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 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 fold/extend cylinder for side sections (inner) 

Perform repairs with POWERROLL fully extended and resting on the ground in work-
ing or transport position. 
 

 

Fig. 18 

1.

 

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.
