Avoid Undercutting; Avoid Tipping - Hitachi Zaxis 33U-5A Operator's Manual

Avoid Undercutting

 In order to retreat from the edge of an excavation if the
footing should collapse, always position the undercarriage
perpendicular to the edge of the excavation with the travel
motors at the rear.
 If the footing starts to collapse and if retreat is not
possible, do not panic. Often, the machine can be secured
by lowering the front attachment, in such cases.
