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 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.

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 Drill Presses

or shav-

The primary risks of operating a Drill Press are as follows: You can be killed or seriously injured
if clothing, jewelry, or long hair gets entangled with rotating spindle or cutting tool/bit. You
can be severely cut or get your fingers amputated from contact with rotating cutting tool/bit.
You can be blinded or struck with great force by broken cutting tools, metal chips, unsecured
workpieces, chuck keys, or other adjustment tools thrown from rotating spindle. 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.

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.

REMOVE CHUCK KEY OR TOOLS BEFORE
STARTUP. 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.

PROPERLY SECURE CUTTING TOOL/BIT.
Firmly secure cutting tool or drill bit so it does not
fly out of spindle during operation or startup.

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

ALLOW SPINDLE TO STOP. To minimize risk of
entanglement, always allow spindle to stop on its
own. DO NOT stop spindle using your hand or any
other object.

INSPECT CUTTING TOOL/BIT BEFORE USE.
Inspect cutting tools for sharpness, chips, or
cracks before each use. Replace dull, chipped,
or cracked cutting tools immediately. Damaged
bits may break apart during operation. Dull bits
increase cutting resistance and are more likely to
grab and spin/throw workpiece.

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

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 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.

SECURE WORKPIECE TO TABLE. An unsecure
workpiece may unexpectedly shift, spin out of con­trol, or be thrown if cutting tool/bit ”grabs” during
operation. NEVER hold workpiece only by hand
during operation. Clamp workpiece to table or in a
vise mounted to table to properly secure it.

Model G0779 (Mfd. Since 09/14)

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.

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.

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

Model G0779 (Mfd. Since 09/14)

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.

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:

Grounding Requirements

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.

This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

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.

See below for required space allocation.

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 lift and place the machine:

1. Move shipping crate next to intended location

of drill press, then remove top portion of crate
from shipping pallet.

2. To help balance machine when moving,

move table as close to base as possible, and
raise headstock to its highest position.

Using Spindle

Downfeed Controls

This machine has coarse downfeed levers and a
fine downfeed handwheel.

Setting Depth Stop

The depth stop limits the drilling depth or down­ward movement of the cutting tool. Maximum
depth is 5". This is useful when performing the
same operation multiple times.

To operate the downfeed levers, simply pull for­ward and down on the lever nearest you. The
spindle will go down as far as it can until you stop
pulling or until it hits the depth stop, then it will
automatically return to the top when you release
pressure on the handle.

Note: Do not let go of the handle until the spindle
returns to the top position or the spindle will slam
upward into the quill.

Use the fine downfeed handwheel to control
the spindle travel up or down in slow, small
amounts. If necessary, you can lock the quill/
spindle in a lower position with the quill lock lever
(see Figure 20).

To operate fine downfeed handwheel:

1. Tighten downfeed selector knob, shown

in Figure 20. This transfers control from
downfeed levers to fine downfeed handwheel.

To set depth stop:

1. DISCONNECT MACHINE FROM POWER!

2. Install tooling (refer to Page 23), then make

sure spindle is drawn all the way up into
headstock.

3. Loosen hex nuts that lock headstock, and
lower headstock (see Raising/Lowering
Headstock on Page 21) until tooling is
approximately
retighten hex nuts.

4. Rotate depth stop adjustment knob until top
of depth stop pointer is level with desired
depth as listed on scale (see Figure 21).

Note: The depth stop scale functions as

a general guide only. It is not intended for
low-tolerance, precision results. To calibrate
the depth stop see Calibrating Depth Stop
on Page 36.

Spindle Speed

Using the correct spindle speed is important for
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 spindle
speed levers to produce the required spindle
speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed
to use for any given operation, but the two most
important are the recommended cutting speed
for the workpiece material and the diameter of
the cutting tool, as noted in the formula shown in
Figure 22.

