Action
Unfasten the arm system from
the base by unscrewing its 16
attachment screws.
Fit two guide pins in two oppos-
ite screw holes.
CAUTION
The complete arm system
weighs 1250 kg! All lifting
equipment used must be sized
accordingly!
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 out to be unbal-
anced despite earlier adjust-
ments! The risk of damaging the
interfaces is bigger if the load is
lowered unbalanced!
