General safety instructions

Dear Customer, we are pleased that you have chosen a UEBLER bike carrier. The procedures and safety instructions listed in this installation and operating manual must be strictly followed. We assume no liability for any damage resulting from failure to comply with these instructions.

Caution

Before you begin installation, please read this installation and operating manual carefully. Failure to do so endangers your safety and the safety of others.
The bike carrier for the towbar is intended solely for transporting bicycles. Only bicycles weighing up to 25 kg each may be transported on the bike carrier. The bike carrier is not suitable for off-road use.
The towbar must be suitable for mounting a bike carrier:
- D-value of the towball: at least 6.7 kN (see the type plate on the towbar)
- Towbar material: at least St 52-3 (see the nameplate on the towbar)
Never exceed the maximum load capacity of the bike carrier or the nose weight of the towbar. The bike carrier and bicycles must not cause the vehicle’s gross vehicle weight rating or maximum allowable axle load (see vehicle owner’s manual) to be exceeded.
A second rearview mirror (right-side exterior mirror) is required when using the bike carrier.
Secure the bicycles on the bike carrier as evenly as possible with a low center of gravity, and secure them against falling off using brackets on the bicycle frame and tensioning straps on the front and rear wheels. Secure the bicycles on the bike carrier to prevent them from rolling away or tipping over. Mount heavy bicycles closer to the vehicle and lighter bicycles (e.g., children’s bikes) further back on the bike carrier. Before loading, remove child seats, loose items (e.g., water bottles, saddle bags, etc.). Do not cover the bicycles with tarps, protective covers, or similar items. Stow heavy loads in the trunk as far forward in the vehicle as possible to prevent excessive rear-end weight.
The vehicle’s handling, braking performance, and susceptibility to crosswinds will change. Do not exceed the maximum speed of 130 km/h.
Objects that are difficult to see, poles, or horizontal panels must not protrude from the sides. If the load protrudes more than 40 cm beyond the outer edge of the light-emitting surfaces of the side marker lights or tail lights of the rear carrier system, it must be marked: laterally no more than 40 cm from its edge and no more than 1.5 m above the road surface, with a white light at the front and a red light at the rear. The distance between the tail lights, turn signals, and reflectors (other than triangular ones) and the outer contours of the vehicle must not exceed 40 cm.
When transporting bicycles, mark the wheels protruding from the sides separately. When driving at night, cover the reflectors on the wheels to prevent distortion of the vehicle’s rear lighting and to ensure that other road users are not obstructed or misled.
The vehicle owner is responsible for ensuring that their vision and hearing are not impaired by the load or the condition of the vehicle. They must ensure that the vehicle and its load comply with regulations and that the vehicle’s road safety is not compromised by the load. Required lights and lighting units must be present and in working order even during the day.
Check all bolts and fasteners on the bike carrier and the bicycles after each installation, before every trip, and after long trips; tighten them if necessary, and check them again at appropriate intervals. On rough roads, check the bolts and fasteners on the bike carrier and the bicycles at shorter intervals. Failure to do so may cause the bike carrier or the bicycles to come loose, potentially injuring you or others and/or causing property damage.
Do not use any lubricants on the bolts. This can cause the bolts to loosen on their own, and the bike carrier or the bicycles may come loose, potentially injuring you or others and/or causing property damage.
Have repairs or part replacements performed by a qualified service center. Only use genuine replacement parts available from your authorized dealer.
Degrease the towball before installation!

Caution

Remove the bike carrier when not in use.
After each installation and before every ride, check that the lighting unit is working properly and that the bike carrier is securely fastened.
The number plate on the bike carrier must match the vehicle’s official number plate and be clearly legible.
The vehicle’s number plate and the bike carrier’s lighting unit must not be obscured.
While driving, the driver should check the bike carrier and the bicycles for any shifting or movement by looking in the rearview mirror. If any changes are detected, reduce speed and proceed to the nearest safe stopping point to retighten the bolts and fasteners on the bike carrier and bicycles.
Remove the bike carrier before using a car wash.
When entering or passing through certain areas, be aware of the vehicle’s increased width and height.
These installation and operating instructions contain the general approval for the bike carrier for use with a towbar and must always be carried in the vehicle.
Observe the applicable legal regulations for the use of bike carriers in other countries.
