Additional Safety for Mill/Drills
The primary risks of operating a mill 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 have fingers amputated from contact with the rotating cutter. You can be blinded or struck
by broken cutting tools, metal chips, workpieces, or adjustment tools thrown from the rotating
spindle with great force. To reduce your risk of serious injury when operating this machine,
completely heed and understand the following:
UNDERSTAND ALL CONTROLS. Make sure you PROPERLY SECURE WORKPIECE. Clamp

SECTION 2: POWER SUPPLY
Availability
Circuit Requirements for 220V
This machine is prewired to operate on a 220V
power supply circuit that has a verified ground and
meets the following requirements:
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.
Nominal Voltage ........................................220V
Cycle..........................................................60 Hz
Phase........................................... Single-Phase
Power Supply Circuit ......................... 15 Amps
Plug/Receptacle ......................................... 6-15
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.)
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
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
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.
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.
Full-Load Current Rating at 220V....6.8 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.
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.

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 Instructions
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.
The power cord and plug specified under “Circuit
Requirements for 220V” on the previous page
has an equipment-grounding wire and a ground-
ing prong. 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 (see figure below).
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
6-15 RECEPTACLE
Extension Cords
Current Carrying Prongs
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.
6-15 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).
Grounding Prong

Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
Minimum Gauge Size...........................14 AWG
Maximum Length (Shorter is Better).......50 ft.
No adapter should be used with the
required plug. If the plug does not fit the
available receptacle, or the machine must
be reconnected for use on a different type
of circuit, the reconnection must be made
by a qualified electrician and comply with all
local codes and ordinances.

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 your 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 5. 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 access to
a means of disconnecting the power source or
engaging 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.

"
HEAVY LIFT!
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.
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.
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.
To lift and place machine into position:
1. Move shipping crate next to workbench or
Hex
Bolt
stand, then unbolt machine from pallet.
2. Move machine work table as close to column
as possible, and raise headstock to its high-
est position. This will help balance machine
when moving.

Assembly
Joining Drill Chuck
& Arbor
The mill/drill was fully assembled at the factory
except for the handwheel handles.
An arbor is included for the drill chuck that
comes with this machine. The following procedure
describes how to install the arbor in the chuck.
Use a flathead screwdriver to attach the
handwheels handles, as shown in Figure 10.
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 obtaining a new arbor.
Important: DO NOT install the drill chuck and
arbor assembly into the spindle until AFTER the
test run.
To join drill chuck and arbor:
Handwheel Handles
1. Use acetone or lacquer thinner to clean drill
chuck and arbor mating surfaces, especially
the bore.
Figure 10. Handwheel handles attached.
2. Retract chuck jaws completely into chuck.
3. Insert small end of arbor into chuck.
4. Hold assembly by the arbor and tap chuck
onto a block of wood with medium force, as
illustrated below.

4. Repeat Step 3 for each remaining speed,
working from lowest to highest. The Spindle
Bearing Break-In is now complete!
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.
Inspections &
Adjustments
The following adjustments were performed at the
factory before the machine was shipped:
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 and repeat this pro-
cess at each speed until reaching the maximum
spindle speed. Following the break-in procedure
in this progressive manner helps minimize any
potential wear that could occur before lubrication
is fully distributed.

Please be aware that these adjustments can
change during the shipping process. Pay careful
attention to these adjustments when first operat-
ing the machine. If you find that adjustments are
not set to your personal preference, re-adjust
them.
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.
After completing the spindle break-in procedure,
we recommend changing the headstock oil to
flush any small particles that may be present in
the headstock from the manufacturing process.
Refer to the Lubrication section on Page 34 for
detailed instructions.
To perform spindle break-in procedure:
1. Set mode switch to Drill.
2. Set spindle speed to 115 RPM (see Spindle
Speed on Page 26 for details). Run for 10
minutes in each direction of rotation (FWD
and REV).

Fine Downfeed
Using Spindle
To engage the fine downfeed, turn the downfeed
selector knob clockwise until tightened. When fine
downfeed is engaged, the spindle only moves up
or down when the handwheel is rotated (there is
no automatic spindle return to the top position, as
with the coarse downfeed controls). This manual
level of control makes it easy to precisely lock the
spindle height in place with the quill lock lever
when milling a flat surface across the face of a
workpiece, to ensure the spindle height does not
move until the entire milling operation is complete.
Downfeed Controls
The Model G0795 is equipped with coarse and
fine spindle downfeed controls as shown in
Figure 14. Coarse downfeed is typically used with
drilling operations, and fine downfeed is typically
used with milling operations.
Coarse
Downfeed
Handle
Fine
Downfeed

