Understanding Risks of Machinery
Operating all machinery and machining equipment can be dangerous or
relatively safe depending on how it is installed and maintained, and the
operator's experience, common sense, risk awareness, working conditions, and
use of personal protective equipment (safety glasses, respirators, etc.).
The owner of this machinery or equipment is ultimately responsible for its safe
use. This responsibility includes proper installation in a safe environment,
personnel training and usage authorization, regular inspection and
maintenance, manual availability and comprehension, application of safety
devices, integrity of cutting tools or accessories, and the usage of approved
personal protective equipment by all operators and bystanders.
The manufacturer of this machinery or equipment will not be held
liable for injury or property damage from negligence, improper training,
machinemodifications, or misuse. Failure to read, understand, and follow the
manual and safety labels may result in serious personal injury, including
amputation, broken bones, electrocution, or death.
The signals used in this manual to identify hazard levels are defined
as follows:
Death or catastrophic harm WILL occur.
Death or catastrophic harm COULD occur.
Moderate injury or fire MAY occur.
Machinery or property damage may occur.
Basic Machine Safety
Entanglement: Loose clothing, gloves,
neckties, jewelry or long hair may
get caught in moving parts, causing
entanglement, amputation, crushing,
or strangulation. Reduce this risk
by removing/securing these items so

a wet environment may result in
electrocution; operating near highly
flammable materials may result in
a fire or explosion. Only operate this
item in a dry location that is free
from flammable materials.
Electrical Connection: With
electically powered equipment,
improper connections to the power
source may result in electrocution or
fire. Always adhere to all electrical
requirements and applicable codes
when connecting to the power
source. Have all work inspected by a

of electrocution or fire.
Unattended Operation: Electrically
powered equipment that is left
unattended while running cannot
be controlled and is dangerous to
bystanders. Always turn the power
OFF before walking away.
Guards/Covers: Accidental contact
with moving parts during operation
may cause severe entanglement,
impact, cutting, or crushing injuries.
Reduce this risk by keeping any
included guards/covers/doors
Mental Alertness: Operating this
item with reduced mental alertness
increases the risk of accidental
injury. Do not let a temporary
influence or distraction lead to a
permanent disability! Never operate
when under the influence of drugs/
alcohol, when tired, or otherwise
distracted.
installed, fully functional, and
positioned for maximum protection.
Difficult Operations: Attempting
difficult operations with which you
are unfamiliar increases the risk of
injury. If you experience difficulties
performing the intended operation,
STOP! Seek an alternative method
to accomplish the same task, ask a
qualified expert how the operation
should be performed, or contact our
Technical Support for assistance.
Health Hazards: Certain cutting
fluids and lubricants, or dust/
smoke created when cutting,
may contain chemicals known to
the State of California to cause
cancer, respiratory problems, birth
defects, or other reproductive
harm. Minimize exposure to these
chemicals by wearing approved
personal protective equipment and
operating in a well ventilated area.
Chuck Keys or Adjusting Tools: Tools
used to adjust spindles, chucks,
or any moving/rotating parts will
become dangerous projectiles if left
in place when the machine is started.
Reduce this risk by developing the
habit of always removing these tools
immediately after using them.
Work Area: Clutter and dark
shadows increase the risk of
accidental injury. Only operate this
item in a clean, non-glaring, and
well-lighted work area.

Basic steps for removing rust
preventative:
Cleaning & Protecting
The unpainted surfaces are coated
at the factory with a heavy-duty
rust preventative that prevents
corrosion during shipment and
storage.The benefit of this rust
preventative is that it works very
well. The downside is that it can
be time-consuming to thoroughly
remove.
1. Put on safety glasses and
disposable gloves.
2. Coat all surfaces that have
rust preventative with a liberal
amount of your cleaner or
degreaser and let them soak for
a few minutes.
3. Wipe off the surfaces. If your
cleaner or degreaser is effective,
the rust preventative will wipe
off easily.
Be patient and do a careful job when
cleaning and removing the rust
preventative. The time you spend
doing this will reward you with
smooth-sliding parts and a better
appreciation for the proper care of
the unpainted surfaces.
Note: To clean off thick coats of rust
preventative on flat surfaces,
such as beds or tables, use
a PLASTIC paint scraper to
scrape off the majority of the
coating before wiping it off with
your rag. (Do not use a metal
scraper or it may scratch the
surface.)
Although there are many ways
to successfully remove the rust
preventative, we have cleaned
thousands of machines and found
the following process to be the best
balance between efficiency and
minimized exposure to toxic fumes
or chemicals.
4. Repeat Steps 2–3 as necessary
until clean, then coat all
unpainted surfaces with a
quality metal protectant or light
oil to prevent rust.
Before cleaning, gather the
following:
•
•
Disposable rags
Cleaner/degreaser (certain
citrus-based degreasers work
extremely well and they have
non-toxic fumes)
Gasoline and petroleum
products have low flash points
and can explode or cause fire if
used for cleaning. Avoid using
these products to remove rust
preventative.
•
Safety glasses & disposable
gloves
Note: Automotive degreasers,
mineral spirits, or WD•40 can be
used to remove rust preventative.
Before using these products, though,
test them on an inconspicuous area
of a painted area to make sure they
will not damage it.
Many cleaning solvents are toxic
if inhaled. Minimize your risk by
only using these products in a
well ventilated area.

