Additional Safety for Metal Dust Collectors
Long-term respiratory damage, metal toxicity, cancer, or birth defects can occur from improperly
using, setting up, or servicing machine, and using this machine without wearing a respirator.
Explosions or fire can result if machine is used to capture incorrect materials or if dust/waste
material is exposed to an ignition source. To reduce these risks, operator and bystanders MUST
completely heed the warnings below.
USE FOR INTENDED PURPOSE. This metal
dust collector is only designed to capture noncombustible or non-explosible metal particles.
Collect only one type of metal/material at one
time. DO NOT use to capture materials made
from wood or wood products. DO NOT use it to
collect lead, magnesium, niobium, tantalum, titanium, zirconium, hafnium, asbestos, crystalline
silica, gypsum, or any other non-metal products.
DO NOT use to capture welding fumes, gasses,
vapors, liquids, smoke, or ordinary combustible
materials. DO NOT connect this dust collector to
any machine using a coolant system.
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 being collected. Very fine dust/particles
may not be captured by filters and may become
airborne in the work area. Anyone working in this
same work area MUST wear a NIOSH-approved
respirator and eye protection rated for the workpiece material.
RISK OF FIRE/EXPLOSIONS. To minimize static
electrical charge, only connect with smoothwalled, sheet-metal ducting—do not use PVC.
Entire collection system (collector + ductwork)
must be bonded and grounded. Fine metal dust
particles can ignite, depending on material type
and circumstances. Know about and be prepared
to safely fight a combustible metal fire by conducting a combustible screening test under Chapter
4 of NFPA 484. Keep machine away from pilot
lights, open flames, or other ignition sources.
NEVER use near chemical fumes or within an
enclosed spray booth.
-8-
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 toxicity of metal types
you work with and always seek to minimize/eliminate exposure to yourself and others.
CLEANING DRAWERS. Wear safety goggles
and a NIOSH-approved respirator (rated for the
metal type) when emptying and cleaning collection drawer and dust tray. Empty only into an
approved, closed-top metal container, taking care
to minimize amount of dust allowed to become
airborne. Prevent spread of dust onto hands or
clothing. Dispose of waste properly and according
to local regulations for material type.
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
metal dust collector where it can be exposed to
rain or moisture. Exposure to water creates a
shock hazard and will reduce life of machine.
PROPERLY MAINTAIN MACHINE. Keep machine
in proper working condition to help ensure all
guards and components function as intended.
Perform routine inspections and all necessary
maintenance indicated in owner’s manual. Never
operate machine with damaged or worn parts.
Duct must be disconnected before service. Never
operate machine with filters or covers removed.
Model T28798 (Mfd. Since 12/18)
SECTION 2: POWER SUPPLY
Availability
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.
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 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 overloading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
Model T28798 (Mfd. Since 12/18)
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.
Circuit Information
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.)
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, consult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
Circuit Requirements for 240V
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage.......... 208V, 220V, 230V, 240V
Cycle...........................................................60 Hz
Phase............................................ Single-Phase
Power Supply Circuit.......................... 15 Amps
Plug/Receptacle.............................. NEMA 6-15
-9-
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!

Current Carrying Prongs
6-15 PLUG
Grounding Pin
Figure 1. Typical 6-15 plug and receptacle.
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.
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............................14 AWG
Maximum Length (Shorter is Better).......50 ft.
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.

Ducting System
Overview
This dust collector is designed exclusively to collect dry metal, chips, and swarf. DO NOT use this
dust collector to collect wood dust or metal chips
containing cutting fluid or coolant. Due to fire or
explosion risk, DO NOT use this machine to collect combustible or explosive metals, magnesium,
niobium, tantalum, titanium, zirconium, hafnium,
combustible liquids or fuels, gasoline, or oil- or
solvent-based paints.
For best performance, place this dust collector
as close to dust-generating machines as possible
and install blast gates at the beginning of ducting
lines. Only open one line at a time to focus maximum suction at the machine where dust is being
collected.
Grizzly offers a complete line of dust collection
accessories for setting up your dust collection
system ductwork (see Page 21) and a complete
guide book titled Dust Collection Basics.
Whatever system design you choose, always
make sure to position ducting and collector away
from any open flames (including pilot lights);
otherwise you risk an explosion if material is dispersed into the air.
Metal Ducting
Advantages of metal ducting is its conductivity
and that it does not contribute to static electrical
charge build-up. However, static charges are still
produced when particles strike other dust particles as they move through the duct. Since metal
duct is a conductor, it can be grounded quite
easily to dissipate any static electrical charges.
Replace any plastic dust ports with sheet-metal
equivalents, or bond sheet metal ducting to metal
frame of machine with grounding wire.
Always guard against static electrical build up by
grounding all collection
lines.
There are a number of options when it comes to
metal duct, but duct that is specially manufactured
for metal dust collection is the best choice. When
selecting your metal duct, choose high-quality
metal duct with smooth-welded internal seams
that will minimize airflow resistance. This type of
duct usually connects to other ducts or elbows
with a simple, self-sealing clamp, is very quick
and easy to assemble, and can be readily dismantled and re-installed. This is especially important
if you ever need to change things around in your
shop or add more tools.
Duct Material
For best results, use only smooth-wall, sheetmetal ducting or flexible metal ducting to connect
each machine.
The National Fire Protection Agency (NFPA)
warns of explosion or fire hazard because of static
electrical buildup if plastic or non-conductive duct
material is used for metal dust collection and is
not completely grounded and bonded. We DO
NOT recommend using any plastic duct material
with this machine.
Model T28798 (Mfd. Since 12/18)
Figure 11. Examples of metal duct and
components.
Avoid inferior metal duct that requires you to cut it
to length and snap it together. This type of duct is
time-consuming to install because it requires you
to seal all the seams with silicone and screw the
components on the ends with sheet-metal screws.
Another disadvantage is the rough internal seams
and crimped ends that unavoidably increase static
pressure loss.
-17-
Flexible Duct
System Grounding
Flexible hose is generally used for short runs and
at rigid duct-to-machine connections. The superior choice here is metal flex hose that is designed
to be flexible, yet be as smooth as possible inside
to reduce static pressure loss. DO NOT use dryer
vent hose because it tends to collapse.
To guard against static electrical buildup, we
strongly recommend replacing any plastic dust
ports on dust-producing machines with metal
equivalents.
Figure 12. Example of flexible metal duct.
If you absolutely must use any plastic duct or
components, they must be completely grounded
and bonded to the metal frame of a grounded
machine by wrapping the flex hose with an external ground wire connected to both machines as
shown in Figure 14. Ensure that each machine is
continuously grounded to the grounding terminal
in your electric service panel.
Ensure Required CFM at Machine
Since each machine produces a different amount
of dust, the requirements for the minimum amount
of CFM to move that dust is unique to the machine.
Knowing this required CFM is important to gauging what size duct to use.
For best results when using the Y-inlet, we recommend installing blast gates to control airflow for
each line near the Y-inlet.
Refer to Figure 13 for a close estimation of the
airflow each dust-producing machine requires.
Machines that generate the most dust should be
placed as close as possible to the dust collector.
