DANGER
When removing the axis-3 gearbox, let the axis-2 gearbox stay fitted! Only remove
the screws that either secure the axis-2 gearbox to the lower arm, or the screws
that secure the axis-3 gearbox to the parallel arm, depending on which gearbox
shall be removed.
Note
The 45 attachment screws are arranged in three areas with 15 screws in each
area. All attachment screws can not be reached with the robot in the same
position. This procedure describes how to reach the screws in the first area. Only
remove the screws in this area, at this point.
Action
DANGER
Never remove the screws on both axis-2
and axis-3 at the same time. One side must
always be attached when the gearbox on
the other side is removed. If not, there is a
potential risk that a severe accident will
happen.
