Hydraulic pressure lines
Specific safety instructions
WARNING!
Use extra caution when checking hydraulic lines, especially when searching
for leaks. Hydraulic oil escaping under high pressure can penetrate the skin
and cause serious injuries . Always consult a doctor immediately, even if the
wound seems insignificant – otherwise serious infections could set in! 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!
☞
Always observe the following instructions:
• Retighten leaking fittings and hose connections only when the system is
not under pressure; i.e. relieve the pressure before working on pressu-
rized lines!
• Never weld or solder faulty or leaking pressure lines and connections.
Replace damage parts with new ones!
• When replacing hose lines, ensure that they are not twisted!
•
Leaks and damaged lines must be repaired or replaced as quickly as possible. This not
only increases the operating safety of the machine, but also helps to protect the
environment
