painepesurilla, täytyy vetopää irrottaa ja laittaa tulppa asennusputkeen. (Vetopäätä ei saa pestä painepesurilla)20 Towing hitch Without electrical set Manufacturer: WESTFALIA-AUTOMOTIVE GmbH Westfalia order no.: 313 174 Approval no. as per Guideline 94/20/EC: e13 00-0834 Class: A50-X Model: 313 164 Technical data: Maximum D-value: 7,4 kN Maximum nose weight: 75 kg Area of application: Vehicle manufacturer: Mercedes Benz Model: Vaneo Model designation: NCV1 General information: The vehicle manufacturer’s specifications regarding trailer load and nose weight are decisive for driving, and the values specified for the towing hitch must not be exceeded. The towing hitch serves for towing trailers fitted with ball couplings and for use with load carriers approved for attachment to the towing hitch. Any use other than that specified is prohibited. Driving with a trailer must be adapted to the road conditions. The vehicle’s handling is affected when a trailer is being towed. Follow the vehicle manufacturer’s instructions. If vehicles are fitted with a Parking Distance Control (PDC) system malfunctioning of the system can occur after tow bar installation since the parts (ball bar, ball coupling) could be located in the detection area of the sensors. In this case, the detection area should be readjusted or the PDC deactivated. Malfunctioning is not expected when using tow bars with detachable or pivoted ball bars if the ball bar is removed from its operating position. The fixing points specified as standard must be observed. National guidelines concerning official approval of auxiliaries must be observed. These installation and operating instructions must be enclosed with the vehicle papers. Installation instructions: The towing hitch is a safety component and must only be installed by qualified personnel. Any alteration or conversion to the towing hitch is prohibited, and would lead to cancellation of design certification. Remove insulating compound and underseal from vehicle (if present) in the area of the mating surfaces of the towing hitch. Seal any bare bodywork and bores with anti-corrosive paint. Operating instructions: Again tighten all securing bolts of the towing hitch after approx. 1000 trailer km, observing specified tightening torques. The towing hitch must be kept clean and greased. However, if a stabilisation device, e.g. Westfalia “SSK”, is used, the towing hitch must be free from grease. Follow the instructions in the relevant operating instructions. As soon as the towing hitch diameter is 49.0 mm or less at any point, it must no longer be used for safety reasons. After the towing hitch is fitted, the empty weight of the vehicle increases by 16,6 kg. Subject to alteration. GB21

Operating instructions for detachable ball rod Important: Each time before towing a trailer, check that the ball rod is properly locked (see A. 3 be- low)! Do not release unless the trailer is hitched up! When driver without a trailer, the ball rod must be taken off and the plug ALWAYS inserted in the mounting tube! A. INSTALLATION

1. Remove the plug from the

mounting tube. When the ball rod is taken out of the boot it is normally in the "pretensioned state". You can recognise this from the fact that the release lever (see sketch) is resting against the ball rod. There is a gap of about 6 mm between handwheel and ball rod (see sketch) and the "red" marking of the handwheel is in the "green" area of the ball rod. Please note that the ball rod can be inserted only in this state! Should, for whatever reason, the locking mechanism of the ball rod have been released before installation - you can recognise this from the fact that there is a gap of about 5 mm between release lever and ball rod (see sketch), the "green" marking of the handwheel is aligned with the "green" area of the ball rod and the handwheel (see sketch) is resting against the ball rod - the release mechanism has to be pretensioned as follows: Insert the key, open the lock and then pull out the handwheel to the side and turn it in the direction of the arrow as far as the stop. The release lever will then engage and, after the handwheel is released, the locking mechanism remains in the pretensioned position.

2. To install the ball rod, insert it

into the mounting tube from below and push it up.

• The locking operation is performed automatically in this case.

• Do not hold your hands in the area of the handwheel.

• Close the lock and withdraw the key.

• Press the cap onto the lock.

3. For safety reasons:

Always check whether the ball rod is properly locked and secured. You can recognise this from the following characteris- tics:

• "Green" marking of the handwheel is aligned with the "green" area of the ball rod.

• Handwheel is resting against ball rod (no gap).

• Lock closed and key with- drawn (handwheel cannot be pulled out).

• Ball rod must be fully inserted in the mounting tube and be tight (check by shaking). If the check of all 4 characteris- tics is not satisfactory, the installation procedure should be repeated. Even if only one of the character- istics is not met, the towing device must not be used. In this case, contact the manu- facturer. B. REMOVAL

1. Pull the cap off the lock and

press cap onto the handle of the key. Open lock with the key (key cannot be withdrawn when lock is open!)

2. • Hold ball rod tight, pull out

handwheel at the side and turn it against the force of the spring in the direction of the arrow as far as the stop.

• Remove ball rod downward out of the mounting tube.

• The handwheel can then be released; it then automatically engages in the tensioned position.

• Please also pay attention to the symbols on the handwheel and on the enclosed sketch "Detachable ball rod".

3. Stow the ball rod in the boot in a

safe place and protected against dirt. As already mentioned, the key cannot be withdrawn in the tensioned position. Insert plug into the mounting tube!

C. IMPORTANT POINTS TO

NOTE! The ball rod can be easily installed and removed with the normal force of your hands. Please never use any sort of aids or tools etc. as this might result in damage to the mecha- nism.22

Affix the enclosed information plate to the car close to the mounting tube or on the inside of the boot at a clearly visible point.

D. MAINTENANCE INSTRUCTIONS

1. The ball rod and the mounting

tube must always be kept clean to ensure proper operation of the coupling ball with bracket.

2. Ensure regular care of the

mechnical parts. Grease or oil the bearing points, friction surfaces and balls with resin-free grease or oil. Treat lock only with graphite.

3. If the detachable ball rod is not

used for a lengthy period, the locking mechanism should always be relieved of stress (locked position) in order to avoid excessive stress on the spring elements. Push the release lever forward into the locked position.

4. The ball rod must be taken off
