Maintenance and repair
Observe the instructions in section 3, "Safety instructions"!
All work on the coupling must be carried out only when it is at a standstill.
The drive unit must be secured against being switched on accidentally (e.g. by locking
the key switch or removing the fuses from the power supply). A notice should be
attached to the ON switch stating clearly that work is in progress.
Risk of burns after switching off.
Allow the FLUDEX coupling to cool down sufficiently before beginning work.
10.1
Changing the operating fluid
Never change the operating fluid immediately after operation.
There is a risk of scalding.
Allow the coupling and the operating fluid to cool down.
The operating fluid must be changed in accordance with the specifications in table 9.
When changing the operating fluid, care must be taken that the old operating fluid is completely drained
off. This can be done on size 222 through the holes in the fusible safety plugs (103) and on sizes 297 to 590
through the holes in the screw plugs (163).
Observe the environmental requirements in force.
