Close vent screw on air hose 4. Remove the valve cap from the tire valve. Screw air hose 4 with union nut 5 onto the collapsible tire valve. Make sure electric air pump switch 2 is set to 0.

The electric air pump should now be switched off. If the tire inflation pressure is above 51 psi (3.5 bar), release excess tire inflation pressure using the vent screw on air hose 4. ! Do not operate the electric air pump longer than 6 minutes without interruption. Otherwise it may overheat. You may operate the electric air pump again after it has cooled off. Press 0 on electric air pump switch 2. ! The cigarette lighter ( page 270) is not designed for use with the electric air pump.
