The cueing lever lifts the tonearm but when I go to lower it on the song I want it drops really fast. Does anyone know how to add oil to the LAB 400 tonearm cueing mechanism? I already looked at the service manual and it just shows an exploded view of the parts but does not show or tell you how to replace the oil. I already have the silicone oil I just don't know how to get it in there.

Thanks.
