Balancing of the tonearm:
Fix cartridge pins. Add counterweights to the lower threaded carrier, starting with the longest
counterweight, then a plastic ring and another counterweight, until the tonearm is roughly
balanced. Be sure to fit the plastic rings that separate counterweights and, at the same time,
allow them to fit together. (See Fig.2 and counterweight configuration)
Knowing the approximate mass of the cartridge, enables choice of the correct configuration
of different counterweights. Aim for roughly zero balance. Even if the counterweights are not
screwed to the end, as long as you rotate two against each other, they will be fixed on the
thread. The main long counterweight (28 mm) remains fixed on the tonearm. You can use
any mix as long as you can achieve the desired tracking force.
Counterweight configuration:

Move the small upper counterweight for more precise balance, by rotating. The tonearm's
centre of gravity is chosen to be around the height of vertical rotation. Therefore balancing
the tonearm to zero is very difficult. Adjust it to be roughly balanced and increase tracking
force with smaller counterweight.
If this is too loose, hold the front part of the counterweight and rotate the rear part until there
is a tighter fit, or lock it into position on the threaded carrier. Opposite rotation will make the
smaller counterweight looser. (Fig. 2)
