How heavy is the MF1538C and how should it be moved safely?

The host machine weighs a maximum of 41 kg including toner cartridges. It is recommended to lift it with 2 or more people, keeping the machine level during operation. When moving after unpacking, place a plate on areas with steps to prevent the casters from hitting those steps, as hitting a step may deform the casters or base plate. (Page 8)
