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 electric air pump. X Drive vehicle back or forth very slowly approximately 30 ft (10 m). This serves to better distribute the TIREFIT sealant material inside the tire. X Unscrew the air pump's air hose 5 from flange 6 of TIREFIT container 1. X Screw air hose 5 onto tire valve 9. X Inflate the tire again. 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 inflation.

You may operate the air pump again after it has cooled off. X G Warning! If a tire inflation pressure of 26 psi (1.8 bar) is not attained, the tire is too severely damaged for TIREFIT to provide a reliable tire repair. In this case, TIREFIT cannot properly seal the tire.
