pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation
compressor during this phase.

compressor for longer than eight minutes
at a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.

Tire pressure of at least 180 kPa
(1.8 bar/26 psi) is not reached
If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:
XPress the on/off switch on the tire inflation
compressor to 0.
The tire inflation compressor is switched
off.XUnscrew the filler hose from the valve of
the faulty tire.XVery slowly drive forwards or reverse
approximately 30 ft (10 m).XPump up the tire again.GWARNING
If after five minutes a pressure of 180 kPa
(1.8 bar/26 psi) cannot be achieved, the tire
is too badly damaged to be repaired reliably
using TIREFIT.
In this case TIREFIT cannot seal the tire
properly.
Do not drive any further.
