Specific safety instructions
Warning!
Pressurized hydraulic oil hazard. Hydraulic oil escaping under high pressure
can catch fire, damage property, penetrate the skin and cause severe burns
and injuries.
• Do not operate the machine with leaking or damaged hydraulic system
components.
• Use a piece of cardboard to diagnose the source of hydraulic leaks.
• Hydraulic oil can be hot and can cause serious burns if contact is made
with skin. If contact occurs with hot oil, seek immediate medical attention
and treatment for the burn.
• Wear safety glasses/goggles to avoid eye contact. If oil contacts the eye
flush immediately with clean water and seek emergency medical treat-
ment.
• Seek immediate medical attention if oil penetrates the skin. Oil can cause
serious infections.
• Retighten leaking threaded fittings and hose connections only when the
system is not under pressure; i.e. release the pressure before working on
pressurized lines.
• Never weld or solder damaged or leaking pressure lines and threaded
connections. Replace damaged parts with new ones.
• Do not check for leaks with an incandescent light or open flame due to
explosive fire risk from vaporized oil mist.
• Leaks and damaged pressure lines must be immediately repaired or replaced by an
authorized Wacker Neuson service center.
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.
Observe all the relevant safety standards for hydraulic lines, as well as the safety regula-
tions regarding accident prevention and occupational health and safety in your country.
The article number is marked on the clamping section, and the date of manufacture is indi-
cated on the hose of each hose connection.
