Caution
•

If faults are found, it is absolutely necessary to renew the
poly V-belt.
In the case of diesel engines, toothed belts which came
into contact with oil, brake fluid, fuel or reducing agent,
must always be renewed.
•
In the case of petrol engines, toothed belts which came
into contact with oil, brake fluid, fuel or coolant, must al‐
ways be renewed.
•
•
This can avoid breakdowns and malfunctions.
The replacement of a poly V-belt is a repair measure.
