GUIDE -BELT
MOTOR-PULLEY
All of the stationary parts of this machine are ideally
adjusted prior to shipment. However, the following
adjustments are necessary according to circumstances
involving usage:
(1) RETURN POSITION ADJUSTMENT
Remove turntable and loosen the plate holder metal
fitting (PLATE LOCK (20) ). This can be accomplished
after loosening the two installation screws (19) on
the table mount 2 or 3 turns. (Fig. 15) Because this
separates the table mount and the cabinet by a
considerable degree, the return position adjustment
screw (18) located on the reverse side of the PU Arm
becomes accessible. Adjust with plus driver (Fig. 14)
As shown in Fig. 14 when the adjustment screw is
turned to the right (in direction of solid line), the
return position is slowed (inside circumference ap-
proach) and when the adjustment screw is turned to
the left (in direction of broken line), the return posi-
tion is speeded up (outside circumference approach).
(When the adjustment screw is turned 1 revolution,
the position of the PU Arm stylus tip is changed by
about 8 m/m).
Always confirm this adjustment with a JIS specifica-
tion 30 cm LP record. Also while the turntable is
removed, confirm that the CLUTCH ASSY (4) begins
to move out when the PU Arm stylus tip is 64 mm
(R) to 70 mm (R) from the turntable shaft center.
CAUTION: If adjustment cannot be made without
turning the adjustment screw (18) more
than 2 revolutions, becausé this is likely
to be caused by improper installment
position of PLATE PU ASSY (10) and
TRIP (5), CLUTCH ASSY (4) etc. (by
position of other parts) check these points.
Also after adjustment, be sure to return
installment screws (19) to former position
and tighten.
SET SPEED SELECTOR
TO 45RPM POSITION.
(2) CYCLE CHANGE (MOTOR PULLEY CHANGE)
Cycle change is effected by changing the motor pulley.
50 and 60 Hz differentiation can be determined by
the groove on the 60 Hz pulley. (See Fig. 16)
_ While viewing horizontally as shown in the figure,
install so that the lower part of the motor pulley brim
and the lower part of the GUIDE belt are aligned
(Refer to figure).
(Set Speed Selector to 45 r.p.m. position).
When the player is turned ON and the turntable
rotates, if a rubbing noise from the belt can be heard,
(except while switching) and operation is not smooth,
further adjust pulley height by moving up and down
slightly and position for best adjustment.
