Action
Lift the lower and upper arm.
Make sure:
• not to stretch any of the cables
• that the arm package is level when
lifted.
Align the lower arm with the gearbox in
height. Match the upper edge of the gear-
box with the corresponding edge inside the
lower arm cavity.
Tip
This operation is best performed by two
persons working together.
Rotate the gear to match the hole pattern
in the lower arm, using the rotation tool.
Note
Some of the screw holes in the gear are
unused.
Slide the lower arm onto the guide pins,
when the hole pattern is matched and in
the correct position for all screws.
Slide the lower arm on to the guide pins.
Use caution and move the arms into posi-
tion at the axis-2 gearbox on the guide pins.
Rotate the axis-2 gearbox until the hole
pattern is matching the holes in the lower
arm.
Fit one attachment screw in one of the up-
per holes using it for security and lower the
lifting accessory a little.
