9.2 Preventive service
9.2.1 Care regulations
The exterior of the equipment is to be cleaned from time to time in order to protect it from
external corrosion. Oil is to be applied to the metallic surfaces.
9.2.2 Stress test
If there is any doubt regarding the safety or reliability of the equipment, a function and load
test must also be performed.
9.2.3 Replacing the hydraulic fluid
After approx. 200 deployments, but after three years at the latest, the hydraulic fluid in the
entire rerailing system must be replaced.
Due to the small amount of hydraulic fluid in the control desk, a fluid replacement does not
need to be carried out separately here. It is sufficient to flush it with the new hydraulic fluid
at the time of a fluid replacement in the entire system. All valves should be actuated in the
process (if necessary, connect the supply and return lines of each valve to each other to
flush them with the new fluid).
CAUTION!
During a hydraulic fluid replacement, always use a suitable receptacle to collect
escaping fluid and dispose of the collected fluid correctly.
CAUTION!
All of the hydraulic fluid in the system must be replaced if conditions of use
(ambient temperatures) vary considerably. When selecting the appropriate
hydraulic fluid, please observe the “Recommended hydraulic fluids” chapter.
REMARK:
Before you use couplings from a different company, you must contact LUKAS or
an authorised dealer.
CAUTION!
Since LUKAS rerailing devices are designed for top performance, only those
components in the spare parts lists of the relevant unit may be replaced.
Further components in the devices may only be replaced if:
- You have participated in appropriate LUKAS service training,
- You have the explicit permission of the LUKAS customer service (on request,
check for granting permission. Check is necessary in each individual case.)
