Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip­ment, such as those dust masks that are specially designed to filter
out microscopic particles.

SECTION 1: SAFETY

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 impor­tance 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.

Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.

This symbol is used to alert the user to useful information about

proper operation of the machine.

Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your 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 machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

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.
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.

Always discon-

WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate­rial. Always wear a NIOSH-approved respirator to
reduce your risk.

HEARING PROTECTION. Always wear hear­ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica­tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.

FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.

NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement dur­ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec­ommended accessories. Using improper acces­sories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.

MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!

MAINTAIN POWER CORDS. When disconnect­ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend­ed operation, stop using the machine! Contact our
Technical Support at [phone].

Additional Safety for Milling Machines

You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with
rotating cutter/spindle. You can be severely cut or have fingers amputated from contact with
rotating cutters. 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 understand the function and proper use of all
controls before starting. This will help you avoid
making mistakes that result in serious injury.

AVOIDING ENTANGLEMENT. DO NOT wear
loose clothing, gloves, or jewelry, and tie back
long hair. Keep all guards in place and secure.
Always allow spindle to stop on its own. DO NOT
stop spindle using your hand or any other object.

WEAR FACE SHIELD. Always wear a face shield
in addition to safety glasses. This provides more
complete protection for your face than safety
glasses alone.

USE CORRECT SPINDLE SPEED. Follow rec­ommended speeds and feeds for each size and
type of cutting tool. This helps avoid tool breakage
during operation and ensures best cutting results.

INSPECT CUTTING TOOL. Inspect cutting tools
for sharpness, chips, or cracks before each use.
Replace dull, chipped, or cracked cutting tools
immediately.

PROPERLY SECURE CUTTER. Firmly secure
cutting tool or drill bit so it does not fly out of spin­dle during operation.

POWER DISRUPTION. In the event of a local
power outage during operation, turn spindle
switch OFF to avoid a possible sudden startup
once power is restored.

CLEAN MACHINE SAFELY. Metal chips or shav­ings can be razor sharp. DO NOT clear chips
by hand or compressed air that can force chips
farther into machine—use a brush or vacuum
instead. Never clear chips while spindle is turning.

SECURE WORKPIECE TO TABLE. Clamp work­piece to table or secure in a vise mounted to table,
so workpiece cannot unexpectedly shift or spin
during operation. NEVER hold workpiece by hand
during operation.

PROPERLY MAINTAIN MACHINE. Keep
machine in proper working condition to help
ensure that it functions safely and all guards and
other components work as intended. Perform rou­tine inspections and all necessary maintenance.
Never operate machine with damaged or worn
parts that can break or result in unexpected move­ment during operation.

DISCONNECT POWER FIRST. To reduce risk of
electrocution or injury from unexpected startup,
make sure mill/drill 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.

REMOVE CHUCK KEY & SPINDLE TOOLS.
Always remove chuck key, drawbar wrench, and
other tools used on the spindle immediately after
use. This will prevent them from being thrown by
the spindle upon startup.

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 electrician or
qualified service personnel in accordance with all
applicable codes and standards.

or equipment damage
may occur if machine is
not properly grounded
and connected to 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 specified circuit requirements.

For your own safety and protection of

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, con­sult an electrician or qualified service personnel to
ensure 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.)

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.

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 preven­tative, but the following steps work well in a wide
variety of situations. Always follow the manufac­turer’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)

Site Considerations

Weight Load

Refer to the
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.

Lifting & Placing

get help from other people

HEAVY LIF T!
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,

and use a forklift (or other
lifting equipment) rated for
weight of this machine.

Use a forklift and at least two other people (see
Page 18) to lift the machine off the pallet and onto
a suitable location.

To lift and move mill:

Note: After re-positioning ram and head-

stock, make sure they are locked in place to
prevent unexpected movement during lifting.

Make sure the four turret lock bolts (two on

each side of the ram, see Figure 12) are
torqued to 47 ft./lbs. to keep the ram from
unexpectedly moving from the force of the
lifting straps.

