Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter

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.
Alerts the user to useful information about proper operation of the
NOTICE
machine to avoid machine damage.
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-
Model T33962/T33963 (Mfd. Since 10/23)
-11-
Page 14
may damage the wires inside. Do not handle
WEARING PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, 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 rec-
ommended 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
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 (570) 546-9663.

drilling control or bit breakage, only drill into a flat
surface that is approximately perpendicular to
tool/bit, tighten all table and headstock locks
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.
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
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 machinery there is potential danger
when operating this machine. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.
Model T33962/T33963 (Mfd. Since 10/23)
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.
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:

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
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).
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:

Cleanup
parts of the
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 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.
Before cleaning, gather the following:

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
The physical environment where the machine is
operated is important for safe operation and longevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemicals, 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,
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
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.

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.
Bench Mounting
The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.
The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.

Spindle Speed
*
Cutting speed, typically defined in feet per minute
(FPM), is the speed at which the edge of a tool
moves across the material surface.
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, 2) configure the machine for
the correct speed range, and 3) adjust the spindle
speed dial to produce the required spindle speed.
Refer to Determining Drilling Spindle Speed
and Determining Tapping Spindle Speed for
guidance on determining the best spindle speed
for drilling and tapping operations. Additionally,
the books Machinery’s Handbook or Machine
Shop Practice, and some internet sites, provide excellent recommendations for which cutting
speeds or feed speeds to use when calculating
the spindle speed. These sources also provide
a wealth of additional information about the variables that affect this 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.
When you are have determined the correct spindle speed for your operation, refer to Changing
Spindle Speed Range on Page 38 to configure your machine for the correct speed range.
Determining Drilling Spindle Speed
Many variables affect the optimum spindle speed
to use for any given drilling 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 51.
*Recommended
Cutting Speed (FPM) x 12
Tool Dia. (in inches) x 3.14
Double if using carbide cutting tool
Figure 51. Drilling spindle speed formula.
Spindle
=
Speed
(RPM)
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. Refer to
the Spindle Speed Chart on Page 37 for additional information.
Determining Tapping Spindle Speed
There are a number of variables to consider when
determining the spindle speed for a power tapping
operation: the tap diameter, the flute style of the
tap; the number of chamfered threads on the tap;
the workpiece material; the depth of the intended
tap; and the coarseness of the thread pitch.
Turning a tap at too high of an RPM increases
the risk of it binding or breaking, and taps are
hardened and therefore difficult to remove if they
break off inside your workpiece. While some tapping setups will allow you to turn the spindle at a
higher RPM, we recommend setting the Model
T33962/T33963 as slow as possible (less than 80
RPM). This will allow you to observe the tap as it
threads to ensure the tap does not come loose in
the chuck and to back out the tap as needed to
clear chips or otherwise resolve any issues.
Most tapping operations require a lubricant or tapping fluid to aid in tapping threads. A list of suggested tapping lubricants based on material type
has been provided below.

Using Drilling Spindle Speed Chart
The chart shown in Figure 52 is intended as a
generic 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.

Changing Spindle
Speed Range
This machine has two speed ranges: a low speed
range that operates between 0–600 RPM, and a
high speed range that operates between 0–2100
RPM. The speed range is determined by how
the V-belt is installed on the motor and spindle
pulleys (see Figure 53).
Motor
Pulley
V-Belt
Spindle
Pulley
The V-belt transfers power from the motor to the
spindle. If the V-belt is worn or damaged in any
way, the drill press will not operate optimally, and
unnecessary wear on the moving parts will occur.
Whenever you are changing the spindle speed
range, inspect the V-belt for damage or wear and
replace it if necessary.
Use care when handling V-belt as it could
pinch your fingers. It may also be hot after
extended use, so wait to touch V-belt if
machine has been in use.

The spindle direction can also be reversed when
the REVERSE TAPPING button is pressed after
the tap is engaged and prior to the drilling depth
being reached. This button will allow you to clear
waste chips out of the hole during the tapping
process or immediately back out a tap if you
notice the tap binding or slipping in the chuck.
Frequently removing waste chips will prevent galling and tap breakage.
The following steps describe a typical tapping
operation on this machine, but different taps and
operation requirements may vary. If you are unfamiliar with tapping on a drill press, we strongly
recommend that you read books, review industry
trade magazines, or get formal training before
attempting tapping projects.
Use correct diameter of drill bit to drill
pilot hole prior to beginning any tapping
operation. Attempting to cut threads into an
incorrectly sized hole can cause tap to snap
and eject splinters.
DO NOT use hand taps on this machine.
Hand taps are not designed to eject chips
during operation so they require a much
slower spindle RPM and feeding technique.
-40-
In order to prevent injury to operator and
bystanders, DO NOT clear chips from
workpiece surface while machine is ON or
use hands or compressed air to clear chips.

SECTION 6: MAINTENANCE
To reduce risk of shock or
accidental startup, always
disconnect machine from
Cleaning &
Protecting
power before adjustments,
maintenance, or service.
Schedule
For optimum performance from this machine, this
maintenance schedule must be strictly followed.
Ongoing
To minimize your risk of injury and maintain proper
machine operation, shut down the machine immediately if you ever observe any of the items below,
and fix the problem before continuing operations:
• Loose mounting bolts.
• Damaged tooling.
Damaged or missing chip guard.
•
Worn or damaged wires.
•
Worn or damaged buttons, switches, or dials.
•
Debris and built up grime.
•
Damaged V-belt.
•
Any other unsafe condition.
•
Cleaning the machine is relatively easy. Sawdust,
wood chips, and metal chips that have been
soaked with water-based cutting fluid or lubricant
left on the machine will invite oxidation and a
gummy residue build-up around the moving parts.
Vacuum excess wood chips and sawdust, and
wipe off the remaining dust with a dry cloth. If any
resin has built up, use a resin dissolving cleaner
to remove it. Use a brush and shop vacuum to
remove metal chips and debris from the work surface. Never blow off debris with compressed air,
as this will force chips deep into the mechanisms
and may cause injury to yourself or bystanders.
Protect the unpainted cast iron table and base by
wiping them clean after every use—this ensures
moisture from wood dust does not remain on bare
metal surfaces. Keep the table and base rust-free
with regular applications of metal protectant products like SLIPIT® (see Figure 61 on Page 42).
Lubrication
Weekly Maintenance
• Lubricate quill and column surfaces
(Page 44).
Monthly Check
• Check V-belt for damage or wear (Page 38).
• Lubricate quill rack and pinion (Page 44).
• Model T33963 Only: Lubricate column
rack (Page 44).
• Clean/vacuum dust buildup off of motor.
Model T33962/T33963 (Mfd. Since 10/23)
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.
Lubricate components with recommended
products like those shown in Accessories on
Page 42.

Aligning
Motor Pulley
Pulley alignment is an important factor in power
transmission and belt life. The pulleys should
be parallel to each other and in the same plane
(coplanar) for optimum performance.
Use a straightedge to check the pulley alignment,
as shown in Figure 64. The motor pulley can be
adjusted up and down on its shaft.

SECTION 8: WIRING
Note: Please gather the serial
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.
EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.
