Step 4
1. Pump up the inner tube.
• In case of a large puncture: you can hear the air
escape.
• In case of a smaller puncture: submerge the inner
tube in water (for example in a bucket).
2. Dry the inner tube.
3. Mark the puncture with a ball pen.
Step 5
Repair the tube following the instructions included
in the tyre repair set. With most sets the instructions
below will suffice:
1. Clean the place of the puncture with sandpaper.
2. Let the air release from the inner tube.
3. Apply glue/solvent on an area that is slightly larger
than the sticker.
4. Let the area dry one to two minutes.
5. Remove the backing from the sticker.
6. Tightly press the sticker onto the puncture.

Step 6
1. Put back the inner tube into the tyre. The valve
casing must come straight out of the rim hole.
2. Tighten the rim nut a few turns.
3. Tighten the valve.
4. Pump up the tyre a bit, making sure that the inner
tube does not come out of the tyre.
5. Position the tyre. Use your hands.
• When making use of tyre levers, there is a big
chance of causing punctures.
• Make sure that the inner tube is not pinched
between the tyre and the valve.
• At the valve area press the valve a bit towards
the tyre and back again; this will make the inner
tube ‘jump’ into the tyre.
6. Pump up the tyre.