Turret Locking Bolts

(2 of 4)

1. Remove crate from shipping pallet, then
with mill still on pallet, move to installation
location.

2. Rotate ram 180° so headstock is facing
backwards (see Figure 11), then rotate head
upright.

Refer to Positioning Head on Page 32 and

Positioning Ram on Page 33 for detailed
instructions to help with this step.

Safety Hook

Lifting Straps

Facing Backward

Figure 12. Locations of turret locking bolts.

3. Place lifting straps under ram and con-

nect them to safety hook, as illustrated in
Figure 11.

Note: Place protective material between

straps and mill to protect ram and ways, and
to keep from cutting lifting straps.

4. Unbolt mill from shipping pallet.

5. With other people steadying load to keep it

from swaying, lift mill a couple of inches.

— If mill tips to one side, lower it to the

ground and adjust ram or table to balance
the load. Make sure to re-tighten lock
levers and bolts before lifting mill again.

— If mill lifts evenly, remove shipping pallet

and lower mill onto its prepared location.

Model G0796/G0797 (Mfd. Since 1/18)

Anchoring machinery to the floor prevents tipping
or shifting and reduces vibration that may occur
during operation, resulting in a machine that runs
slightly quieter and feels more solid.

If the machine will be installed in a commercial or
workplace setting, or if it is permanently connect­ed (hardwired) to the power supply, local codes
may require that it be anchored to the floor.

If not required by any local codes, fastening the
machine to the floor is an optional step. If you
choose not to do this with your machine, we rec­ommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.

Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a con­crete floor, because the anchors sit flush with the
floor surface, making it easy to unbolt and move
the machine later, if needed. However, anytime
local codes apply, you MUST follow the anchoring
methodology specified by the code.

Leveling

Anchoring to Floor

Leveling machinery helps precision components,
such as dovetail ways, remain straight and flat
during the lifespan of the machine. Components
on an unleveled machine may slowly twist due to
the dynamic loads placed on the machine during
operation.

Use metal shims between the base and the floor
when leveling the machine.

For best results, use a precision level that is at
least 12" long and sensitive enough to show a
distance movement when a 0.003" shim (approxi­mately the thickness of one sheet of standard
newspaper) is placed under one end of the level.

See Figure 13 for an example of a high precision
level provided by Grizzly.

6. Turn direction knob to left, slowly turn speed
dial clockwise to increase speed, then con­firm that table is moving to left.

7. Watch for table limit stop to hit limit switch
and turn power feed OFF, stopping table
movement.

During power feed operation, ball handles
spin rapidly when engaged. Always stay
clear of ball handles when using power
feed. Failure to do so could lead to entan­glement or impact injuries.

To test run power feed:

1. Make sure all tools, cables, and other items

are well clear of table movement and potential
direction of travel.

2. Refer to Operating X-Axis Power Feed
section, beginning on Page 31, to understand
how power feed, table locks, and limit switch
function.

3. Loosen table locks on front of table.

4. Plug power feed power cord into a grounded

110V power outlet.

8. Turn direction knob through neutral (middle)
position and all the way to the right. Table
should begin moving to the right.

9. Confirm that table stops moving when limit
stop presses against limit switch plunger.

10. Move direction knob to neutral (middle) posi­tion, turn speed dial to lowest setting, and
press OFF button.

Positioning Table

The mill table moves in three directions, as illus­trated in Figure 22:

• X-axis (longitudinal)

• Y-axis (cross)

• Z-axis (vertical)

These movements are controlled by rotating the
X- and Y-axis ball handles and the Z-axis crank.
Additionally, the table can be moved along the
X-axis with the power feed.

Spindle downfeed movement on the mill is con­trolled by three mechanisms: 1) The coarse
downfeed lever, 2) the fine downfeed handwheel,
and 3) the auto-downfeed system.

Downfeed Controls

Use Figure 39 and the following descriptions to
become familiar with the spindle downfeed con­trols.

Setting Downfeed Stop

The downfeed stop (see Figure 39) sets the depth
of spindle travel for repeat operations. The upper
edge of the downfeed stop aligns with marks on
the downfeed scale to help you set the approxi­mate depth, however the downfeed scale func­tions as a general guide only, and is not intended
for low-tolerance, precision results.

