Roller chain adjustments and repairs
The roller chains are located both on the front and back ends of the machine, as well as inside the ground
wheel. These must be kept equally tight. Stretched roller chains and worn tensioners must be replaced
well in advance. Pay attention to the accurate installation of the chain lock, see Fig. 42.
