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.

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 making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.
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 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.

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 A N - UP. 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-

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.

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.

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.

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.