To set the downfeed stop, rotate stop until upper
edge aligns with desired depth indicated on
scale (see Figure 39), then tighten locking wheel
against stop to secure it.

Auto-Downfeed

(Engaged)

Using Coarse Downfeed

Coarse downfeed is typically used for drilling,
because it allows you to quickly lower the spindle
with varying speed/pressure, and it automati­cally retracts the spindle to the top position when
released.

Note: To maintain control of the upward spindle
travel and the rotating bit in your workpiece,
always continue holding the lever until the spindle
returns to the top position. Letting go of the lever
too soon will cause the spindle to retract too
quickly and slam up into the headstock.

To use coarse downfeed:

3. Make sure pin of coarse downfeed lever

hub is engaged with one of the detents on
downfeed sleeve, and loosen quill lock lever
(see Figure 41).

4. Rotate coarse downfeed lever around hub to
control spindle depth.

Auto-Downfeed

(Engaged)

Fine downfeed is used for precise Z-axis posi­tioning of a cutter or end-mill when milling a flat
surface across the face of a workpiece. In order
to ensure the milled surface remains flat, the quill
lock lever should be locked after each adjustment
to ensure the spindle height cannot move until the
entire milling operation is complete.

To use fine downfeed:

1. DISCONNECT MACHINE FROM POWER!

2. Make sure spindle is completely stopped,

then pull downfeed selector knob out and
rotate it until it seats in manual (disengaged)
position (see Figure 40 on Page 38).

Note: It may be necessary to turn the spindle

by hand as you move the selector to enable
the gears to mesh.

3. Set auto-downfeed direction pin (see Figure
39 on Page 37) in neutral (middle) position

to disengage fine downfeed handwheel from
auto-downfeed gears.

4. Use coarse downfeed lever to lower spindle

slightly until you can pull fine/auto downfeed
clutch lever (see Figure 39 on Page 37) to
the left so it locks in place.

Using Auto-Downfeed

When using the auto-downfeed system, the spin­dle will move in the direction you choose with the
auto-downfeed direction pin. When the quill dog
reaches the top or meets the downfeed stop, the
downfeed clutch lever will release. Then, if the
spindle was traveling upward, the movement will
simply stop. If the spindle was traveling down­ward, then the spindle will move back to the top
at a rate controlled by the return spring on the left
side of the head.

To use auto-downfeed:

1. Make sure spindle is completely stopped.

2. Pull downfeed selector knob out, then rotate

it clockwise until knob pin seats in auto-down­feed (engaged) detent (see Figure 42).

Note: It may be necessary to turn the spindle

by hand as you move the selector to enable
the gears to mesh.

Figure 39 on Page 37) in center of handwheel

for spindle travel that is correct for your
operation. If necessary, rock fine downfeed
handwheel back-and-forth to move pin all the
way in or out.

Note: The direction pin has three positions:

1) In for one downfeed direction, 2) middle
for neutral or no movement, and 3) out for
the reverse direction. The direction of spindle
travel for the in and out positions is relative to
the direction of spindle rotation. Keep in mind
that spindle rotation and downfeed direction
will reverse when the spindle speed range is
changed.

5. Make sure fine/auto downfeed clutch lever
is all the way to right in disengaged position
(see Figure 43) so that spindle will not travel

when rotation is started.

6. Set mill for correct spindle speed, then begin
spindle rotation.

ALWAYS start spindle rotation before using
auto-downfeed to avoid risk of gear damage.

7. Select one of the three downfeed rates by

pulling knob of auto-downfeed rate selector
out, position selector over appropriate detent,
then release knob. Make sure pin is firmly
seated by attempting to move selector with­out pulling knob out.

Note: Refer to the illustration in Figure 44

SECTION 6: MAINTENANCE

To reduce risk of shock or
accidental startup, always
disconnect machine from

power before adjustments,
maintenance, or service.

Schedule

For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.

Ongoing

To help minimize your risk of injury and maintain
proper machine operation, if you ever observe
any of the items below shut the machine down
immediately, disconnect it from power, and fix the
problem before continuing operations.

• Loose mounting bolts or fasteners.

