IMPORTANT
To prevent excessive pressure from damaging the instrument,
duringtheinflationphasethemeasuringsystemisautomatically
excluded and the dial pointer returns to the reference (black
square). As soon as the handle is released, the pointer of the
dial will indicate the pressure value. It is recommended that
the tyre is inflated using short subsequent bursts of air/gas
andthedialischeckedfrequentlyuntiltherequiredpressure

2. Replace, where present, the valve cap onto the valve stem.
WARNING
•Neverexceedthepressureindicatedbythetyremanufacturer.
•The recommended ination pressure is specied by the car
manufacturer and depends on various factors like the number
ofaxles,axleweightor,forexample,whenavehicleiscarrying

increase of 10°C corresponds to a pressure increase of approx. 10
kPa(0.1bar,1.5psi).Ifthepressureischeckedwhenthetyresare
warm, this should be taken into account and the pressure should
be corrected only if there is insucient pressure during these
typesofconditions.
IMPORTANT
