Danger! - Caution with leaking lines
Effect: Danger to life, injuries or damage to the machine.
• When searching for leaks, use suitable aids, always use suitable tools and wear
protective goggles to avoid the risk of injury!
• Escaping high-pressure fluids can penetrate the skin and cause serious injury. Therefore,
you must depressurise the system before disconnecting lines.
• Hydraulic oil escaping from a small opening can barely be seen. Because of this you
should use a piece of cardboard or something similar when searching for leaks. Protect
your hands and body.
• If any fluid penetrates the skin, it must be removed immediately by a doctor who is
familiar with this kind of injury; serious infections could otherwise result. Physicians who
are not familiar with this area should consult appropriate information from a competent
medical source.
• Check the hydraulic hose lines at regular intervals and replace them if damaged or worn!
The replacement lines must comply with the requirements of the device manufacturer.
• Ensure that all line connections are tight before the pressure in the system builds up
again.
• Repair work on the hydraulic system must only be performed by authorised KRONE
professional workshops.
