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.

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

Serious injury or death can occur from getting clothing, jewelry, or long hair entangled in
rotating spindle or bit/cutting tool. Contact with rotating bit/cutting tool can result in severe cuts
or amputation of fingers. Flying metal chips can cause blindness or eye injuries. Broken bits/
cutting tools, unsecured workpieces, chuck keys, or other adjustment tools thrown from rotating
spindle can strike nearby operator or bystanders with deadly force. To reduce the risk of these
hazards, operator and bystanders MUST completely heed hazards and warnings below.

EYE/FACE/HAND PROTECTION. Flying chips

created by drilling can cause eye injuries or blind­ness. Always wear a face shield in addition to
safety glasses. Always keep hands and fingers
away from drill bit/cutting tool. Avoid awkward
hand positions, where a sudden slip could cause
hand to move into bit/cutting tool.

AVOIDING ENTANGLEMENT. DO NOT wear
loose clothing, gloves, or jewelry. Tie back long
hair. Keep all guards in place and secure. Always
allow spindle to stop on its own. DO NOT stop
spindle using your hand or any other object.

REMOVING ADJUSTMENT TOOLS. Chuck key,
wrenches, and other tools left on machine can
become deadly projectiles when spindle is started.
Remove all loose items or tools used on spindle
immediately after use.

CORRECT SPINDLE SPEED. Using wrong spin­dle speed can cause bits/cutting tools to break
and strike operator or bystanders. Follow recom­mended speeds and feeds for each size/type of
bit/cutting tool and workpiece material.

SECURING BIT/CUTTING TOOL. Firmly secure
bit/cutting tool in chuck so it cannot fly out of
spindle during operation or startup.

DRILLING PREPARATION. To avoid loss of drilling
control or bit breakage, only drill into a flat surface
that is approximately perpendicular to bit. Clear
table of all objects before starting spindle. Never
start spindle with bit pressed against workpiece.

SECURING TABLE AND HEADSTOCK. To avoid
loss of control leading to accidental contact with
tool/bit, tighten all table and headstock locks
before operating drill press.

WORKPIECE CONTROL. An unsecured
workpiece may unexpectedly shift, spin out of con­trol, or be thrown if bit/cutting tool "grabs" during
operation. Clamp workpiece to table or in table­mounted vise, or brace against column to prevent
rotation. NEVER hold workpiece by hand during
operation. NEVER start machine with bit/cutting
tool touching workpiece; allow spindle to gain full
speed before drilling.

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

Like all machines there is danger associated
with this machine. Accidents are frequently
caused by lack of familiarity or failure to pay
attention. Use this machine with respect
and caution to lessen the possibility of
operator injury. If normal safety precautions
are overlooked or ignored, serious personal
injury may occur.

Model G0793 (Mfd. Since 02/15)

No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per­sonal injury, damage to equipment, or poor
work results.

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.)

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

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.

Physical Environment

Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.

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.

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 drill press:

1. Place shipping crate near final machine

mounting location.

2. Remove top portion of crate from shipping

pallet, secure ends of a properly rated lifting
sling around each side of bar placed through
lifting holes, and attach it securely to your
power lifting equipment (see Figure 6).

Arbor/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

Initial Lubrication

GEARBOXES MUST

BE FILLED WITH OIL!

OIL MAY NOT BE

SHIPPED WITH MACHINE!

Refer to Lubrication Section

for Correct Oil Type.

To prevent spillage, this machine was shipped
from the factory without any oil or coolant in it.
The headstock and gearbox oil reservoirs must
be properly filled with oil before the drill press
can be operated for the first time. In addition, the
coolant pump reservoir must be filled properly
before operation. Refer to the Lubrication sec­tion, beginning on Page 33, for details on how to
check and add oil or coolant.

Damage caused by running drill press with­out oil in reservoirs is not covered under
warranty.

Figure 8. Installing arbor into chuck.

If pump is running, ball valve is open, and
no coolant is flowing from coolant nozzle,
this is an indication of inadequate coolant
levels in reservoir. Immediately turn pump
OFF! Running pump without adequate cool­ant can lead to pump damage, which will not
be covered under warranty.
