Electric Motor
Your lathe is equipped with a 3 phase AC industrial grade motor. The motor is fan cooled. If the lathe has run
for a long time on slow speed the motor may stop as the fan is not turning fast enough to cool the motor
sufficiently. Allow the motor to cool before continuing.
Inverter
Your lathe is equipped with an industrial grade variable frequency
drive, also known as an “inverter”. The inverter takes normal
household current and converts it to industrial 3 phase power. When
you change the spindle speed dial on the pendant controller, the
inverter changes the frequency sent to the motor which changes the
motor speed.
The inverter is factory set with parameters that most turners will like.
The inverter manual shows how to change the settings. Changing
certain settings will prevent your lathe from running properly, if at all.
Other settings, such as ramp up and ramp down speeds can be set to
your liking. Your inverter may be equipped with a fan that runs for a
moment or two after the motor stops.

It is strongly recommended not to change any inverter parameters until you are very familiar with your
lathe and are familiar with inverters.
Pendant Controller
The corded pendant controller is used to control major functions of your lathe. It has strong rare earth
magnets on the back so it can be moved and attached to sections of your lathe as needed.

Speed
Twist the knob to the left to go slow and to the right to go fast.
Aproximate speeds are indicated. Be sure to know the belt
position to make the most of this information.
It is a good idea to set the speed at its slowest setting and
gradually increase to the desired speed every time you start
the lathe.

Twist the swith to the right to go forward
Twist the switch to the left to go in reverse
You can change direction with the lathe is running. The lathe
will slow down, stop, and then reverse direction. This will not
harm the inverter or motor.
Use caution when turning in reverse. Your work holding
device (chuck, faceplate, etc.) should be secured to the
spindle if reverse is used.
