Spindle Speed Range Lever
Alternately engages drive gears to produce high
or low range operation in the headstock.
Spindle Speed Lever
Controls the spindle speed only and has no effect
on the gearbox speed or the apron feeds.
Feed Direction Lever
Controls the forward and reverse direction of the
carriage and cross feed. When this lever moved
left or right, the direction of the quick change
gearbox, feed rod, and lead screw reverse direc-
tion, but spindle direction is unaffected.

Power Light
When the lathe is connected to power, it is not
necessarily ready for use. only when the stop but-
ton is twisted clockwise and popped-out, and the
on button has been pushed will the power light
illuminate and indicate that all electrical controls
are "live" and ready for use. Just because the
power light is oFF, do not assume that the lathe
is safe for electrical work, general adjustments,
or workpiece changes. you must always discon-
nect the lathe from power before attempting any
of these tasks.
Power Button
prevents accidental start up. every time the stop
button is pressed in and then reset, the power but-
ton must be pressed. if there has been a power
Jog
outage while the lathe was operating, when power
Button
is resumed, the power button must be pressed to
reactivate the power to the control panel. if the
stop
Button foot brake is pressed, a limit switch will cut power
to the motor immediately.
Cutting fluid ON/OFF Switch
toggles the cutting fluid pump ON or OFF. never
turn the cutting fluid pump on and let it run while
the reservoir is empty, or pump damage may
occur.
Feed Speed Dials
engage either the feed rod or leadscrew, and set
the apron speed for threading, turning, or facing
operations.
Stop Button
Cuts power to the spindle motor and the control
panel. no braking occurs and the spindle, chuck,
and workpiece wind-down naturally. After being
pressed, the stop button stays pushed in until it is
reset by twisting the knob clockwise until it pops
back out.
Jog Button
Bumps the motor ON and OFF so partial spindle
rotation occurs in reverse. useful when the lathe
is stopped in low range and the lathe gear reduc-
tion makes it difficult for the machinist to rotate
the chuck by hand in order to reposition a chuck
or workpiece.
Note: In order to use the jog button, the Spindle
ON/OFF lever must be in the central or OFF posi-
tion.
