GB
Connect boom with the operator unit
• Push the adapter sleeve (A) to the stop onto the fine toothed gear shaft
(fig. D.3).
If you turn the operator unit by 90°, the installation depth is lessened by
150 mm. For this the reference point switch (B) has to be turned as well to
the foreseen position (fig. D.4).
• Put the boom in its right position to the adapter sleeve.
• Align the boom laterally.
• Push the boom onto the operator unit using slight pressure (fig. D.5).

Attention!
Do not use force!
If the boom is aligned parallel to the surface of the operator unit,
a short pull on the carriage is sufficient to lower the boom onto
the operator unit without force.
• Screw the boom to the operator unit using two clamp brackets (C) and
four hex screws SW 8 (D) (fig. D.6).
Mount suspension clamp to boom