• Worn, frayed, cracked, or damaged wires.

• Missing belt guards.

• Reduction in braking speed or efficiency.

• Any other unsafe condition.

Daily, After Operations

• Disconnect the machine from power.

• Vacuum/clean all chips and swarf from table,
slides, and base.

• Wipe down all unpainted or machined sur­faces with a good quality rust preventative.

Cleaning &

Protecting

Regular cleaning is one of the most important
steps in taking good care of this mill. Each opera­tor is responsible for cleaning the machine imme­diately after using it or at the end of the day. We
recommend that the cleaning routine be planned
into the workflow schedule, so that adequate time
is set aside to do the job right.

Typically, the easiest way to clean swarf from the
ways and table is to use a wet/dry shop vacuum
that is dedicated for this purpose only. The small
chips leftover after vacuuming can be wiped up
with a slightly oiled rag. Avoid using compressed
air to blow off chips, as this may drive them deep­er into moving surfaces and could cause sharp
chips to fly into your face or hands.

Before Beginning Operations

• Turn the spindle direction switch to the
OFF(middle) position to prevent spindle start­up when connected to power (see Page 26).

• Move the fine/auto downfeed clutch lever to

the right (disengaged) position to prevent the
spindle from unexpectedly auto-downfeeding
when rotation is started (see Figure 43 on

Page 40).

• Make sure the X-axis power feed is turned

OFF to prevent unintentional table movement
when connected to power (see Page 31).

• Perform lubrications tasks as directed in the

Lubrication section on Page 47.

• Check table movement in all three axis direc-

tions for loose/tight gibs. Adjust the gibs if
necessary (see Page 54).

-46-

Besides the ways and elevation leadscrew, all
other unpainted and machined surfaces should
be wiped down daily to keep them rust-free and in
top condition. This includes any surface that could
be vulnerable to rust if left unprotected (this espe­cially includes any parts that may be exposed to
water soluble cutting fluids). Typically with these
parts, a thin film of oil is all that is necessary for
protection.

Keep tables rust-free with ISO 68 way oil.

Model G0796/G0797 (Mfd. Since 1/18)

Lubrication

The mill has numerous moving metal-to-metal
contacts that require regular and proper lubrica­tion to ensure efficient and long-lasting operation,
and to protect your investment.

Other than the lubrication points covered in this
section, all other bearings are internally lubricated
and sealed at the factory. Simply leave them
alone unless they need to be replaced.

Failure to follow reasonable lubrication
practices as instructed in this manual for
the mill could lead to premature failure of
the mill and will void the warranty.

Quill

Oil Type ..... Model SB1365 or ISO 68 Equivalent

Before performing any lubrication task,
DISCONNECT MACHINE FROM POWER!

Important: Before adding lubricant, clean the
debris and grime from the oil cup or grease fitting
and the immediate area to prevent contamination
of the new lubricant.

Use the schedule and information in Figure 63
as a daily guide for lubrication tasks. Follow the
referenced sections on the following pages for
detailed instructions.

The following recommended lubrication
schedule is based on light to medium mill

Machine Storage

To avoid rust problems or corrosion damage, use
the following information to protect your invest­ment when storing the mill for any length of time.

• DISCONNECT MACHINE FROM POWER!

• Lubricate the mill as directed in the Lubrication
section beginning on Page 47.

Brass Bevel Gear

Figure 73. Power feed brass gear and

leadscrew alignment key.

6. Brush a light coat of grease on teeth of bevel
gear and smaller drive gear (see Figure 74).

Brass Bevel Gear

Drive Gear

Figure 74. Power feed brass bevel gear and

drive gear.

7. Make sure leadscrew alignment key is
installed, then align bevel gear keyway with
key as you slide gear onto leadscrew and
mesh its teeth with drive gear.

8. Align graduated dial ring keyway with key,
then slide it into position and secure it with
knurled retaining ring—do not overtighten.

• Thoroughly clean all unpainted, bare metal
surfaces, then coat them with a light weight
grease or rust preventative. Take care to
ensure these surfaces are completely cov­ered but that the grease or rust preventative
is kept off painted surfaces.

