Fig. 4 Connection of the arms with shaft bracket: 1 – tubular shaft; 2 – arms, 3 – shaft bracket.
NOTE! The correct procedure for mounting the shafts in the arm holders
requires that the bolts be evenly tightened diagonally, so that the entire
plane of the arm holders is adjacent to the plane of the shaft clamp profile.
This provides the most secure way of connecting the shaft arms to the
machine!
