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 (34 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 1314" 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 512" x 191116" table features manual 13"  
(X-axis) and 512" (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  
understand the function and proper use of all con- workpiece to table or secure in a vise mounted to  
trols before starting. This will help you avoid mak- table, so workpiece cannot unexpectedly shift or

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.  
GROUNDED  
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).

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.

To lift machine and place it in position:  
Lifting & Placing  
1. Place shipping crate next to workbench (or  
stand) where machine will be placed.  
The Model G0758 mill/drill can be mounted to a  
workbench or the Model T26612 optional stand  
(see Figure 9). The optional stand is specifically  
designed for Model G0758 and comes with pre-  
drilled mounting holes.  
2. Use vertical handwheel to raise headstock as  
far as possible (see Figure 10). Lock head-  
stock in place to avoid sudden shifts during  
lifting.

3. Hang sling from forklift fork and place it under  
headstock, as shown in Figure 10. DO NOT  
place sling over any controls or against any  
components that may be damaged from the  
force required for lifting.  
HEAVY LIFT!  
Straining or crushing injury  
may occur from improperly  
lifting machine or some of  
its parts. To reduce this risk,  
get help from other people  
and use a forklift (or other  
lifting equipment) rated for  
weight of this machine.  
4. Unbolt machine from pallet. Have an assis-  
tant on the ground steady machine to prevent  
it from swinging and lift it slightly off the pallet  
with forklift.

The base of this machine has mounting holes  
that allow it to be fastened to a workbench or  
other mounting surface to prevent it from moving  
during operation and causing accidental injury or  
damage.  
Use a standard screwdriver to attach handwheel  
handles (see Figures 13–14).  
The strongest mounting option is a "Through  
Mount" (see example below) where holes are  
drilled all the way through the workbench—and  
hex bolts, washers, and hex nuts are used to  
secure the machine in place.

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.

3. Rotate variable-speed knob to lowest setting.  
Test Run  
4. Rotate high/low gearbox knob to low "L" gear  
setting (see Figure 17).  
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.  
High/Low

Serious injury or death can result from  
using this machine BEFORE understanding  
its controls and related safety information.  
DO NOT operate, or allow others to operate,  
machine until the information is understood.  
Figure 17. Gearbox knob rotated to low setting.  
5. Connect mill/drill to power supply.  
DO NOT start machine until all preceding  
setup instructions have been performed.  
Operating an improperly set up machine  
may result in malfunction or unexpect-  
ed results that can lead to serious injury,  
death, or machine/property damage.  
6. Press ON button. Spindle should begin to

6. Rotate variable-speed knob to 100 RPM and  
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.  
5. Press OFF button.

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

Figure 29. Formula for determining best spindle  
speed.  
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  
BEFORE PERFORMING LUBRICATION!  
Follow reasonable lubrication practices as  
outlined in this manual. Failure to do so  
could lead to premature failure of machine  
and will void warranty.

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

less than 4" long (new brushes are 8" long).
