12.6 Workshop work
WARNING
The work described in the Repairs section may only be performed by
a specialist workshop.
12.6.1 Checking the hydraulic hose lines
Adhere to the inspection intervals,
see section "Maintenance schedule", page 191.
Check the hydraulic hose lines and fix any defects (specialist workshop):

Damage to the outer layer up to the ply (e.g. scouring points, cuts, cracks).

Brittleness of the outer layer (crack formation of the hose material).

Deformations which do not match the natural shape of the hose or the hose line. Both in a de-
pressurized and pressurised state or when bent (e.g. layer separation, bubble formation, pinching,
bends).

Leak points. Tighten the screwed connections if necessary.

Damage or deformation of the hose assembly (sealing function restricted); minor surface damage
is not a reason for replacement.

Movement of the hose out of the valve chest.

Corrosion of valve chest, reducing the function and strength rating.

Installation requirements not complied with.

Life span of 6 years has been exceeded.
The date of manufacture of the hydraulic hose line on the valve chest plus six years is decisive. If
the date of manufacture on the assembly is "2020", then the hose should not be used after Feb-
ruary 2026. For more information, see section "Date of manufacture of the hydraulic hose line",
page 197.
