Maintenance and service 10.
The hydraulic units are subject to very high mechanical loads. For this reason, visual
inspections and function tests must be carried out at regular time intervals. These inspections
and tests enable signs of wear to be identified in good time. Prompt replacement of wear
parts can then prevent damage to the equipment. Also check regularly that all fastening
screws are tightened securely (observe tightening torques where applicable).
You must observe all applicable national and international laws, rules, regulations and
standards relating to the maintenance intervals of rerailing equipment.
CAUTION!
Clean off any dirt before checking the equipment.
WARNING / DANGER / CAUTION!
In order to carry out maintenance and repair work, tools appropriate for the job
and personal protection equipment obligatory (including protective covers).
10.1 Recommended inspection intervals
Operating time per day Function test
up to 1 hour
1 x annually
up to 8 hours 1 x per quarter
up to 24 hours 1 x per month
In addition to these inspection intervals, a function test should be performed if the unit is
making suspicious noises or if there is reason to suspect that the unit has been damaged
internally.
If these noises or signs of possible damage arise more than once in a month, or if the
nominal pressure (75% of maximum pressure) is not achieved during the function test itself,
you must contact the LUKAS Customer Service department immediately. You will find the
relevant contact information in the “Troubleshooting” chapter.
