Changing the tilt cylinder 

 

Fig. 27 

The drum is unfolded and lowered onto the 
base  (working  position).  The  pressure  is 
removed from the tilt cylinders (A). 

 

 

 

1.

 

The hoses are disconnected from the cylinder. 

2.

 

The cylinder is supported. 

3.

 

The cotter pins in the rivets are disconnected while the rivets are un-
installed. 

4.

 

The cylinder can be uninstalled. 

5.

 

New or repaired cylinders can be installed. 

 

 

After mounting, the cylinders are activated until a small amount of movement can 
be felt in the cylinders. The cylinders are then activated in the opposite way until 
the cylinders are back in the starting position. The cylinders are moved a few times 
in this way, after which the cylinders are moved out in the outer positions a few 
times to air the system out. 

 

 

There must never be people within the machine's operating radius.
