Box rotator model 

Problem 

Solution 

 

 

 

All models.

 

The box rotator is not in a horizontal position if 

the piston rod of the cylinder is fully retracted. 

Loosen the two lower bolts M30 on the 

piston rod of the rotating cylinder. That 

allows the fork carrier to be straightened. 

After straightening, firmly secure the two 

lower bolts M30. 

 

All models. 

There is some play in the bearing (tapered roller 

bearing) on the shaft of the fork positioner. 

Loosen the lock nuts of the socket set 

bolts; fasten the socket set bolts by hand 

in the locking plate and turn one quarter 

back. Proceed with tightening the lock 

nuts.
