Figure 3-1 Schematic diagram of lifting and transportation

When transporting, be sure to install the fixing jig for transport!
When using other transportation methods without using cranes and forklifts, please
note that the robot arm and motor cannot be subjected to external forces!
After unpacking and installing, be sure to remove the transport fixture and rubber
pad!
Fixing fixtures will be needed for robot handling in the future, so please keep them
properly!
