Variable Speed Control
The variable speed control box contains the electrical connections to the motor, and has three external
controls.
Always set the speed control knob to its lowest setting before starting lathe. Never
start a workpiece at maximum speed.
Figure 9
Power Switch (A, Figure 9) – controls electrical power to lathe motor. Flip toggle switch on ON position to
start the motor. The lathe will begin turning and driving the headstock spindle. The lathe will reach full
speed in about 1 to 3 seconds. The time it will take the motor to reach the speed set by the speed control
knob depends on the size and weight of the workpiece.
Move the switch to the OFF position to stop the lathe. Wait for the workpiece to come to a complete stop.
Speed Control Knob (B, Figure 9) – sets the speed of the lathe to suit the weight of the workpiece or type
of tool being used. After lathe is started, turn knob clockwise to increase spindle speed. Counterclockwise
decreases speed.
Reset Button (C, Figure 9) – contains overload protection. If the lathe stops suddenly during operation, or
does not start when the power switch is set to ON, an overload condition may have occurred. Flip the
power switch to OFF, and push the reset button. Then re-start the lathe.
