Chain tension
Check the chain tension in three or four positions,
turning the crank a full revolution.
The ideal chain tension has been achieved if the
chain
can be pushed a maximum of 2 cm in the
middle between the pinion and the toothed wheel.
The crank must also turn without resistance.
Figure 23:
Checking the chain and belt tension
Excessive chain tension increases wear.
If the chain tension is too low, there is a risk that the
chain
will slip off the
chain wheels
.
Check the chain tension once a month.
NOTICE
If the
chain
can be pushed more than 2 cm, the
chain
will need to be tensioned again by the
HERCULES specialist dealer.
If the
chain
can only be pushed less than 1 cm, the
chain
will need to be relieved of tension accordingly.
