Practical hints
Flat tire
After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose can become hot during inflation.
Please exercise appropriate caution.
If this tire inflation pressure is not attained,
turn off the electric air pump,
detach the filler hose from the tire
valve, and drive vehicle back and forth
very slowly approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.
Unscrew the air pump’s air hose 5
from flange 6 of the TIREFIT
container.
Screw air hose 5 onto tire valve 7.
Inflate the tire again.
