WARNING
High pressure hydraulic oil ejection hazard when checking
hydraulic pressure lines.
Can cause severe injury or death.
•
Always consult a doctor immediately, even if the wound seems insignificant.
Hydraulic oil causes blood poisoning.
•
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!
• Do not search for hydraulic leaks with your bare hands. Wear protective
gloves and search for hydraulic leaks with a piece of cardboard.
• 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 cen-
ter only!
• Leaks and damaged pressure lines must be immediately repaired or replaced by a
Wacker Neuson 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 occu-
pational health and safety in your country. Also observe DIN 20066, part 5.
