Checking the hydraulic system for leaks
Leaks and damaged pressure lines must be immediately repaired or
replaced by a Wacker Neuson service center. This not only increases the
operating safety of the machine but also helps to protect the environment.
► Leaks and damaged pressure lines must be immediately repaired or
replaced by an authorised service centre.
► Have hydraulic hoses replaced every 6 years from the date of
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.
