Safety is vital for all repair work on the roller. Always observe the following points, 
plus those under Safety First in the instruction manual. 

 

 

All maintenance and repair work can only be performed when the machine is low-
ered to the ground or locked in transport position, tractor is braked, engine stopped 
and ignition key removed to prevent accidental start. 
 

 

Particular  attention  must  be  paid  to  safety  when  repairing  hydraulics.  Before 
commencing work, depressurise hydraulic system and support part being worked 
on. 
 

 

Always  ensure  hydraulic  system  is  bled  after  repairs  and  before  use  to  prevent 
mechanical breakdown and injury to person. 

 

Hydraulics 

 
Replacing extend cylinder for folding side sections 
Roller must be fully extended and standing on ground for repairs.

Depressurise  cylinders.  Check 
there is no pressure shown on the 
manometer  

2.

 

Disconnect hoses.  

3.

 

Remove split pins and pins. Cylin-
der will now be free. 

4.

 

Fit  new  or  repaired  cylinder. 
Check pin locks into place, secure 
pins with split pins. 

5.

 

Connect hoses. Check there is no 
danger  of  hoses  being  ripped  or 
crimped after fitting.
