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 a Wacker Neuson service center.
► 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 screwed 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 screw
connections, but have damaged parts replaced.
• Wear protective equipment.
• Never search for leaks with your bare hands, but wear protective
gloves.
