Hydraulic hoses
Hydraulic hoses age without showing externally visible signs. In ac-
cordance with international regulations, the hydraulic hoses must be
replaced every 6 years.
The hydraulic hoses have codes both on the hose and on the swaging
which give the production date of the hydraulic hose.
The period of six years is calculated beginning on the production date
of the hydraulic hose.
Replacing hydraulic
hoses
All pressure must be released from the hoses. Only use hydraulic
hoses with the same specification. The hydraulic hoses within the
frame must only be replaced in a specialist workshop.
