Machine Description
The Model G0746 is a 20" x 60" lathe. The Model
G0749 is a 16" x 40" lathe. The main difference
between the two models is the G0746 has a
larger spindle bore, swing over bed, and distance
between centers than the G0749.
The Models G0746 and G0749 feature thick castings and super heavy-duty construction, making
them extremely rigid and solid. We equipped
both models with a 10 HP, 220V, 3-phase spindle
motor, massive tailstock, steady rest, and follow
rest—ensuring these lathes are a reliable workhorse in demanding machine shops that turn big
and heavy workpieces.

long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and 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.

Additional Safety for Metal Lathes
Never attempt to slow or stop the lathe spindle with
SPEED RATES. Operating the lathe at the wrong
speed can cause nearby parts to break or the
workpiece to come loose, which will result in dangerous projectiles that could cause severe impact
injuries. Large or non-concentric workpieces must
be turned at slow speeds. Always use the appropriate feed and speed rates.
CHUCK KEY SAFETY. A chuck key left in the
chuck can become a deadly projectile when the
spindle is started. Always remove the chuck key
after using it. Develop a habit of not taking your
hand off of a chuck key unless it is away from the
machine.
SAFE CLEARANCES. Workpieces that crash
into other components on the lathe may throw
dangerous projectiles in all directions, leading to
impact injury and damaged equipment. Before
starting the spindle, make sure the workpiece has
adequate clearance by hand-rotating it through its
entire range of motion. Also, check the tool and
tool post clearance, chuck clearance, and saddle
clearance.
LONG STOCK SAFETY. Long stock can whip
violently if not properly supported, causing serious
impact injury and damage to the lathe. Reduce this
risk by supporting any stock that extends from the
chuck/headstock more than three times its own
diameter. Always turn long stock at slow speeds.
SECURING WORKPIECE. An improperly secured
workpiece can fly off the lathe spindle with deadly
force, which can result in a severe impact injury.
Make sure the workpiece is properly secured in the
chuck or faceplate before starting the lathe.
CHUCKS. Chucks are very heavy and difficult to
grasp, which can lead to crushed fingers or hands
if mishandled. Get assistance when handling
chucks to reduce this risk. Protect your hands and
the precision-ground ways by using a chuck cradle
or piece of plywood over the ways of the lathe
when servicing chucks. Use lifting devices when
necessary.
CLEARING CHIPS. Metal chips can easily cut
bare skin—even through a piece of cloth. Avoid
clearing chips by hand or with a rag. Use a brush
or vacuum to clear metal chips.
STOPPING SPINDLE BY HAND. Stopping the
spindle by putting your hand on the workpiece
or chuck creates an extreme risk of entanglement, impact, crushing, friction, or cutting hazards.
your hand. Allow the spindle to come to a stop on
its own or use the brake.
CRASHES. Aggressively driving the cutting tool or
other lathe components into the chuck may cause
an explosion of metal fragments, which can result
in severe impact injuries and major damage to
the lathe. Reduce this risk by releasing automatic
feeds after use, not leaving lathe unattended, and
checking clearances before starting the lathe.
Make sure no part of the tool, tool holder, compound rest, cross slide, or carriage will contact the
chuck during operation.
COOLANT SAFETY. Coolant is a very poisonous biohazard that can cause personal injury from
skin contact alone. Incorrectly positioned coolant
nozzles can splash on the operator or the floor,
resulting in an exposure or slipping hazard. To
decrease your risk, change coolant regularly and
position the nozzle where it will not splash or end
up on the floor.
TOOL SELECTION. Cutting with an incorrect or
dull tool increases the risk of accidental injury due
to the extra force required for the operation, which
increases the risk of breaking or dislodging components that can cause small shards of metal to
become dangerous projectiles. Always select the
right cutter for the job and make sure it is sharp. A
correct, sharp tool decreases strain and provides
a better finish.

