The electric air pump is switched on and
inflates the tire.

First, the sealing is pumped into the tire.
The pressure may briefly rise to up to 73 psi
(5 bar). This is normal and not an indication
of a malfunction. Do not switch off the elec-
tric air pump.
X
Let the electric air pump inflate the tire for
approximately 5 minutes.
The pressure gauge must display at least
26 psi (1.8 bar).
G
Warning!
The air hose can become hot during infla-
tion. Please exercise appropriate caution.
!
Do not operate the electric air pump lon-
ger than 6 minutes without interruption.
Otherwise it may overheat.
You may operate the air pump again after
it has cooled off.

X
Screw air hose 5 onto tire valve 9.
X
Inflate the tire again.
G
Warning!
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, the tire is too severely dam-
aged for TIREFIT to provide a reliable tire
repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.
