2.2.4.1. Procedure of check
Fig. 2.74. Check of a tension of a driving belt

Check the provision of a tag of the indicator of an automatic natyazhitel of a driving belt (fig. 2.74).
If the provision of a tag does not meet standard, the driving belt needs to be replaced.

NOTE
In everyday occurences check of a deflection/tension of a driving belt is not required as the tension of a belt is provided with an automatic natyazhitel.
