socket forwards (mobile element – Fig. 9) or press the SAFETY BALL into the ball chamber
and close the operating lever slowly.
3.5 Checking the stabiliser
The condition of the friction pads can be checked after connecting and activating the
stabiliser. (Fig. 7) If the wear display is within the green „OK" range, the friction pads are
either as new or su cient for driving operation.
If the display has reached the yellow range, the friction pads will have to be replaced.
Do not drive with the trailer if the display is within the red „STOP" range.
Fig. 7: Wear display
The following causes for this are possible: Friction pads worn out, coupling ball worn out,
there is no coupling ball in the ball chamber of the WS 3000/3500.
3.6 Anti-theft device
WS 3000 ball couplings can be fitted with anti-theft devices ROBSTOP WS 3000 and ROB-
STOP WS 3000/3500 PLUS (reinforced hardened version with special locking cylinders
and SCM-NL, SBSC-S and SoldSecure-GB certificates) through the provided side housing
openings both in a coupled and an uncoupled state.
4. Information for journeys and maintenance
4.1 Coupling ball on towing vehicle
The coupling ball of the trailer coupling must comply with required dimensions and be
undamaged, clean and free of grease.
In the case of dacromet-coated (matt-silver corrosion-protection coating) and painted
coupling balls, the coating must be removed completely using 200-240 abrasive paper
prior to being driven for the first time and then cleaned, e.g. with thinners or spirit,
so that it does not collect on and clog the surface of the friction pads. The surface of the
coupling ball must be „bright metal". (Fig. 8) A damaged or unclean coupling ball results
in increased wear to the friction pads and a greasy coupling ball reduces the stabilising
effect considerably.
4.2 Ball coupling
Fig. 8: „bright metal"
Keep the inside of the ball chamber close to friction elements clean and free of grease (Fig.
9). If the friction pads are dirty, they can be cleaned using abrasive paper 200-240. Follow
this by cleaning the surface with thinners or spirit. Oil all moving bearings and bolts slightly.
Regular maintenance and care increases the service life, function and safety of your WS
3000/WS 3500 ball coupling.
4.3 Replacing friction pads
The friction pads are very easy to change if worn. We can supply a replacement set contai-
ning 2 friction pads: order no.: 6205 – CLIP-BELAG SET WS 3000
4.4 Travelling noise
Noise may occur whilst travelling, though these do not have any significance for the func-
tion of the ball coupling.
Possible causes of noise can include:
1. Coupling ball of the towing vehicle dacromet-coated, galvanized or painted
2. Coupling ball of the towing vehicle dirty, rusty or damaged
3. Friction pads in the WS 3000 dirty for reasons as named in sections 1.- 3. or for other
forms of contamination
Remedy: as for section 4.1 / 4.2
Furthermore, noise can occur as a result of:
1. Tow bar/pipe running dry in the bushings of the ramp
Remedy: Lubricate the bushings at the grease nipples, also pull off bellow and grease
exposed tow bar.
2. Removable coupling balls on towing vehicle
Remedy: Regrease removable coupling ball on the locking mechanism (see operating in -
Fig. 9: Location of friction pads
struc tions for trailer coupling).
