Preparation A:

Tire size adjustment

For some tyre sizes an adjustment of the chain dimension is necessary

Check your tyre dimension
Look for it in the dimension setup table (p. 4 & 5)
If necessary, remove adjustment elements (marked yellow) with the enclosed tool as shown in figures 3a-3c.

Explanation table (page 4 & 5)

OK = no adjustment necessary
-1 = remove 1 element
-2 = remove 2 elements

etc.
For removing 2 or 4 elements, always remove the opposite elements. Keep the removed parts –this chain can be reused for other tyre dimension.

Note: These instructions are generally valid and non-binding and are results of tests and our experience. Therefore, a fitting test before the first use is urgently recommended.
Check the fit of the chain after approx. 50m. Readjust if needed (remove more adjustment elements if the chain does NOT pull automatically on the tyre).

Preparation B:

Wheel bolt adapter

To adjust the adapter, remove the wheel cover and wheel bolt caps. Remove any dirt, snow or ice.

1a Move the slide switch of the ratchet to the “open” position. Please follow the directional arrows in marked order.
1b Pull out the cable on which the adapter is fixed.
2a Now check whether the pre-assembled adapter fits onto the wheel bolt.
2b The clamp must be placed straight and completely on the hexagon of the wheel bolt for secure attachment.
3a If the adapter is too small and is not fitting on the wheel bolt, please take the next size of the clamp and the sleeve, mount it on the adapter and try it again. The offscrewing and screwing together is happening by hand.
3b The hexagon of the clamp has to be pushed completely through the opening of the sleeve. So the clamp can be fastened correctly to the wheel bolt.

Preparation C:

Wheel-offset adjustment

If the adapter touches the rim, the adapter must be extended.
As principle: Screw the adapter as close as possible to the rim without it touching the rim ( as in Fig. 3).
There are three different variants to extend the adapter. These three options are shown in the picture. The offscrewing and screwing together is happening by hand.
When the handle no longer touches the rim, the adaptation is complete.
