EXTRAORDINARY MAINTENANCE

08-Sostituzione dei tubi flessibili

8.1  Pipe replacement 

Any intervention or maintenance on the hydraulic system has to be carried out by 

specifically instructed personnel.

WARNING

 

►

Before working on the hydraulic system, release all residual pressure, working with the engine off and using all 

the control levers. 

 

►

Pay particular attention to cleanliness: dust, chips or other material can cause an irreparable damage to the 

hydraulic components. 

 

►

Replace any damaged pipes with original spare parts. When fastening be careful not to twist them and bear in 

mind their complete range of movement.

 

►

Do not spill any oil when replacing pipes. Collect the oil in containers and deliver it to the special oil collection 

centres. 

Check the state of wear of the hydraulic pipes every day. Replace them in the case of 

abrasions or cracks.

WARNING

Change the hydraulic pipes at least every 6 years.

WARNING

Remember to open the oil suction cocks after replacing the hydraulic pipes. The pump 

only needs to rotate “dry” for a few seconds to be irremediably ruined.

CAUTION

Periodically check the state of the filters and the level of hydraulic oil in the tank in order 

to avoid contamination, overheating or other damage to the hydraulic system.

CAUTION
