As you can see in the picture there is a small hole on the arm base. With the arm in the approximate spot of the beginning of the record (stylus guard on, lifter up or stylus removed for safety), insert a long thin flat blade screwdriver into the hole. Wiggle it until the blade seats in the groove. Turn it slightly-1:00 increments at a time, noting which way you turned it. Remove the screwdriver and start a record-you must remove it or the arm won't move. Compensate accordingly if you need to turn it more the same way or the opposite to get your desired spot. Double check that it lifts at the end of the side as well and Bob's ur Uncle.
