A rollover protection structure for the cab provides protection in the event of the machine tipping over, and the rear window serves as an emergency exit on all versions of the excavator. The uppercarriage is accessed via a secured access platform and is fitted with non-slip studs. The generation 8 crawler excavators also have maintenance points that can be accessed from the ground. The engine oil, hydraulic oil, fuel and DEF levels can be monitored via the touchscreen.
