WARNING!
Risk of injury from incorrect handling of liquids under high pressure. Escaping high-
pressure liquids may 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 working on the hydraulic system, wear personal protective equipment (protective
goggles and protective gloves).
•
High-pressure liquid that is escaping from a small opening is virtually invisible. Therefore
use a piece of cardboard or something similar when searching for leaks.
•
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 the hydraulic hoses at regular intervals and replace them if damaged or worn! Only
original KRONE spare parts are permitted to be used as replacement lines as they
correspond to the technical requirements of the manufacturer.
•
Before the pressure in the system builds up again, ensure that all line connections are tight.

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!
