Example: a complete registering device weighing at 3 kg together with the head is
multiplied by 3, thus, a counterweight of about 9 kg should be applied (considering the 2
kg weight of the neck).
Before mounting the weights, the top part of the grip should be untightened, the neck
should be placed on the lower part, and next the top element should be placed back and
tightened fast with the blocking knob.
Assembling the weights should be matched with the assembly of the head and the
registering device. The installation should be conducted with the jig remaining as close to
the point of equilibrium as possible (see page 6).
Further, install the flexing wire. In order to do so, mount a mast on the axis of the jib
(Fig. 7).
The flexing line of the crane in the front part is placed on a knob which block the position
of the last segment of the arm (Fig. 8), and in the rear part it is placed on the knob which
blocks the neck of the counterweight (Fig. 9).
In order to acquire the proper flex, use the "click-type" tensioner in the central part of the
wire (Fig. 10).
