Models with the vertical counterweight mount the
●
mounting support at about 460mm (approximate value:
Fig. 5) from the bottom of the shaft.
Support the counterweight of the models with horizontal
●
counterweight until it is in an oblique position (Fig. 4).
In the model with vertical counterweight keep a distance
