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 filter
out microscopic particles.

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 avoid
accidental slips, which could cause loss of work­piece control.

HAZARDOUS DUST. Dust 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 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.

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.

CHECK DAMAGED PARTS. Regularly inspect
machine for any condition that may affect safe
operation. Immediately repair or replace damaged
or mis-adjusted parts before operating machine.

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.

GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly.

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

Model G0671/G0672/G0673 (Mfg. Since 1/13

Additional Safety for Dust Collectors

1. MACHINE USE. This machine only is

intended to collect wood dust/chips from
woodworking machines. Do not use this
dust collector as a vacuum. Do not use
this dust collector with machines producing
dust/chips from metal, asbestos products,
lead paint, silica or any products that are
not natural wood or man-made wood prod­ucts such as plywood or particle board.

2. WEAR RESPIRATOR. This machine may

blow fine dust particles into the air dur­ing operation. Always wear an approved
respirator during and for a short time after
machine operation!

3. SUSPENDED DUST PARTICLES AND
IGNITION SOURCES. 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 or
open flames.

4. EMPTYING DUST. When emptying dust
from the collection bags or drum, wear a

respirator and safety glasses. Empty dust
into an approved container and dispose of
properly.

5. SAFE SERVICING. Disconnect power and
allow impeller to completely stop before
servicing or working on the dust collector
or the ducting system, especially if clearing
a clogged duct.

6. AVOIDING FIRES. Do not allow steel to

strike against the impeller—this may pro­duce a spark. Sparks can smolder in wood
dust for a long time before fire or flame is
detected. If you accidentally collect metal
during operation, immediately turn off the
dust collector, 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. Prevent
any chance of accidentally collecting metal
again before resuming operations.

7. KEEPING FINGERS SAFE. Do not place

your hands or tools near the open inlet dur­ing operation for any reason. The powerful
suction could cause accidental contact with
the impeller which will cause serious per­sonal injury or damage to the machine.

8. OPERATIONAL QUESTIONS. If at any

time you are experiencing difficulties
performing the intended operation, stop
using the machine! Then contact our Tech
Support or ask a qualified expert how the
operation should be performed.

9. DUST HAZARD. 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.

Like all machines there is danger associated
with this machine. Accidents are frequently
caused by lack of familiarity or failure to pay
attention. Use this machine with respect
and caution to lessen the possibility of
operator injury. If normal safety precautions
are overlooked or ignored, serious personal
injury may occur.

Model G0671/G0672/G0673 (Mfg. Since 1/13

No list of safety guidelines can be complete.
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 do so could result in serious per­sonal injury, damage to equipment, or poor
work results.

Test Run

5. Listen to and watch for abnormal noises or

actions. The machine should run smoothly
with little or no vibration or rubbing noises.

Once the assembly is complete, test run your
machine to make sure it runs properly and is
ready for regular operation.

The test run consists of verifying the following: 1)
The motor powers up and runs correctly, and 2)
(Model G0673 only), the motor turns the correct
direction (machine is not wired out of phase).

If, during the test run, you cannot easily locate
the source of an unusual noise or vibration, stop
using the machine immediately, then review the
Troubleshooting on Page 38.

If you still cannot remedy a problem, contact our
Tech Support at [phone] for assistance.

Before starting the dust collector, make
sure you have performed the preceding
assembly instructions, and you have read
through the rest of the manual and are
familiar with the various functions and
safety features on this machine. Failure to
follow this warning could result in serious
personal injury or even death!

— Strange or unusual noises should be inves-

tigated and corrected before operating the
machine further. Always disconnect the
machine from power when investigating or
correcting potential problems.

6. Turn the machine OFF by pushing in the RED

button on the power switch.

7. Model G0673 Only: Verify that the power

is not connected out of phase by starting/
stopping the machine and determining if the
motor turns in the correct direction, using the
criteria below:

— If the impeller turns counterclockwise

(when looking down on the inlet port on the
impeller housing), it is turning in the correct
direction.

— If the impeller turns clockwise, it is turning

in the wrong direction. Stop the machine,
shut off the power source, then swap any
two of the three power wires that connect
to the machine.

To test run the machine:

1. Make sure you have read the safety instruc-

tions at the beginning of the manual and that
the machine is setup properly.

2. Make sure all tools and objects used during

setup are cleared away from the machine.

3. Connect the machine to the power source.

4. Turn the machine ON by pushing in the

GREEN button on the power switch.

SECTION 4: DESIGNING THE

SYSTEM

General

The Model G0671/G0672/G0673 can be operated
as either a stationary or mobile unit. There are
advantages and disadvantages to both set-ups.
The advantage of the mobile system is eliminating
the cost of many ducts and fittings. On the other
hand, the stationary system is more versatile and
convenient.

