Note
Make sure all hooks and attachments stay
in the correct position while lifting the arm
system and that the lifting accessory does
not wear against sharp edges.
Lift the complete arm system carefully and
secure it in a safe area.
Note
Continue lifting even if the arm system turns
out to be unbalanced despite earlier adjust-
ments! The risk of damaging the interface is
bigger if the load is lowered unbalanced!
