to
collect silica, polyurethane, toxic fumes, metal dust
or shavings, lead paint, drywall, asbestos, biohaz­ards, explosive dusts, flammable or combustible
liquids or fumes, nor burning or smoking material.

WEAR A RESPIRATOR. Fine dust that is too
small to be caught in filter will be blown into ambi­ent air. Always wear a NIOSH-approved respira­tor during operation and for a short time after to
reduce your risk of permanent respiratory damage.
Never collect dust from any hazardous material.

IMPELLER HAZARDS. To reduce risk of entan­glement or contact with impeller, DO NOT place
hands, hair, clothing, or tools in or near open dust
collection inlet during operation, and keep small
animals and children away. The powerful suction
could easily pull them into impeller.

HAZARDOUS DUST. Dust exposure 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.

EMPTYING DUST. When emptying bag or drum,
wear respirator and safety glasses. Empty dust
away from ignition sources and into approved
container.

OPERATI NG LOCATION . To reduce respiratory
exposure to fine dust, locate permanently installed
dust collectors away from working area or in anoth­er room. DO NOT place dust collector where it can
be exposed to rain or moisture, which creates a
shock hazard and will reduce life of machine.

POWER DISCONNECT. Turn machine OFF, dis-
connect from power supply, and allow impeller
to completely stop before leaving machine unat­tended, or doing any maintenance or service.

REGULAR CLEANING. To reduce risk of start­ing a fire, regularly check/empty collection bags
or drum to avoid buildup of fine dust, which can
increase risk of fire. Regularly clean surrounding
area where machine is operated—excessive dust
buildup on overhead lights, heaters, electrical pan­els, or other heat sources will increase risk of fire.

SUSPENDED DUST PARTICLES. To reduce risk

NOT operate in areas where these risks are high,
including spaces near pilot lights, open flames, or
other ignition sources.

AVOIDING SPARKS. To reduce risk of fire, avoid
collecting any metal objects or stones. These can
possibly produce sparks when they strike impeller,
which can smolder in wood dust for a long time
before a fire is detected. If you accidentally cut
into wood containing metal, immediately turn OFF
dust collector, disconnect from power, and wait
for impeller to stop. Then empty bag or drum into
approved airtight metal container.

FIRE SUPPRESSION. Only operate dust collector
in locations that contain fire suppression system or
have fire extinguisher nearby.

STATIC ELECTRICITY. To reduce risk of fire or
explosions caused by sparks from static electricity,
ground all ducting using grounding wire.

DUST ALLERGIES. Dust from certain woods will
cause an allergic reaction. Make sure you know

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.

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.)

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

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:

SECTION 4: DESIGNING A SYSTEM

General

Always make sure there are no open flames
or pilot lights in the same room as the dust
collector. There is a risk of explosion if too
much fine dust is dispersed into the air with
an open flame present.

Always guard against stat­ic electrical build up by
grounding all dust collec­tion lines.

The Model G0944/G0944HEP works quite well as
a point-of-use dust collector, or for collecting dust
from up to two machines simultaneously.

Tips for Optimum Performance

• Avoid using more than 10' of flexible hose on
any ducting line. The ridges inside flexible
hose greatly increase static pressure loss,
which reduces suction performance.

• Keep ducts between the dust collector and

machines as short as possible.

• Keep ducting directional changes to a mini-

mum. The more curved fittings you use, the
greater the loss of suction at the dust-produc­ing machine.

Gradual directional changes are more effi-

•

cient than sudden directional changes (i.e.
use 45° elbows in place of 90° elbows when­ever possible).

The simpler the system, the more efficient

•

and less costly it will be.

System Grounding

Since plastic hose is abundant, relatively inexpen­sive, easily assembled and air tight, it is a very
popular material for conveying dust from wood­working machines to the dust collector.

We recommend only using short lengths of flex­ible hose (flex-hose) to connect the woodworking
machine to the dust collector. However, plastic
flex-hose and plastic duct are an insulator, and
dust particles moving against the walls of the
plastic duct create a static electrical buildup. This
charge will build until it discharges to a ground.

If a grounding medium is not available to prevent
static electrical buildup, the electrical charge will
arc to the nearest grounded source. This electri­cal discharge may cause an explosion and subse­quent fire inside the system.

To protect against static electrical buildup inside
a non-conducting duct, a bare copper wire should
be placed inside the duct along its length and
grounded to the dust collector. You must also
confirm that the dust collector is continuously
grounded through the electrical circuit to the elec­tric service panel.

If you connect the dust collector to more than one
machine by way of a non-conducting branching
duct system and blast gates, the system must still
be grounded as mentioned above. We recom­mend inserting a continuous bare copper ground
wire inside the entire duct system and attaching
the wire to each grounded woodworking machine
and dust collector.

Be sure that you extend the bare copper wire down
all branches of the system. Do not forget to con­nect the wires to each other with wire nuts when
two branches meet at a “Y” or “T” connection.

Ensure that the entire system is grounded. If using
plastic blast gates to direct air flow, the ground­ing wire must be jumped (see the figure below)
around the blast gate without interruption to the
grounding system.

We also recommend wrapping the outside of all

in your electric service panel.

Canister Filter

This dust collector uses a filter cleaning handle
to remove dust buildup and debris from the filter
pleats and extend the life of the filter. Clean the
filter with the filter cleaning handle after each use,
or whenever dust collection performance drops.
Eventually, dust will become fully embedded in
the filter pleats, and the filter assembly will have to
be replaced. If you reach the point where cleaning
the filter does not improve performance, then it is
time to replace the filter.

IMPORTANT: DO NOT use water or high pres­sure to clean canister filter. Doing so will damage
the filter and reduce filtration.

These pages are current at the time of printing. However, in the spirit of improvement, we may make chang­es to the electrical systems of future machines. Compare the manufacture date of your machine to the one

number and manufacture date of your

machine before calling. This information can be found on the main machine label.

SECTION 9: WIRING

stated in this manual, and study this section carefully.

If there are differences between your machine and what is shown in this section, call Technical Support at
[phone] for assistance BEFORE making any changes to the wiring on your machine. An updated
wiring diagram may be available. Note: Please gather the serial

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
Support at [phone].
