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
