SAFETY ACCESSORIES. To reduce the risk of
injury from flying chips, always use a face shield in
addition to safety glasses when using the mill/drill.
CL E AN - U P. Metal chips can cut your hands. DO
NOT clear chips by hand or compressed air that
can force the chips father into the machine. Use a
brush or vacuum, and never clear chips while the
spindle is turning.
SECURING TOOLING. Objects that are thrown
by the spinning action of the mill/drill can be
deadly missiles. Always firmly secure the cutting
tool before starting the machine. Always remove
the chuck key, drawbar wrench, and any tools
immediately after use.
CUTTING TOOL INSPECTION. Inspect cutting
tools for sharpness, chips, or cracks before each
use. Replace dull, chipped, or cracked cutting
tools immediately. Handle cutting tools with care.
Leading edges are very sharp and can cause
lacerations.
STOPPING SPINDLE. Serious injury may occur
if you try to stop the moving spindle by hand. DO
NOT stop the spindle using your hand or any other
object. Allow the spindle to stop on its own.
WORK HOLDING. A workpiece that moves unexpectedly during operation can result in personal
injury or damage to tooling and the machine. Before
starting the machine, be certain the workpiece is
properly clamped to the table. NEVER hold the
workpiece by hand during operation.
MACHINE CARE AND MAINTENANCE. Never
operate the mill/drill with damaged or worn parts
that can break apart and cause injury or property
damage. Maintain your mill/drill in proper working
condition. Perform routine inspections and maintenance promptly. Put tools away after use.
MAINTENANCE/ADJUSTMENTS. To avoid possible electrocution or physical injury, make sure
the mill is turned OFF, disconnected from power,
and all moving parts have come to a complete
stop before changing cutting tools or starting any
inspection, adjustment or maintenance procedure.
SPINDLE SPEEDS. For safe and good results,
select the spindle speed that is correct for the type
of work and material. Allow the spindle to reach
full speed before beginning a cut.
POWER DISRUPTION. In the event of a local
power outage during operation, turn spindle switch
OFF to avoid possible sudden start up once power
is restored.
Like all machinery there is potential danger
when operating this machine. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

SECTION 2: POWER SUPPLY
Before installing the machine, consider the availability 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
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.
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 overloading the machine during operation and make
sure it is connected to a power supply circuit that
meets the requirements in the following section.
This machine is prewired to operate on a 220V
power supply circuit that has a verified ground and
meets the following requirements:
For your own safety and protection of
Note: The circuit requirements listed in this manual 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 multiple 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 supply 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.)

We do not recommend using an extension cord
with this machine.
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 requirements:
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.
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 necessary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel 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, disconnect it from power, and immediately replace it with
a new one.
Serious injury could occur if you connect
The power cord and plug specified under “Circuit
Requirements for 220V”
has an equipment-grounding wire and a grounding 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).
No adapter should be used with the
required plug. If the plug does not fit the
available receptacle, or the machine must

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 workpiece 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 maintenance and service described in this manual.
See below for required space allocation.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
The physical environment where the machine is
operated is important for safe operation and longevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemicals, 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
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.

its parts. To reduce this risk,
Mounting
The machine base has holes to accommodate
mounting hardware. Additionally, you may consider providing a hole in your workbench or
stand for access to the underside of the machine
base. This will be necessary for adjusting the
Y-axis leadscrew backlash (refer to Adjusting
Leadscrew Backlash on Page 34 ).
and use a fork lift (or other
lifting equipment) rated for
weight of this machine.
To move your machine into position:
1. Move the shipping crate next to the work-
bench or stand you have for the mill/drill, then
unbolt the machine from the pallet.
2. To help balance the machine during moving,
move the table as close to the column as
possible, and raise the headstock to its highest position.
3. Place a lifting strap under the headstock of
the machine, as shown in Figure 5, connect
it to a forklift, then lift and place the machine.
Note: Make sure you tighten all the locks that
restrict moving parts to avoid sudden shifts
which could unbalance the machine.
The strongest mounting option is a "Through
Mount" where holes are drilled all the way through
the workbench, and hex bolts, washers, and hex
nuts are used to secure the mill/drill to the workbench (Figure 6).

