12.9.4 Installation and removal of hydraulic hose lines
When installing and removing hydraulic hose lines, always observe
the following information:
• Only use original AMAZONE hydraulic hose lines.
• Ensure cleanliness.
• Always install the hydraulic hose lines to ensure the following in
all operational positions
ο There is no tension, apart from the hose's own weight.
ο There is no possibility of jolting on short lengths.
ο Outer mechanical influences on the hydraulic hose lines
are avoided.
Use appropriate arrangements and fixings to prevent abra-
sion of the hydraulic hose lines by components or from
rubbing against one another. If necessary, secure
hose lines using protective covers. Cover sharp-edged
components.
ο The approved bending radii may not be exceeded.
•
When connecting a hydraulic hose line to moving parts, the hose
length must be appropriate so that the smallest approved bend-
ing radius is not undershot over the whole area of movement
and/or the hydraulic hose line is not overtensioned.
• Fix the hydraulic hose lines at the specified fixing points. There,
avoid hose clips, which impair the natural movement and length
changes of the hose.
• The coating of hydraulic hose lines is not permitted.
