In the case of a flat tire, you do the following:
You can use for tire mounting plastic tire lever.
1. As described above dismount the appropriate wheel like in the
instructions of this manual.
2. Deflate the tire and push a tire lever under the tire wire opposite
the valve and lever the tire over the rim flange.
3. Push the second tire lever in a distance of approx.. 10cm from the
first one between tire and rim and lever again.
4. Now, you can generally lever the tire over the whole circumference
of the wheel by moving the lever and the inner tube can be
removed.
5. Dip the disassembled and inflated tube in a water bath to discover
the leak on the rising air bubbles.
6. Repair the tube according to the instructions on the repair kit or if
necessary replace it.
7. Check the tire for sharp objects that could have caused the puncture
and remove them. If the fabric of the tire is damaged, replace it.
8. Start the mounting of the tube, start by inserting the valve into the
valve hole in the rim and inflate the tube with very little air pressure
until it is wrinkle-free.
9. Now mount the tube with no creases under the tires and deflate it
again.
10. Now , starting opposite the valve, lift the tire wall over the flange
of the rim and pull it deep into the rim and lever the rest of the tire
by hand over the rim edge. Use no tire levers, as this is a risk of
damaging the tube.
11. Now push up the valve, so that the edge of the tire reaches at the
valve area the edge of the rim.
12. Pull the valve and inflate the tube to the tire manufacturer
recommended tire pressure.
