Action
Run a roundsling through the hole in the frame.
Connect the two roundslings with a shackle.
Turn on the power to the robot and jog axis-3
slowly until the roundsling is stretched (approxim-
ately +65°), to carry the weight of the lower arm
and frame.
WARNING
Without the roundsling the weight of the lower
arm and frame is applied to the axis-3 gear during
lifting, which risks to damage the gear.
