The following is a list of common definitions, terms and phrases that relate to dust collection and dust col-
lectors in general. To get the most out of this manual, familiarize yourself with these terms before reading.
Air Suction Capacity:
The maximum volume
of air (rated in CFM) that a dust collector can
move, at the inlet, when fully assembled and
not connected to any ducting.
Branch Line:
A secondary length of duct that
connects a dust-producing machine to the
Main Line of a permanent dust collection sys-
tem. The minimum recommended Velocity for
branch lines is 4000 FPM.
Collection Bag/Drum:
The part of the dust col-
lector that holds the majority of captured dust.
CFM (Cubic Feet per Minute):
A measurement
describing the volume of air that moves through
an area in one minute. CFM = Velocity (FPM) x
Cross-Sectional Area of Duct (ft.2).
Cyclone:
A type of two-stage dust collector that
uses centrifugal force to remove large dust par-
ticles before they can reach the filter.
Duct (Ducting):
Metal/plastic pipe or hose that
connects the dust collector to dust-producing
machines. Typically available in rigid or flexible
options.
Dust Collection System:
The entire assembly of
dust collector, duct, and fittings used to capture
dust from machines.
Dust Port/Hood:
The part of a dust-producing
machine that connects to dust collection duct.
Filter:
The part of the dust collector that prevents
the majority of suctioned dust from returning to
the shop environment. Filters are rated by the
size of fine dust (measured in microns) that can
pass through them.
Fittings (Y's, T's, Elbows, etc.):
The various
duct connections that allow the branch and
main lines of a dust collection system to be
routed from the machine to the dust collector.
Duct Grounding: A method of using bare wire
with plastic duct to safely dissipate static elec
-
tricity buildup during operation.
Main Line: The primary length of duct that con
-
nects the dust collector to the branch lines of
a permanent dust collection system. The mini
-
mum recommended Velocity for main lines is
3500 FPM.
Machine CFM Requirement: Indicates the mini
-
mum amount of airflow required at the dust port/
hood of a dust-producing machine for adequate
removal of the waste produced. Essentially, the
performance required by the
Dust Collection
System after accounting for the drop in CFM
from the static pressure loss of the duct line
between the machine and the dust collector.
Powered Air Filter: An independently operated
machine that removes fine dust suspended in
the air. Typically operated during and after dust-
producing operations as a secondary method
to improve the air quality in a shop.
Single-Stage Collector: A type of dust collector
where all collected chips and dust are expelled
directly into the filter.
Static Pressure: Expressed in units of inches of
water, this describes the difference in pressure
between the air inside and outside the dust col
-
lector. It is a measure of the suction created by
the blower.
Two-Stage Collector: A type of dust collector
where large/heavy waste is captured in a sepa
-
rate container before the airflow reaches the
filter. Benefits include longer operation times
between filter maintenance or replacement.
Velocity: The speed of airflow movement, mea
-
sured in FPM (Feet Per Minute). Velocity =
Volume (CFM) / Cross-Sectional Area of Duct
(ft.2).

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.
For Your Own Safety, Read Instruction
Manual Before Operating This Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor-
tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
Alerts the user to useful information about proper operation of the
machine to avoid machine damage.
NOTICE
Safety Instructions for Machinery
SECTION 1: SAFETY

-12- Model G0777/G0777HEP (Mfd. Since 04/19)
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.

Additional Safety for Dust Collectors
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.
POWER DISCONNECT. Turn machine OFF, dis-
connect from power supply, and allow impeller
to completely stop before leaving machine unat-
tended, or doing any maintenance or service.
REGULAR CLEANING.
To reduce risk of start-
ing 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 pan-
els, or other heat sources will increase risk of fire.
SUSPENDED DUST PARTICLES. To reduce risk
of death or injury caused by explosions or fires, DO
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
what type of wood dust you will be exposed to in
case of an allergic reaction.
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, biohaz-
ards, 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 ambi-
ent air. Always wear a NIOSH-approved respira-
tor 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 entan-
glement 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.
OPERATING LOCATION. To reduce respiratory
exposure to fine dust, locate permanently installed
dust collectors away from working area or in anoth-
er 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.

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 110V...... 15 Amps
Full-Load Current Rating at 220V .... 7.5 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.
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.)
Circuit Information
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.

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.
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.
