The electric air pump is switched on. The
tyre is inflated.
i First, TIREFIT is pumped into the tyre. The
pressure can briefly rise to around 5 bar.
Do not switch off the compressor during
this phase.
X Let the compressor run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar.
! Do not operate the electric air pump for
longer than six minutes without a break,
otherwise it may overheat.
The air pump can be operated again once
it has cooled down.
If a pressure of 1.8 bar is not reached after
five minutes:
X Switch off and disconnect the electric ai r
pump and drive the vehicle forwards or
backwards approximately 10 m.
This distributes the TIREFIT more evenly.
X Remove the TIREFIT filler bottle from th e

X Pump up the tyre again. G
Risk of accident
If a pressure of 1.8 bar is not achieved afte r
five minutes, the tyre is too badly damaged.
