Additional Safety for Wood Lathes
MAIN INJURY HAZARDS: Death or crushing injury from getting entangled in rotating spindle
or workpiece; death, blindness, or broken bones from being struck by a workpiece that breaks
apart or comes loose during rotation, turning tool kickback, or flying wood chips. To minimize
your risk of these hazards, always heed the following warning information:
INTEGRITY OF STOCK. Verify each workpiece
is free of knots, splits, nails, or foreign material
to ensure it can safely rotate on spindle without
breaking apart or causing turning tool kickback.
WORKPIECE PREPARATION. Before mounting,
cut off waste portions with a bandsaw or other tool
to ensure workpiece has no large edges to catch
turning tool, and it will rotate without dangerous
wobbling.
SECURING LOCKS. Verify tool rest, headstock,
and tailstock are secure before turning lathe ON.
SECURING WORKPIECE. An i mp rop er l y se cu red
workpiece can fly off spindle with deadly force.
Use proven setup techniques and always verify
workpiece is well-secured before starting lathe.
Only use high-quality fasteners with non-tapered
heads for faceplate attachment.
TOOL SUPPORT. An improperly supported tool
may be grabbed or ejected. Adjust tool rest
approximately
above workpiece center line to provide proper
support for turning tool. Firmly hold turning tool
with both hands against tool rest.
TOOL KICKBACK. Occurs when turning tool is
ejected from workpiece with great force, striking
operator or bystanders. Commonly caused by
poor workpiece selection/preparation, improper
tool usage, or improper machine setup or tool rest
adjustment.
ADJUSTMENT TOOLS. Remove all chuck keys,
wrenches, and adjustment tools before turning
lathe ON. A tool left on the lathe can become a
deadly projectile when spindle is started.
1
⁄4" away from workpiece and 1⁄8"
EYE/FACE PROTECTION. Always wear a face
shield and safety glasses when operating lathe.
PROPER APPAREL. Do not wear gloves, necktie
or loose clothing. Keep keep long hair away from
rotating spindle.
SPEED RATES. Select correct spindle speed for
workpiece size, type, shape, and condition. Use
low speeds when roughing or when turning large,
long, or non-concentric workpieces. Allow spindle
to reach full speed before turning.
NEW SETUPS. Test each new setup by starting
spindle rotation at the lowest speed and standing
to the side of the lathe until workpiece reaches full
speed and you can verify safe rotation.
ROUGHING. Use correct tool. Take light cuts,
use low speeds, and firmly support tool with both
hands.
SHARP TOOLS. Only use sharp turning tools—
they cut with less resistance than dull tools. Dull
turning tools can catch or grab and pull your
hands into the rotating workpiece.
STOPPING SPINDLE. Always allow spindle to
completely stop on its own. Never put hands or
another object on spinning workpiece.
ADJUSTMENTS/MAINTENANCE. Make sure
wood lathe is turned OFF, disconnected from
power, and all moving parts ar e c om pl et el y s to pp e d
before doing adjustments or maintenance.
MEASURING WORKPIECE. Only measure workpiece after it has stopped. Trying to measure a
spinning workpiece increases entanglement risk.
SAFE CLEARANCES. Before starting spindle,
verify workpie ce has adequate clearanc e by handrotating it through its entire range of motion.

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.
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the 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
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:
Grounding & Plug Requirements
