Action
Remove two attachment screws (M12) in
opposite holes and replace them with guide
pins.
Note
Make sure that it is the screws that hold
the lower arm to the axis-3 gearbox that
are removed!
Tip
Lubricate the guide pins with some grease
to make the upper arm slide better.
Leave one of the remaining attachment
screws fitted, remove the other screws.
Action
Note
Make sure the lift is done completely
leveled! In case of necessary adjustments,
use the shortening loops on the lifting ac-
cessory (chain), and make sure to place
the chain the right way through the loops.
