Read tension force at the point of intersection of the upper side of the indicator arm (1) and the scale.
●
Before reading the values make sure that the indicator arm remains in its position.
If the value does not agree with the specified setting, the Powerbelt tension must be reajusted.

crankshaft.
●
Slowly push pressure pad (3) down until the
spring snaps out audibly and the indicator arm
moves upwards.
Continued pressing after the spring has snapped
out will result in an incorrect reading!
