7. Look through the empty mounting hole of
motor 1 to assist in aligning the assembly
during refitting of the arm system.
Lower the arm system with guidance from
the guide pins previously fitted to the
gearbox axis 1. Fit the guide pins in the cor-
responding holes in the frame as shown in
the figure to the right.
NOTE!
The refitting must be made completely level!
Make sure the lifting device is adjusted prior
to refitting of arm system.
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.
