2.8 ADVICE TO RENEW FLEXIBLE HOSES
Before disconnecting a hydraulic pipe, place
containers of suitable size underneath to prevent
oil spillage.
Plug all disconnected parts to prevent dust or
impurities from entering the circuit. They can cause
serious damage.
Before disconnecting the hydraulic pipe, check that
there is no residual pressure. In case, eliminate the
pressure operating the control levers with the engine
stopped.
In any case, disconnect the hydraulic pipe with
extreme caution and always wear suitable personal
protection equipment -e.g. goggles, gloves, facial
screen, etc.
Wrap up the end of the pipe to be disconnected with
some rags and slowly loosen the pipe connector so
that air comes out as slow as possible.
Before disconnecting or refitting a flexible hose,
carefully clean the area all around.

For an easier renewal of the hoses, whose run is not
clearly visible, proceed as follows:
- disconnect the hose to be replaced from both
sides
- tie a cord to one end of the hose
- remove the hose pulling the cord until it comes out
completely
- untie the cord and tie it to the new hose
- pull the cord from the other side to refit the hose
until reaching the connecting point to the line.
