Checking hydraulic pressure lines
Specific safety instructions
Injury hazard when checking hydraulic pressure lines!
Can cause serious injury or death.
• Wear protective gloves and safety glasses.
• Search for hydraulic leaks with a piece of paper, for example.
• Always consult a doctor immediately, even if the wound seems insignifi-
cant. Hydraulic oil causes blood poisoning.
• Observe the following instructions:
• Retighten leaking screwed 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 (or have them replaced) with new ones
• Never use an unprotected light or open flame to check for minor leaks!
• Have damaged flexible lines replaced by a Wacker Neuson service
center only!
• Do not remove protective hoses from hydraulic hoses.
• 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 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.
The article number is marked on the clamping section, and the date of manufacture is indi-
cated on the hose of each hose connection.