Spindle Bearing
Inspections &
Break-In
Complete the spindle bearing break-in procedure to prevent rapid wear and tear of
spindle components once the mill is placed
into operation.
Before operation loads are placed on the spindle
bearings, complete this break-in procedure to fully
distribute internal lubrication and reduce the risk
of early failure.
To perform the spindle break-in procedure:
1. Make sure the spindle is completely stopped
and set the spindle speed to 90 RPM (refer to
Page 25 for detailed instructions).
Adjustments
The following list of adjustments were performed
at the factory before the machine was shipped:
Be aware that machine components can shift
during the shipping process. Pay careful attention to these adjustments during operation of the
machine. If you find that the adjustments are not
set according to the procedures in this manual or
your personal preferences, re-adjust them.
Do not leave the lathe unattended during
the Spindle Break-In procedure. If your
attention is needed elsewhere during this
procedure, stop the lathe and restart the
procedure later from the beginning.
2. Run the machine for a minimum of 10 min-
utes.
3. Repeat Step 2 for each of the spindle speeds.
4. Change the headstock oil (refer to Page 28
for detailed instructions).
The spindle break-in of the mill is now complete!

To remove tooling:
Spindle Speed
Using the correct spindle speed is important for
safe and satisfactory results, as well as maximizing tool life.
1. DISCONNECT MACHINE FROM POWER!
2. Remove the drawbar cap, and unthread the
drawbar from the tool one full rotation.
Note: Do not fully unthread the tool from the
drawbar, or the drawbar and tool threads
could be damaged in the next step.
3. Tap the top of the drawbar with the hammer
to unseat the taper.
4. Hold on to the tool with one hand and fully
unthread the drawbar.
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 spindle
speed.
Determining Spindle Speed
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 22.
*Recommended
Cutting Speed (FPM) x 12
Tool Dia. (in inches) x 3.14
Spindle
=
Speed
(RPM)
*Double if using carbide cutting tool
Figure 22. Spindle speed formula for mill/drills.
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, provide 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 determine the best spindle speed for the operation.

maintenance, or service.
Schedule
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Check:
• Loose mounting bolts.
• Damaged tooling.
• Worn or damaged wires.
• Clean debris and built up grime off of machine.
• Any other unsafe condition.
Every 8 Hours of Operation:
• Check/add headstock oil (Page 29).
• Lubricate ball oilers (Page 30).
• Lubricate table ways, column and rack, and
quill (Page 30).
Every 40 Hours of Operation:
•Lubricate table leadscrews (Page 31).
Every 90 Hours of Operation:
•Lubricate quill rack and pinion (Page 31).
Protecting
Metal chips left on the machine that have been
soaked with water-based coolant will invite oxidation and a gummy residue build-up around the
moving parts. Use a brush and shop vacuum to
remove chips and debris from the working surfaces 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.
Remove any rust build-up from unpainted cast
iron surfaces of your mill/drill and treat with a nonstaining lubricant after cleaning.
Keep unpainted cast iron surfaces rust-free with
regular applications ISO 68 way oil (see Page 26
for offerings from Grizzly).
Lubrication
An essential part of lubrication is cleaning the
components before lubricating them.
This step is critical because grime and chips build
up on lubricated components, which makes them
hard to move. Simply adding more lubricant will
not result in smooth moving parts.
Every 180 Days of Operation:
• Change headstock oil (Page 29).

Clean all exterior components in this section with
mineral spirits, shop rags, and brushes before
lubricating.
DISCONNECT MACHINE FROM POWER
BEFORE PERFORMING LUBRICATION!
NOTICE
Follow reasonable lubrication practices as
outlined in this manual. Failure to do so
could lead to premature failure of your
machine and will void the warranty.

Proper lubrication of ball oilers shown in
Figures 35–36 is done with a pump-type oil can
that has a plastic or rubberized cone tip (see
Page 26 for offerings from Grizzly). We do not
recommend using metal needle or lance tips, as
they can push the ball too far into the oiler, break
the spring seat, and lodge the ball in the oil galley.

Adjusting Gibs
Gibs are tapered lengths of metal that are sandwiched between two moving surfaces. Gibs control the gap between these surfaces and how they
slide past one another. Correctly adjusting the
gibs is critical to producing good milling results.
Tight gibs make table movement more accurate
but stiff. Loose gibs make moving the table sloppy
but easier to do. The goal of gib adjustment is to
remove unnecessary sloppiness without causing
the ways to bind.
Tip: Some experienced machinists recommend
adjusting the gibs until there is a slight drag in
table movement.
Screws on each end of the gib allow gib adjustment to increase or decrease the friction pressure
between the sliding surfaces. Correctly positioning the gib is a matter of trial and error and
patience.
DISCONNECT MACHINE FROM POWER
BEFORE ADJUSTING THE GIBS!
Make sure all table locks are loose. Then, loosen
one gib adjustment screw (see Figure 42) 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.
Adjusting Leadscrew
Backlash
Leadscrew backlash is the amount of freeplay
movement in the leadscrew (when changing the
direction of rotation) before the attached device
begins to move.
Leadscrews must have a certain amount of backlash, but over time, this will increase with normal
wear. Generally, 0.003"–0.006" leadscrew backlash 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 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.
The X-axis leadscrew nut shown in Figure 43
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.
