10. Maintenance and cleaning:
With proper maintenance, simple operation and faultless function are guaranteed
for a long time.
10.1 Coupling ball
Diameter Ø50 mm on the towing vehicle
The coupling ball must be dimensionally accurate, clean and free of grease.
In the case of Dacromet-coated balls (matt silver anti-corrosion coating) and painted
coupling balls, the coating must be completely removed using sandpaper (200 – 240
grit) before towing for the first time and then cleaned with, for example, nitro
thinner or ethyl alcohol so that the coating does not build up on the surface of the
friction elements.
The surface of the coupling ball must be “bare metal”.
A damaged or unclean coupling ball surface leads to increased wear of the friction
elements, whilst a greased coupling ball greatly reduces the stabilising effect.
Nitro thinner or ethyl alcohol is suitable for cleaning, for example.
The coupling ball must be checked and measured regularly; the diameter must not
fall below 49 mm at the smallest point.
If necessary the coupling ball must be replaced
10.2 Coupling head
The inside of the ball chamber where the friction elements are located must be kept
clean and grease free at all times. In case of dirty friction linings, the surface can be
cleaned with sandpaper, 200 – 240 grit. Then clean the surface with benzine or
ethyl alcohol. All movable bearing points and bolts are to be lightly oiled. Regular
maintenance and care will increase the service life, function and safety of your
stabilising coupling head.
Also check that the movement of the indicator pin in the ball chamber of the
coupling head is unimpeded. The indicator pin must retract automatically when the
coupling is uncoupled. The green indicator section of the pin must then no longer be
visible.
Mobility of the safety indicator
When the ball is removed, the safety indicator (if available) must retract automatical-
ly so that only the red indicator (no ball in) is visible.
If this is not the case, the coupling head must be cleaned and lightly lubricated. If the
safety indicator (if available) does not work automatically after taking these measu-
res, then the coupling head must be replaced.
