15 Maintenance - hydraulic system
WARNING!
Risk of injury as a result of incorrect handling of liquids under high pressure.
Effect: Escaping high-pressure liquids can penetrate the skin and cause serious injury.
Repair work on the hydraulic system may only be performed by authorised KRONE
professional workshops.
• Depressurise the system before disconnecting lines.
• When searching for leaks, use suitable aids and wear protective goggles.
• High-pressure liquid that is escaping from a small opening is virtually invisible. Therefore,
you should use a piece of cardboard or something similar when searching for leaks. Protect
your hands and body.
• If liquid penetrates the skin, consult a doctor immediately. The liquid must be removed from
the body as quickly as possible. Danger of infection! Physicians who are not familiar with
this area must consult appropriate information from a competent medical source.
• Check hydraulic hoses regularly and replace if there are any signs of damage or ageing!
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.
WARNING! – Hydraulic hose lines are subject to ageing
Effect: Danger to life or serious injuries
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!
