replaced by an authorised service centre.

manufacture, even if they do not seem to be damaged.
• Do not operate the machine with leaking or damaged hydraulic system
components.
• Use a piece of cardboard to diagnose the source of hydraulic leaks .
• Retighten leaking threaded fittings and hose connections only when
the system is not under pressure. Release the pressure before working
on pressurized lines.
• Never weld or solder damaged or leaking pressure lines and threaded
fittings, but have damaged parts replaced.
• Wear protective equipment.
• Do not search for leaks with your bare hands. Wear protective gloves
and search for hydraulic leaks with a piece of cardboard.
