INFLATOR GAUGE
WONDER SPA
IMPORTANT
To prevent excessive pressure from damaging the instrument,
duringtheinflationphasethemeasuringsystemisautomatically
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
andthedialischeckedfrequentlyuntiltherequiredpressure
is reached.

Ifthedial(B)showsthatthereisexcessivepressureinthetyre,thisvaluecan
bereducedgraduallybypressingthedischargevalve(S).

1. Press the lever (A) and remove the connection (X) from the tyre valve
payingattentionnottobendthevalvestem.
2. Replace, where present, the valve cap onto the valve stem.
WARNING
•Neverexceedthepressureindicatedbythetyremanufacturer.
•The recommended ination pressure is specied by the car
manufacturer and depends on various factors like the number
ofaxles,axleweightor,forexample,whenavehicleiscarrying
additional weight.
•Inationshouldbecarriedoutwhentyresarecold(bestbetween
15°and 25°C). Factors such as external temperature, stress and
speeddeterminechangesintyretemperatureandconsequently
changethetyrepressurevalue:forexample,atyreairtemperature
increase of 10°C corresponds to a pressure increase of approx. 10
kPa(0.1bar,1.5psi).Ifthepressureischeckedwhenthetyresare
warm, this should be taken into account and the pressure should
be corrected only if there is insucient pressure during these
typesofconditions.
IMPORTANT
Duringdeation,themeasuringsystemis excludedandthedial
hand is positioned on the reference (black square), so it is not
possibletodirectlymonitorthepressuredrop.Areadingcanbe
taken as soon as the discharge valve is released. It is recommended
thatthetyreisdeatedusingshortbursts,checkingthepressure
each time until the required pressure level is reached.
