The Drive Belt and its attachment to the axle is the most sensitive part of the kPulley. Be attentive to wear and check regularly. When the Belt shows signs of wear and tear, trim the end by cutting off the damaged area or replace it with an original spare Drive Belt.
The kPulley2 Drive Belt is not compatible with the original kPulley model, unless you have mounted the kPulley Upgrade Kit. The kPulley1 Drive Belt can be used in both models but its loose end does not contain a magnet for the beam.
For guidance on how to replace your Drive Belt, please refer to the manual for the model of your device, which can be found here.
The video below is relevant for users of the original kPulley device.
