Installation and removal of hydraulic hose lines
Use
•
only genuine AMAZONE replacement hoses. These hoses stand
up to chemical, mechanical and thermal loads.
•
hose clips made from V2A for fitting hoses, as a rule.
When installing and removing hydraulic hose lines, always observe
the following information:
•
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 fixing to prevent any
scouring of the hoses on components or on each other. If
necessary, secure hydraulic hose lines using protective co-
vers. 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.
10.7.5
Mounting hose fittings with O-rings and sleeve nuts
1. First, tighten the sleeve nut manually.
2. Then, use the spanner to tighten the sleeve nut at least ¼ to a
maximum of ½ turn.
You must not tighten screw unions with O-rings as tight as those with
compression rings.
If you tighten the sleeve nut tighter than specified, the cone-shaped
screw union may break (in particular at the welded pin on the hydrau-
lic cylinder).
