Daily Maintenance
Once the screws have been removed, lift the top cover up while holding onto the black box that the power
cord plugs into. This box is attached to the top of the machine so it will stay in position as you remove the
top cover.
The top cover can hang off the side of the machine without disconnecting the cable that connects it to the
circuit board. Or, if you feel more comfortable, you can easily disconnect the cable. Push the plastic tab
towards the cable, and then pull the connector out of the circuit board.