The Model G0671/G0672/G0673 is designed to
be a central dust collector system. Locate the dust
collector in an out of the way location such as a
corner or separate room. These machines can
accommodate the following number of machines
each drawing 400 CFM on a 4" dust port:

G0671: ............................................................... 8

G0672: ............................................................... 9

G0673: ............................................................. 12

The large suction capacity of the Model G0671/
G0672/G0673 allows great flexibility in 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
titled Dust Collection Basics.

Duct Material

You have many choices regarding main line and
branch line duct material. For best results, use
metal duct for the main line and branch lines, then
use short lengths of flexible hose to connect each
machine to the branch lines.

Plastic duct is also a popular material for home
shops. However, 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 this section. Another problem
with using plastic is that it is less efficient per foot
than metal.

Metal Duct

Advantages of metal duct (Figure 20) 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 conductor, it can
be grounded quite easily to dissipate any static
electrical charges.

A 4-port inlet is included with the Model G0671/
G0672 and a 5-port inlet is included with the
Model G0673 for quick and economical dust col­lection setup. However, depending upon your
system design using this feature, bags may fill at
different rates requiring you to empty some bags
more often than others.

Whatever system you choose, always make sure
there are no open flames (including pilot lights) in
the same room as the dust collector; otherwise
you risk an explosion if dust is dispersed into the
air.

There are quite a number of options when it
comes to metal duct, but metal duct that is spe­cially manufactured for 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 machines. See
the Accessories section on Page 35 for exam­ples.

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.

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 flex­ibility 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 offers greater
flexibility, but is non-resistant to abrasion and
tends to collapse in a negative pressure system.
We DO NOT recommend using dryer vent hose in
your dust collection system.

If using flex-hose, choose one of the many types
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 sawdust, since it is durable and
completely flexible. Polyethylene is also very eco­nomical and available in a wide variety of diam­eters and lengths for most applications.

Flexible Duct

Flexible 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 polyethylene, PVC, cloth hose
dipped in rubber and even metal, including steel
and aluminum.

The superior choice for flexible ducting is metal
flex hose that is designed to be flexible and as
smooth as possible to reduce static pressure loss.

Plastic Duct

The popularity of plastic duct is due to the fact
that it is economical and readily available. It is
also simple to assemble and easily sealed against
air loss. The primary disadvantage of plastic duct
for dust collection is the inherent danger of static
electrical build-up.

System Design

Step 1. Decide Who Will Design

For most small-to-medium sized shops, you can
design and build the dust collection system your­self without hiring engineers or consultants. We
have included some basic information here to get
you started on a dust collection system design.

If you have a large shop or must design a com­plicated system, then we recommend that you
perform additional research beyond this manual,
or seek help from an expert.

Step 2. Sketch Your Shop Layout

Planning is the most important step when design­ing a successful dust collection system.

Before you begin to draw your necessary layout
sketch, we recommend that you visit our FREE
Workshop Planner available on our website at
www.grizzly.com.

Our Workshop Planner will allow you to quickly
and easily draw and print a basic shop layout.
Don't worry, non-Grizzly brand machines can be
substituted with Grizzly machines for layout pur­poses. Note: After you're finished, make sure to

save your layout for later modification.

Step 3. Sketch a Basic Duct Layout

For the next step, sketch how your machines will
connect to the dust collector. Consider these gen­eral guidelines for planning an efficient system:

1. Machines that produce the most sawdust

should be placed nearest to the dust collector
(i.e. planers and sanders).

2. Ideally, you should design the duct system

to have the shortest possible main line and
secondary branch ducts. See Figures 24 &
25 for ideas of good duct layouts vs bad duct
layouts.

Line Ducts

Your sketch only needs the basic details of the

your current/planned machines and your planned
placement of the dust collector.

3. Directional changes should be kept to a mini-

mum. The more directional change fittings
you use directly increases the overall resis­tance to airflow.

If your machine does not have a built in dust port,
use Figure 27 to determine the size of dust port
to install on your machine.

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 branch line should have a blast gate

immediately after the branch to control suc­tion from one machine to another.

6. The simpler the system, the more efficient

and less costly it will be.

Step 4. Determine Required CFM of
Each Machine

Since each machine produces a different amount
of sawdust, the requirements for the minimum
amount of CFM needed to move that sawdust is
unique to the machine (for example, a planer pro­duces more sawdust than a table saw). Knowing
this required CFM is important in gauging which
size of duct to use.

