serious injuries.
Danger due to lines under high pressure –
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 screwed 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
fittings. Replace damaged parts 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 naked flame.
• Have damaged flexible lines replaced by authorized workshops only.
• Leaks and damaged pressure lines must be immediately repaired or replaced by an
authorized workshop.
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.
Environment!
Ensure environmentally compatible disposal.
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.
