Check the V-belts
– Examine the entire circumference of the V-belt for damage.
– Replace damaged V-belts.
– With new V-belts check the V-belt tension after a running time of
15 minutes.
– To check the V-belt tension use the V-belt tension measuring
gauge (29 02691).
– Lower the indicator arm (1) into the gauge.
– Apply the guide (3) to the V-belt (2) between two pulleys,
whereby the stop should be resting against the side of the
V-belt.
– Press the push button (4) evenly under a right angle to the
V-belt (2), until the spring is noticeably released.
– Lift the measuring gauge carefully without changing the posi-
tion of the indicator arm (1).
– Read the measuring value on the intersection (arrow) of scale
5 and the indicator arm (1).
