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.

Danger! - Hydraulic hose lines are subject to ageing
Effect:
The characteristics of the lines change depending on pressure, heat load and the effect of UV
rays.
The date of manufacture appears on the hydraulic hoses. This way the age can be ascertained
quickly.
By law the hydraulic lines must be replaced after six years.
Use original spare parts when replacing hydraulic hoses!
