WARNING
Some dust created by power sanding, sawing, grind-
ing, 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 equipment, such
as those dust masks that are specially designed to fil-
ter out microscopic particles.

Additional Safety Instructions For
The Dust Collector
5. DO NOT ALLOW STEEL TO STRIKE
AGAINST STEEL WHICH MAY PRODUCE
A SPARK. Sparks can smolder in wood
dust for a long time before fire or flame is
detected. If metal contacts metal during
operation, immediately turn off the dust col-
lector, unplug the power cord from the outlet
or flip the disconnect switch and wait for all
moving parts to stop. Remove collection
bags and empty the dust into an approved
air tight metal container in case of spark.
Remedy the metal to metal contact problem
before resuming operation.
6. WHEN EMPTYING DUST FROM THE
COLLECTION BAGS,wear a respirator
and safety glasses. Empty dust into an
approved container and dispose of properly.
7. IF AT ANY TIME YOU ARE EXPERIENC-
ING DIFFICULTIES PERFORMING THE
INTENDED OPERATION,stop using the
machine! Then contact our service depart-
ment or ask a qualified expert how the oper-
ation should be performed.
8. BE AWARE THAT CERTAIN WOODS
MAY CAUSE AN ALLERGIC reaction in
people and animals, especially when
exposed to fine dust. Make sure you know
what type of wood dust you will be exposed
to in case there is a possibility of an allergic
reaction. Always wear an approved respira-
tor!
1. THIS DUST COLLECTOR IS TO BE USED
FOR WOOD DUST COLLECTION ONLY.
Do not use this dust collector to pick up liq-
uids and metal scrap including, but not lim-
ited to, nails and filings. Metallic debris will
contact the spinning impeller and could
spark. The spark could then cause a saw-
dust explosion and severe fire hazard. Also,
do not pick up material which cannot safely
pass through the impeller such as solid
wood scraps.
2. DO NOT PLACE YOUR HANDS OR
TOOLS NEAR THE OPEN INLET during
operation for any reason including, but not
limited to, unclogging material and testing
suction. The impeller could cause serious
damage to body parts if touched while spin-
ning.
3. PROBLEMS CONCERNED WITH ANY
MOVING PARTS or accessories must be
investigated and corrected with the power
disconnected and after everything has
come to a complete stop.
4. SUSPENDED DUST PARTICLES IN CON-
JUNCTION WITH AN IGNITION SOURCE,
may cause an explosion. Do not operate the
dust collector in areas where explosion risks
would be high if dust were dispersed into the
area. Areas of high risk include, but are not
limited to, areas near pilot lights and/or open
flames.
No list of safety guidelines can be com-
plete. Every shop environment is different.
Always consider safety first, as it applies to
your individual working conditions. Use
this and other machinery with caution and
respect. Failure to follow guidelines could
result in serious personal injury, damage to
equipment or poor work results.
DO NOT use the dust collector for any other
purpose besides collecting dust from con-
nected woodworking machines. A dust col-
lector should NEVER be used as an air
cleaner. For safest use, wear a dust mask
and use an air cleaner in addition to the
dust collector.

SECTION 2: CIRCUIT REQUIREMENTS
G1028Z Wiring
The G1028Z Dust Collector is pre-wired for 110V,
but can be rewired for 220V. Refer to the wiring
diagram included with this manual for instruction.
Do not attempt to rewire the motor if the diagram
is missing. Contact the appropriate service center
for more information.
A plug is not provided with the G1028Z. It will be
necessary to purchase a standard 110V plug from
your local hardware store. If you are rewiring for
220V, see Figure 1 for the recommended 220V
receptacle.
Circuit Breaker: The 11⁄2H.P. motor will draw
roughly 18 amps at 110V or 9 amps at 220V. We
recommend a using 20 amp circuit breaker for
110V or 220V operation. Circuit breakers rated
higher will not adequately protect the circuit. If you
are using a fuse, we recommend a 30 amp slow
blow for 110V or 220V operation. Fuses rated
higher will not adequately protect the circuit.

