Replacement andrepairs 

 

Safety is vital for 

all

 repair work on the roller. Always observe the following points, 

plus those under Safety First in the instruction manual. 

 

 

When replacing cylinders, always fill new cylinder with oil before pressurising sys-
tem.  We  recommend  fitting  cylinder  to  frame  first,  fill  with  oil,  before  completing 
fitting at top. 

 

 

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 com-
mencing work, depressurise hydraulic system and support part being worked on. 

 

 

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

 

Hydraulics 

Replacing extend cylinder for retracting side sections 

Roller must be fully extended and standing on ground for repairs.
