INTRODUCTION
Machine Description
Manual Accuracy
We are proud to provide a high-quality owner’s
manual with your new machine!
The Model G0758 is a high-precision mill/drill with
a 600 Watt (3⁄4 HP) high-torque, low noise motor,
with low speed gearing for maximum torque in the
lowest RPM range.
We made every effort to be exact with the instruc-
tions, specifications, drawings, and photographs
contained inside. Sometimes we make mistakes,
but our policy of continuous improvement also
means that sometimes the machine you receive
will be slightly different than what is shown in
the manual.
This mill/drill has a spindle-to-table distance of 9"
with a 131⁄4" swing. It has an R-8 spindle size and
features manual downfeed controls with a variable
spindle speed range from 50–2000 RPM. DRO's
for both the spindle speed and spindle downfeed
stroke allow precise operation. The headstock tilts
45° left/right and moves in the Z-axis along dove-
tailed ways for maximum precision.
If you find this to be the case, and the difference
between the manual and machine leaves you
confused about a procedure, check our website
for an updated version. We post current manuals
and manual updates for free on our website at
The large 51⁄2" x 1911⁄16" table features manual 13"
(X-axis) and 51⁄2" (Y-axis) travel. All table move-
ment is along precision-ground dovetailed ways.

Additional Safety for Mills/Drills
The primary risks of operating a Mill/Drill are as follows: You can be seriously injured or killed
by getting clothing, jewelry, or long hair entangled with rotating cutter. You can be severely cut
or your fingers can be amputated by contacting the rotating cutter. You can be blinded or struck
with great force by broken cutting tools, metal chips, workpieces, or adjustment tools thrown
from the rotating spindle. To reduce your risk of serious injury when operating this machine,
completely heed and understand the following:
UNDERSTAND ALL CONTROLS. Make sure you SECURE WORKPIECE TO TABLE. Clamp

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 electrician or
qualified service personnel in accordance with all
applicable codes and standards.
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.
110V Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage .................... 110V, 115V, 120V
Cycle..........................................................60 Hz
Phase........................................... Single-Phase
Power Supply Circuit ......................... 15 Amps
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
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.)
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.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Full-Load Current Rating at 110V........ 8 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.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
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 specified circuit requirements.

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.
Grounding & Plug Requirements
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
This machine is equipped with a power cord that
has an equipment-grounding wire and a 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.
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.

5-15 RECEPTACLE
Extension Cords
Grounding Prong
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.
5-15 PLUG
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).

and receptacle, and meet the following require-
Minimum Gauge Size...........................16 AWG
Maximum Length (Shorter is Better).......50 ft.
SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug provided—if
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.

Cleanup
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. Avoid
using these products
to clean machinery.
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.
Many cleaning solvents
are toxic if inhaled. Only
work in a well-ventilated
area.
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.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.
Before cleaning, gather the following:
•
•
•
•
Disposable rags
Cleaner/degreaser (WD•40 works well)
Safety glasses & disposable gloves
Plastic paint scraper (optional)
T23692—Orange Power Degreaser
A great product for removing the waxy shipping
grease from machine during clean up.
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.
Figure 7. T23692 Orange Power Degreaser.
4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.

Site Considerations
Weight Load
Physical Environment
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.
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.
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.
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 enough space
around machine to disconnect power supply or
apply a lockout/tagout device, if required.
Lighting
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
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.

Joining Drill Chuck Lubricating Mill/Drill
& Arbor
The lubrication procedures highlighted in the
Lubrication subsection of SECTION 6:
A B-16 x R8 arbor is included for the drill chuck
that comes with this machine. The following pro-
cedure describes how to install the arbor in the
chuck.
MAINTENANCE must be completed before per-
forming the test run or spindle break-in.
After the arbor is installed in the drill chuck, it
is very difficult to separate the assembly. If you
would like to use a different chuck in the future,
we recommend getting a new arbor for that chuck.
Damage caused by running the mill/drill
without first properly lubricating headstock
gears will not be covered under warranty.
Important: DO NOT install the drill chuck and
arbor into the spindle until AFTER the test run.
To join drill chuck and arbor:
1. Use mineral spirits to clean drill chuck and
arbor mating surfaces, especially the bore.
2. Retract chuck jaws completely into chuck.
3. Insert small end of arbor into chuck.
4. Hold assembly by arbor and tap chuck onto
a block of wood with medium force, as illus-
trated in Figure 15.
Figure 15. Tapping drill chuck/arbor on block of
wood.
5. Attempt to separate drill chuck and arbor by
hand. If you can pull them apart, repeat this
procedure.
Note: Refer to Installing/Removing Tooling sec-
tion on Page 25 for installing arbor into spindle
instructions.