-6- G1028Z/G1029 Dust Collector
We do not recommend the use of extension cords
with 220V equipment. Instead, arrange the place-
ment of your equipment and the installed wiring to
eliminate the need for extension cords. Should
the situation be necessary to use an extension,
make sure the cord is rated Hard Service (grade
S) or better. Refer to the chart in Section 1:
Safety Instructions to determine the minimum
gauge for the extension cord when using either
110V or 220V. The extension cord must also con-
tain a ground wire and plug pin. Always repair or
replace extension cords when they become worn
or damaged.

Clean Up
The unpainted surfaces are coated with a waxy oil
to protect them from corrosion during shipment.
Remove this protective coating with a solvent
cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. Avoid chlorine-based
solvents as they may damage painted surfaces
should they come in contact. Always follow the
usage instructions on the product you choose for
clean up.
Site Considerations
FLOOR LOAD
Your Model G1028Z/G1029 represents a moder-
ate weight load in an average footprint. Most com-
mercial or home shop floors should be sufficient
to carry the weight of the Model G1028Z/G1029.
If you question the strength of your floor, you can
opt to reinforce it.
WORKING CLEARANCES
Working clearances can be thought of as the dis-
tances between machines and obstacles that
allow safe operation of every machine without lim-
itation. Consider existing and anticipated machine
needs, size of material to be processed through
each machine, and space for auxiliary stands
and/or work tables. Also, consider the relative
position of each machine to one another for effi-
cient material handling. Be sure to allow yourself
sufficient room to safely run your machines in any
foreseeable operation and keep dust collection
hoses off the floor and out of the way.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadows and prevent eye strain. Electrical circuits
should be dedicated or large enough to handle
combined motor amp loads. Outlets should be
located near each machine so power or extension
cords are not obstructing high-traffic areas. Be
sure to observe local electrical codes for proper
installation of new lighting, outlets, or circuits.
Do not smoke while using
solvents. A risk of explo-
sion or fire exists and may
result in serious personal
injury.
Make your shop “child
safe.” Ensure that your
workplace is inaccessible
to youngsters by closing
and locking all entrances
when you are away. Never
allow visitors in your shop
when assembling, adjust-
ing or operating equip-
ment.
Do not use gasoline or
other petroleum-based
solvents. They have low
flash points which make
them extremely flamma-
ble. A risk of explosion
and burning exists if
these products are
used. Serious personal
injury may occur if this
warning is ignored.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest-
ed. Always work in well-
ventilated areas far from
potential ignition sources
when dealing with sol-
vents. Use care when dis-
posing of waste rags and
towels to be sure they do
not create fire or environ-
mental hazards.

ments. Failure to do this
may result in serious
personal injury.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Wear safety glasses dur-
ing the entire assembly
process. Failure to com-
ply may result in serious
personal injury.
Some metal parts may
have sharp edges on
them after they are
formed. Please examine
the edges of all metal
parts before handling

Material Selection
General
You have many choices regarding main line and
branch line duct material. In most commercial
workshops, the main line and branch lines are
usually metal duct. Flexible hose is then used to
connect each machine to the branch lines. In the
case of small home shops, flexible hose may be
used for both main line and branch line ducts.
Plastic duct is also a popular material for home
shops. Please be aware that there is a fire or
explosion hazard if plastic duct material is used
for dust collection without being grounded against
static electrical charge build-up. This topic will be
discussed later in the manual.
METAL DUCT
Metal duct comes in many varieties. Stove pipe,
heating/ventilation duct and duct made especially
for dust collection are all options. Advantages of
metal duct is its conductivity and that it does not
contribute to static electrical charge build-up.
However, static charges are still produced when
dust particles strike other dust particles as they
move through the duct. Since metal duct is a con-
ductor, it can be grounded quite easily to dissi-
pate any static electrical charges. However, metal
duct is generally more expensive than plastic duct
and it is not usually airtight unless specifically
manufactured for dust collection. Specially manu-
factured metal duct, on the other hand, is quite
expensive. Metal duct is also generally more diffi-
cult to cut and assemble.
FLEXIBLE HOSE
Flexible rubber hose, polyethylene, plastic flex-
hose and other flexible ribbed hose is generally
used for short runs, small shops and at rigid duct-
to-tool connections. There are many different
types of flex hose on the market today. These are
manufactured from materials such as polyethyl-
ene, PVC, cloth hose dipped in rubber and even
metal, including steel and aluminum.
The Model G1028Z/G1029 can be operated as
either a stationary or a mobile unit. There are
advantages and disadvantages to both set-ups.
The advantage of the mobile system is eliminat-
ing the cost of many ducts and fittings. On the
other hand, the stationary system is more versa-
tile and convenient.
The Model G1028Z/G1029 is designed to be a
central dust collector system. Locate the dust col-
lector in an out of the way location such as a cor-
ner or separate room. The dust collector is capa-
ble of collecting dust from up to two machines
running simultaneously. Because of the large
suction capacity of the Model G1028Z/G1029,
great flexibility is possible in the planning and
designing of your dust collection duct layout.
Grizzly offers a complete line of dust collection
accessories for setting up a stationary system.
Additionally, Grizzly offers a complete guide book
entitled Dust Collection Basics.
Whatever system you choose, 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 dust is dispursed into the air.
SECTION 5: Designing The System

