unlcip the rear cover it just pushes on.
then undo the three screws underneath make a note of the postion of the attatchment part as it only goes in one position and can be put back 3 ways.
then lift and push the top cover forwards over the front lug.
remove the other plastic covers first though pushing  red lever aside.
it will be mucky in there though.
