Installing and removing hydraulic hose lines
When installing and removing hydraulic hose lines, it is imperative that you observe the
following instructions:
Use only hydraulic hose lines supplied by the manufacturer.
Pay attention to cleanliness.
Install hydraulic hose lines in such a way that, in all operating conditions:
o
there is no tensile stress except that caused by the hoses' own weight,
o
there is no stress from compression on shorter hose lines,
o
there is no mechanical impact on hydraulic hose lines.
Prevent hydraulic hose lines from rubbing against components or against one
another by arranging and fastening them properly. Protect hydraulic hose lines
with protective sleeves if necessary. Cover sharp-edged components.
o
the bending radii are not below the permissible parameters.
You need to select the size of the hydraulic hose line used on moving parts in such a
way that:
o
the bending radius is not below the smallest permissible bending radius in the
entire area of movement,
o
the tensile load on the hydraulic hose line is not outside the permissible
parameters.
Fasten the hydraulic hose lines at the designated attachment points. Avoid any
additional hose brackets which impair the natural movement and length adjustment of
the hydraulic hose lines.
It is prohibited to refinish hydraulic hose lines.
