The Bomag BW 900-2 may not function in reverse or forward if the travel lever is not in the correct position. Ensure the travel lever is moved out of the "0"-position and shifted to the desired travel direction. Additionally, check for any issues listed in the troubleshooting section, such as insufficient fuel supply, clogged fuel lines, or engine faults that could affect operation.
