Attach the measuring head in front of the toothed belt.
NOTE
The measuring point of the measuring pin must be in the middle of the two deflection pulleys.
The measuring pin should be at a maximum distance of 2 - 3 mm, from the toothed belt.
➠ Strike the toothed belt, to reach a stimulation of vibration of the open ended toothed belt.
➠ Stretch the belt over the fastening of the driving motor (compare: service manual) if the
frequency of the belt tension does not reach a value of 280 Hz +
10 Hz.
➠ Repeat these instructions until the belt tension is correct.