Once assembly is complete, test run the machine
to ensure it is properly connected to power and
safety components are functioning properly.
Note: When switching between gears, it may
be necessary to rotate spindle by hand so
gears will align and engage.
If you find an unusual problem during the test run,
immediately stop the machine, disconnect it from
power, and fix the problem BEFORE operating the
machine again. The Troubleshooting table in the
SERVICE section of this manual can help.

Spindle Break-In
high/low gearbox knob to high "H".
7. Press ON button.
The spindle break-in procedure distributes lubri-
cation throughout the bearings to reduce the risk
of early bearing failure if there are any "dry" spots
or areas where lubrication has settled in the bear-
ings. You must complete this procedure before
placing operational loads on the spindle for the
first time when the machine is new or if it has
been sitting idle for longer than 6 months.
8. Run machine for a minimum of 10 minutes.
9. Without stopping spindle, use variable-speed
knob to run machine at 1000 and 2000 RPM
for 10 minutes each.
10. Press OFF button.
Always start the spindle break-in at the lowest
speed to minimize wear if there are dry spots.
Allow the spindle to run long enough to warm up
and distribute the bearing grease, then incremen-
tally increase spindle speeds, allowing the spindle
to run the same amount of time at each speed, until
reaching the maximum spindle speed. Following
the break-in procedure in this progressive man-
ner helps minimize any potential wear that could
occur until lubrication is fully distributed.
The spindle break-in of the machine is now
complete!
Inspections &
Adjustments
The following adjustments were performed at the
factory before the machine was shipped:
•
•
Gib Adjustments............................. Page 34
Leadscrew Backlash
Adjustments.................................... Page 34
You must complete this procedure to main-
tain the warranty. Failure to do this could
cause rapid wear-and-tear of spindle bear-
ings once they are placed under load.
Be aware that these can change during the
shipping process. Pay careful attention to these
adjustments when first operating the machine. If
you find that the adjustments are not set to your
personal preferences, re-adjust them.
To perform spindle break-in procedure:
1. Rotate variable-speed knob to 50 RPM and
high/low gearbox knob to low "L".
2. Press ON button.
3. Run spindle for minimum of 10 minutes.
4. Without stopping spindle, use variable-speed
knob to run machine at 500 and 1000 RPM
for 10 minutes each.

Spindle Speed
Qty
Using the correct spindle speed is important for
safe and satisfactory results, as well as maximiz-
ing tool life.
To remove tooling:
To set the spindle speed for operation, you will
need to: 1) Determine the best spindle speed for
the cutting/drilling task, and 2) adjust the gear box
knob and variable-speed knob to produce deter-
mined speed.
1. DISCONNECT MACHINE FROM POWER!
2. Remove drawbar cap and secure spindle
with spindle pin. Unthread drawbar from tool-
ing one full rotation.
Determining Spindle Speed
Note: Do not fully unthread tooling from
drawbar or the drawbar and tool threads
could be damaged in the next step.
Many variables affect the optimum spindle speed
to use for any given operation, but the two most
important are the recommended cutting speed
for the workpiece material and the diameter of
the cutting tool, as noted in the formula shown in
Figure 29.
3. Tap top of drawbar with brass hammer to
unseat taper.
4. Hold onto tooling with one hand and fully
unthread drawbar.

Cutting speed, typically defined in feet per minute
(FPM), is the speed at which the edge of a tool
moves across the material surface.
A recommended cutting speed is an ideal speed
for cutting a type of material in order to produce
the desired finish and optimize tool life.
The books Machinery’s Handbook or Machine
Shop Practice, and some internet sites, pro-
vide excellent recommendations for which cutting
speeds to use when calculating the spindle speed.
These sources also provide a wealth of additional
information about the variables that affect cutting
speed and they are a good educational resource.
Also, there are a large number of easy-to-use
spindle speed calculators that can be found on
the internet. These sources will help you take into
account the applicable variables in order to deter-
mine the best spindle speed for the operation.

