Action
If using the Turning tool:
Secure the turning tool chain block to the
lifting eye in the wrist.
Shorten the chain to make the lift horizontal.
Fit a roundsling between the overhead crane
hook and the lifting eye in the arm house.
Lift the arm system up, to be able to reach
the contact surfaces underneath the frame.
Wipe clean the contact surfaces from any
remaining contamination.
Before putting the complete arm system on
to the guide pins, make sure that the hole
pattern will match and that the guide pins will
enter the correct holes in the frame.
Remove the big o-ring that holds the attach-
ment screws in the temporary position and
let them drop down on the base.
Note
Make sure that none of the screws are miss-
ing or in the wrong position.
Lift the complete arm system and lower it
slowly down over the guide pins, until it is
possible to insert the attachment screws
manually.
CAUTION
Do not lower the arm system completely at
this stage! The attachment screws must be
fitted in two steps. If not, the complete arm
system will risk resting on the attachment
screws in the wrong position!
Fit the attachment screws manually as far as
possible. Lower the complete arm system
slowly in steps, until all attachment screws
no longer can reach the base, when the arm
system is lowered all the way down.
Make sure that the complete arm system is
lowered all the way down.