The graduated dial measures spindle movement
in 0.001" increments, with one full revolution
equaling 0.10" of spindle travel.
Using Fine Downfeed Controls
The fine downfeed handwheel allows for a pre-
cise amount of material to be removed from the
workpiece.
In the following example, the fine downfeed
controls are used to mill 0.010" off a workpiece:
Downfeed
Selector
Knob
Quill Lock
Lever
1. Use headstock elevation crank (see Figure
16 on next page) to adjust cutting tool just
above workpiece surface, then secure the
headstock with Z-axis lock levers.
Figure 14. Spindle controls.
Coarse Downfeed
When coarse downfeed is engaged, pull handles
downward to lower the spindle. An internal coil
spring will raise the spindle back up when you
stop applying downward pressure on the handle.
2. Tighten downfeed selector knob (see Figure
14) to engage fine downfeed handwheel.
3. Loosen quill lock lever.
Note: To maintain control of the upward spindle
travel and the rotating bit in your workpiece,
always continue holding the handle until the
spindle returns to the top position. Letting go of
the coarse downfeed handles when the spindle
is in the lowered position will cause the spindle to
retract too quickly and slam up into the headstock
or lift the workpiece and cause it to spin out of
control.
4. Rotate fine downfeed handwheel clockwise
and lower cutting tool so it just touches
workpiece.
5. Move workpiece out of the way.
6. Using graduated dial to gauge spindle move-
ment, rotate fine downfeed handwheel clock-
wise 0.010".
The coarse downfeed hub features a graduated
dial that measures spindle movement in 0.001"
increments, with one full revolution equaling 0.10"
of spindle travel.
7. Tighten quill lock lever.
8. Turn mill/drill ON and perform cutting pass.

5. Adjust the depth stop pointer to the "0" mark
on the scale to calibrate it to the workpiece,
then remove the sheet stock and tighten the
headstock elevation lock levers.
Setting Depth Stop
The depth stop limits the downward movement of
the cutting tool when drilling or tapping the same
size hole in multiple workpieces. The depth stop
adjustment knob is used to position the depth stop

depth stop is provided in front of the depth scale
to help you set the approximate hole depth, but
the scale depth can only be relied on if the spindle
height is first positioned so the bottom of the drill
of tap is just above the top of the workpiece.
Note: The depth scale functions as a general
guide only.

Setting Spindle Speed
Setting Spindle
Speed
Use the chart below or the one on the headstock
when setting the spindle speed. With the spindle
completely stopped, position the high/low range
and spindle speed knobs as indicated by the
spindle speed chart (see Figure 25) to set the
desired spindle RPM.
Using the correct spindle speed is important for
safe and satisfactory results, as well as maximiz-
ing tool life.
Note: If necessary, rotate the spindle a little by
hand to mesh the gears when changing speeds.
To set the spindle speed for your operation, you
will need to (1) determine the best spindle speed
for the cutting task, and (2) configure the spindle
speed levers to produce the required speed.

moves across the material surface.
Spindle Speed
Knob
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.
Figure 25. Spindle speed controls.
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.
Change spindle speed ONLY when the
spindle is completely stopped. Otherwise,
machine damage could occur.
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 &
Protecting
To reduce risk of shock or
accidental startup, always
disconnect machine from
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
Schedule
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
deep into the mechanisms and may cause injury
to yourself or bystanders.
Remove any rust build-up from unpainted cast
iron surfaces of your mill/drill and treat with a non-
staining lubricant after cleaning.
Daily Check:
•
•
•
•
•
Loose mounting bolts.
Damaged saw blade.
Worn or damaged wires.
Clean debris and built up grime off of machine.
Any other unsafe condition.
Keep unpainted cast iron surfaces rust-free with
regular applications of ISO 68 way oil (see Page
28 for offerings from Grizzly).
Every 8 Hours of Operation:
•
•
•
•
Check/add headstock oil (Page 34).
Lubricate ball oilers (Page 35).
Lubricate table and column ways (Page 35).
Lubricate quill outside surface (Page 36).
NOTICE
The recommended lubrication is based on
light-to-medium usage. Since lubrication
helps to protect value and operation of
machine, these lubrication tasks may need
to be performed more frequently than rec-
ommended, depending on usage.
Every 40 Hours of Operation:
Lubricate table leadscrews (Page 36).
•
Every 90 Hours of Operation:
Failure to follow reasonable lubrication
practices as instructed in this manual could
lead to premature failure of machine com-
ponents and will void the warranty.

Adjusting Gibs
Adjusting Leadscrew
Backlash
The gibs affect the accuracy of the work table by
restricting slide movements along their ways.
Tool Needed
Qty
Hex Wrench 4mm (long).................................... 1
Screws on each end allow gib adjustments to
increase or decrease the friction between the slid-
ing surfaces of the ways.
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.
The goal of gib adjustment is to remove unneces-
sary sloppiness without causing binding in the
dovetail ways. Tight gibs make the movements
more accurate, but harder to perform. Loose
gibs make the movements sloppy, but easier to
perform. Many experienced machinists adjust the
gibs until there is just a slight drag in table move-
ment.
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.
The X- and Y-axis leadscrew backlash is adjusted
by using a long hex wrench to tighten/loosen the
cap screw on the leadscrew nut. This adjusts the
force that the split leadscrew nut exerts on the
leadscrew threads.
DISCONNECT MACHINE FROM POWER
BEFORE ADJUSTING THE GIBS!
Make sure all table locks are loose. Then, loosen
one gib adjustment screw (see Figure 57) 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.
The X-axis leadscrew nut shown in Figure 58
is accessed from underneath the left side of the
table.
The Y-axis leadscrew nut is similar and is accessed
from underneath the machine base.

