The mill/drill is used to shape metal and solid
workpieces by removing material with the use of
a rotating cutting tool.
In milling operations, the cutting tool remains sta-
tionary while the workpiece is drawn across it by
moving the table.
In drilling operations, the workpiece is held sta-
tionary on the table while the cutting tool moves
up-and-down with the movement of the spindle
and head.

Additional Safety for Mill/Drills
UNDERSTANDING CONTROLS. Make sure you
understand the use and operation of all controls.
SAFETY ACCESSORIES. Always use a chip
guard in addition to your safety glasses when mill-
ing/drilling to prevent bodily injury.
WORK HOLDING. Before starting the machine,
be certain the workpiece has been properly
clamped to the table. NEVER hold the workpiece
by hand when using the mill/drill.
CHUCK KEY SAFETY. Always remove your
chuck key, drawbar wrench, and any service tools
immediately after use.
SPINDLE SPEEDS. Select the spindle speed
that is appropriate for the type of work and mate-
rial. Allow the mill/drill to gain full speed before
beginning a cut.
POWER DISRUPTION. In the event of a local
power outage during use of the mill, drill turn OFF
all switches to avoid possible sudden start up
once power is restored.
SPINDLE DIRECTION CHANGES. Never reverse
spindle direction while the spindle is turning.
MACHINE CARE AND MAINTENANCE. Never
operate the mill/drill with damaged or worn parts.
Maintain your mill/drill in proper working condition.
Perform routine inspections and maintenance
promptly. Put away adjustment tools after use.
STOPPING SPINDLE. DO NOT stop the mill/drill
using your hand against the chuck.
BE ATTENTIVE. DO NOT leave the mill/drill run-
ning unattended for any reason.
DISCONNECT POWER. Make sure the mill/drill is
turned OFF, disconnected from its power source
and all moving parts have come to a complete
stop before starting any inspection, adjustment,
or maintenance procedure.
AVOIDING ENTANGLEMENT. Keep loose cloth-
ing articles such as sleeves, belts or jewelry items
away from the spindle. Never wear gloves when
operating the mill/drill.
TOOL HOLDING. Always use the proper tools
for the material you are machining. Make sure
they are held firmly in the proper tool holder for
the job.
CLE AN - U P. DO NOT clear chips by hand. Use a
brush, and never clear chips while the spindle is
turning.
CUTTING TOOL INSPECTION. Inspect drills and
end mills for sharpness, chips, or cracks before
each use. Replace dull, chipped, or cracked cut-
ting tools immediately. Handle new cutting tools
with care. Leading edges are very sharp and can
cause lacerations.
EXPERIENCING DIFFICULTIES. If at any time
you are experiencing difficulties performing the
intended operation, stop using the machine!
Contact our Technical Support at (570) 546-
9663.
No list of safety guidelines can be complete. Every shop environment is different. Like all
machines there is danger associated with the Model G0704. 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 G0704 (Mfg. Since 0 8/11)-11-
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 electrican or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the 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 ..... 3.2 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 requirements in the following section.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Circuit Requirements
Note: The circuit requirements listed in this man-
ual apply to a dedicated circuit—where only one
machine will be running at a time. If this machine
will be connected to a shared circuit where mul-
tiple machines will be running at the same time,
consult a qualified electrician to ensure that the
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 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.)
This machine is prewired to operate on a 110V
power supply circuit that has a verified ground and
meets the following requirements:
Nominal Voltage ............................... 110V/120V
Cycle ..........................................................60 Hz
Phase ........................................... Single-Phase
Power Supply Circuit ......................... 15 Amps
-12- Model G0704 (Mfg. Since 0 8/11)
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 may
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
contain a ground wire, match the required plug
and receptacle, and meet the following require-
ments:
Minimum Gauge Size ...........................16 AWG
Maximum Length (Shorter is Better).......50 ft.

Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.
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.
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 ground-
ing plug (similar to the figure below). The plug
must only be inserted into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.

ing or they are pre-installed at the factory.
Model G0704 (Mfg. Since 0 8/11)-15-
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
There are many ways to remove this rust preven
-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac
-
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
•
Disposable Rags
•
Cleaner/degreaser (WD•40 works well)
•
Safety glasses & disposable gloves
•
Plastic paint scraper (optional)
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
Gasoline or products
with low flash points can
explode or cause fire if
used to clean machin-
ery. Avoid cleaning with
these products.
Many cleaning solvents
are toxic if concentrat-
ed amounts are inhaled.
Only work in a well-venti-
lated area.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces. Test all cleaners
in an inconspicuous area before using to
make sure they will not damage paint.

Site Considerations
Figure 6. Space required for full machine range of motion.
Weight Load
Refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work-
piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main-
tenance and service described in this manual.
See below for required space allocation.
Physical Environment
The physical environment where the machine is
operated is important for safe operation and lon-
gevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemi-
cals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.
Electrical Installation
Place this machine near an existing power source.
Make sure all power cords are protected from
traffic, material handling, moisture, chemicals,
or other hazards. Make sure to leave access to
a means of disconnecting the power source or
engaging a lockout/tagout device, if required.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

To remove your machine from the shipping
crate and place it in position:
1. Place the crate adjacent to the location where
your machine will be placed, then remove the
shipping crate from the pallet.
2. Position the stand into the desired location.
3. Use the vertical handwheel to raise the head-
stock as far as possible.
4. Hang a lifting strap from the fork of a forklift
and place it under the head of the mill/drill, as
shown in Figure 7. Take care not to place the
straps over any controls that may be dam-
aged during transit.
Figure 7. Lifting strap.
Moving & Placing
Machine
The Model G0704 is a
heavy machine. Serious
personal injury may occur
if safe moving methods
are not used. To be safe,
get assistance and use
power equipment to move
the shipping crate and
remove the machine from
the crate.
5. Unbolt the machine from the pallet, then with
an assistant steadying the machine to pre-
vent it from swinging, lift it slightly off of the
pallet. Use the cross handwheel to move the
table forward or backward as necessary to
balance the machine so it hangs as close to
level as possible.
6. Lift the machine and carefully place it onto
the stand.
7. Bolt the machine to the stand with the four
M10-1.25 x 50 hex bolts and flat washers.
—If you are placing the machine on a work-
bench, it must be securely mounted to the
workbench surface.
The strongest mounting option is a "Through
Mount" where holes are drilled all the way
through the workbench, and hex bolts, wash-
ers, and hex nuts are used to secure the
machine to the workbench.

Although not required, we recommend that you
mount your new machine cabinet to the floor.
Because this is an optional step and floor mate-
rials may vary, floor mounting hardware is not
included. Generally, you can either bolt the cabi-
net to the floor or mount it on machine mounts.
Both options are described below. Whichever
option you choose, it is necessary to level the
cabinet with a precision level.
Bolting to Concrete Floors
Lag shield anchors with lag bolts and anchor
studs (Figure 10) are two popular methods for
anchoring an object to a concrete floor. We sug-
gest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application.
Mounting to Shop
Floor
Figure 10. Typical fasteners for mounting to
concrete floors.
NOTICE
Anchor studs are stronger and more per-
manent alternatives to lag shield anchors;
however, they will stick out of the floor,
which may cause a tripping hazard if you
decide to move your machine.
Figure 11. Machine mount example.
Using Machine Mounts
Using machine mounts, shown in Figure 11, gives
the advantage of fast leveling and vibration reduc-
tion. The large size of the foot pads distributes
the weight of the machine to reduce strain on the
floor.
NOTICE
We strongly recommend securing your
machine to the floor if it is hardwired to the
power source. Consult with your electrician
to ensure compliance with local codes.