Model G0746/G0749 (Mfg. Since 3/13)
Additional Chuck Safety
ENTANGLEMENT. Entanglement with a rotat-
ing chuck can lead to death, amputation, broken
bones, or other serious injury. Never attempt to
slow or stop the lathe chuck by hand, and always
roll up long sleeves, tie back long hair, and remove
any jewelry or loose apparel BEFORE operating.
CHUCK SPEED RATING. Excessive spindle
speeds greatly increase the risk of the workpiece
or chuck being thrown from the machine with
deadly force. Never use spindle speeds faster than
the chuck RPM rating or the safe limits of your
workpiece.
USING CORRECT EQUIPMENT. Many workpieces can only be safely turned in a lathe if additional
support equipment, such as a tailstock or steady/
follow rest, is used. If the operation is too hazardous to be completed with the lathe or existing
equipment, the operator must have enough experience to know when to use a different machine or
find a safer way.
TRAINED OPERATORS ONLY. Using a chuck
incorrectly can result in workpieces coming loose
at high speeds and striking the operator or bystanders with deadly force. To reduce the risk of this hazard, read and understand this document and seek
additional training from an experienced chuck user
before using a chuck.
CHUCK CAPACITY. Avoid exceeding the capacity
of the chuck by clamping an oversized workpiece.
If the workpiece is too large to safely clamp with
the chuck, use a faceplate or a larger chuck if possible. Otherwise, the workpiece could be thrown
from the lathe during operation, resulting in serious
impact injury or death.
CLAMPING FORCE. Inadequate clamping force
can lead to the workpiece being thrown from the
chuck and striking the operator or bystanders.
Maximum clamping force is achieved when the
chuck is properly maintained and lubricated, all
jaws are fully engaged with the workpiece, and
the maximum chuck clamping diameter is not
exceeded.
PROPER MAINTENANCE. All chucks must be
properly maintained and lubricated to achieve
maximum clamping force and withstand the rigors
of centrifugal force. To reduce the risk of a thrown
workpiece, follow all maintenance intervals and
instructions in this document.
DISCONNECT POWER. Serious entanglement or
impact injuries could occur if the lathe is started
while you are adjusting, servicing, or installing the
chuck. Always disconnect the lathe from power
before performing these procedures.

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.)

codes in your area.
Model G0746/G0749 (Mfg. Since 3/13)
Connection Type
A permanently connected (hardwired) power supply is typically installed with wires running through
mounted and secured conduit. A disconnecting
means, such as a locking switch (see following
figure), must be provided to allow the machine
to be disconnected (isolated) from the power
supply when required. This installation must be
performed by an electrician in accordance with all
applicable electrical codes and ordinances.
In the event of a malfunction or breakdown,
grounding provides a path of least resistance
for electrical current to reduce the risk of electric
shock. A permanently connected machine must
be connected to a grounded metal permanent wir
ing system; or to a system having an equipmentgrounding conductor. All grounds must be verified
and rated for the electrical requirements of the
machine. Improper grounding can increase the
risk of electric shock!
Since this machine must be permanently connected to the power supply, an extension cord
cannot be used.

lifting machine or some of
its parts. To reduce this risk,
get help from other people
and use a fork lift (or other
lifting equipment) rated for
weight of this machine.
Do not attempt to lift or move this lathe without
using the proper lifting equipment (such as forklift
or crane) or the necessary assistance from other
people. Each piece of lifting equipment must be
rated for at least 6800 lbs to support dynamic
loads that may be applied while lifting. Refer to
Needed for Setup on Page 20 for details.
6. Insert round steel bar stock through the four
lifting holes (see Figure 16).
Note: To properly support the lathe and
avoid damaging lathe components, bar stock
should be at least 1" diameter thick and 49"
long, so it projects 14" from both sides of the
lathe when installed.

