Important Warnings
Inadequately secured bikes and racks that are mounted or used incorrectly can come loose during travel and cause serious accidents. It
is the owners responsibility to ensure that installation, handling and use are carried out in accordance with this manual and the vehicles
owners manual. These instructions should be kept together with the vehicles operating instructions and carried in the vehicle when in
use and en route.
Check attachement hardware and load for tight fit and function:
-Before the start of any journey
-After driving a short distance following a rack or load install
-At regular intervals on long journeys
-More frequently on rough terrain
-After interruption of a journey during which the vehicle was left unsupervised (check for damage due to outside intervention)
Do not exceed the maximum load for your rack (220lbs), the maximum load specified by the vehicle manufacturer or the maximum
tongue weight specified by the hitch manufacturer. Load shall be uniformily distributed while maintaining the load as close to the
center of the rack as possible. Bikes should not be loaded in any way that causes them to extend past the vehicle and increase the
overall vehicle width beyond local transportation regulations.
Do not use any 3rd party hitch adapters or hitch extensions to mount the rack to the vehicle.
Do not use rack Off-Road*. (*Rough, washed out, boulder-and-rut-strewn backroads)
- Smooth gravel roads are not considered off-road
Do not take the rack through automatic carwash.
Do not use rear bicycle fenders with this product.
Be aware that the vehicle’s driving characteristics and braking behaviour (including in curves) might change and that the vehicle might
become vulnerable to side winds when the rack is fitted.
Depending on the carrier model, the car’s tail lights can be obstructed. If that is the case, an external light board must be fitted.
An additional number plate might be required. This should be attached to the appropriate part of the carrier in accordance with local
laws.
Folding the Rack
It is very important that all bikes are removed from the rack before attempting to fold the rack at the center pivot. Simply remove the
1/2” pin from the center pivot while supporting the upper mast. Once the pin is removed gently lower the upper mast and place the
pin through the pivot plates and through the lower mast at the second pin hole location on the pivot plates. The rack can be trans-
ported in this position without any cargo attached.
Maintenance
To ensure the longevity and safe use of your Mammoth rack it is important that the rack is regularly maintained. Check all bolts includ-
ing the hitch wedge bolt before each use. Monitor pivot points for wear, if HDPE washers are beginning to show signs of wear replace
with new HDPE washers. The hitch wedge comes prelubricated with anti sieze compound on the threads, if the wedge bolt becomes
difficult to turn relubricate with anti sieze compound. We recommend removing the rack from the receiver every two weeks to clean
the receiver to ensure that the rack does not seize in the receiver.
Remove road debris off nuts and bolts to prevent corrosion.
Routinely monitor the condition of the handle bar brackets and wheel holders and if the rubber or bungee begins to show signs of
wear or deterioration replace with new pieces. Each Mammoth rack comes coated with a durable powder coat coating. In the unlikely
event that the paint is chipped it is important that all chips are touched up with paint to ensure that the rack does not begin to rust.
