INSTALLATION OF ARM ANCHORING YOKE
At a height of 2.5 m from the ground, move 50 mm to the right from the CENTRE and mark the first hole
there (Fig. 2). Start drilling the hole (diameter 16 mm, depth 90 mm). This hole matches the upper right hole
in the yoke (Fig. 3). Place the pin and slightly screw it in. Mark the other holes using a spirit level to get them
parrallel (Fig. 4). Move the yoke and start drilling, place pins, and fasten all elements after checking they are
parallel with a spirit level.Before installing the arm check that the pins firmly hold the arm base (Fig. 5 – Fig.
6).
