The torsion spring is set at a tension of 410‐
440 gr. in the factory. This tension is
measured at the front end of the impact
lever, and must under no circumstances be
exceeded. If necessary, tighten the spring by
enlarging the hook at the lower part of the
impact lever bearing (see sketch under point
6.2.b).
