• Carry out a beaconing of the sector (maximum risk zone = machine height).
• Locate the hoses and their connections points to guarantee the good performance of the machine after intervention.
• Locate the hoses course to facilitate the reassembly.
To recover oil, use an oils container in order not to pollute the environment.
