6. Dismantling the equipment / deactivation following operation
A visual inspection must be carried out after every use, but at least once a year. Every
three years or if there is any doubt regarding the safety or reliability of the equipment, a
functional test must also be performed. (Please also observe the relevant valid national and
international regulations pertaining to service intervals of hydraulic equipment).
ATTENTION!
Clean off any dirt before checking the equipment!
WARNING / CAUTION / ATTENTION!
To perform maintenance and repairs, personal protection equipment appropriate
for the work is an absolute requirement.
WARNING / CAUTION / ATTENTION!
Before dismantling the rerailing equipment, please ensure that the moved load is
in a stable and fi rm position!
Procedure:
1. Retract all the hydraulic cylinders and traversing cylinders to just a few mm)* protrusion
(base position) when the work is complete. This relieves the hydraulic and mechanical
stress on the equipment.
2. Then switch the hydraulic unit off.
3. Switch the two levers on the control table of the manual pressure switch-off valves to the
0 position (turn clockwise up to the stop). In addition, switch all the other levers in both
directions (lift/lower). Operating pressure at the pressure gauge 0 bar/psi.
4. You can then dismantle the system in accordance with the instructions in Chapter "Con-
necting the hydraulic equipment" and the separate instructions for the rerailing equip-
ment involved.
For dust protection, the supplied dust caps must be refi tted.
NOTE:
Coupling of the devices is only possible, when the hoses are depressurized.
WARNING / CAUTION / ATTENTION!
Some quick-disconnect couplings have special functions.Therefore, you must
not unscrew them from the hoses or swap them over!
ATTENTION!
The operating pressure in the system must be dissipated before uncoupling
the hoses. When the rerailing work is complete you must release the operating
pressure in the installation/system.
