Working with the machine

with grabs require the machine operator to receive special instruction and training. sufficient training and practical experience.

Safe use of machines with tower elevation gravity of the machine will be displaced upwards in the vertical direction. The driving and work characteristics of the machine will thus be influenced persistently, e.g. through reduction of the dynamic stability. the machine must be aligned horizontally before use. In horizontal alignment, the centre of gravity of the uppercarriage is over the centre of the undercarriage, which reduces the risk of tilting. tilt despite being aligned! The following instructions are therefore to be observed at all times: When moving the machine:

holes and uneven surfaces jeopardize the stability of the machine. red machine characteristics (high centre of gravity) and environmental conditions. noeuvres. aking, accelerating and changing direction. ly be approached in the longitudinal direction in order to prevent unacceptable banking of the machine. slowly! When loading and unloading: the uppercarriage out of the transport position.