drawing with measurement details
to help visualize the operation. This
will reduce the risk of making errors
during the operation.
Two Circular Slots
In this example, you will cut two 92°
circular slots in a round workpiece,
as illustrated in Figure 13.
92º
To make five evenly spaced holes:
Radius
1.125"
1. Use the handwheel to rotate the
rotary table to the 0° mark on
the rotation scale, then tighten
both table locks.
Start
Here
0.25"
2. Drill the first hole.
Figure 13. Layout for creating two
circular slots.
3. Unlock the table, then turn
the handwheel 18 full turns.
This will rotate the rotary table
to 72°, as displayed on the
rotational scale.
To make two circular slots:
1. Use the handwheel to rotate
the rotary table to the 0° mark
on the rotational scale, then
tighten the table locks.
important: Be careful not to pass the
handwheel scale 0° mark on the
last turn. If you go past the 0°
mark, reverse the handwheel
one full turn, then try again.
This will eliminate any backlash
error that occurs when reversing
the handwheel direction.
2. Move the mill table to the left
1.125" along the X-axis so that
the spindle is at the starting
point above the lower end of the
upper slot.
3. Install a 1⁄4" end mill in the mill
spindle, then make a 0.083"
deep hole (approximately 1⁄3 the
cutter diameter).
4. Lock the table in place and drill
the hole.
5. Repeat Steps 3–4 to produce
the third hole at 144°, the fourth
hole at 216°, and the fifth hole
at 288°.

4. With the end mill continuing
to cut, turn the rotary table
handwheel clockwise 23 full
turns (92°), using care not to
pass the handwheel scale 0°
mark on the last turn.
6. Make a 0.083" deep hole, then
with the end mill continuing
to cut, turn the rotary table
handwheel clockwise 23 full
turns to begin the second 92°
slot.
5. Raise the end mill from the
workpiece, then rotate the
handwheel clockwise 45 full
turns (180°), making sure not
to pass the 0° mark. This will
bring the cutter to the starting
point of the second slot.
7. Raise the end mill, rotate the
rotary table clockwise back to
the 0° mark on the rotational
scale, then take an additional
0.083" deep cut.
8. Repeat Steps 4–7, increasing
the depth of cut by 0.083" each
time, until the final depth of cut
is reached for each slot.
note: Rotating the rotary table in
only one direction throughout
the operation will remove any
error from backlash.

Maintenance Schedule
Cleaning & Protecting
For optimum performance from
your rotary table, follow this
maintenance schedule and refer to
any specific instructions given in
this section.
It is essential that the rotary table
be cleaned after every use. DO
NOT use compressed air to clean
your rotary table. Chips or debris
may become lodged between the
moving parts, reducing the life and
accuracy of the tool. Instead, use a
stiff-bristled brush to remove the
chips and swarf, then wipe down
the machined surfaces with a clean
shop rag before applying a thin
coat of light machine oil to prevent
corrosion.
Daily Before Use
•
Lubricate the ball oilers
(Page 17).
•
Check/resolve any unsafe
condition.
Daily After Use
•
•
•
Clean the rotary table.
Dress the machined surfaces.
Lubricate the machined surfaces
to prevent rust.
Surface Care
Nicks, dings, and scratches on the
machined surfaces of the rotary
table can have an adverse effect
on accuracy and may damage the
workpiece or mill table.
Semi-Annually
•
Disassemble and clean the
internal cavity of the rotary
table, then lubricate the worm
gear and shaft (Page 17).
Prior to use, dress or "stone" these
machined surfaces with a fine
sharpening stone. A few strokes
of the stone on the rotary table
surface, the machined base and
back, and the mill table will help
to ensure longevity and accuracy.
Make sure to thoroughly wipe these
surfaces clean to remove any dust
generated from the process, then
apply a thin coat of light machine oil
to prevent corrosion.
Tip: After stoning and wiping down
the surfaces, run your fingers lightly
across the surfaces to detect any
irregularities.

M A i n T E n A n C E
important: Use an oil can or gun
that has a plastic or rubber tip.
Metal tips can damage the ball and
spring inside the oilers.
Lubrication
The recommended schedule
on the previous page for the
lubrication tasks is based on
light-to-medium usage. Keeping
in mind that lubrication helps to
protect the value and operation
of the rotary table, these
lubrication tasks may need to be
performed more frequently than
recommended, depending on
usage.
Clean away debris and grime from
around the ball oilers, then depress
the ball with the oil can tip to add
oil until it is seen exiting between
the parts. Clean away any excess
lubricant, then rotate the table at
least one full revolution to evenly
disperse the lubricant.
Worm Gear & Shaft
To gain access to the worm gear and
shaft for cleaning and lubrication,
you need to remove the table from
the cast iron housing.
Failure to follow reasonable
lubrication practices as
instructed in this manual could
lead to premature failure of the
rotary table components and will
void the warranty.

4. From the back of the rotary
table, loosen the spindle lock
collar cap screw (see Figure 16
on the previous page).
Spindle Preload
Setting the spindle preload on the
rotary table affects the accuracy and
ease of use during operation.
5. Loosen the lock collar at least
two full turns to remove any
preload.
Keep in mind, that too much preload
will make table rotation difficult
and will cause pre-mature wear of
the gears and mating surfaces of
the table. Conversely, not enough
preload may result in reduced
accuracy. Use your best judgment
when setting the spindle preload on
the rotary table.
6. Rotate the table by hand as you
re-tighten the lock collar. When
it becomes difficult to turn the
table, back off the lock collar
slightly until the table rotates
freely again, then, while keeping
the lock collar from rotating, re-
tighten the lock collar cap screw.

7. Use the backlash adjustment
ring to re-engage the worm
shaft and gear, then test the
table rotation by using the
handwheel.
To set the rotary table spindle
preload:
1. Make sure the table locks are
loose.
2. Use the backlash adjustment
ring to disengage the worm
shaft from the worm gear so
that the table can be freely
rotated by hand and not the
handwheel.
— If you are not satisfied with
the table rotation, repeat
this procedure to re-adjust
the preload until you are
satisfied with the results.
3. Position the table in a vertical
position so that both the front
and the back are accessible.