Figure 26 will give you a close estimation of the
airflow your machine requires. Machines that
generate the most sawdust should be placed near
the dust collector. If the machine has multiple
dust ports, the total CFM required is the sum of
all ports.

Use the inlet size of the dust collector as a starting
point for the main line. Neck the main line down
1" for every 10' of length. This will usually keep
the air velocity above 3500 FPM and, depending
on your system, will allow you to keep multiple
branches open at one time.

Multiple Dust Ports

If your machine has multiple dust ports, add the
total CFM given for each dust port size from
Figure 26. Refer to Figure 31 and find the CFM
that is closest to your total to determine the cor­rect branch size. Split the branch line just before
the dust ports with matching duct sizes.

Two Machines on Same Branch Line

If both machines will be running at the same time,
add the total CFM given for each dust port size
from Figure 26.

Figure 29. Main line size labeled on sketch.

Determining Branch Line Duct Size

The general rule of thumb for a branch line duct is
that the velocity of the airflow must not fall below
4000 FPM.

For small/medium sized shops, using the dust
port size from the machine as the branch line duct
size will achieve the correct velocity in most appli­cations. However, if the dust port on the machine
is smaller than 4", make the branch line 4" and
reduce the line right before the dust port.

Note: Systems with powerful dust collectors work
better if multiple blast gates are left open. This
also allows you to run two machines at once.
Experiment with different combinations of blast
gates open/closed to find the best results for your
system.

Write your determined branch line sizes on your
drawing, as shown in Figure 30.

If both the machines will never be run at the same
time, reference the machine with biggest dust
port to Figure 31 and add blast gates after the
Y-branch to open/close the line to each machine.

Calculating Duct Resistance

Adding duct work, elbows, branches and any
other components to a duct line increases airflow
resistance (static pressure loss). This resistance
can be minimized by using rigid (smooth) pipe and
gradual curves, as opposed to flexible pipe and
90˚ elbows.

To help you think about this resistance, imagine
riding a bicycle in a tunnel that is an exact replica
of your duct work. If the inside of the tunnel is very
bumpy (flexible pipe) and has many sharp turns
(90˚ elbows), it will take a lot more effort for you to
travel from one end to the other than if your path
is smooth and straight.

The purpose of calculating this resistance is to
determine if it is low enough from the machine to
the dust collector to meet the given requirement
for the machine. Use the charts in Figure 32 to
calculate the resistance of duct work.

In most small/medium shops it is only necessary
to calculate FPM for the line (from the dust collec­tor to the machine) with the longest duct length or
the most fittings (operating under the assumption
that if the line with the highest resistance works,
the others will be fine).

The line with the longest duct length and most fit­tings in our system sketch (see Figure 30) is the
one connected to the router table, which draws
220 CFM.

To calculate the static pressure loss of any
given line in the system, follow these steps:

1. Make a list of each size duct in the line,

including the length, and multiply those num­bers by the static pressure loss value given in

Figure 32.

2. List each type of elbow or branch and multiply

the quantity (if more than one) by the static
pressure loss given in Figure 32.

3. Add the additional factors from Figure 33 to

your list.

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 using flexible hose (flex-hose) to con­nect the woodworking machine to the dust collec­tion system. However, plastic flex-hose and plastic
duct are insulators, and dust particles moving
against the walls of the plastic duct create static
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.

Ensure that the entire system is grounded. If using
plastic blast gates to direct air flow, the grounding
wire must be jumped (Figure 36) around the
blast gate without interruption to the grounding
system.

Plastic

Blast
Gate

Copper

Ground

Wire

Metal Duct

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
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.

We also recommend wrapping the outside of all
plastic ducts with bare copper wire to ground the
outside of the system against static electrical build

made with wire nuts.

Ground Screw

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

General

Operating your Model G0671/G0672/G0673 is
simple and straightforward. Blast gates located
at each of the woodworking machines control the
airflow from the woodworking machine to the dust
collector. If a machine is not being used, keep
the blast gate closed to maintain higher levels of
efficiency throughout the system.

DO NOT use the dust collector for any
other purpose besides collecting dust from
connected woodworking machines. A dust
collector should NEVER be used as a shop
vacuum. For safest use, wear a respirator
and use an air cleaner in addition to the
dust collector.

SECTION 7: MAINTENANCE

Disconnect power to the
machine when perform­ing any maintenance,
assembly or adjustments.
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.

Schedule

For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.

Daily Check:

• Dust collector is completely powered down at
the end of use.

• Loose mounting bolts.

• Worn switch or wires.

• Any other condition that would hamper the
safe operation of this machine.

• Empty the lower collection bags before they
become completely full.

