Remove the valve cap from valve
#
faulty tyre.
Screw filling hose 8 onto valve 7.
#
Insert plug 4 into a 12‑V‑socket in your vehi-
#
cle.
Switch on the vehicle.
#
Press on and off switch 3 on the tyre infla-
#
tion compressor.
The tyre inflation compressor is switched on.
The tyre is inflated. First, tyre sealant is pum-
ped into the tyre. The pressure may briefly rise
to approximately 500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation compressor
during this phase!
Let the tyre inflation compressor run for a
#
maximum of ten minutes.
The tyre should then have attained a tyre pres-
sure of at least 200 kPa (2.0 bar/29 psi).
If tyre 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 tyre sealant on your clothing, have it
7 on the
cleaned as soon as possible with perchloroethy-
lene.
If, after ten minutes, a tyre pressure of 200 kPa
(2.0 bar/29 psi) has not been attained:
Switch off the tyre inflation compressor.
#
Unscrew the filling hose from the valve of the
#
defective tyre.
Please note that tyre sealant may leak out when
unscrewing the filling hose.
Drive forwards or in reverse very slowly for
#
approximately 10 m.
Pump up the tyre again.
#
After a maximum of ten minutes the tyre pres-
sure must be at least 200 kPa (2.0 bar/
29 psi).
& WARNING Risk of accident due to the
specified tyre pressure not being attained
If the specified tyre pressure is not attained
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance.
The braking and driving characteristics may be
greatly impaired.
Do not continue driving.
#
Consult a qualified specialist workshop.
#
If, after ten minutes, a tyre pressure of 200 kPa
(2.0 bar/29 psi) has been attained:
& WARNING Risk of accident from driving
with sealed tyres
A tyre temporarily sealed with tyre sealant
impairs the handling characteristics and is not
suitable for higher speeds.
