Optibelt belt tension tester (additional equipment)
There are three ways of holding the belt tension tester:
Hold the tester as shown in fig. A, B or C.
Place the tester on the free belt length, as closely to the centre as possible, and push the black indicator arm down-
wards.
Activate the tester carefully until it clicks; do not push after the click!
Now the belt tension (Tmin) can be read off the scale at the intersection on the front of the black indicator.
Increase/decrease the tension until the correct belt tension has been reached.
