If you need to lubricate, remove the dustcover and then the tonearm cover can be lifted straight up to gain access the dial and gear. At that point you can check the balance of the arm and the rear counterweight adjustment. You should not need to track at 1.2g. Sometimes the arm cover can get pushed so that it binds the arm. Its height should allow the screw to be centered and the arm to move freely when lowered.
