Sicma TR80 - Check of Wear and Efficiency of Hydraulic Pipes

Maintenance
6.6.6 Check of wear and efficiency of hydraulic pipes
If the visual inspection reveals one or more of the anomalies listed below,
proceed to replace the damaged part, as per the procedure indicated in the
paragraph “6.6.7 Replacement of fittings and hydraulic pipes” pag. 118.
- Abnormalities on the external surface of the hydraulic pipes (cracks,
cuts, abrasions).
- Wear of the outer surface (appearance of cracks).
- Deformation not corresponding to the natural course of the pipe. The
check must be carried out starting with the unpressurized pipe and
proceeding up to the working pressure. When the pipe deforms, it is
necessary to observe the detachment of the plies and/or the presence
of bubbles, blowholes, breaking points, bottlenecks or twists.
- Hydraulic oil leaks or leakage.
- Damage or deformation to the hose connections (impairment of the
pressure seal), including the perfect seal of the metal fitting with the
flexible portion of the pipeline (sheathed hydraulic pipe).
- Corrosion of the fittings that could compromise the tightness or fixing
of the fitting.
DANGER
It is forbidden to use the machine if one or more of the above defects are
found.
Under regular use, the service life of a hose is 6 years (DIN 20066 standard).
The date of construction of the pipe, stamped on the outside of the casing,
according to the standards in force, is authoritative. This duration is in any
case indicative; if damage or anomalies are found in the hydraulic lines
during the inspections, they must be replaced immediately.
If there is no date stamped on the pipes or if it is not readable, the pipes must
be replaced no later than 6 years from the date of delivery of the machine.
