Variable Speed Control
The variable speed control box contains the
electrical connections to the motor, and has three
external controls.
WARNING
Always set the speed control knob to its
lowest setting before starting lathe. Never
start a workpiece at maximum speed.
Power Switch (A, Fig. 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, Fig. 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 (up to
maximum 3900 RPM). Counterclockwise decreases
speed.
Reset Button (C, Fig. 9) – contains 8-amp 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.
Changing Spindle Speeds
The variable speeds of the lathe are controlled by
the speed knob on the control box as well as the
position of the belt on the pulleys.
1. Disconnect machine from the power source
(unplug).
2. Pull open the control box at the left side of the
base (A, Fig. 10), and the access door at the
back side of the headstock (A, Fig. 11) to
expose the pulleys.
