Maintenance
Checking hydraulic pressure lines
Specific safety instructions
Danger!
Caution when checking hydraulic lines, especially when searching for leaks.
Hydraulic oil escaping under high pressure can penetrate the skin and cause
serious injury.
Injury hazard!
☞
Always consult a doctor immediately, even if the wound seems insignificant
– otherwise serious infections could set in!
☞
Always observe the following instructions:
• Retighten leaking threaded fittings and hose connections only when the
system is not under pressure. In other words, release the pressure
before working on pressurized lines!
• Never weld or solder damaged or leaking pressure lines and threaded
fittings. Replace damaged parts with new ones!
• Never search for leaks with your bare hands, but wear protective gloves!
• Use paper or wood to check for minor leaks. Never use an unprotected
light or open flame!
• Have damaged flexible lines replaced by a Wacker Neuson service
center only!
• Leaks and damaged pressure lines must be immediately repaired or replaced by an
authorized service center or after-sales personnel!
This not only increases the operating safety of your machine but also helps to protect
the environment!
• Replace hydraulic hoses every 6 years from the date of manufacture, even if they do
not seem to be damaged.
In this respect, we recommend that you observe all the relevant safety regulations for
hydraulic lines, as well as the safety regulations regarding accident prevention and
occupational health and safety in your country. Also observe DIN 20066, part 5.
The date of manufacture (month or quarter and year) is indicated on the flexible line.
Example:
