Before the turntable can be used some preliminary activities have to be put into effect. 

 
 

1.1 How to install the platter (B): 

The platter has to be positioned in perfect alignment to the sub platter. Settle down the platter carefully 
without tilting it. The platter should lie flush on all 4 rubber bumpers of the sub platter. Turn the platter 
clockwise carefully to see that there’s no radial runout. 
 
 

1.2 How to install the belt (C): 

Take the belt out of the beauty carton and put it circumferential around the platter. Now pull the belt in 
direction of the motor and pull it over the motor pulley. Check if the belt runs centered on the pulley by 
carefully turning the platter clockwise. That should be the case after 2 turns at the latest. 
 
 

1.3 How to install the tone arm weight (D) on the tonearm: 

Place the tone arm weight onto the thread of the tone arm and turn it clockwise 
until  the  tone  arm  is  floating.  Check  this  by  carefully  releasing  the  tone  arm 
from time to time while turning.  
If the tone arm isn’t spreading up anymore the floating point has been reached. 
If the tone arm is spreading down the weight has been turned too wide and 
should be turned back counterclockwise a bit. 
 
 

1.4 How to adjust the tracking force: 

From the floating point turn the weight clockwise onto the thread exactly 3 ½ 
turns. This results in a tracking force of appr. 1.4 g. The tone arm is now ad-
justed properly. 
 
 

1.5 Installing the anti-skating weight (E): 

The anti-skating weight should be installed as shown on the picture above. 
 
 
 

 

1.6 Putting-on the felt mat: 

The last step is to put the felt mat onto the platter if not done already. 
The turntable is ready for use now and can be connected.
