All lifting equipment used must be sized
accordingly!
12. Lift the arm system carefully and secure it
in a safe area.
Always move the robot at very low speeds,
making sure it does not tip.
Continue lifting even if the arm system turns

in the correct position while lifting the arm
system and that the lifting device does not
wear against sharp edges.
