Make sure all hooks and attachments stay
in the correct position while lifting the arm
system and that the lifting accessory does
not wear against sharp edges.
Lift the complete arm system and move it at
very low speed to the mounting site, making
sure it does not tip!
Note
The refitting must be made completely level!
Make sure the roundslings are adjusted prior
to refitting the arm system.

Fit two guide pins in opposite holes in the
frame.
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 178.
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.

ance from the guide pins previously fitted to
the axis 1 gearbox.
