Rear carrier side viewMounting plate for the quick-release mechanism20 Scope of application The rear carrier system type ProfiTech is intended to transport game and can only be used in con- nection with a type approved tow ball with brackets (DIN 74058 / ISO 1302) suitable for mounting the rear carrier system and which is mounted on the motor vehicle. Some vehicle manufacturers also give approval to use rear carrier systems for the standard tow coup- ling mounted on the vehicle. For this purpose, the permissible loads and geometries are described in the operating instructions for the vehicles. These are decisive for the use of the rear carrier systems. If there is no approval to use rear carrier systems for the respective tow coupling, the suitability test must be conducted as described below. The suitability test was prepared based on § 30 of the Road Traffic Licencing Regulations (StVZO) – instructions on the application of rear mounted carrier sys- tems on passenger cars and caravans. Suitability test for the tow coupling The rear carrier system can be mounted onto a type approved tow coupling under the following con- ditions:

1. The ball and the tow bar must consist of one single piece.

2. The material of the tow bar must have a minimum quality of St 52-3 (tow bars are usually made

of an St 52-3 material).

3. The area between the ball and the fixing point cannot indicate any weakening. (welding point or

4. The permissible drawbar load on the tow coupling (refer to nameplate on the tow coupling) must

amount to at least 70 kg.

5. Calculation of the minimum D-value, which the tow coupling on the vehicle must have. The

permissible D-value of the tow coupling must be equal to or higher than the D-value calculated based on the table on page 21. To do so, the measurements K and L of the tow coupling must be determined (measuring the vertical height K and the horizontal length L as shown in Fig. 2 below).

Calculation of the minimum D-value, which your tow coupling must have: D-value in kN Compare the calculated D-value from the table with the information regarding the D-value on the na- meplate of the tow coupling (if you are unable to find the nameplate for the tow coupling, request the D-value and the permissible drawbar load from your authorised service centre, the car manufacturer or from the manufacturer of the tow coupling). Example: D-value according to nameplate: 10.5 kN permissible drawbar load: 70 kg vertical height K: 80 mm horizontal length L: 250 mm

1. Comparison permissible drawbar load has been met because there is a minimum drawbar load

2. Now, look at the D-value in the table at the interface 80 mm height/250 mm length, in this case

7.1. With it, the requirement is met; this D-value of the tow coupling is higher than the minimum D-value calculated from the table.

3. That results in the rear carrier being able to carry a payload of 59 kg (max. payload of the rear

carrier). Preparation and assembly of the rear carrier on the tow coupling Mount the quick coupling on the rear carrier basket using the enclosed mounting materials (4 bolts M10x25, 4x washers, 4 lock nuts). (please refer to page 8, Fig. 1). Then, mount the quick-release mechanism to the rear carrier basket using the enclosed mounting screws. Please make sure that all screwed connections are tightened appropriately (observe tighte- ning torque). Only use the enclosed lock nuts. All grease must be removed from the tow ball before placing and mounting the rear carrier on the tow coupling. Pull out the safety bolt (A) and rotate it 1/4 turn. Now, the lever can be flipped upwards. Both ball clamping jaws in the quick-release mechanism open. Place the rear carrier onto the tow ball and press the lever halfway down, so that the carrier can still be adjusted horizontally. If the rear carrier is aligned horizontally behind the car, press the hand lever all the way down and secure it using the safety bolt. Important: the contact pressure of the ball clamping jaws must be readjusted or readapted to every tow coupling, to achieve the required clamping stability. To do so, first loosen the counter nut (C), to then tighten the adjustment screw (B) with 32 Nm using a torque wrench. At the same time, the hand lever must be in the clamping position (pressed down). Then, retighten the counter nut. The contact pressure of the ball clamping jaws must be checked at regular intervals. This adjustment must be repeated for every vehicle/coupling change. If you do not have a torque wrench, have this adjustment work conducted in a workshop. You can protect the rear carrier against theft by inserting a padlock into the holes (D) intended for this purpose.

• Disconnecting the electrical connection.

• Pull out the safety bolt (A) and rotate it 1/4 turn (refer to Fig. 1).

• Flip the hand lever upwards. In the process, hold onto the basket firmly, so that it cannot flip downwards and damage the vehicle.

• Lift the basket with the quick coupling off the tow coupling in an upward direction. Pay attention not to damage your vehicle by means of fast, uncontrolled movements. General information Rear lighting installations and licence number. If the vehicle’s tail lights and/or licence plate number are partially or fully covered by the rear carrier or the load, the vehicle lighting and/or the licence plate number must be revised. The lighting optional at the time of the first registration of the vehicle does not need to be revised. Securing of loads The vehicle driver is responsible for the load being properly secured in accordance with the Road Traffic Regulations (StVO). Pay particular attention that the load does not extend farther than 40 cm beyond the outer edge of the light-emitting surface of the tail lights. Additional information On the side, the rear carrier cannot project beyond the end of the vehicle. The axle load distribution specified by the vehicle manufacturer is altered by the load placed on the rear of the vehicle. This alteration cannot lead to the permissible axle load being exceeded. The manner of driving must be adapted to the load condition and if necessary, changed vehicle hand- ling First registration of the vehicle Lighting as of 01/01/1987 installation prior to 01/01/1987 until 31/12/1990 ab 01.01.1991 Backup lights optional mandatory mandatory Fog tail lamp optional optional mandatory23 Model: Rear carrier for tow couplings, with quick release lever coupler, hinged, (item no. 20215) Please read these operating instructions carefully before use and keep them in a safe place for future reference.
