When the right tension is reached: secure the contra nuts and the three bolts for support. Reassemble in the same manner.
PLEASE MAKE SURE YOU CHECK THE TENSION OF THE BELT AFTER THE FIRST 15 HOURS OF OPERATION
User Manual
Figure 9.5.8
Completely dismount the tensioning device (Fig.9.5.1). Make 2 marks on the dismounted belt
that are exactly 10 cm from each other (belt without tension) (Fig.9.5.2). The purpose is to
measure 10.2 cm on the belt in tension for 2% tension , a maximum of 2.5% is allowed (a
maximum of 2.5% is allowed). ATTENTION: NEVER "OVER" TENSION THE BELT, THE BELT WILL
BE DAMAGED AND IT WILL NEVER RECOVER ITS ORIGINAL TENSION
Mount the belt back around the planetary pulley; see that the belt is behind the driving pulley
(Fig.9.5.3). Put the belt around the left roller of the tensioning device (Fig.9.5.4). Put the
tensioning device back in place and pull the belt from the roller on the right side (Fig.9.5.5). Put
the belt around the driving pulley (Fig.9.5.6). Begin to tension until the measure of 10 cm
between the marks becomes 10.2 cm (Fig.9.5.7) (Fig.9.5.8). Tighten the tensioning device while
turning the bolt move the planetary head so the belt can slide. (Fig.9.5.8). Do not forget to lock
the tensioning device (Fig.9.5.9).

Open the cover to reach/check the belt and tension device (Fig.9.6.1).
While tensioning, regularly check the tension. Push the belt down with
a pressure of 71N. This is approximately 7 Kilograms or 15 pounds, with
this pressure the belt should move 3.5‐4 mm or 1/8". It is
recommended that the tensioning of the belt be measured with
Optikrik II device (measuring range: 500‐1400N) (Fig.9.6.2). The original
pressure P=1400N and after working a while, P=1100N.
ATTENTION:NEVER "OVER" TENSION THE BELT, THE BELT WILL BE
DAMAGED AND IT WILL NEVER RECOVER ITS ORIGINAL TENSION
Loosen the contra nuts (Fig.9.6.3), lightly loosen the three bolts of the
tension device (Fig.9.6.4), and adjust the tension with the nut seen in
(Fig.9.6.5).
