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 injuries.
Danger of personal 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 screwed fittings and hose connections only when the
system is not under pressure; i.e. release the pressure before working
on pressurised lines.
• Never weld or solder damaged or leaking pressure lines and screw
connections. Replace damaged parts with new ones.
• Never search for leaks with your hands.
• Have damaged flexible lines replaced by authorised workshops only.
• Leaks and damaged pressure lines must be immediately repaired or replaced by an
authorised workshop or after-sales staff. 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 20 066.
The article number is marked on the clamping section, and the date of manufacture is
indicated on the hose of each hose connection.