SECTION 6: MAINTENANCE
Cleaning and
To reduce risk of shock or
accidental startup, always
disconnect machine from
Protecting
power before adjustments,
maintenance, or service.
Metal chips left on the machine that have been
soaked with water-based coolant will invite oxida-
tion and a gummy residue build-up around the
moving parts. Use a brush and shop vacuum to
remove chips and debris from the working sur-
faces of the mill/drill. Never blow off the mill/drill
with compressed air, as this will force metal chips
deep into the mechanisms and may cause injury
to yourself or bystanders.
Schedule
For optimum performance from the machine, fol-
low this maintenance schedule and refer to any
specific instructions given in this section.
Remove any rust build-up from unpainted cast
iron surfaces of mill/drill and treat with a non-
staining lubricant after cleaning.
Daily Check:
•
•
•
•
•
Loose mounting bolts.
Damaged tooling.
Clean debris and built up grime off of machine.
Worn or damaged wires.
Any other unsafe condition.
Protect other unpainted cast iron surfaces with
regular applications of products like G96® Gun
Treatment, SLIPIT®, or Boeshield® T-9. (See
Accessories on Page 27 for more details.)
Every 8 Hours of Operation:
•
•
Lubricate table and column ways (Page 29).
Lubricate quill outside surface (Page 31).
Lubrication
Every 40 Hours of Operation:
Lubricate table leadscrews (Page 30).
•
An essential part of lubrication is cleaning the
components before lubricating them.
Every 90 Hours of Operation:
•
•
Headstock gears (Page 30).
Lubricate quill rack (Page 31).
This step is critical because grime and chips build
up on lubricated components over time, which
makes them hard to move.
Every 120 Hours of Operation:
Clean all exterior components in this section with
mineral spirits, shop rags, and brushes before
lubricating.
•
Lubricate column leadscrew (Page 29).
DISCONNECT MACHINE FROM POWER

Adjusting Gibs
Adjusting Leadscrew
Backlash
Gibs are tapered lengths of metal sandwiched
between two moving surfaces to control how
much friction they have when they slide past one
another. Correctly adjusting the gibs is critical to
producing accurate milling results.
Leadscrew backlash is the amount of free-play
movement in the leadscrew (when changing the
direction of rotation) before the attached device
begins to move.
Tight gibs make table movement more accurate
but stiff. Loose gibs make table movement sloppy
but easy. The goal of gib adjustment is to remove
unnecessary sloppiness without causing the ways
to bind.
Leadscrews must have a certain amount of back-
lash, but over time, this will increase with normal
wear. Generally, 0.003"–0.006" leadscrew back-
lash is acceptable to ensure smooth movement
and reduce the risk of premature thread wear.
Tip: Many experienced machinists adjust the gibs
until there is just a slight drag in table movement.
The X- and Y-axis leadscrew backlash is adjusted
by using a long 5mm hex wrench to tighten/loosen
the cap screw on the leadscrew nut. This adjusts
the force the split leadscrew nut exerts on the
leadscrew threads.
Screws on each end allow gib adjustment to
increase or decrease the friction between the slid-
ing surfaces of the ways.
The X-axis leadscrew nut shown in Figure 45
is accessed from underneath the left side of the
table.
DISCONNECT MACHINE FROM POWER
BEFORE ADJUSTING THE GIBS!
Make sure all table locks are loose. Then, loosen
one gib adjustment screw (see Figure 44) and
tighten the opposing screw the same amount to
move the gib, while at the same time using the
handwheels to move the table until you feel a
slight drag in that path of movement.

3. Unscrew one of the brush caps (see
Figure 47).
Brush Replacement
This mill/drill is equipped with a universal motor
that uses two carbon brushes to transmit elec-
trical current inside the motor. These brushes
are considered to be regular "wear items" or
"consumables" that will need to be replaced dur-
ing the life of the motor. The frequency of required
replacement is often related to how much the
motor is used and how hard it is pushed.
Brush Cap
Replace the carbon brushes (part number:
P0758202) when the motor no longer reach-
es full power, or when the brushes measure
