REPLACEMENT OF OLEODYNAMIC PIPES
When replacing pipes, make sure to operate in compliance with the safety measures to be taken for
maintenance interventions. After closing the valves of the hydraulic system, make sure to have no
pressure inside the pipes and unscrew the connections of the damaged pipe, bewaring of possible oil
leaks. Replace the damaged pipe with an original spare part, also checking the wear condition of the
connecting parts. Tighten carefully the pipe’s connections, in order to prevent the threads from
getting damaged, then check the pipes and make sure they are assembled tight.
