THORENS TD 309 - Manual (Page 25)

Slide the black guide sleeve onto the spindle. Then
loop the drive belt around the sub-platter and the motor
pulley.
➔ Fig. 2
Avoid oil or grease coming into contact with the belt,
pulley or sub-platter. If necessary, these parts can be
cleaned with glass cleaner or pure alcohol and a lint-
free cloth.
The belt tension is factory-adjusted. If it needs to be re-
adjusted (e.g. to compensate for gradual belt stretch),
loosen the locking screw of the eccentric motor support
ring and carefully rotate the ring.
➔ Fig. 3
If the belt tension is changed, the motor speed will
need to be reset.

The drive belt should be replaced every few years.
Thorens replacement belts are available from any
Thorens dealer or distributor.