*Recommended

Cutting Speed (FPM) x 12

Tool Dia. (in inches) x 3.14

*Double if using carbide cutting tool

Spindle

Speed
(RPM)

Setting Spindle Speed

Use the chart below or the one on the headstock
when setting the spindle speed.

Spindle Speed Range Lever Speed Lever

90 RPM L 1

210 RPM L 2

345 RPM L 3

670 RPM H 1

118 0 R PM H 2

1970 RPM H 3

Change spindle speed ONLY when the
spindle is completely stopped. Otherwise,
machine damage could occur.

With the spindle completely stopped, position the
spindle speed selectors (see Figure 23) to set the
spindle speed.

Note: If necessary, rotate the spindle by hand to
mesh the gears when changing speeds.

Figure 22. Spindle speed formula for drills.

Cutting speed, typically defined in feet per minute
(FPM), is the speed at which the edge of a tool
moves across the material surface.

A recommended cutting speed is an ideal speed
for cutting a type of material in order to produce
the desired finish and optimize tool life.

The books Machinery’s Handbook or Machine
Shop Practice, and some internet sites, pro­vide excellent recommendations for which cutting
speeds to use when calculating the spindle speed.
These sources also provide a wealth of additional
information about the variables that affect cutting
speed and they are a good educational resource.

Also, there are a large number of easy-to-use
spindle speed calculators that can be found on
the internet. These sources will help you take into
account the applicable variables in order to deter­mine the best spindle speed for the operation.

Calculating Spindle Speed for Drilling

Using the Drilling Speed Chart

The chart shown in Figure 24 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.

Larger bits turning at slower speeds tend
to grab the workpiece aggressively. This
can result in the operator's hand being
pulled into the bit or the workpiece being
thrown with great force. Always clamp the
workpiece to the table to prevent injuries.

T26685—ISO 32 Moly-D Machine Oil, 1 gal.

Moly-D oils are some of the best we've found for
maintaining the critical components of machinery
because they tend to resist run-off and maintain
their lubricity under a variety of conditions—as
well as reduce chatter or slip. Buy in bulk and
save with 5-gallon quantities.

Cleaning &

To reduce risk of shock or

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.

Daily Check

• Check/repair loose mounting bolts or fasten-

ers.

• Check/repair worn or damaged wires.

• Check/repair damaged tooling.

• Clean debris and built-up grime off of machine.

• Check/resolve any other unsafe condition.

Every 8 Hours of Operation:

• Check/add headstock oil (Page 32).

• Lubricate column, racks, and quill (Page 33).

Every 90 Hours of Operation:

• Lubricate quill rack and pinion (Page 33).

Every 180 Days of Operation:

• Change headstock oil (Page 32).

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 drill press and treat with a
non- staining lubricant after cleaning.

Keep unpainted cast iron surfaces rust-free with
regular applications of ISO 68 way oil (see Page

28 for offerings from Grizzly).

Lubrication

An essential part of lubrication is cleaning the
components before lubricating them.

This step is critical because grime and chips build
up on lubricated components, which makes them
hard to move. Simply adding more lubricant will
not result in smooth moving parts.

Model G0779 (Mfd. Since 09/14)

Clean all exterior components in this section with
mineral spirits, shop rags, and brushes before
lubricating.

DISCONNECT MACHINE FROM POWER
BEFORE PERFORMING LUBRICATION!

NOTICE

Follow reasonable lubrication practices as
outlined in this manual. Failure to do so
could lead to premature failure of your
machine and will void the warranty.

-31-

For the quill, table, and column, an occasional
application of light machine oil is all that is neces­sary. Before applying lubricant, clean off any dust
or metal chips.

4. Place drain pan on table under headstock.

5. Remove cover plate from bottom of head-

stock (see Figure 40).

Your goal is to achieve adequate lubrication. Too
much lubrication will attract dirt and dust. Various
parts of your machine could lose their freedom of
movement as a result.

tension, then push cover back in to engage
roll pin with one of the notches, as shown in
Figure 45, then retighten thumb knob.

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!

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.
