connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!
DISCONNECT POWER FIRST. Always discon-
nect machine from power supply BEFORE making
adjustments, changingtooling, orservicingmachine.
This prevents an injury risk from unintended startup
or contact with live electrical components.
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.
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.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin-
ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

WEARING PROPER APPAREL. Do not wear FORCING MACHINERY. Do not force machine.
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.
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.
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 mate-
rial. Always wear a NIOSH-approved respirator to

Additional Safety for Drill Presses
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 INSPECT CUTTING TOOL/BIT BEFORE USE.

SECTION 2: POWER SUPPLY
Availability
Circuit Information
Before installing the machine, consider the avail-
ability 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.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply 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.)
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
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, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
Full-Load Current Rating
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.
Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Full-Load Current Rating at 220V ....8.6 Amps
Nominal Voltage .........208V, 220V, 230V, 240V
Cycle..........................................................60 Hz
Phase........................................... Single-Phase
Power Supply Circuit ......................... 15 Amps
Plug/Receptacle ............................. NEMA 6-15
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 over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit 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.
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
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!
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 nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
GROUNDED
6-15 RECEPTACLE
Check with a qualified electrician or service per-
sonnel 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, discon-
nect it from power, and immediately replace it with
a new one.

Extension Cords
Figure 4. Typical 6-15 plug and receptacle.
We do not recommend using an extension cord
with this machine. If you must use an extension
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).
No adapter should be used with plug. If
plug does not fit available receptacle, or if
machine must be reconnected for use on a
different type of circuit, reconnection must
be performed by an electrician or qualified
service personnel, and it must comply with
all local codes and ordinances.
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:
Minimum Gauge Size...........................14 AWG
Maximum Length (Shorter is Better).......50 ft.

Cleanup
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. Avoid
using these products
to clean machinery.
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.
Many cleaning solvents
are toxic if inhaled. Only
work in a well-ventilated
area.
There are many ways to remove this rust preven-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac-
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.
Before cleaning, gather the following:
•
•
•
•
Disposable rags
Cleaner/degreaser (WD•40 works well)
Safety glasses & disposable gloves
Plastic paint scraper (optional)
T23692—Orange Power Degreaser
A great product for removing the waxy shipping
grease from your machine during clean up.
Basic steps for removing rust preventative:
1. Put on safety glasses.
2. Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3. Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
Figure 6. T23692 Orange Power Degreaser.
4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.

Site Considerations
Weight Load
Physical Environment
Refer to the Machine Data Sheet for the weight
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 work-
piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
The physical environment where the machine is
operated is important for safe operation and lon-
gevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemi-
cals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20%–95% (non-condensing); or
the environment is subject to vibration, shocks,
or bumps.
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 main-
tenance and service described in this manual.
See below for required space allocation.
Electrical Installation
Place this machine near an existing power source.
Make sure all power cords are protected from
traffic, material handling, moisture, chemicals, or
other hazards. Make sure to leave enough space
around machine to disconnect power supply or
apply a lockout/tagout device, if required.
Lighting
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.

Lifting & Placing
Anchoring to Floor
Number of Mounting Holes ............................ 4
Diameter of Mounting Hardware................. 1⁄2
"
HEAVY LIFT!
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.
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,
get help from other people
and use a forklift (or other
lifting equipment) rated for
weight of this machine.
If the machine will be installed in a commercial or
workplace setting, or if it is permanently connect-
ed (hardwired) to the power supply, local codes
may require that it be anchored to the floor.
To lift and place the machine:
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 rec-
ommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.
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.
Anchoring to Concrete Floors
Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a con-
crete 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.
3. Place lifting sling around headstock (see
Figure 8), and attach it securely to forklift (or
other power lifting equipment).
Note: Make sure you tighten all locks that
restrict moving parts to avoid sudden shifts
which could unbalance machine.

Arbor/Chuck
Assembly
Initial Lubrication
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.
GEARBOX MUST
BE FILLED WITH OIL!
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.
OIL MAY NOT BE
SHIPPED WITH MACHINE!
Refer to Lubrication Section
for Correct Oil Type.
Important: DO NOT install the drill chuck and
arbor assembly into the spindle until AFTER the
test run.
To join drill chuck and arbor:
To prevent spillage, this machine was shipped
from the factory without any oil in it. The head-
stock oil reservoir must be properly filled with oil
before the drill press can be operated for the first
time. Refer to the Lubrication section, beginning
on Page 31, for details on how to check and add
oil.
1. Use acetone or lacquer thinner to clean drill
chuck and arbor mating surfaces, especially
the bore.
2. Retract chuck jaws completely into chuck.
3. Insert small end of arbor into chuck.
4. Hold assembly by the arbor and tap chuck
onto a block of wood with medium force, as
illustrated below.
Damage caused by running the drill press
without oil in the reservoir will not be cov-
ered under warranty.
Figure 10. Arbor/chuck assembly.
5. Attempt to separate drill chuck and arbor by
hand—if they separate, repeat Steps 3–4.

