The friction pads (Fig. 14/Pos.
k l
, ) press against the coupling
ball to generate a damping torque
that prevents rocking.
Therefore, the friction pads are sub-
ject to wear. The friction pads have
a buffer, giving them a high wear
lifespan.
Maintenance and cleaning
Exchanging the friction pads
(lateral friction pads)
• Arrow on the pressure disc (Fig. 15/Pos.
reaches or surpasses the exchange mark on
the case (Fig. 15/Pos.
• Unhitch AKS 2004/AKS 3004.
• Use a screwdriver to remove the protective
caps (Fig. 16/Pos.
• Press used friction pads (Fig. 16/Pos.
inwards and remove (use a hammer and
punch).
• Insert new friction pads from below, placing
the bolt in the bush (Fig. 16/Pos.
press them all the way in. (Bolt will lock into
place; no tools required.) If adjusting washers
are provided (Fig. 16/Pos.
them together with the new friction pads.
Checking the shells for friction pads
• If you drive a lot of miles over a number of
years, the shells for the friction pads for AKS
2004/AKS 3004 will be subject to a certain
amount of mechanical wear. To enable the
user to check them regularly, a control display
showing wear has been integrated in the hand
j
grip (Fig. 17/Pos.
• Hitch the AKS 2004/AKS 3004 to the base
vehicle (do not activate the stabilizing device).
• If a green light is visible on the coupling grip
k
(Fig. 18/Pos. ), the AKS 2004/AKS 3004
is either new or the wear on the ball and the
AKS 2004/AKS 3004 is still within the permis-
sible limits.
• If you can only see a red light (Fig. 19/Pos.

), this could be caused by one of the fol-
lowing:
- AKS 2004/AKS 3004 is not worn out, but
coupling ball is worn out to the limit (diame-
ter of 49 or less).
- AKS 2004/AKS 3004 and coupling ball are
