Turn the counterweight to the position which balances the arm, i.e: where the stylus is floating at about record height. Clip the arm back into its rest. Turn the tracking dial while holding the counterweight until '0' is aligned with the line on top of the arm. Check the arm is still balanced. If not you have moved the counterweight when setting the tracking dial, so re-balance the arm and re-set the tracking dial to '0'. Turn the counterweight clockwise (as you look at the dial) to the desired tracking force. Set the bias to the same value. (See General Installation for more information). Check the arm height is correct. The arm-tube should be parallel to the record surface. Adjustment can be made by loosening the arm height adjustment screw with a 4mm hexagon key, moving the arm to the correct height and locking the screw. To set the correct torque tighten the screw firmly using the alien key in position 1, then turn the key to position 2 and tighten no more than a further 1/8 of a turn.
