It is recommended that the tensioning of the belt be measured with Optikrik II Device (Measuring range: 500‐1400 N) (Fig. 9.7.8) . For
a new belt the tensioning force is 650N, and the fastening force is 520 N.
ATTENTION: NEVER "OVER" TENSION THE BELT, THE BELT WILL BE DAMAGED AND IT WILL NEVER RECOVER ITS ORIGINAL TENSION
Tighten the two nuts on the sectors and contra nut on the tensioner ( Fig. 9.7.10). Put the seal ring on the bottom cover and close
