Operating instructions 10/2017
Marking lines with assigned letters "W" to "Z" have been cast in raised relief on the coupling housing to
assist filling the coupling and checking the filling level. These can be marked on the coupling, and/or further
markings can be added when the coupling is first filled with the correct filling quantity.
When filling and/or checking the filling level, turn the mark with the required filling quantity (in case of
intermediate values the corresponding intermediate position) to the top position (12 o’clock).
In case of filling through the filling plug (153) the coupling is filled with the required quantity, when the filling
level has reached the lip of the hole for the screw plug (163).
When changing the fluid take care that the old fluid has been drained completely. Draining the fluid is
possible by way of the openings in the screw plug (163). Drain the residual fluid off the prechamber
additionally by way of the opening in the screw plug (173) in figure 19 or figure 20 in section 11.
•
Check the coupling for leaktightness during a short test run.
Testing the leaktightness may be done by holding a clean piece of paper parallel to the turning axis and
close to the rotating surface envelope of the coupling.
Any operating fluid spurting out will be visible on the paper.
WARNING
Risk of serious injury through escaping operating fluid
Risk of serious injury through incorrectly tightened screw plugs.
After topping up the tightening torques specified in the maunal must be adhered to. Perform a test run
(with protective covering) with leaktightness test.
NOTICE
Material damage
Damage to the coupling possible.
FLUDEX couplings must not lose any operating fluid, as this loss may result in a rise in slip and coupling
temperature and ultimately to a fusing of the fusible safety plug (103).
•
Finally attach the coupling safeguard to prevent any accidental contact.
Faults in the drive (e.g. locking of the output side) may result in the coupling overheating. If the fusing
temperature of the fusible safety plug is reached, the insert will melt and the hot operating fluid escape.
The coupling protection must therefore be so designed as to also guarantee protection against operating
fluid spurting out without appreciably impairing the ventilation of the coupling. The fusible safety
plugs (103) and the filling plugs (153) should always be accessible.
