N Move the vehicle forwards, in order to be able to check the vertical oscillation of the chain even when the wheel turns; the slack must be constant in all the rotation phases of the wheel. If in some positions the slack is higher than in others, this means that there are crushed or seized links. To prevent the risk of seizures, lubricate the chain frequently, see p. If the slack is uniform, but higher than 20 mm, adjust it, see p.
