Wurlitzer Niagara 5

Hi
I have acquired this type of jukebox manufactured in 1982, the sound, selection are all fine however the tone arm seems to be malfunctioning. When a track is selected and the gripper arm brings the record to the turntable the tone arm moves away from the turntable ( about 2-3 cm). When the record has been placed on the turntable the tone arm then is too far away to land correctly on the turntable. Can anyone help with this problem. ( i have carried out some preliminary lubrication on the mechanics blow the tone arm.
regards
Brian

sorted it, seems with this type of machine the rest position of the needle is to the left of the brush
thanks
