E-Ceiling Function
The e-ceiling function limits the operation of the boom, stick
and bucket – except for the swing when the height limit has been
set in advance. A height limit is set using the LCD monitor in the
cab and must be reset for each bucket. As the bucket is about to
exceed that height, the e-ceiling function starts and the bucket’s
vertical movement is brought to a halt.
Cab Avoidance Function
Once the bucket dimensions have been programmed into the
machine, cab avoidance will automatically stop the front linkage
and bucket to prevent interference with the cab.
