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.

Additional Safety for Mills
UNDERSTANDING CONTROLS. The mill is a
complex machine. To reduce the risk of injury,
make sure you understand the use and operation
of all controls before you begin milling.
SPINDLE SPEED. To avoid tool or workpiece
breakage that could send flying debris at the
operator and bystanders, use the correct spindle
speed and feed rate for the operation. Allow the
mill to gain full speed before beginning the cut.
STOPPING SPINDLE. Always allow the spindle
to stop on its own. To reduce the risk of lacerations, entanglement, or breakage debris, DO NOT
attempt to stop the spindle with your hand or a
tool.
SAFETY ACCESSORIES. Flying chips or debris
from the cutting operation can cause eye injury or
blindness. To reduce this risk, always use a face
shield in addition to your safety glasses when
milling.
WORK HOLDING. Attempting to mill a workpiece
that is not properly secured could cause breakage debris to fly at the operator. Before starting
the machine, be certain the workpiece has been
properly clamped to the table or secured in a vise.
NEVER hold the workpiece by hand during operation.
CH I P C L E AN U P. Waste chips created by the milling operation are sharp and hot and can cause
cuts or burns. Using compressed air to clear chips
could blow them into your eyes or drive them deep
into the working parts of the machine. Use a brush
or vacuum to clear away chips and debris from the
machine or workpiece. NEVER clear chips while
the spindle is turning.
MACHINE CARE & MAINTENANCE. Operating
the mill with excessively worn or damaged parts
increases the risk of accidents that could cause
serious injuries. A mill that is maintained poorly
will produce poor results. To reduce this risk,
maintain the mill in proper working condition by
ALWAYS promptly performing routine inspections
and maintenance.
CUTTING TOOL USAGE. Cutting tools have very
sharp leading edges—handle them with care!
Using cutting tools that are in good condition helps
to ensure quality results and reduces the risk of
personal injury from broken tool debris. Inspect
cutting tools for sharpness, chips, or cracks before
each use. ALWAYS make sure cutting tools are
firmly held in place before starting machine.
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.
-8-
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 electrican 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.)

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.
We do not recommend using an extension cord
with this machine.
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:

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!
