End Gears

Safety Foot Brake

This lathe is equipped with a foot brake
(see Figure 7) to quickly stop the spindle instead
of allowing it to coast to a stop on its own. Pushing
the foot brake while the spindle is ON cuts power
to the motor and stops the spindle. After the foot
brake is used, the spindle lever must be returned
to the OFF (middle) position to reset the spindle
switches before re-starting spindle rotation.

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-

-10 -

Model G0824 (Mfd. Since 12/16)

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 Metal Lathes

Serious injury or death can occur from getting entangled in, crushed between, or struck by
rotating parts on a lathe! Unsecured tools or workpieces that fly loose from rotating objects
can also strike nearby operators with deadly force. To minimize the risk of getting hurt or killed,
anyone operating this machine MUST completely heed the hazards and warnings below.

CLOTHING, JEWELRY & LONG HAIR. Tie back

long hair, remove jewelry, and do not wear loose
clothing or gloves. These can easily get caught on
rotating parts and pull you into lathe.

ROTATING PA R TS. Always keep hands and body
at a safe distance from rotating parts—especially
those with projecting surfaces. Never hold any­thing against rotating workpiece, such as emery
cloth, that can pull you into lathe.

GUARDING. Guards and covers protect against
entanglement or flying objects. Always ensure they
are properly installed while machine is running.

ADJUSTMENT TOOLS. Remove all chuck keys,
wrenches, and adjustment tools before turning
lathe ON. A tool left on the lathe can become a
deadly projectile when spindle is started.

SAFE CLEARANCES. Before starting spindle,
verify workpiece has adequate clearance by hand­rotating it through its entire range of motion.

NEW SETUPS. Test each new setup by starting
spindle rotation at the lowest speed and standing
to the side of the lathe until workpiece reaches full
speed and you can verify safe rotation.

SPINDLE SPEEDS. Using spindle speeds that are
too fast for the workpiece or clamping equipment
can cause rotating parts to come loose and strike
nearby people with deadly force. Always use slow
spindle speeds with large or non-concentric work­pieces. Never exceed rated RPM of the chuck.

LONG STOCK SAFETY. Long stock can whip
violently if not properly supported. Always support
any stock that extends from the chuck/headstock
more than three times its own diameter.

CLEARING CHIPS. Metal chips can be razor
sharp. Avoid clearing them by hand or with a rag.
Use a brush or vacuum instead.

SECURE WORKPIECE. An improperly secured
workpiece can fly off spindle with deadly force.
Make sure workpiece is properly secured before
starting the lathe.

CHUCKS. Chucks can be heavy and difficult to
hold. During installation and removal, protect your
hands and precision bed ways by using a chuck
cradle or piece of plywood over the bed ways. Use
lifting equipment, as necessary, for large chucks.

STOPPING SPINDLE. Always allow spindle to
completely stop on its own, or use a brake, if
provided. Never put hands or another object on a
spinning workpiece to make it stop faster.

CRASHING. A serious explosion of metal parts
can occur if cutting tool or other lathe component
hits rotating chuck or a projecting part of work­piece. Resulting metal fragments can strike nearby
people and lathe will be seriously damaged. To
reduce risk of crashing, ALWAYS release automat­ic feeds after use, NEVER leave lathe unattended,
and CHECK all clearances before starting lathe.

COOLANT SAFETY. Coolant can become very
toxic through prolonged use and aging. To mini­mize toxicity, change coolant regularly. When
using, position nozzle properly to avoid splashing
operator or causing a slipping hazard on floor.

TOOL SELECTION. Cutting with incorrect or dull
tooling increases risk of injury from broken or dis­lodged components, or as a result of extra force
required for operation. Always use sharp tooling
that is right for the job.

SANDING/POLISHING. To reduce risk of entan­glement, never wrap emery cloth around rotating
workpiece. Instead, use emery cloth with the aid
of a tool or backing board.

MEASURING WORKPIECE. To reduce risk of
entanglement, never measure rotating workpieces.

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.

Model G0824 (Mfd. Since 12/16)

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.

This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:

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.)

Grounding Instructions

This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.

The power cord and plug specified under “Circuit
Requirements for 220V”
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 plug. If

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 can
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
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is 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)

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

6. Insert round steel bar stock through four lift-

ing holes (see Figure 17).

Note: To properly support the lathe and

avoid damaging lathe components, bar stock
should be at least 1

Anchoring to Floor

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.

Leveling

Lubricating Lathe

For accurate turning results and to prevent
warping or twisting of cast iron bed and
ways, lathe bedways MUST be leveled from
side to 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
operation.

If needed, use metal shims between the lathe bed
and chip pan when leveling the machine.

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.

GEARBOXES MUST

BE FILLED WITH OIL!

LATHE MAY NOT

HAVE OIL INCLUDED!

Refer to the Lubrication

Section in this Manual

for Recommended

Oil Type.

The headstock, quick-change 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 64, 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 63.

See the figure below for an example of a high
precision level offered by Grizzly.

Figure 21. Model H2683 Master Machinist's

Before subjecting the spindle to operational loads,
it is essential to complete the break-in process.
This helps maximize the 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
manual, as the steps in that procedure prepare
the lathe controls for the break-in process.

button, try to restart spindle rotation, as
instructed in Step 8. Spindle should not start.

— If spindle rotation does start with

Emergency Stop/RESET button pressed
in, the Emergency Stop/RESET button
safety is not operating correctly. This
safety feature must operate properly
before continuing operation. Use spindle
lever to stop lathe, disconnect it from
power, and call Tech Support for help.

10. Move spindle lever to OFF (middle) position,
and reset Emergency Stop/RESET button by
twisting it clockwise until it pops out.

11. Restart spindle rotation.

12. Step on foot brake. Spindle should come to a

quick stop.

— If brake pedal has no effect on lathe, push

Emergency Stop/RESET button and call
Tech Support for help.

13. Ensure work lamp functions properly.

14. Use cutting fluid pump switch on control
panel to start pump (see Figure 24 on Page

26), then open valve. Verify that cutting fluid

flows from nozzle, then turn pump OFF.

15. Press power button, then press and brief­ly hold the jog button (see Figure 24 on
Page 26), then release it. The spindle should
rotate when the jog button is pressed and
come to a complete stop when released.