To lift and move the lathe:
1. Remove the shipping crate top and sides,
then remove the small components from the
shipping pallet.
2. Move the lathe to its prepared location while
it is still attached to the shipping pallet.
3. Unbolt the lathe from the shipping pallet.
4. To balance the load for lifting, move the
tailstock and carriage to the extreme right
end of the bedway, then lock them in place.
Note: Before attempting to move the car-
riage, make sure the carriage lock is loose,
the half nut is disengaged, and the power
feed is disengaged (feed selection lever).
5. Remove the splash guard so it does not get
damaged when the lathe is raised.
Figure 16. Example of lathe setup for lifting.
7. Attach the lifting straps to the bar stock and
the power lifting equipment (see Figure 16).
Make sure there is enough space between
the straps and the control rod, feed rod,
leadscrew and electrical cabinet to prevent
putting pressure on these components when
lifting.
8. Raise the lathe a couple of inches and check
the balance of the load. Have two other people carefully steady the lathe to help prevent
it from swinging.
— If the load is not safely balanced, immedi-
ately lower the lathe and resolve the issue
before attempting to lift it again.
9. Raise the lathe enough to clear the shipping
pallet and carefully remove the pallet.
— If you plan to use the included leveling
bolts and hex nuts to level the lathe, install
them now.

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.
Anchoring to Floor Leveling
For accurate turning results and to prevent
warping the cast iron bed and ways, the
lathe bedways MUST be leveled from sideto-side and from front-to-back on both ends.
Re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
Anchoring to Concrete Floors
operation.
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.

For best results, use a precision level that is at
least 12" long and sensitive enough to show a
distinct movement when a 0.003" shim (approximately the thickness of one sheet of standard
newspaper) is placed under one end of the level.
See the figure below for an example of a high
precision level offered by Grizzly.

—If using the included leveling pads (see
Figure 19), thread the leveling bolts with
the hex nuts into the bottom of the stand,
place the pads under the bolts, then adjust
them to level the machine.

With the exception of the carriage handle and
cross slide handwheel, the lathe is shipped fully
assembled.

remove the coolant motor cover.
Use a 5mm hex wrench to thread the carriage
handle into the carriage handwheel.
Slide the cross slide handwheel onto the shaft

Power Connection
Electrocution or fire
may occur if machine is
ungrounded, incorrectly
connected to power, or
connected to an undersized
circuit. Use an electrician
or a qualified service
personnel to ensure a safe
power connection.
The headstock, gearbox, and apron oil reservoirs
must have the proper amount of oil in them before
the lathe can be operated.
Damage caused to the bearings and gears from
running the lathe without oil in the reservoirs
will not be covered under warranty. Refer to the
Lubrication section, beginning on Page 67, for
checking and adding oil.
In addition to the reservoirs, we also recommend
that you lubricate all other points on the machine
at this time. To do this, follow the steps provided in
the maintenance schedule on Page 66.
Note: If this lathe was shipped with oil in the res-
ervoirs, do not change that oil until after the Test
Run and Spindle Break-In procedures.
Adding Coolant
Add the coolant of your choice now. For detailed
instructions on where the coolant tank is located
and how to add fluid, refer to Coolant System
Service on Page 72.
Before the machine can be connected to the
power source, an electrical circuit and connection
device must be prepared according to the circuit
requirements on the Page 18, and the machine
must be completely setup and installed in its permanent location.
Once the lathe is connected to the power supply,
the disconnect switch that is installed by the electrician (as recommended) is the primary means
for disconnecting or connecting the machine to
the power source.
Note About Phase Converters: Due to the
startup load from this machine, we do not recommend using a static phase converter to create
3-phase power—as it can quickly decrease the
life of electrical components on this machine. If
you must use a phase converter, only use a rotary
phase converter. Only connect the manufactured
leg or "wild wire" to the L3 terminal (see location in Figure 24 on Page 28). The L3 terminal
can handle power fluctuation because it is wired
directly to the motor.
Model G0746/G0749 (Mfg. Since 3/13)

