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.

Model G0784 (Mfd. since 03/15)

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].

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.)

Model G0784 (Mfd. since 03/15)

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.

Serious injury could occur if you connect

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

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.

See below for required space allocation.

Physical Environment

Lifting & Placing

get help from other people

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.

Anchoring to Floor

HEAVY LIFT!
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.

To move and place drill:

1. Place shipping crate near final machine

mounting location.

2. Remove top portion of crate from the shipping
pallet, place lifting slings around headstock
(see Figure 8), and attach them securely to
forklift (or other power lifting equipment).

Joining Drill Chuck

An arbor is included for the drill chuck that
comes with this machine. The following procedure
describes how to install the arbor in the chuck.

After the arbor is installed in the drill chuck, it
is very difficult to separate the assembly. If you
would like to use a different chuck in the future,
we recommend obtaining a new arbor.

Important: DO NOT install the drill chuck
and arbor assembly into the spindle until AFTER
the test run.

To join drill chuck and arbor:

1.

clean drill

2.

3.

4.

5. Attempt to separate drill chuck and arbor by
hand —if they separate, repeat Steps 3–4.

& Arbor

Use acetone or lacquer thinner to
chuck and arbor mating surfaces, especially
the bore.

Retract chuck jaws completely into chuck.

Insert small end of arbor into chuck.

Hold assembly by the arbor and tap chuck
onto a block of wood with medium force, as
illustrated below.

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.

Before the machine can be connected to the
power supply, there must be an electrical cir­cuit that meets the Circuit Requirements on
Page 10, and the correct plug must be installed
according to the instructions and wiring diagrams
provided by the plug manufacturer.

If the plug manufacturer did not include instruc­tions, the wiring of a generic NEMA 6-15 plug is
illustrated in the Wiring section on Page 35.

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.

Calculating Spindle Speed for Drilling

Using the Drill Bit Speed Chart

The chart shown in Figure 11 is intended as
a guide only. Always follow the manufacturer's
speed recommendations if provided with your
drill bits, cutters, or hole saws. Exceeding the
recommended speeds may be dangerous to the
operator.

The speeds shown here are intended to get you
started. The optimum speed will always depend
on various factors, including tool diameter, drilling
pressure, material hardness, material quality, and
desired finish.

Often, when drilling materials other than wood,
some type of lubrication is necessary.

SECTION 6: MAINTENANCE

Cleaning and

Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious person­al injur y.

Schedule

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

Daily Check

• Make sure drill is disconnected from power
when not in use.

• Check for loose mounting bolts.

• Make sure drill is clean and lubricated.

• Check for worn or damaged wires.

• Check for any other unsafe condition.

• Check belts for tension and wear.

Protecting

Sawdust, wood chips, and metal chips left on the
machine will invite oxidation and a gummy residue
buildup around the moving parts. Use a brush and
shop vacuum to remove chips and debris from the
working surfaces of the mill. Never blow off the
mill with compressed air, as this will force metal
chips deep into the mechanisms and may cause
injury to yourself or bystanders.

Remove any rust build-up from unpainted cast
iron surfaces of your mill and treat them with a
non-staining lubricant after cleaning.

Keep unpainted cast iron surfaces rust-free
with regular applications of products like G96
Gun Treatment, SLIPIT
Figure 31 and the Grizzly catalog or website).

Lubrication

V-Belts

For the quill, table, and column, an occasional
application of light machine oil is all that is neces­sary. For the quill and column racks, lubricate with
NLGI #2 grease every 90 days. Before applying
lubricant, clean off any dust or metal chips.

Your goal is to achieve adequate lubrication. Too
much lubrication will attract dirt and dust, which
could cause various parts of your machine to lose
their freedom of movement.

Downfeed Gears

Oil Ty p e ......Model T26685 or ISO 32 Equivalent

Oil Amount ......................................... Fill Oil Cup

Lubrication Frequency ...........8 Hrs. of Operation

Lift the oil cup cap (see Figure 32) to fill the cup
with oil. The oil will slowly drain into the downfeed
gears over time.

Inspect regularly for tension and wear. Refer to
Figure 33 for proper belt tension. Belt deflec­tion should be approximately
pressure. Replacement V-belts can be found in
the back of this manual in the part breakdowns.
Check pulleys to ensure that they are properly
aligned when installing V-belts.

To replace the V-belts, refer to Speed Changes
on Page 21 to loosen the belts. Remove them
from the pulleys, then install new V-belts.

Tensioning Return

Spring

5. Rotate cover counterclockwise to increase

tension, then push cover back in to engage
roll pin with one of the notches, as shown in
Figure 35.

The spring tension for automatic quill recoil has
been pre-set at the factory. It should not need
adjustment under most normal circumstances. If
it does need adjustment, the spring housing is
located on the left side of the headstock.

If the return spring should
come loose from the spring
cap and rapidly unwind,
laceration or impact inju­ries could occur. Always
wear heavy leather gloves
and safety glasses when
adjusting the return spring
tension.

To adjust spring tension:

1. DISCONNECT MACHINE FROM POWER!

2. PUT ON SAFETY GLASSES!

3. Loosen thumb knob shown in Figure 34

2–3 turns (DO NOT completely remove
thumb knob).

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-

nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical com­ponents!

MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpre­dictable results, including serious injury or fire.
This includes the installation of unapproved after­market parts.

WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires dis­connected or connected during any wiring task to
ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious per­sonal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.

MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.

CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
