WEAR INDICATOR
If the handle reaches the back of the cutaway portion of
the housing, when the coupling head is engaged (Fig 36)
there will be play between the towball and coupling head.
Automatic re-adjustment is no longer possible and the
assembly will need inspecting.
CAUTION
Under these circumstances, the coupling head can become
detached from the towball and the caravan/ trailer can
breakaway from the tow vehicle. The coupling head and
towball must therefore be checked IMMEDIATELY before
future use. Any faulty parts must be changed IMMEDIATELY.
All maintenance work should be carried out by AL-KO
Approved Workshops.
