7.6 V-belt tension
The correct V-belt tension is of utmost importance in order to obtain a
perfect power transmission and to reach the usual working life of the
V-belt. Too low or to high tension causes frequently a premature
breakdown of the V-belt. Excessive belt tension results in damaged
bearings at drives or scarifying drums.
Check the tension of the V-belt by pressing the thumb on the belt. The
belt has the correct tension if you can press it in for approx. 10-15 mm
(Fig. 7.6.1).