Note: If the machine will be out of service

for only a short period of time, use way oil or
a good grade of medium-weight machine oil
(not auto engine oil) in place of the grease or
rust preventative.

• Loosen the belts to prevent them from stretch­ing during storage. Post a reminder on the
mill that the belts need to be re-tensioned
before resuming operations.

• Cover and place the machine in a dry area
that is out of direct sunlight and away from
hazardous fumes, paint, solvents, or gas.
Fumes and sunlight can bleach or discolor
paint and plastic parts.

• At least once a month, start the mill and run
all gear-driven components for a few min­utes. This will keep the bearings, bushings,
gears, and shafts well lubricated and pro­tected from corrosion, especially during the
winter months.

9. Replace spacer, detent sleeve, compression
spring, ball handle, and ball handle nut in
reverse order from removal.

10. Manually move table with power feed ball
handle to check gear movement and to dis­tribute grease on gears. If movement is not
smooth, repeat Steps 2–8 until it is.

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.

Table Gib &

Adjustment Screw

Figure 75. Table gib and adjustment screw

underneath left side of table.

Gibs are adjusted with a screw on each end of
the gib, that move the tapered gib back-and-forth
to increase or decrease the friction pressure
between the sliding surfaces. The process of
properly adjusting the gibs requires trial-and-error
and patience.

Refer to Figures 75–77 to identify the locations of
the table, saddle, and knee gibs, and one of the
two adjustment screws for each.

Note: It will be necessary to remove small parts,
such as way wipers and covers, to access the gib
adjustment screws.

Tools Needed Qty

Screwdriver Phillips, Flat Head .....................1 Ea

To adjust gibs:

1. DISCONNECT MACHINE FROM POWER!

2. Make sure all table/knee locks are loose.

Adjusting Leadscrew

Backlash

Leadscrew backlash is the amount of motion or
"play" in leadscrew rotation before the attached
device begins to move. Leadscrews will always
have a certain amount of backlash that will
increase with normal wear.

Generally, 0.005"–0.010" leadscrew backlash is
acceptable to ensure smooth movement and
reduce the risk of premature thread wear. However,
if you find it necessary to adjust leadscrew back­lash, perform the procedures listed below.

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.

Note: A precision-ground plate can be substi­tuted 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.

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 82.

Spindle

Z-Axis

Y-Axis

Figure 82. Spindle Z-axis perpendicular to the

table X- and Y-axis.

We encourage you to research the many varia­tions 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.

2. Prepare mill for tramming by performing fol­lowing 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 any table, knee, quill, or ram locks

that should be tight during the intended
milling operation.

3. Place parallel block underneath spindle.

4. Install indicator holder in spindle or on quill,

then mount indicator so that point is as paral­lel to block as possible (see Figure 83).

Spindle

Dial Test

Indicator

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 tram­ming 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 84.

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.

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.

8. Place parallel block directly under spindle
and across width of table, as illustrated in
Figure 85.

Table (Top View)

Parallel Block

Indicator Spindle

Figure 84. Parallel block and indicator positioned

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.

6. Rotate spindle by hand so that indicator point
rests on one end of parallel block, as illus­trated in Figures 83–84, then zero the dial.

7. Rotate spindle so that indicator point rests

in same manner on other end of block, then
read dial.

— 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.

9. Rotate spindle so indicator point rests on par­allel bar, as illustrated in Figure 85, then zero
the dial.

10. Rotate spindle so that indicator point rests on
other end of bar in same manner, then read
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.

— If the indicator dial has moved from zero

beyond the acceptable variance, you
will need to compensate for that amount
by tilting the head forward or backward.
Repeat Steps 9–10 until you are satisfied
with the spindle axis alignment along the
table Y-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.

Replacing Belts &

Brake Shoes

Replacing a broken belt or the spindle brake
shoes requires removing the motor and part of the
headstock. These components are very heavy,
and you will need the assistance of a helper to
remove them.

Since the procedure for replacing the spindle
brake shoes involves removing many of these
same components as in a belt replacement, it is a
good idea to check the brake shoes whenever you
replace a belt, and replace the shoes if necessary.
