Replacing the roller in the front centre section 

 

Lifting gear with a minimum lifting capacity of 1000 kg must be available.  

 
 

Replacing the front centre roller 

 

 

1.

 

The  machine  is  extended  in-
to  the  working  position  and 
lowered  via  the  wheel  frame 
(A)  until  the  axle  (B)  just 
touches the ground. 

2.

 

 Loosen  and  remove  bolts 
(C)  

3.

 

Then  raise  the  machine  on 
the wheel frame (A) again. 

4.

 

The axle with cross-kill rings 
are  no  free  and  can  be 
moved  for  repair  with  the 
lifting gear. 

5.

 

Reverse  procedure  for  as-
sembly 

 

 

 

 

Do not activate hydraulics if persons are within machine extension radius.