Before subjecting the spindle to operational loads,
it is essential to complete the break-in process.
This helps ensure maximum life of spindle bearings and other precision components by thoroughly lubricating them before placing them under
load.
After spindle break-in is complete, we recommend
changing headstock and gearbox oil to remove
any metal particles or debris that are present from
the assembly and break-in process.
The break-in must be performed in succession
with the

Chuck & Plate
This lathe is equipped with a D1-type spindle
nose. This type of spindle uses camlocks that are
adjusted with a chuck key to securely mount a
chuck or faceplate with repeatable precision and
ease.
This lathe ships with the 3-jaw chuck installed.
This is a scroll-type chuck where all three jaws
move in unison when the chuck key is used.
The included 4-jaw chuck features independent
jaws, which are used for square or unevenlyshaped stock, and to mount work that needs to be
adjusted to near zero total indicated runout.
The included faceplate has slots for T-bolts that
hold standard or custom clamping hardware. With
the correct clamping hardware, a faceplate offers
a wide range of uses, including machining nonconcentric workpieces, straight turning between
centers, off-center turning, and boring.

The faceplate included with your lathe can be
used for a wide range of operations, including
machining non-concentric workpieces, straight
turning between centers, off-center turning, and
boring.
The tools needed for mounting a workpiece will
vary depending on the type of setup you have.
Drive Plate
Refer to the prior Chuck Installation and Chuck

A carbide-tipped dead center (not included) can
better withstand the effects of friction than a typical dead center and is best used in the tailstock
where the workpiece will rotate against it. The tip
of a dead center must be generously lubricated
during the operation to avoid premature wear and
maximize smooth operation. Using low spindle
speeds will also reduce the heat and wear from
friction.
Use the dead center in the spindle for operations
where the workpiece rotates with the center and
does not generate friction.

Spindle Speed
Using the correct spindle speed is important for
getting safe and satisfactory results, as well as
maximizing tool life.
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 lathe
controls 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 workpiece, as noted in the formula shown in
Figure 70.
Setting Spindle Speed
The spindle range lever and spindle speed lever,
shown in Figure 71, are used to select one of the
15 spindle speeds.

Figure 70. Spindle speed formula for lathes.
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.
To avoid damaging gears, ALWAYS make
sure the spindle is completely stopped
BEFORE moving the spindle speed levers.

Both the carriage and cross slide have power feed
capability when the carriage is engaged with the
feed rod. The rate that these components move
per revolution of the feed rod is controlled by the
quick-change gearbox lever and dial positions
and the end gear configuration.
The feed per revolution and the spindle speed
must be considered together—this is the feed
rate. The sources you use to determine the optimum spindle speed for an operation will also
provide the optimal feed to use with that spindle
speed.
Often, the experienced machinist will use the
feeds and speeds given in their reference charts
or web calculators as a starting point, then make
minor adjustments to the feed rate (and sometimes spindle speed) to achieve the best results.
The carriage can alternately be driven by the
leadscrew for threading operations. However, this
section only covers the use of the power feed
option for the carriage and cross slide components for non-threading operations. To learn how
to power the carriage for threading operations,
refer to Threading on Page 57.

If the feed selection lever and the half nut
are engaged at the same time, machine
damage could occur. Even though there is
a lock-out device to prevent this, it could
break if forced.

To avoid damaging the lathe, ALWAYS make
sure the spindle is completely stopped
BEFORE using the headstock controls to
make changes.

