Running A Program
NOTE:
Press the START/STOP button to initiate the
program. If the Lift platform is in the down position pressing

closed position. Make sure your sintering trays are in
position in the center of the firing platform before initiating
the firing cycle.

of Stage LEDs will be ON, and the Green “Ready” LED will
be lit to signify the firing cycle is complete.
Technically the
firing cycle is still active until you press the Start/Stop
