8.10.1
Depressurise hydraulic system
WARNING
Risk of accidental contact with hydraulic oil due to hydraulic oil
squirting out under high pressure and entering the body, in
particular in case of hydraulic systems with membrane
pressure accumulator!
•
Working on the hydraulic system with the system under
operating pressure is not allowed.
•
Depressurise the hydraulic system before carrying out work on
the hydraulic system.
•
Relieve the respective hydraulic cylinder via the corresponding operating element with the
hydraulic oil supply switched off.
8.10.2
Marking of hydraulic hose pipes
The marking on the fitting provides the following
information:
(1)
Identification of the hydraulic hose pipe
manufacturer (A1HF)
(2)
Date of manufacture of the hydraulic hose
pipe (16/07 = year / month = July 2016)
(period of use expires in July 2022)
(3)
Maximum admissible operating pressure
(210 bar)

Inspection criteria for hydraulic hose pipes
Immediately have hydraulic hose pipes replaced by an authorised
workshop as soon as you detect any of the following defects:
•
Damaged outer layer down to the liner (e.g. due to chafing
points, cuts, cracks).
•
Embrittled outer layer (visible by cracking of hose material).
•
Unnatural deformations of the hydraulic hose pipe in
depressurised as well as in pressurised state or when bent
(e.g. separation of layers, blistering, pinches, kinks).
•
Leaks.
•
Damaged, deformed or leaking fitting.
•
Hose slipping out of the fitting.
•
Corroded fitting which may affect the function and the strength.
•
Improperly laid hydraulic hose pipes, e.g. ignored bending radii,
laying over sharp edges.
•
The hydraulic hose pipe is older than 6 years.
