fig. 3
Note: The lathe is fitted with a no-volt On/Off switch which automatically switches off if the supply is interrupted (power cut, socket
switched off etc.) thereby preventing unexpected, and therefore dangerous, start-up when the supply is reconnected.
4.1. To switch the lathe on open the switch cover and press the “I” button. Allow the cover to close but do not press fully shut and latched
as this will switch off the lathe.
4.2. To switch the lathe off normally open the switch cover and press the “O” button. In an emergency push the red ‘button’ on the switch
cover. This will stop the lathe and also latch the switch cover closed, with the “O” button depressed. The lathe cannot be restarted until
the switch cover has been unlatched by sliding the red button upwards.