SECTION 6: MAINTENANCE
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious personal injury.
Schedule
Ongoing
To maintain a low risk of injury and proper
machine operation, if you ever observe any of the
items below, shut down the machine immediately
and fix the problem before continuing operations:
• Loose mounting bolts or fasteners.
• Worn, frayed, cracked, or damaged wires.
• Guards or covers removed.
• EMERGENCY STOP button not working correctly or not requiring you to reset it before
starting the machine again.
• Oil level not visible in the sight glasses.
• Damaged or malfunctioning components.
Daily, After Operations
• Press the EMERGENCY STOP button (to
prevent accidental startup).
• Vacuum/clean all chips and swarf from bed,
slides.
• Wipe down all unpainted or machined surfaces with an oiled rag.
Every 50 Hours
• Lubricate end gears (Page 71).
Every 1000 Operating Hours
• Change the headstock oil (Page 67).
• Change the gearbox oil (Page 68).
• Change the apron oil (Page 69).
Annually
• Check/level bedway (Page 27).
Cleaning/Protecting
Because of its importance, we recommend that
the cleaning routine be planned into the workflow
schedule.
Daily, Before Operations
• Check/add headstock oil (Page 67).
• Check/add gearbox oil (Page 68).
• Check/add apron oil (Page 69).
• Lubricate the bedways (Page 69).
• Add oil to the ball oilers (Page 70).
• Clean/lubricate the leadscrew (Page 69).
• Disengage the feed lever and feed selection
lever on the apron (to prevent crashes upon
startup).
• Ensure carriage lock bolt is loose.
-66-
Typically, the easiest way to clean swarf from the
machine is to use a wet/dry shop vacuum that is
dedicated for this purpose. The small chips left
over 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
the moving surfaces or cause sharp chips to fly
into your face or hands.
All unpainted and machined surfaces should be
wiped down daily to keep them rust free and in
top condition. This includes any surface that is
vulnerable to rust if left unprotected (especially
parts that are exposed to water soluble cutting
fluid). Use a quality ISO 68 way oil (see Page 64
for offerings from Grizzly) to prevent corrosion.

Lubrication
Use the information in the charts below as a daily
guide for lubrication tasks. We recommend using
Grizzly T23962 (ISO 68) or T23963 (ISO 32) lubricants (see Accessories, Page 64) for most of the
lubrication tasks.
NOTICE
The recommended lubrication is based on
light-to-medium usage. Keeping in mind
that lubrication helps to protect the value
and operation of the lathe, these lubrication
tasks may need to be performed more frequently than recommended here, depending on usage.

To use the one-shot oiler, pull the pump lever six
times. The pump draws oil from the apron reservoir and then forces it through drilled passages in
the carriage and onto the bedways.
Repeat this process while moving the carriage
through its full range of movement to distribute oil
along the bedways.
Lubricate the bedways before and after operating
the lathe. If the lathe is in a moist or dirty environment, increase the lubrication interval.
Check the apron oil level through the sight glass
before using the one-shot oiler to make sure the
reservoir has enough oil.

Model G0746/G0749 (Mfg. Since 3/13)
Before lubricating the leadscrew (see Figure
116), clean it first with mineral spirits. A stiff brush
works well to help clean out the threads. Make
sure to move the carriage out of the way, so you
can clean the entire length of the leadscrew.
Apply a thin coat of oil along the length of the
leadscrew. Use a stiff brush to make sure the oil
is applied evenly and down into the threads.
Note: In some environments, abrasive material
can become caught in the leadscrew lubricant and
drawn into the half nut. In this case, lubricate the
leadscrew with a quality dry lubricant.

This lathe has 11 ball oilers that should be oiled
on a daily basis before beginning operation. Refer
to Figures 117–121 for their locations.
Ball Oilers
Proper lubrication of ball oilers is done with a
pump-type oil can that has a plastic or rubberized cone tip. 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.
Lubricate the ball oilers before and after machine
use, and more frequently under heavy use. When
lubricating ball oilers, first clean the outside surface to remove any dust or grime. Push the rubber or plastic tip of the oil can nozzle against the
ball oiler to create a hydraulic seal, then pump the
oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, keep
pumping the oil can until the oil runs clear. When
finished, wipe away any excess oil.

