to remove the rods first (see page 56). To do this, check that the
securing buttons are restraining the insert and open the lid assembly
and rest it against the top cover assembly. Then, using a 2.5mm hex
key, release the rod clamping screws and withdraw the rods. Close the
lid assembly and release the insert by turning the securing buttons.
Now remove the insert.
