2 Transportation and Handling 2. Transportation and Handing 2.1 Handling of the Carton Each robot is packed with a controller prior to shipment. When transporting the carton containing the robot and controller, observe the following items and be careful not to drop the carton or apply impact due to forcible contact: x If the carton is heavy, one operator should not attempt to carry it alone. x Place the carton on a level surface if it is to be left there for a while. x Do not climb upon the carton.
2.3 Handling of Individual Components The robot and controller are supplied as a set. Your robot cannot be used with the controller supplied with another robot. When handling multiple robots, be careful not to lose their correct pairings with the controllers. 2.4 2. Transportation and Handing The robot will not stand on its own after being unloaded from the carton pallet. Hold it by hand, or place a cushioning material on the floor and place the robot on its side upon the cushion.
2.5 Transporting the Robot 2. Transportation and Handing When transporting the robot, affix the arms using the supplied arm fixing plate. Additionally, wrap the cables around the base and secure them with gummed tape or other means. Use a dolly, forklift, crane, or other appropriate equipment for transportation. When transporting the robot, move it slowly so that it maintains its balance. Also, safeguard the robot against vibration or impact.
3 Installation Environment and Storage Environment 3.1 Installation Environment Install the robot in an environment that satisfies the following conditions: Generally, the robot must be installed where the operator need not wear protective gear in order to work.
