Setting values for the belt tension
The pretensioning force or the vibration frequency of the belt is decisive for
adjustment of the belt tension. For this, we recommend the use of the DM.16
belt tension meter from Facom or a frequency meter. If neither of these me-
ters are available, please contact your nearest
HATZ Service
.