-16- G1028Z/G1029 Dust Collector
Since plastic hose is abundant, relatively inexpen-
sive, easily assembled and air tight, it is a very
popular material for conveying dust from wood-
working machines to the dust collector. We rec-
ommend using flexible hose (flex-hose) to con-
nect the woodworking machine to the dust collec-
tor. However, plastic flex-hose and plastic duct
are an insulator, and dust particles moving
against the walls of the plastic duct create a stat-
ic electrical build up. This charge will build until it
discharges to a ground. If a grounding medium is
not available to prevent static electrical build up,
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 build up 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 con-
firm that the dust collector is continuously ground-
ed through the electrical circuit to the electric ser-
vice 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 recom-
mend inserting a continuous bare copper ground
wire inside the entire duct system and attaching
the wire to each grounded woodworking machine
and dust collector.
System Grounding
Always guard against
static electrical build up
by grounding all dust
collection lines.
There are also many kinds of pure plastic flexible
hose, such as non-perforated drainage type hose
and dryer vent hose. Drainage type hose, while
being economical, does not quite have the flexi-
bility required for dust collection. The inside of the
duct is also deeply corrugated and can increase
the static pressure loss by as much as 50% over
smooth wall duct. Dryer vent hose, while being
completely flexible, is non-resistant to abrasion
and has a tendency to collapse in a negative
pressure system.
If using flex-hose, you should choose one of the
many types that are designed specifically for the
movement of solid particles, i.e. dust, grains and
plastics. However, the cost of specifically
designed flexible duct can vary greatly. Grizzly
offers polyethylene hose which is well suited for
the removal of particulate matter, especially saw-
dust, since it is durable and completely flexible.
Polyethylene is also very economical and avail-
able in a wide variety of diameters and lengths for
most applications.
PLASTIC DUCT
The popularity of plastic duct is due to the fact that
it is an economical and readily available product.
It is also simple to assemble and easily sealed
against air loss. The primary disadvantage of
plastic duct for dust collection, whether black ABS
or white PVC and even rubber or polyethylene
flex-hose, is the inherent danger of static electri-
cal build-up.

G1028Z/G1029 Dust Collector -17-
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” connec-
tion.
Ensure that the entire system is grounded. If
using plastic blast gates to direct air flow, the
grounding wire must be jumped (Figure 12)
around the blast gate without interruption to the
grounding system.

The best way to plan your new system is to draw
a bird’s eye view (as shown in Figure 14)of your
shop and sketch the following:
1. Your desired location of the dust collector,
usually in a corner or along a wall.
2. The location of each machine in the system.
3. The location of the main line duct and each
branch line.
4. The location of any obtrusion such as a joist
or heating duct, that will require special duct
routing.

When designing a successful dust collection sys-
tem, planning is the most important step. Before
you set out to run the first section of duct, consid-
er these general guidelines for an efficient sys-
tem:
1. Machines that produce the most saw dust
should be placed nearest to the dust collec-
tor. These machines include thickness plan-
ers, shapers, sanders and bandsaws.
2. Ideally, you should design the duct system to
have the shortest possible mainline run and
to have short secondary branch ducts.
3. Directional changes should be kept to a min-
imum. The more directional change fittings
you use, the greater the loss of overall pres-
sure.
4. Gradual directional changes are more effi-
cient than sudden directional changes (i.e.
use the largest corner radius possible when
changing hose or pipe direction).
5. Each individual machine should have a blast
gate to control suction from one machine to
another.
6. The simpler the system, the more efficient
and less costly it will be.