Assembly
Assembly of the Model G0704 consists of attach-
ing the four handwheel handles to the machine.
To assemble your machine:
1. With a #3 standard screwdriver, install the
large handwheel handle on the elevation
handwheel (Figure 12).
2. Use the same method to install the three
small handwheel handles to the three table

Your machine includes an B-16 drill chuck arbor
and drill chuck. Before use, the drill chuck must
be installed onto the arbor. The This drill chuck
installation is intended to be semi-permanent.
Tip: For a permanent installation, chill the arbor
in the freezer for 15 minutes before performing the
following procedure. The taper will expand as it
returns to room temperature, permanently locking
the chuck.
To install the drill chuck onto the arbor:
1. Clean the grease off the drill chuck and all
taper mating surfaces. Pay particular atten-
tion to the B-16 bore in the drill chuck—it
must be free from all grease, oil, and debris.
2. Retract the drill chuck jaws fully by turning the
body of the drill chuck counterclockwise.
3. Insert the arbor into the drill chuck. Tap the
arbor lightly with a brass or other soft-headed
hammer to get a good fit.
Note: While it may not seem like there is
anything keeping the drill chuck in place, the
B-16 Taper fit provides a strong bond and will
hold the drill chuck tightly (Figure 14).

Calculating Spindle
Speed
Closely follow the proper spindle speed and
proper feed rate to produce good results, reduce
undue strain on all moving parts and increase
operator safety.
Prior to milling, determine the spindle speed
needed to cut your workpiece, then set the speed
on the machine.
To determine the needed spindle speed:
1. Use the table in Figure 24 to determine the
cutting speed required for the material of your
workpiece.
2. Measure the diameter of your cutting tool in
inches.
3. Use the following formula to determine the
needed spindle RPM for your operation:
(Cutting Speed x 4) /Tool Diameter = RPM
Cutting Speeds for High Speed Steel (HSS)

Model G0704 (Mfg. Since 0 8/11)-27-
Spindle Speed and
Direction
Setting the speed on the Model G0704 is a two
part process. The gearbox in the headstock has
two gear ranges and the motor is a variable speed
unit. Together, these two systems provide an
overall speed range of 50–2250 RPM.
When the dial is turned up all the way, the motor
draws the full amperage level. When combined
with a cutting load, the motor can overheat and
become damaged. If high speeds are needed, put
the speed range into high "H" then turn the vari-
able speed dial down, away from the maximum
position. If the maximum RPM is needed, reduce
the cutting load as much as possible and mini-
mize the operation time at these speeds.
To set the spindle speed:
1. Determine the appropriate spindle speed for
your operation. See Calculating Spindle
Speed on Page 26.
2. Select the appropriate speed range using
the speed range selector knob (Figure 25).
"H" represents the high speed range, which
is capable of spindle speeds from 100–2250
RPM. "L" represents the low range, which
is capable of spindle speeds from 50–1125
RPM.
Note: To maximize spindle torque, use the
low range.
Note: It may be necessary to rotate the
spindle by hand to get the gears to mesh
properly.
3. Make sure the work area is clear and that all
safety precautions are taken.

Changing Spindle Position Using
Fine Feed Knob
1. Unlock the quill lock lever and tighten the fine
feed lock knob.
2. Rotate the fine feed knob to lower or raise
the spindle in small increments. Observe the
scale on the knob or the digital readout to
monitor movement in thousandths of an inch
(Figure 28).
3. Tighten the quill lock lever to hold the spindle
in a particular position if you choose.
Tip: Milling with the spindle fully extended
can cause tool chatter. For maximum spindle
rigidity when milling, it is better to keep the
spindle retracted into the headstock as far
as possible with the quill lock lever tightened,
and the fine feed knob tightened.

