WS 3500-D ball couplings are suitable for the following connections and are to be connected as
follows:
WS 3500-D60-1414:
Drawbar diameter 60 mm with spacer plate 65/60, hexagon head bolt M14 x 110 for lengthways
connection (1+2) with self-locking nuts
WS 3500-D60-1616:
Drawbar diameter 60 mm with spacer plate 65/60, hexagon head bolt M16 x 110 for lengthways
connection (1+2) with self-locking nuts
WS 3500-D65-1414:
Drawbar diameter 65 mm, hexagon head bolt M14 x 110 for crossways connection (1) and hexa-
gon head bolt M14 x 80 for crossways connection (3) with self-locking nuts and stop (4)
The fastening material (1, 2, 3) is included; the stop (4) is not included with the product.
Torque for hexagon head bolts M12 / M14 / M16, 10.9:
WS 3000-D - 90 Nm
WS 3000-H/L/LB - 70 Nm
WS 3500-D - 90 Nm
Important: Self-locking nuts may only be used once.
Important: The WS 3000-D may not be connected using M12 bolts if the drawbar pipe of the WS
3000-D is provided with Ø 14 mm fastening holes. The WS 3000 can be fitted at works with holes
for fastening with M14 bolts.
2.2 If the WS 3000/3500 coupling is being used as replacement for another type of coupling, at-
tention must be paid in respect of the overrun device that the shock absorbers are correctly fitted
and that any spacers in the drawbar are correctly reinstalled. With the WS 3000-D, please use the
provided Ø 12x34 mm or Ø 12x49 mm bolts to assist with this depending on the size of the draw-
bar diameter. Use Ø 14x58 mm bolts for the WS 3500-D. Please use the provided Ø 12x34 mm or
Ø 12x49 mm bolts as to assist with this depending on the size of the drawbar diameter. Use bolts
to push through when removing the fastening screw (2) or (3) (Fig. 3) depending on the type of
shock absorber fastening, and insert in the drawbar for centering the shock absorber when con-
necting/dismantling the ball coupling. Remove the bolt again when inserting the new fastening
screw.
2.3 The enclosed bellow for the WS 3000-D can simply be pushed over the drawbar pipe prior to
assembly in the case of drawbar diameters of 40-50 mm. In the case of diameters of 60-70 mm,
the small connecting piece in front of the rubber lip will have to be removed, e.g. with a knife.
In the case of crossways screw connection, also cut out the lower marked hole, in the case of
lengthways screw connection cut out both side marked holes. The enclosed bellows for the WS
3500-D can simply be pushed over the drawbar pipe prior to assembly in the case of drawbar dia-
meters of 60 mm. In the case of diameters of 65 mm, the small connecting piece in front of the
rubber lip will have to be removed.
3. Operating instructions
3.1 Coupling
Please use the handles on the trailer and not the operating lever of the WS 3000/3500 when po-
sitioning the trailer. Place the open ball coupling on the vehicle's coupling ball (Fig. 4). The weight
of the supported load (plus possible additional pressure) results in the drawbar closing the ball
coupling automatically and the side securing plates (1) are positioned parallel to the securing sur-
faces on the housing (Fig. 4). The green pin in the control display (2) is visible if the coupling ball
is located in the coupling housing (Fig. 4).
3.2 Activating the stabiliser
Press the operating lever downwards from the closed position as far as it will go (Fig. 5). This pla-
ces tension on the spring assembly which applies pressure to the coupling ball via the friction
pads. The operating lever is now approximately parallel to the drawbar.
3.3 Deactivating the stabiliser
Pull the operating lever up slowly to deactivate the stabiliser (Fig. 6).
3.4 Uncoupling
Disconnect lighting plug and contact breaking cable. Pull the operating lever upwards slowly in
order to switch off the stabiliser (Fig. 6). Pull the operating lever back and simultaneously lift
again (Fig. 6) so that the side securing plates (1) swing over the securing surfaces and the opera-
