MAINTENANCE OF THE FLEXIBLE HOSE
INSPECTION OF THE HOSE
•
Lay the flexible hoses on the floor and control if there are oil leaks and the hose surfaces are
integral without peeled sections showing metallic braid with broken wires.
•
the presence of little sections of wire braid can be tolerated only if the wires are not broken
and still braided.
•
Control the pressed bushing at the extremity of the hoses and discard immediately hoses
showing damaged end terminals with unnatural bending, squeezing, deformations, etc….
•
Check that the quick couplers are well dry, without oil leaks and that the knurled bushing on
the female quick coupler is intact and can slide freely during the connections. The male
coupler should be intact, without dents and deformations. If you try to force the connection of
a damaged male coupler, this will damage irremediably also the female.
•
If the flexible hoses and quick couplers show oil leaks, even if the couplers are well screwed
into the hose fittings, they should be immediately substituted with new parts.
•
Replace hoses that show squeezing, unnatural bending, deformations, swellings, etc…
If a flexible hose full of oil remains under the sun, the oil expansion due to the heat can
cause a pressure increase and prevent the connection of the quick couplers. To decrease
pressure, loosen one coupler, dripping some oil drops de-pressurizing the hose.
The flexible hose always remains full of oil that, depending on the hose length, can have a
relevant volume. If you change the hydraulic oil in the power pack it is recommended to
replace also the oil in the hoses. This will assure a full replacement and avoid the
contamination of the new oil.