Drill Chuck
Figure 29. Tightening the drawbar.
5. Hold the chuck with one hand and finish loos-
ening the drawbar until the chuck falls out of
the spindle.
Note: The chuck is attached to the arbor
using a B-16 taper. This attachment is con-
sidered to be semi-permanent. There should
be no need to remove the chuck from the
arbor.
4. Use the included spindle pin to prevent the
spindle from turning while you use an 8mm
wrench to loosen the drawbar 2–3 turns. DO
NOT continue loosening the drawbar without
supporting the drill chuck or it will fall from the
spindle.
To remove the chuck and arbor from the
spindle:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Remove the drawbar cap.
3. Lock the quill in place with the quill lock
lever.
To install the drill chuck and arbor:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Remove the drawbar cap.
3. Insert the chuck arbor into the spindle, mak-
ing sure to line up the slot in the arbor with
the pin in the spindle.
4. Thread the drawbar into the arbor until the
arbor is seated up into the spindle taper.
5. Use the included spindle pin to prevent the
spindle from turning while you use an 8mm
wrench to tighten the drawbar.
NOTICE
The Model G0704 drawbar will extract the
arbor from the spindle. Once the arbor or
collet has broken free from the spindle
taper, be sure to properly support it while
continuing to loosen the drawbar. Failure
to properly support the arbor or collet
while loosening the drawbar will result in
the arbor or collet falling out of the spindle,
causing damage to machine components.
Note: Do not overtighten the drawbar.
Overtightening makes arbor removal difficult
and will damage the arbor and threads.
6. Re-install the drawbar cap.
Drawbar
Spindle Pin
-30- Model G0704 (Mfg. Since 0 8/11)
Your Model G0704 features an R-8 spindle taper,
which gives the freedom to use standard R-8
cutting tools and collets. These optional collets
come in many sizes, typically ranging from 1⁄16" to
7⁄8" and 3mm to 20mm, and should be matched to
your cutting tool shank size.
To install the tooling:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Remove the drawbar cap.
3. Carefully clean the surface of the tooling and
spindle taper. Ensure that it is free of debris
and is lightly oiled.
4. If you are using a cutting tool and collet, insert
the cutting tool into the collet, then insert the
collet up into the spindle taper, making sure
the slot in the collet lines up with the pin in the
spindle.
If you are using a cutting tool that installs
directly into the spindle, insert the tool into the
spindle taper, making sure the slot in the tool
lines up with the pin in the spindle.
5. Slide the tooling upward until it makes con-
tact with the drawbar threads.
6. Hand thread the drawbar into the tooling until
the tooling draws up into the spindle taper.
7. Use the included spindle pin to prevent the
spindle from turning while you use an 8mm
wrench to tighten the drawbar.
Note: Do not overtighten the drawbar.
Overtightening makes collet removal difficult
and will damage the drawbar threads, collet,
and the spindle taper. Keep in mind that the
taper keeps the collet and tool in place. The
drawbar simply aids in seating the taper.
Loading Tooling To remove the collet:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Remove the drawbar cap.
3. Lock the quill in place with the quill lock
lever.
4. Use the included spindle pin to prevent the
spindle from turning while you use an 8mm
wrench to loosen the drawbar 2–3 turns. DO
NOT continue loosening the drawbar without
supporting the collet or it will fall from the
spindle.
LACERATION HAZARD!
Leading edges of end mills
and other cutting tools can
be very sharp. Protect your
hands with gloves or a shop
towel when handling.
5. Protect the table surface with a piece of
cardboard and hold the cutter/tool with a
shop towel to prevent it from falling out of the
collet. Continue loosening the drawbar until
the collet is freed from the spindle.
NOTICE
The Model G0704 drawbar will extract the
arbor from the spindle. Once the arbor or
collet has broken free from the spindle
taper, be sure to properly support it while
continuing to loosen the drawbar. Failure
to properly support the arbor or collet
while loosening the drawbar will result in
the arbor or collet falling out of the spindle,
causing damage to machine components.

Table Travel
The mill/drill table can be moved in the longitudi-
nal (X-axis) and cross (Y-axis) directions.
Longitudinal Feed
The X-axis is moved by the handwheels shown
in Figure 32 at the end of the table. These
handwheels will move the table in both directions
side-to-side. One complete revolution of either
handwheel moves the longitudinal feed 0.100".
There is also a scale on the front of the table for
use when a tight tolerance is not required. The
longitudinal feed can be locked in position by
table locks located on the front of the table (see
Figure 33).
Cross Feed
The Y-axis shown in Figure 32, is moved with the
handwheel on the front of the table base. One
complete revolution of the handwheel moves the
cross slide 0.100". The cross feed can be locked
into position by a table lock lever located on the
right side of the cross slide underneath the table
(see Figure 33).

