that the Main Power Switch (178),
Forward/OFF/Reverse Switch (181) and
the variable Speed Control Knob (180)
are in their off positions.The variable
Speed Control Knob has an actual “0/
Off” position and will “click” when placed
in the “Off” position.

the Variable Speed Control Knob is
turned to the “0/Off” position before
restarting. Attempting to start the
lathe with the Speed Control Knob
(180) set at any speed other then “0/
Off” or attempting to start the lathe
out of sequence, will cause the fuse
