Overhang Adjustment; Lead-Out Adjustment; Lead-In Adjustment - JVC QL-F300 Service Manual

6-(2) Overhang Adjustment (Fig. 27)
Adjust the overhang as shown, aligning the center lines of
the cartridge and the headshell. Leave 32 mm between the
stylus tip and the edge of the headshell as shown. An error
of +1 mm will not degrade performance.

The optimum clearance between the stylus tip and the plat-
ter mat is about 8 mm when the tonearm is resting on the
tonearm elevator (with the UP/DOWN knob switched to
the UP position). Turning the adjusting screw clockwise
lowers the height of the tonearm elevator and turning it
counterclockwise increases it.
