The tire inflation compressor is switched on.
The tire is inflated.
First, tire sealant is pumped into the tire. The
pressure may briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
Let the tire inflation compressor run for a
X
maximum of ten minutes. The tire should then
have attained a pressure of at least 200 kPa
(2.0 bar/29 psi).
If a pressure of 200 kPa (2.0 bar/29 psi) has
been attained after five minutes, see "Tire pres-
sure reached" ( page 318).
Y
If a tire pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after five minutes, see "Tire
pressure not reached" (
If tire sealant has escaped, clean it off affected
areas as quickly as possible. Use plain water if
possible.
