Ground characteristics
Danger of material damage if used on unsuitable ground.
–
Only perform the tasks on solid, level ground with suffi-
cient soil strength
–
Observe the permissible ground pressure.
–
Position the machine on level ground with sufficient load-
bearing capacity and stabilize the machine.
–
Use suitable outrigger pads.
The machine may suffer damage if positioned or used on
unsuitable ground with insufficient soil strength.
The machine exerts a maximum pressure on the ground
depending on the width of the crawler tracks.
To ensure safe operation, the permissible ground pressure must be
at least equal to the maximum pressure exerted by the machine.