Test Run
Spindle Break-In
Once assembly is complete, test run the machine
to ensure it is properly connected to power and
safety components are functioning properly.
The spindle break-in procedure distributes lubri-
cation throughout the bearings to reduce the risk
of early bearing failure if there are any "dry" spots
or areas where lubrication has settled in the bear-
ings. You must complete this procedure before
placing operational loads on the spindle for the
first time when the machine is new or if it has
been sitting idle for longer than 6 months.
If you find an unusual problem during the test run,
immediately stop the machine, disconnect it from
power, and fix the problem BEFORE operating the
machine again. The Troubleshooting table in the
SERVICE section of this manual can help.
Always start the spindle break-in at the lowest
speed to minimize wear if there are dry spots.
Allow the spindle to run long enough to warm up
and distribute the bearing grease, then incremen-
tally increase spindle speeds, allowing the spindle
to run the same amount of time at each speed, until
reaching the maximum spindle speed. Following
the break-in procedure in this progressive man-
ner helps minimize any potential wear that could
occur until lubrication is fully distributed.
Serious injury or death can result from
using this machine BEFORE understanding
its controls and related safety information.
DO NOT operate, or allow others to operate,
machine until the information is understood.
DO NOT start machine until all preceding
setup instructions have been performed.
Operating an improperly set up machine
may result in malfunction or unexpect-
ed results that can lead to serious injury,
death, or machine/property damage.
Do not leave drill press unattended dur-
ing Spindle Break-In procedure. If your
attention is needed elsewhere during this
procedure, turn machine OFF and restart
procedure later from the beginning.
To perform spindle break-in procedure:
Make sure headstock has proper amount of
oil before performing Test Run and Spindle
Break-In. Otherwise, headstock compo-
nents may be damaged and void warranty.
Refer to Page 32 for detailed instructions.
1. Make sure spindle is completely stopped,
then set spindle speed to 90 RPM (refer to
Page 25 for detailed instructions).
2. Run machine for a minimum of 5 minutes in
each spindle direction.
To test run machine:
3. Repeat Step 2 for each of the spindle speeds.
1. Clear all setup tools away from machine.
2. Connect machine to power supply.
3. Set spindle speed to 90 RPM (see Page 25).
4. Change headstock oil (refer to Page 31 for
detailed instructions).
Congratulations! The test run and spindle break-in
are now complete!
4. Rotate spindle switch to RIGHT to turn
machine ON. Verify motor operation, then
turn machine OFF. The motor should run
smoothly and without unusual problems or
noises. Repeat with switch set to LEFT.

Using Spindle
Setting Depth Stop
Downfeed Controls
The depth stop limits the drilling depth or down-
ward movement of the cutting tool. Maximum
depth is 5". This is useful when performing the
same operation multiple times.
This machine has coarse downfeed levers and a
fine downfeed handwheel.
To operate the downfeed levers, simply pull for-
ward 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.
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.
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.
3. Loosen hex nuts that lock headstock, and
lower headstock (see Raising/Lowering
Headstock on Page 21) until tooling is

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.
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.

Calculating Spindle Speed for Drilling
Using the Drilling Speed Chart
Lubrication Suggestions
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.
Wood ...........................................................None
Plastics ............................................Soapy Water
Brass ...............................Water-Based Lubricant
Aluminum..................... Paraffin-Based Lubricant
Mild Steel............................. Oil-Based Lubricant
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.
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.
Often, when drilling materials other than wood,
some type of lubrication is necessary.

SECTION 6: MAINTENANCE
Cleaning &
Protecting
To reduce risk of shock or
accidental startup, always
disconnect machine from
power before adjustments,
maintenance, or service.
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.
Schedule
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Remove any rust build-up from unpainted cast
iron surfaces of your drill press and treat with a
non- staining lubricant after cleaning.
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.
Keep unpainted cast iron surfaces rust-free with
regular applications of ISO 68 way oil (see Page
28 for offerings from Grizzly).
•
•
•
•
Lubrication
Every 8 Hours of Operation:
•
Check/add headstock oil (Page 32).
•
Lubricate column, racks, and quill (Page 33).
An essential part of lubrication is cleaning the
components before lubricating them.
Every 90 Hours of Operation:
Lubricate quill rack and pinion (Page 33).
•
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.
Every 180 Days of Operation:
Change headstock oil (Page 32).
•
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.

For the quill, table, and column, an occasional
application of light machine oil is all that is neces-
sary. 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.
6. Remove drain plug (see Figure 40) from
underneath headstock and allow oil to drain
into pan.

the column rack. Move each component through
the entire path of travel several times to distribute
the lubricant.
Note: Take care not to remove the quill rack
grease without re-applying it.
