ELECTRICAL CONNECTIONS
WARNING: Make sure unit is off and disconnected from
power source before inspecting any wiring.
The motor is installed and wiring connected as illustrated in
the wiring schematic (see Figure 8).
The motor is assembled with an approved three conductor cord
to be used on 120 volts as indicated. The power supply to the
motor is controlled by a single pole locking rocker switch.
The power lines are inserted directly onto the switch. The
green ground line must remain securely fastened to the frame
to properly protect against electrical shock.
• Remove the key to prevent unauthorized use.
Refer to Figures 9 - 75.

WARNING: Operation of any power tool can result in foreign
objects being thrown into the eyes, which can result in severe
eye damage. Always wear safety goggles complying with
Unites States ANSI Z87.1 (shown on package) before com-
mencing power tool operation. Safety goggles are available at
Sears retail stores or catalog.
CAUTION: Always observe the following safety precautions:
SAFETY PRECAUTIONS
• Whenever adjusting or replacing any parts on the tool, turn
switch OFF and remove the plug from power source.
• Recheck all locking handles. They must be tightened securely.
• Make sure all moving parts are free and clear of any
interference.
• Make sure all fasteners are tight and have not vibrated loose.
• With power disconnected, test operation by hand for clear-
ance and adjust if necessary.
• Always wear eye protection or face shield.
• After turning switch on, always allow the spindle to come
up to full speed before turning.
• Be sure motor runs clockwise when viewing spindle exten-
sion from the left end (outboard side of headstock).
• Keep hands clear of spindle, centers, faceplates and other
moving parts of machine.
• For optimum performance, do not stall motor or reduce
speed. Do not force the tool into the work.
ON-OFF SWITCH
Refer to Figure 9.
Power supply to the lathe is controlled by the locking rocker
switch and speed control knob. To turn lathe on:
• Make sure the speed control knob is in the OFF position.
• Switch on the rocker switch. This will provide the power sup-
ply to the IC and operate the IC fan.
• Turn the speed control knob on (turn knob clockwise).
To turn lathe off:
• Turn the knob counterclockwise to the OFF position. This will
stop the spindle rotation.
• Switch off the rocker switch.
NOTE: Always turn the speed control knob to OFF position
before switching off rocker switch.
CAUTION: The lathe will not resume operation if speed con-
trol knob is not reset to OFF position before switching on
rocker switch.
To reset the speed control knob:
• Turn speed control knob to the OFF position.
• Make sure rocker switch is switched off.
