on the tire infla‐
tion compressor.
The tire inflation compressor is switched on.
The tire is inflated. First, tire sealant is pum‐
ped into the tire. The pressure may briefly
rise to approximately 500 kPa (5 bar/73 psi).
Do not switch off the tire inflation compres‐
sor during this phase!
#
Let the tire inflation compressor run for a
maximum of ten minutes.
The tire should then have attained a tire
pressure of at least 200 kPa (2.0 bar/
29 psi).
If tire sealant leaks out, make sure you clean the
affected area as quickly as possible. It is prefera‐
ble to use clean water.
If you get tire sealant on your clothing, have it
cleaned as soon as possible with perchloroethy‐
lene.
