Refit the hoses. 

-

 

After fitting, ensure that there is no risk of tearing or clamping of the the hoses. 

7.

 

Before using the machine again, the replaced cylinder(s) must be vented by moving them 
from outer position to outer position. 

 

 

 

For cylinders with a manometer in the circuit, you must ensure that no pressure is 
displayed on the manometer before the replacement is carried out. 

 

 

After mounting, activate the replaced cylinder(s) until a small amount of movement 
can be felt in the cylinder(s). Activate the cylinder(s) in the opposite way until the 
cylinders are back in the starting position. Move the cylinders a few times in this way. 
Then move the cylinders until they reach the outer positions, in order to vent the 
system. 

 

 

 

There must never be anyone present within the machines operating radius.