End Gears
Grease Type ........ T23964 or NLGI#2 Equivalent
Lubrication ................. Every 50 Operating Hours
The end gears, shown in Figure 122, should
always have a thin coat of heavy grease to
minimize corrosion, noise, and wear. Wipe away
excess grease that could be thrown onto the
V-belts and reduce optimal power transmission
from the motor.
Figure 122. End gears.
Lubricating
1. DISCONNECT LATHE FROM POWER!
2. Open the end-gear cover and remove all the
end gears shown in Figure 122.
3. Clean the end gears thoroughly with mineral
spirits to remove the old grease. Use a small
brush if necessary to clean between the
teeth.
4. Clean the shafts, and wipe away any grease
splatters in the vicinity and on the inside of
the end-gear cover.
5. Using a clean brush, apply a thin layer of
grease on the gears. Make sure to get grease
between the gear teeth, but do not fill the
teeth valleys.
6. Install the end gears and mesh them together
with an approximate 0.002"–0.004" backlash.
Once the gears are meshed together, apply
a small dab of grease between them where
they mesh together—this grease will be distributed when the gears rotate and re-coat
any areas scraped off during installation.
Handling & Care
Make sure to clean and lubricate any gears you
install or change. Be very careful during handling
and storage—the grease coating on the gears will
easily pickup dirt or debris, which can then spread
to the other gears and increase the rate of wear.
Make sure the end-gear cover remains closed
whenever possible to keep the gears free of dust
or debris from the outside environment.
7. Close the end-gear cover before re-connecting the lathe to power.

Coolant System
Service
The coolant system consists of a fluid tank, pump,
and flexible nozzle. The pump pulls fluid from the
tank and sends it to the valve, which controls the
flow of coolant to the nozzle. As the fluid leaves
the work area, it drains back into the tank through
the chip drawer where the swarf is screened out.
Although most swarf from machining operations is
screened out of the coolant before it returns to the
tank, small particles will accumulate in the bottom
of the tank in the form of sludge. To prevent this
sludge from being pulled into the pump and damaging it, the pump’s intake is positioned a couple
inches from the bottom of the tank. This works
well when the tank is regularly cleaned; however, if too much sludge is allowed to accumulate
before the tank is cleaned, the pump will inevitably
begin sucking it up.
Use Figures 123–124 to identify the locations of
the coolant system controls and components.

Hazards
As coolant ages and gets used, dangerous
microbes can proliferate and create a biological
hazard. The risk of exposure to this hazard can
be greatly reduced by replacing the old fluid on a
monthly basis, or as indicated by the fluid manufacturer.
The important thing to keep in mind when working with the coolant is to minimize exposure to
your skin, eyes, and lungs by wearing the proper
PPE (Personal Protective Equipment), such as
long-sleeve waterproof gloves, protective clothing,
splash-resistant safety goggles, and a NIOSHapproved respirator.
BIOLOGICAL & POISON
HAZARD!
Use the correct personal protection equipment
when handling coolant.
Follow federal, state,
and fluid manufacturer

1. Position the coolant nozzle over the back of
the back splash so that it is pointing behind
the lathe.
2. Place the 5-gallon bucket behind the lathe
and under the coolant nozzle. Have another
person hold the bucket up to the nozzle to
prevent coolant from splashing out.
3. Turn the coolant pump ON and pump the old
fluid out of the reservoir. Turn the pump OFF
immediately after the fluid stops flowing.
Running the coolant pump longer than
necessary for this procedure without
adequate fluid in the tank may permanently
damage it, which will not be covered under
warranty.
4. DISCONNECT LATHE FROM POWER!
5. Remove the access cover from the side of
the right stand, then slide the tank out.
3. Pour coolant into the tank until it is approximately 1" from the top.
4. Slide the tank back into the cabinet and
replace the access cover.
Changing Coolant
When you replace the old coolant, take the time
to thoroughly clean out the chip drawer and fluid
tank. The entire job only takes about a
when you are prepared with the proper materials and tools. Make sure to dispose of old fluid
according to federal, state, and fluid manufacturer's requirements.

long, so the tank can be removed and
dumped out without disconnecting them from
the tank. However, the drain tube (see Figure
124 on Page 72) may come out of the tank
when you empty it.
6. Pour the remaining coolant into the 5-gallon
bucket and close the lid.
7. Clean all the sludge out of the bottom of the
tank and then flush it clean. Use the second
bucket to hold the waste and make sure to
seal the lid closed when done.
Dispose of the old coolant and swarf accord-
ing to federal, state, and fluid manufacturer's
requirements.

