ADJUSTMENT
ADJUSTMENT OF HEADSHELL :
The headshell attached to the tonearm should not be
inclined either to the right or to the left. If necessary, loosen
the two screws on the bottom of the tubular arm and adjust
the headshell. Be sure that the stylus is normal to the record
surface.
ADJUSTMENT OF AUTO-RETURN
Remove the turntable to set the tone arm in the reset
position
(1).
Under
this
state,
move
the
gear
so
that
the
tip
of lever M16 intermeshes with the withdrawn part of cam
for
main
gear.
Besides,
lower
trip
lever
M13
and
trip
lever
M24 pushed toward the arrow marks A and B, respectively.
Turn pipe assy. M6 toward the arrow mark C to set so that
the convex part of pinion and the tip of claw for the
egagement lever M12 contact each other (arrow mark a).
Next, move the tone arm (toward arrow mark D). When
the distance between the center shaft of turntable and the
needle tip becomes 64 thru 65 mm (2), insert a blade
screwdriver into part C, and adjust by turning it clockwise
or counterclockwise so that the tip of trip lever M24 begins
to contact with lower trip lever M13 (arrow mark b).
Finally put on the turntable, and check the performance of
auto-return.
