COUPLING OF A SINGLE-AXLE 
TRAILER 
Coupling can be performed using the in-
ner hydraulic circuit lever (A) with posi-
tion regulation engaged. The hitch hook 
with the trailer pole eye is lifted hydrauli-
cally to the position where the supporting 
hooks click under pins of the hitch car-
rier. The lifting arms of the hydraulic de-
vice then shall be lowered to lock the 
supporting hooks onto the carrier pins; 
the telescopic pull rods shall not be un-
der any tension.
