Operating manual
Working with the machine
– Familiarise yourself with the emergency exit through the front window. – The windshield is used as an emergency exit and may not become blocked by placing any items against it, e.g. a front guard! If a front guard is necessary, it should be arranged so that an emergency exit through the front window is still possible . – Put on the safety belt immediately on entering the cab and close the cab door before starting the engine. – The cab elevation is designated for a maximum 160 kg . – It is forbidden to carry passengers on the outside of the cab. – Weekly check the emergency lowering function via the both shut-off valves inside the cab. – Weekly check that the cut off for swing movements and for cab lowering movements are functioning and that they react promptly. – Familiarise yourself with the cab's movements using the control lever before operating the cab elevation . – Only adjust the cab when the machine is stationary. – Presence of a third person in the danger zone of the excavator is not to be tolerated during the adjustment procedure of the cab. – Never drive the cab underneath a load in the clamshell or the lifting hook. It can be hazardous if the load drops from the clamshell or the lifting hook. – Please be fully aware of the danger that could occur during operation of the cab elevation and the lift frame, e.g. collision with parts of the undercarriage or with the load in the clamshell or the lifting hook. – Always maintain visual contact with the undercarriage when lowering the cab. – Be aware of the location of electrical lines around the working area and maintain sufficient distance at all times between the cab, elevation or other machine parts and electrical overhead cables. – Familiarise yourself with the safety distances which must be maintained and do not undertake any jobs where the necessary distance from electrical overhead cables can not be maintained at any time. – Never use the cab elevation as a crane. – The cab elevation should never be used during thunderstorms. – Adhere to all safety guidelines listed under heading "Safe use of machines with tower elevation" before in this manual. – With travel movements, please ensure that: • the working attachment is load-free and retracted as far as possible , • the travel surface is even, stable and free of any obstacles. – Travel in the machine should fundamentally only be carried out with the cab retracted and in the upper position, thus. with the uppercarriage side element of the elevation fully raised and the cab side element fully lowered. – Travelling the machine with the cab in raised up position is not permitted if the travel routes are not even and free of any obstacles or with inclines or bankings which could affect the stability of the machine. – Hold the cab as near as possible to the excavator's swing centre in order to reduce vibrations and swings in the cab as much as possible. Raise the uppercarriage side element completely, and adjust the height with the cab side element. – In the event of an unbalanced position - via a main block valve that has jammed, or a burst hydraulic hose, release the control lever immediately. Then shut off the diesel engine to cut off the oil supply. The cab will remain in position via the linebreak protection valve. – The cab can then be lowered using two emergency lowering shut-off valves located in the cab.
