Maintenance
Checking hydraulic pressure lines
Specific safety instructions
Use caution when checking the hydraulic lines; Especially when searching for
leaks.
Hydraulic oil escaping under high pressure can penetrate the skin and cause
serious injury.
Risk of injury!
☞Always consult a doctor immediately, even if the wound seems insignificant
– otherwise serious infections could set in!
☞Always observe the following instructions:
• Retighten leaking screw connections 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 screw con-
nections. Have damaged parts replaced 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 service centers 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 the vehicle 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 Tl. 5.
The date of manufacture (month or quarter and year) is indicated on the flexible line.
Example:
The indication “1 Q/07” means manufactured in the 1st quarter of 2007.
