Put the belt around the platter and the pulley. The pulley is equipped with 6 little grooves
fort the belt. Those with a smaller diameter are used for the speed 33 1/3 U/m, those with
the bigger diameter are used for the speed 45 U/m.
The middle groove is used for the exact speed. The upper groove increases the
speed a little bit, the lower groove reduces the speed a little.
Important:
Turn the platter now by hand, to ensure the perfect positioning of the belt around the
platter.
Please use for 110 Volt motors the 2-cut pulley (e.g. USA):
Place the pulley on the motor spindle. The distance between the pulley and the motor
housing should be approx. 1mm. Tighten the little screws inside the pulley with the
aluminium screwdriver provided.
Speed calibration:
Install the drive belt, first around the platter, then around the motor pulley. There are two
diameters on the motor pulley:
• smaller for 33 1/3 rpm
• larger for 45 rpm
To correctly adjust the belt tension, turn the motor around its axis. Proper tension will be
achieved through eccentric placement of the motor pulley or if you have enough space on
your platform, just change the distance between the motor and the turntable chassis. The
belt tension is correct if the belt can be deflected by approximately ¾inch by a finger.
