Fit two guide pins in the holes in the axis 1
gearbox, shown in the figure.
Tip
In order to make refitting easier it is recom-
mended to use two guide pins of different
lengths. Notice that longer guide pins than
140 mm will not be possible to remove after
refitting because of lack of space.

Dimension is specified in Required
equipment on page 174.
Note
Always use guide pins in pairs.
Look through the empty mounting hole of the
axis 1 motor to assist in aligning the as-
sembly during refitting of the complete arm
system.

CAUTION
This is a complex task to be performed
with utmost care in order to avoid injury
or damage!
Use a crank to turn the gearbox in order
to find the right position for the holes.
Lower the complete arm system with guid-
ance from the guide pins previously fitted to
the axis 1 gearbox.
Note
The refitting must be made completely level!
Make sure the roundslings are adjusted prior
to refitting the arm system.
