The tyre inflation compressor is switched on.
The tyre is inflated. Fir st, tyre sealant is pum‐

ri se toappr oximately 500 kPa (5 bar/73 psi). Do not switch off
the ty reinflation compres‐
sor during this phase. #
Let the tyre inflation compressor runfo r a
maximum of ten minu tes.
The tyre should then ha veattained a tyre
pressure of at least 200 kPa (2.0 bar/

If tyre sealant leaks out, make sure you clean the
af fected area as quickly as possible. It is prefera‐
ble touse clean water.

ie ved
If th e specified tyre pressure is not achie ved
af te rth e specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
