5.6 ACCESSORIES ON THE BEAM

The accessories on the beam must be considered
when choosing the balancer spring (single or double).
The accessories on the beam must be fitted before
balancing the beam. If the accessories are added
or removed later it may be necessary to change
the spring. After a modification of the beam, it is
necessary to balance it again.
The spring appropriate for the configuration and
length of the beam is defined in the balancing charts
(see
