Tensioning of the roller chain
It is necessary, to ensure correct functioning and
due to wear, that the roller chain is checked in
regular intervals and tensioned again, if
necessary.
The roller chain must be tensioned until it is
guaranteed that the chain runs smoothly, wear
elongation is compensated and the chain cannot
jump over.
Avoid a too severe pre-tension.
Setting of the chain-tensioning-wheel is made with
the existing screw.
