Operation
Working alongside trenches
Danger of damaging piston rod A of the boom cylinder when working
alongside trenches, slopes, etc. and operating the stabilizer blade and the
boom incorrectly.
• Always use stabilizer blade B for stabilization during excavation work
• Ensure that stabilizer blade B never touches piston rod A (Fig. 254).
• If you perform deep excavations with stabilizer blade B at the front, ensure
that piston rod A does not touch or rest on stabilizer blade B (Fig. 254).

Tipping hazard of machine alongside trenches!
Can cause serious injury or death.
• Use this work position only in an extreme emergency since the machine
can tip over forward into the trench.
• We recommend using the first work position (Fig. 254) described above
and to ensure that piston rod A does not touch stabilizer blade B under any
circumstances.
