After  fitting,  the  harrow  hoist  is  actuated  until  the  cylinder  shows  a  slight 
travel. Reverse cylinder until it returns to start position. Move cylinder back-
wards and forwards several times. 

 

 

If cylinder is not bled correctly as described above, there is a risk that part of 
the  machine 

can  suddenly  move  much  quicker  than  normal,  and  before 

the  tractor  driver  can  prevent  it.

  This  is  because  air  (unlike  oil)  is  com-

pressible. A section can therefore swing out very quickly if air bleeding is not 
performed correctly. This represents a major risk of injury to personnel and of 
damage to the machine.   

 

 
Ensure no personnel are within the extension radius of the side sections. 

Replacing gaskets on the harrow hoist cylinder 

 

See the section "Replacing gaskets on tilt cylinder" 
 

Replacing cylinder for the front centre cross-kill axle (black) 

 

 

The  machine  is  folded  out  to  the 
working  position,  the  transport 
wheels  (A)  are  raised  so  that  the 
front  centre  cross-kill  roller  (B)  is 
just  resting  on  the  ground.  The  cyl-
inder is then depressurised (A).
