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 hexagon head bolt M14 x 90 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 - 10.9 / M16 - 8.8:
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 cou-
pling, attention 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 drawbar diameter. Use Ø 14x63 mm bolts for the WS 3500-D.
Please use the provided Ø 12x34 mm or Ø 12x49 mm bolts as to assist with this depen-
ding 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 connecting/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 diameters 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 positioning 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 draw-
bar closing the ball coupling automatically and the side securing plates (1) are positioned
parallel to the securing surfaces 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 places 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 si-
multaneously lift again (Fig. 6) so that the side securing plates (1) swing over the securing
surfaces and the operating lever can be moved into the open position. The trailer can now
be uncoupled from the towing vehicle with the help of a jockey wheel.
Important: The overrun device must be detensioned when uncoupling, i.e. the bellow
must be extended.
The trailer should be parked with the ball coupling closed if not being used for any greater
length of time. To do so, raise the open operating lever (Fig. 4), simultaneously pull the ball
