still pretty easy.
put it on the edge of the shorty screwdriver (part of the jet tool if you have one).
Hold the jet on the screwdriver blade and find the hole (pretty far left in the 17mm hole next to the main jet and inside the white plastic baffle). Push it in, then screw it in.
No doubt there will be some choice words to be heard. ;-)