8. Slide the tank partially into the base and
insert the drain tube into the tank if it came
out earlier.
Tip: Leave one or more magnets at the bot-
tom of the tank to collect metal chips and
make cleanup easier next time. This will also
help keep small metal chips out of the pump.
9. Refill the tank with new coolant, then slide it
completely into the base.
10. Replace the access cover panel.
5. Lubricate the machine as outlined in the
lubrication section. Be sure to use an oil can
to purge all ball oilers and oil passages with
fresh oil.
6. Loosen or remove the V-belts so they do not
become stretched during the storage period.
(Be sure to place a maintenance note near
the power button as a reminder that the belts
have been loosened or removed.)
7. Place a few moisture absorbing desiccant
packs inside of the electrical box.
11. Re-connect the lathe to power and point the
nozzle into the chip drawer.
12. Reset the EMERGENCY STOP button.
13. Turn the coolant pump ON to verify that fluid
cycles properly, then turn it OFF.
Machine Storage
To prevent the development of rust and corrosion,
the lathe must be properly prepared if it will be
stored for a long period of time. Doing this will
ensure the lathe remains in good condition for
later use.
Preparing Lathe for Storage
1. Run the lathe and bring all reservoirs to oper-
ating temperature, then drain and refill them
with clean oil.
2. Pump out the old coolant, then add a few
drops of way oil and blow out the lines with
compressed air.
8. Cover the lathe and place it 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.
9. Every few months, rotate by hand all geardriven components a few times in several
gear selections. This will keep the bearings,
bushings, gears, and shafts well lubricated
and protected from corrosion—especially
during the winter months.
Slide the carriage, micrometer stop, tailstock,
and steady rest down the lathe bed to make
sure that way spotting is not beginning to
occur.
Bringing Lathe Out of Storage
1. Re-install the V-belts and re-tension them
(refer to Page 81) if you removed them for
storage purposes.
2. Remove the moisture-absorbing desiccant
packs from the electrical box.
3. Repeat the Test Run and Spindle Break-In
procedures, beginning on Page 31.
3. DISCONNECT LATHE FROM POWER!
4. Thoroughly clean all unpainted, bare metal
surfaces, then apply a liberal coat of way oil,
heavy grease, or rust preventative. Take care
to ensure these surfaces are completely covered but that the rust preventative or grease
is kept off of painted surfaces.

Backlash Adjustment
Backlash is the amount of free play felt while
changing rotation directions with the handwheel.
This can be adjusted on the compound rest and
cross slide leadscrews. Before beginning any
adjustment, make sure all associated components
are cleaned and lubricated and locks are loose.
To adjust the backlash, rock the handwheel back
and forth, and tighten the cap screw slowly until
the backlash is approximately 0.002"–0.003", as
indicated on the graduated dial.
If you end up adjusting the nut too tight, loosen
the cap screw, tap the compound rest a few times
with a rubber or wooden mallet, and turn the
handwheel slowly back and forth until it moves
freely—then try again.
When adjusting backlash, tighten the components
enough to remove backlash, but not so much that
the components bind the leadscrew, making it
hard to turn. Overtightening will cause excessive
wear to the sliding block and leadscrew.
Reducing backlash to less than 0.002" is
impractical and can lead to accelerated wear
of the wedge, nut, and leadscrew. Avoid the
temptation to overtighten the backlash set
screw while adjusting.
Compound Rest
Tools Needed: Qty
Hex Wrench 5mm .............................................. 1
The compound rest backlash is adjusted by
tightening the cap screw shown in Figure 126.
When the cap screw is tightened, the leadscrew

