The normal belts on the market have different characteristics compared to the requirements of the
belts of the power of the engine is distributed to the different users through a system of transmis-
sion belts, each kept at the right level of tension by a tightener preloaded by a spring.
The standard belts on the market have different characteristics compared to the requirements of
the original spare belts, supplied by the authorised dealer. The latter are designed and manufac-
tured in close cooperation with the belt supplier and the machine manufacturer.
The table emphasises the reasons why it is important to choose an original belt, useful when mak-
ing such decisions.