Bag Cleaning

All dust collectors dis­perse fine dust which may
cause allergic reactions
or respiratory problems.
Always wear a respirator
when operating your dust
collector.

Empty the lower collection bags on a regular
basis to maintain dust collection efficiency.

Always wear the appropriate respirator or dust
mask and safety glasses when emptying the col­lection bags. Small dust particles can escape the
bags during emptying, causing them to become
airborne and easily inhaled. This microscopic air­borne dust is extremely unhealthy to breathe and
can cause serious health problems.

While the Model G0671/G0672/G0673 excels at
collecting the majority of wood dust produced
by your machines, we always recommend the
supplemental aid of a shop air filter. Air filters are
designed to collect the smaller airborne dust par­ticles that a dust collector bags cannot trap.

Lubrication

Since all bearings are shielded and permanently
lubricated, simply leave them alone until they
need to be replaced. Do not lubricate them.

Dust Collection Operation

SYMPTOM POSSIBLE CAUSE CORRECTIVE ACTION

Loud, repetitious noise, or
excessive vibration coming
from dust collector.

Dust collector does not
adequately collect dust or
chips; poor performance.

Sawdust being blown
into the air from the dust
collector.

1. Dust collector is not on a flat
surface and wobbles.

2. Impeller fan is damaged and
unbalanced.

3. The motor mounting is loose.

4. Impeller is loose on the motor
shaft.

5. Motor fan cover is dented, causing
the motor fan to hit the cover while
spinning.

1. Dust collection bag is full/filter bag
is dir t y.

2. There is a restriction in the duct
line.

3. The dust collector is too far away
from the point of suction, or there
are too many sharp bends in the
ducting.

4. The lumber is wet and not flowing
through the dust lines smoothly.

5. There is a leak in the ducting, or a
series of small leaks, or too many
open ports.

6. There are not enough open branch
lines at one time, thereby causing
a velocity drop in the main line.

7. The ducting and ports are
incorrectly sized.

8. The machine dust collection
design is inadequate.

9. The dust collector is too small for
the dust collection system.

1. Bag clamps, dust collection
bag, or filter bag is not properly
secured.

1. Stabilize the dust collector.

2. Unplug dust collector, and inspect the impeller for
dents, bends, loose fins. Replace impeller if any
damage is found.

3. Make sure all fasteners on the dust collector are
tight.

4. Replace the motor and impeller as a set if the
motor shaft and the impeller hub is damaged.

5. Replace motor fan cover.

1. Empty collection bag/clean or replace filter bag.

2. Remove dust line from dust collector inlet and
unblock the restriction in the duct line. A plumbing
snake may be necessary.

3. Relocate the dust collector closer to the point of
suction, and rework ducting without sharp bends.
Refer to Designing the System, beginning on
Page 26.

4. Process lumber with less than 20% moisture
content.

5. Rework the ducting to eliminate all leaks. Close
dust ports for lines not being used. Refer to
Designing the System on Page 26 for more
solutions.

6. Open 1 or 2 more blast gates to different branch
lines to allow the velocity in the main line to
increase.

7. Reinstall correctly sized ducts and fittings. Refer
to Designing the System on Page 26 for more
solutions.

8. Use a dust collection nozzle on a stand.

9. Install a larger dust collector to power your dust
collection system.

1. Reclamp the dust collection bag and air filter bag,
making sure bag clamps are tight and completely
over the bags.

Wiring

SECTION 9: WIRING

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. 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.

Wiring Safety Instructions

1. SHOCK HAZARD. Working on wiring that

is connected 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!

2. QUALIFIED ELECTRICIAN. Due to the

inherent hazards of electricity, only a quali­fied electrician should perform wiring tasks
on this machine. If you are not a quali­fied electrician, get help from one before
attempting any kind of wiring job.

3. 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.

4. 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 before completing the task.

5. MODIFICATIONS. Using aftermarket parts or

modifying the wiring beyond what is shown
in the diagram may lead to unpredictable
results, including serious injury or fire.

6. MOTOR WIRING. The motor wiring shown

in these diagrams is current at the time of
printing, but it may not match your machine.
Always use the wiring diagram inside the
motor junction box.

7. CAPACITORS. Some capacitors store an

electrical charge for up to five minutes after
being disconnected from the power source.
To avoid being shocked, wait at least this
long before working on capacitors.

8. CIRCUIT REQUIREMENTS. You MUST fol-
low the requirements on Page 16 when con­necting your machine to a power source.

9. EXPERIENCING DIFFICULTIES. If you are
experiencing difficulties understanding the
information included in this section, contact
our Technical Support at [phone].
