The fluid ejecting apparatus includes a linear absorption member that is provided movable and is extended along the nozzle row, and a traveling mechanism that causes the absorption member to move. The excavation device also has a chain-type transmission to draw in rotation, in a first operating condition, each of the milling wheels. Utilization of the system with a flashlight enables the individual to move to a safer location, find their way out of the area, or to help others without an emergency light station nearby.
