-7-
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 mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing 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 modifica-
tions—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.

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 dur-
ing 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 acces-
sories will increase the risk of serious injury.

Additional Safety for Lathe Tool Post
Grinders
Serious injury or death can occur from getting clothing, jewelry, or long hair entangled in
moving parts or pinch points. Flying debris created by broken grinding wheels or grinding
operations can blind or strike nearby operators with deadly force. Rotating grinding wheel will
quickly remove skin upon contact. To reduce the risk of operator (or bystander) injury or death,
anyone operating machine MUST completely heed the warnings below.
AVOID HAND & WHEEL CONTACT. Position
your hands at a safe distance from wheel when
grinding. Avoid wearing gloves as they may get
caught in spinning wheel or pulleys, resulting in
serious entanglement injuries.
USE CORRECT WHEEL FLANGES. Only use
flanges included with grinder when mounting
external wheel. Other flanges may not properly
secure wheel. DO NOT use warped or damaged
flanges, and always use paper discs (blotters)
between wheel and flanges to reduce risk of
flanges cracking external wheel when tightened.
CHECK FOR VIBRATING WHEEL. Never
perform grinding operations on a wheel that is
vibrating. Immediately replace wheel or shaft
bearings.
WEAR EYE, FACE, & LUNG PROTECTION.
Grinding ejects small particles at a high rate of
speed. These particles can cause eye injuries or
blindness, skin injuries, or respiratory damage.
ALWAYS wear approved clothing, safety goggles,
face shield, and a respirator when grinding.
USE INCLUDED PULLEY & WHEEL
HARDWARE. Using pulleys or wheel mounting
hardware other than those supplied with this
grinder could cause pulleys or wheels to come
loose during operation, causing impact injuries.
PROPERLY TIGHTEN SPINDLE NUT.
Only tighten wheel spindle nut enough to drive
wheel and prevent slippage. Overtightening can
crack wheel, which would cause it to fly apart dur-
ing operation.
PROPERLY SECURE GRINDER & ENSURE
SAFE WORK AREA. Unexpected movement of
grinder could cause grinding wheel to break or fly
apart during operation. Before use, verify grinder
is properly secured in place before operation and
nearby area is free of explosive or flammable
materials.
SAFELY START GRINDER. If a wheel is dam-
aged, it will usually fly apart shortly after start-
up. To protect yourself, always stand to side of
grinder when turning it ON and allow it to run for
at least one minute before standing in front of it.
PERFORM VISUAL INSPECTION. Verify that
grinding wheels are free of cracks, chips, or dents
in wheel surface before installing. DO NOT use
wheels that have been dropped or otherwise have
any of these problemsthey could break apart
during operation.
PERFORM RING TEST. Perform a “ring test”
on external grinding wheel before installation
to ensure it is safe to use. A wheel that does
NOT pass ring test may break or fly apart during
operation. DO NOT use it!
CHECK WHEEL SPEED RATING. Wheels
operated faster than their rated speed may
break apart during operation. Before
mounting a new wheel, be sure wheel
RPM rating is equal or higher than speed of
grinder. Never use unmarked wheels.
AVOID ENTANGLEMENT. Becoming entangled
in moving parts of grinder can cause pinching
and crushing injuries. To avoid these hazards, DO
NOT wear loose clothing, gloves, or jewelry, and
tie back long hair. Keep all guards in place and
secure.

SECTION 2: POWER SUPPLY
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
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.
Full-Load Current Rating at 220V .... 3.5 Amps
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.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
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.
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.)
Circuit Information
Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage ........................................220V
Cycle ..........................................................60 Hz
Phase ........................................... Single-Phase
Power Supply Circuit ......................... 15 Amps
Plug/Receptacle ......................................... 6-15
Availability
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.
-10-
Model T27400 (Mfd. Since 02/15)
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.
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
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:
Minimum Gauge Size ...........................16 AWG
Maximum Length (Shorter is Better).......50 ft.

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!
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.
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.

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 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.
Before cleaning, gather the following:
Disposable rags
Cleaner/degreaser (WD•40 works well)
Safety glasses & disposable gloves
Plastic paint scraper (optional)
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-

Lathe Requirements
The maximum tool post diameter the grinder can
accommodate is 1". If the diameter of your tool
post does not allow you to secure the grinder to
the compound slide without side-to-side move-
ment, make a bushing for the tool post that will
keep the grinder secured in place when the tool-
post nut is fully tightened down.
Note: The tool post grinder mounting hole clear-
ance may not allow for the lathe's tool post lever to
rotate fully. A new tool post nut and washer combi-
nation may be required to secure the grinder.