ing next step.
Important: Do not perform this procedure unless
it is absolutely necessary. The high amount of
spring tension involved can make this a difficult
procedure. Return spring tension is adjusted at
the factory and should be suitable for most appli-
cations.
Note: Keep a good grip on spring cover dur-
ing next step. Letting go of cover when roll
pin is not engaged will cause spring to rapidly
uncoil.
5. While holding spring cover against side of
headstock so spring will not unwind, loosen
thumb screw approximately 1⁄4".
If the return spring should
come loose from the spring
cap and rapidly unwind,
laceration or impact inju-
ries could occur. Always
6. Pull cover out just enough to disengage it with
roll pin, then rotate it clockwise to engage roll
pin in next slot in cover.
Eye injury hazard! Always
wear safety glasses when

and safety glasses when
adjusting the return spring
tension.
During this procedure, you will loosen the spring
cover thumb screw (see Figure 59) just enough
to pull the cover back to clear the roll pin, then
rotate the cover clockwise to fit the roll pin in the
next slot.

Note: A precision-ground plate can be substi-
tuted for the parallel blocks. Keep in mind that
the farther the indicator point can be placed from
the spindle axis, the more accurate the alignment
measurements will be.
Tramming Spindle
After positioning the head at an angle and when
your operation requires that the spindle axis be
precisely perpendicular to the table, you must
tram or align the spindle with the table to ensure
the spindle is exactly 90° to the table.
To tram spindle to table:
1. DISCONNECT MACHINE FROM POWER!
This procedure involves mounting a dial test
indicator to the quill or spindle, rotating it around
the table, and adjusting the spindle axis (Z-axis)
90° to the table X- and Y-axis, as illustrated in
Figure 60.
2. Prepare mill for tramming by performing fol-
lowing tasks:
• Verify the table is clean by running your
hand over the top of it. If necessary, stone
the table to remove all nicks and burrs,
then clean off all debris.

• Position the table for the milling operation
you intend to perform after tramming—
preferably centered with the saddle.

• Tighten the quill lock lever used during
intended milling operations.

3. Place parallel block underneath spindle.

4. Install indicator holder in spindle or on quill,
then mount indicator so that point is as paral-
lel to block as possible (see Figure 61).
Figure 60. Spindle Z-axis perpendicular to the
table X- and Y-axis.
We encourage you to research the many varia-
tions of spindle tramming to find the one that
works best for you. If you do not already have a
preference for performing this operation, use the
following widely-used procedure for accurately
tramming the spindle to the table.

Keep in mind that all workpiece top surfaces are
not exactly parallel with the table top. You may
choose to tram the spindle to the top surface of
the workpiece after it is mounted rather than tram-
ming the spindle to the table.

5. To measure spindle alignment along X-axis,
place parallel block directly under spindle and
indicator across length of table, as illustrated
in Figure 62.
Note: Keep one of the rotation lock bolts
just snug so the head does not move loosely
while you adjust it. Remember to tighten
all the rotation lock bolts after adjusting the
head.
Note: If you must re-position the quill or the
knee to accommodate the above step, then
review the tasks in Step 2 to make sure the
mill is properly prepared for tramming.
8. Place parallel block directly under spindle
and across width of table, as illustrated in
Figure 63.

Figure 63. Parallel block and indicator positioned
for the Y-axis measurement
(top view).
Note: Your general goal in the next steps
should be to get the difference of the indicator
readings between the ends of the parallel bar
down to 0.0005". However, the acceptable
variance will depend on the requirements for
your operation.
9. Rotate spindle so indicator point rests on par-
allel bar, as illustrated in Figure 63, then zero
the dial.
10. Rotate spindle so that indicator point rests on
other end of bar in same manner, then read
dial.
6. Rotate spindle by hand so that indicator point
rests on one end of parallel block, as illus-
trated in Figures 61–62, then zero the dial.
—If the indicator dial still reads zero or is
within the acceptable variance, the spindle
is precisely perpendicular to the table in
both the X- and Y-axis, and the tramming
procedure is complete.
7. Rotate spindle so that indicator point rests
in same manner on other end of block, then
read dial.
—If the indicator dial has moved from zero
beyond the acceptable variance, you will
need to compensate for that amount by tilt-
ing the head forward or backward. Repeat
Steps 9–10 until you are satisfied with
the spindle axis alignment along the table
Y-axis.
—If the indicator dial still reads zero or is
within the acceptable variance, continue on
with Step 8.
—If the indicator dial has moved from zero
beyond the acceptable variance, you will
need to compensate for that amount by
rotating the head left or right. Repeat Steps
6–7 until you are satisfied with the spindle
axis alignment along the table X-axis.
Note: Keep one of the tilt lock bolts just snug
so the head does not move loosely while you
adjust it. Remember to tighten all the tilt lock
bolts after adjusting the head.
