1 - 

Open the transparent cover by pushing the two teeth in its

lowest corners to the direction indicated by the arrows.

4 - 

Close the transparent cover.

3 - 

Check the value of the new fuse to assemble, then fix it by

gradually and alternately fastening the two screws. This will
avoid voltage drops along the line and will make the device
perfect functioning easier.

2 - 

Remove the screws which fasten the fuse to eliminate

pieces of the broken one; prevent them from going into the
device.