External Wheel Clearance
The distance between the tool post centerline and
the outside grinding surface of a new 6" external
wheel is approximately 7" when the grinder is
installed, as illustrated in Figure 3. Ensure that
your compound slide can safely accommodate
this distance from the workpiece prior to powering
machine. Smaller lathes may require additional
compound slide adjustment, or require small
diameter workpieces.
Centerline Alignment
When using an external grinding wheel, the cen-
terline of the grinder spindle should be approxi-
mately the same height as the lathe centerline for
proper contact with the spinning workpiece.
The grinder spindle centerline is adjustable from
1
5
8"–2
1
8" above the top of the lathe's compound
slide. Measure the height to the lathe centerline
from the top of the compound slide (distance A
illustrated in Figure 3) to ensure it is within this
range. Most lathe centerlines will be within the
adjustable range. If not, re-adjust the compound
slide and place the external wheel as close to
workpiece centerline as possible.
Once the grinder centerline is adjusted, tighten
the height tension bolt and nut to secure the dove-
tail in place.
IMPORTANT: You must adjust and retighten the
belt any time the centerline adjustment is changed
(see Tensioning/Changing Belts on Page 20).
The Model T27400 is designed to fit on metal
lathes with a 12"–22" swing and a 1" diameter
tool post.
IMPORTANT: Although the Model T27400 will fit
on lathes meeting the size requirements specified
above, this does not imply or guarantee that it will
allow enough clearance to work with the full swing
of the installed lathe. Once installed, the maximum
possible workpiece swing allowed is determined
by the distance from the tool post centerline (with
cross slide positioned fully backward) to the lathe
spindle centerline, minus the required installation
space for the tool post grinder (approximately 7").

Mounting on Tool
Post
The T27400 mounts directly to the tool post on
the compound slide of the lathe. On small lathes,
ensure proper workpiece clearance by mounting
the grinder before attaching a workpiece to the
lathe chuck.
To mount grinder on the lathe tool post:
1. DISCONNECT LATHE FROM POWER!
2. Remove tool post nut (or lever) from lathe,
and remove tool holder or any other tool
hardware from tool post stud.
3. Rotate compound slide parallel to lathe
bedway, then tighten rotation locks on slide.
4. Place grinder over tool post on compound
slide, and position it so grinding wheel faces
lathe centerline, as shown in Figure 4.
Figure 4. Grinder correctly mounted to lathe
compound slide.
Unexpected movement of grinder on tool
post could cause grinding wheel to break
apart and strike operator or bystanders
with great force. Always make sure grinder
is firmly secured to tool post so there is no
side-to-side or up-and-down movement.
5. Use tool post nut to firmly secure grinder in
place, as shown in Figure 5.
Note: Tool post mounting hole of grinder
will accept tool post up to 1" in diameter.
However, if diameter or height of your tool
post allows for side-to-side or up-and-down
movement of grinder when nut is fully tight-
ened, you will need to fabricate a custom
washer for tool post.

custom washer.

Adjusting Grinder
Centerline Height
The centerline of the external grinding wheel must
closely align with the centerline of the workpiece
to avoid damage to the wheel guard or the
workpiece (see Figure 3 on Page 13). The tool
post grinder centerline height can be adjusted
from 1
5
8" to 2
1
8" above the top of the lathe's com-
pound slide. Once the grinder centerline height is
properly adjusted, the height tension bolt and nut
must be tightened to secure the centerline height
in place.
Tools Needed Qty
Wrench 18mm ................................................... 1
Hex Wrench 8mm .............................................. 1
To adjust tool post grinder centerline height:
1. DISCONNECT LATHE AND GRINDER
FROM POWER!
2. Loosen hex bolt on left side of spindle hous-
ing (see Figure 6).
3. Rotate elevation bolt (see Figure 6) as nec-
essary to align grinder spindle centerline with
lathe spindle centerline. Rotate bolt counter-
clockwise to raise grinder spindle or clock-
wise to lower it.
Note: Numerical increments on elevation
wheel are for your reference only and do not
indicate actual height of spindle.
4. When you are satisfied with adjustment, re-
tighten hex bolt to secure setting.

Lathe Rotation
To produce the best results, use a test piece
similar to workpiece to verify proper lathe spindle
speed settings. Proper lathe and grinder rotation
orientation will ensure a cleaner finished product.
Both the lathe and the external grinding wheel
should rotate clockwise, as illustrated in Figure 7.
When using the internal wheel, set lathe rotation
to counterclockwise.

Figure 7. Correct lathe rotations.
When grinding, the safety of operator and bystand-
ers depends primarily on the condition of the
wheel. A wheel in poor condition could break
apart during rotation and injure the operator or
nearby bystanders.
Here are some tips to help you avoid breaking
the wheel:
Always transport, store and handle wheels
with care. Wheels may be damaged if they
are dropped or if heavy objects are stacked
on them.
Select the right grinding wheel for the job.
Attempting to use an external wheel for an
internal grinding operation, or vice versa, will
not work and will increase the risk of personal
injury and property damage.
Only use wheels that are rated for the RPM
of the tool grinder.
Mount the wheel properly (see Installing/
Removing Grinding Wheel on Page 24).
Do not abuse the wheel by jamming it into
the workpiece with excessive force, or by
allowing the workpiece to become overly hot
during operation.
Do not store wheels in damp or wet locations.
Do not overtighten the nut when mounting the
wheel.
Do not leave the wheel mounted when
machine is not in use.
