Mount SA-1.2 shaft through the Base hole
2-a
Carefully push the tonearm shaft through the hole in the arm base and
then fasten the set-screw with the hex key supplied with the tonearm. Be
careful not to over tighten!
2-b
Adjust the tonearm height to make the tonearm parallel with the
surface of the record when the stylus is touching the record. This is the
starting point, and further fine tuning may be necessary depending on
the geometry and the stylus type of the cartridge. Consult the cartridge
manufacturer for correct VTA and VTF!
2-c
The cueing platform has already been set at the correct height but can
be adjusted by using the supplied hex key.
Cartridge tracking force adjustment
3-a
Verify that the anti-skating knob (number 3) is set at 0 grams.
3-b
Ensure that the sliding tracking force adjustment knob (number 4 ) is
set to zero (the point furthest to the back of the tonearm and closest to the
pivot point).
3-c
After the cartridge is correctly adjusted for overhang, adjust the
counterweight (number 1) so that the arm is floating with the stylus
approximately 3-5mm clear of the vinyl record. Once this adjustment is
made, the counterweight should be xed by the set-screw located on the
side of the counterweight (number 2 below), using the supplied hex key.
3-d
Add tracking force by using the sliding counterweight located in the
middle of tone arm (number 4 below). As the middle counterweight slides
forward, the tracking force increases. The tracking force can be increased
to a maximum of 3.0 grams with the middle sliding counterweight pushed
all the way forward to the headshell end of the tonearm (each step is
equivalent to 0.5 grams x 6 steps, making 3 grams).
3-e
The auxiliary weight is 1.5 grams (see 5). If more than 3 grams of
tracking force is needed, as might be the case when playing 78 rpm
records, place the ancillary weight in the hole as illustrated in the drawing
(see 5). Only use this auxiliary weight if additional tracking force is needed!
If it is not needed, store it away in a safe place.
Note
Because the tracking force mechanism (see 4) of SA-1.2BCS is different
from a standard counterweight system, the use of a separate VTF gauge for
precise fine-tuning is recommended. The relative accuracy of the SA-1.2
tracking force mechanism is somewhat affected by the complex interaction
of the mass of the main counterweight, its position, the mass of the cartridge,
and the mass of the headshell. So, as is usual with all tonearms, you should
verify the desired tracking force with a calibrated VTF gauge.
Auxiliary counterweight stem
In case the standard counterweight is not heavy enough to
balance your cartridge/headshell combination, an additional
counterweight stem has been supplied to give additional mass,
and greater range of adjustment.

If the tracking force needed is 3 grams, set the middle sliding
counterweight at the mark for 3 grams on the weight gauge. If more
than 3 grams of tracking force is needed, use the auxiliary weight
of 1.5 grams, along with the counterweight, in order to secure your
desired tracking force. For instance, the ancillary weight of 1.5
grams, plus 2.5 grams of tracking force set by the middle sliding
counterweight, is equivalent to 4 grams total tracking weight.