In general, loose gibs cause poor finishes and
tool chatter; however, over-tightened gibs cause
premature wear and make it difficult to turn the
handwheels.
To remove leadscrew end play:
1. DISCONNECT LATHE FROM POWER.
2. Loosen the outer spanner nut (see Figure
128).
Inner Spanner Nut
Leadscrew
Outer Spanner Nut
Figure 128. Leadscrew and spanner nuts.
3. Place a dial indicator on the end of the
leadscrew.
4. Rotate the carriage handwheel to move the
carriage toward the tailstock, then tighten
the inner spanner nut (see Figure 128) until
there is 0.001"–0.002" of end play.
5. Tighten the outer spanner nut until it is snug
against the inner spanner nut to secure the
setting.
The cross-slide and compound slide on this lathe
each use a long steel wedge called a gib that
is positioned between the component and its
dovetailed-ways. A gib screw at one end moves
the gib. Depending upon which direction the
gib moves, the space between the sliding ways
increases or decreases to control the rigidity of
the cross slide and compound slide.
Before adjusting the gibs, loosen the locks for the
devices so the gibs can slide freely during adjustment, then lubricate the ways.
The gib adjustment process usually requires
some trial-and-error. Repeat the process as necessary until you find the best balance between
loose and stiff movement. Most machinists find
that the ideal gib adjustment is one where a small
amount of drag or resistance is present, yet the
handwheels are still easy to move.

Saddle Gib
The saddle gib is located on the bottom of the
back edge of the cross slide (see Figure 132).
This gib is designed differently than the cross or
compound slide gibs. Instead of being a wedgeshaped plate, it is a flat bar. The gib pressure is
applied by four set screws. Hex nuts secure these
set screws in place, so they will not loosen during
operation.

Brake & Switch
As the brake lining wears, the foot pedal develops
more travel. If the brake band is not adjusted to
compensate for normal wear, the limit switch will
still turn the lathe OFF, but the spindle will not
stop as quickly. It is especially important that the
brake is kept properly adjusted so you can quickly
stop the spindle in an emergency.
Tools Needed: Qty

6. Close the end-gear cover, connect the lathe
to power, then test the brake pedal as follows:
a. Start the lathe, then lightly press the foot
pedal. The motor should shut OFF.
b. Push the foot pedal down further to stop
spindle rotation. You should not need to
press the pedal down completely to stop
the spindle, nor should the spindle keep
rotating. If either symptom occurs, repeat
Steps 5–6 until you are satisfied with the
brake performance.

space for turning large diameter parts.
The gap insert was installed, then ground flush
with the bed at the factory to ensure a precision
fit and alignment. Therefore, if the gap insert is
removed, it may be difficult to re-install with the
same degree of accuracy.

2. Tighten the two pre-load bolts so they no longer contact the headstock.
6. Mount a dial indicator with a magnetic base to
the top of the saddle to indicate alignment.
3. Use a slide hammer to remove the two dowel
pins from the gap insert.
4. Tap the outside of the gap insert with a dead
blow hammer to loosen it, then remove it.
Gap Installation
1. Use mineral spirits and a clean lint-free rag
to clean the mating surfaces of the gap, bed,
and ways. If necessary, stone the mating surfaces to remove scratches, dings, or burrs.
2. Wipe a thin layer of light machine oil on the
mating surfaces.
3. Place the gap insert into the gap and use a
dead-blow hammer to align the insert with the
lathe bed.
4. Lightly tap the dowel pins back into their
respective holes until they are seated. This
process will further help align the gap insert
and bed mating surfaces.
7. First test the peak of the two prisms of the
gap insert that the saddle rides on, then test
the flanks of the prisms.
8. Alternately tighten the gap bed cap screws
and tap the side of the gap insert into
alignment.
9. Inspect the gap alignment 24 hours later to
make sure the gap is still aligned. If necessary, loosen the gap bed cap screws and
repeat Steps 7–8 until the insert is properly
aligned.
10. Loosen the preload bolts until they contact
the headstock and resistance can be felt,
