General safety information for the hydraulic system
The hydraulic system is not approved for the use of BIO oils.
Only trained personnel are permitted to work on the hydraulic system!
High-pressure fluids which leak under pressure can penetrate the skin causing serious injury.
If you suspect that a pressure system may be damaged, shut down and secure the machine immediately and then
contact a qualified specialist workshop.
Never attempt to trace the source of leaks with your bare hands. Even just a pin hole can cause serious personal
injuries.
Use suitable materials when searching for leaks. (for example, a piece of cardboard)
Keep your body and face well away from leaks.
If a fluid penetrates the skin, it must be removed immediately by a doctor who is familiar with such injuries. Otherwise
serious infections may result.
Doctors unfamiliar with this type of injury should reference a knowledgeable medical source.
Prior to recommissioning, check the leak-tightness of the hydraulic system!
According to the manufacturer's specifications, the replacement period for hydraulic lines is 6 years.