Gibs are wedge-shaped pieces of metal that
fill the gap between the sliding surfaces of the
machine. By adjusting the position of the gib in
its gap, you can remove any play that might exist
between the adjacent components. The gibs are
pre-adjusted at the factory but due to storage,
break-in, and usage, may require adjustment. If
movement seems too tight at first, make sure that
all the rust preventative that was shipped on the
machine is removed from the ways. Lubricate the
ways with oil, and work the table back-and-forth
several times until the movement is easier.
To adjust the table gibs:
1. DISCONNECT MILL/DRILL FROM POWER!
2. Loosen the table travel locks (Figure 55).

Leadscrew Backlash
Digital Readout Unit
Battery Replacement
When you turn the handwheels to adjust the posi-
tion of the table, you will notice slight play (back-
lash) in the handwheel before the table begins to
move. If this play is greater than 0.008" (measured
with the dial at the base of each handwheel), then
you will need to adjust the leadscrew nuts.
To reach the adjustment screws on the leadscrew
nut, you may have to fabricate extensions for
your hex wrenches. When adjusting, make adjust-
ments in small increments. Attempting to reduce
backlash to less than 0.003" is impractical and
will add unnecessary wear to both the leadscrews
and the leadscrew nuts.
To adjust the X-axis leadscrew:
1. Locate the X-axis leadscrew nut under the
middle of the table. The head on the adjust-
ment screws face to the right (Figure 57).
To adjust the Y-axis leadscrew nut:
1. Locate the leadscrew nut underneath the
table through the hole in the base under the
rubber way cover.
2. Tighten the adjustment screws on the
leadscrew nut in the same manner as
described for the X-axis leadscrew adjust-
ment.
3. Test the adjustment by turning one of the
cross handwheels. The ideal amount of play
when properly adjusted is 0.003"–0.006".
2. Tighten the adjustment screws.
3. Test the adjustment by turning one of the
longitudinal handwheels. The ideal amount
of play when properly adjusted is 0.003"–
0.006".

Motor Service
The bearings inside the motor are shielded and
lubricated for the life of the bearing and require no
routine maintenance.
This motor is equipped with long life carbon
brushes. Brush life expectancy is affected by
motor loading. Heavy motor loading will result in
reduced brush life. If you notice a loss in power or
if the motor becomes excessively noisy, inspect
the brushes. If the brushes are worn down to 1⁄4''
(6mm) or less, it is time to replace them. When
checking brushes, be sure to return each brush to
the same hole in the same direction that it came
from. When replacing old brushes, replace both
brushes at the same time.

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 com-
ponents!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpre-
dictable results, including serious injury or fire.
This includes the installation of unapproved after-
market parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires dis-
connected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this man-
ual when connecting your machine to a power
source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious per-
sonal 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 expe-
riencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.
Wiring Safety Instructions

WARRANTY AND RETURNS
Grizzly Industrial, Inc. warrants every product it sells for a period of 1 year to the original purchaser from
the date of purchase. This warranty does not apply to defects due directly or indirectly to misuse, abuse,
negligence, accidents, repairs or alterations or lack of maintenance. This is Grizzly’s sole written warranty
and any and all warranties that may be implied by law, including any merchantability or fitness, for any par-
ticular purpose, are hereby limited to the duration of this written warranty. We do not warrant or represent
that the merchandise complies with the provisions of any law or acts unless the manufacturer so warrants.
In no event shall Grizzly’s liability under this warranty exceed the purchase price paid for the product and
any legal actions brought against Grizzly shall be tried in the State of Washington, County of Whatcom.
We shall in no event be liable for death, injuries to persons or property or for incidental, contingent, special,
or consequential damages arising from the use of our products.
To take advantage of this warranty, contact us by mail or phone and give us all the details. We will then
issue you a “Return Number,’’ which must be clearly posted on the outside as well as the inside of the
carton. We will not accept any item back without this number. Proof of purchase must accompany the
merchandise.
The manufacturers reserve the right to change specifications at any time because they constantly strive to
achieve better quality equipment. We make every effort to ensure that our products meet high quality and
durability standards and we hope you never need to use this warranty.
Please feel free to write or call us if you have any questions about the machine or the manual.
Thank you again for your business and continued support. We hope to serve you again soon.
