INFLATOR GAUGE
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.
WARNING
• Never exceed the pressure indicated by the tyre manufacturer.
• The recommended inflation pressure is specified 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.
• Inflation 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 insufficient pressure during these
types of conditions.
PHASE 4
deflation of the tyre
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).
IMPORTANT
During deflation, 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 deflated using short bursts, checking the pressure
each time until the required pressure level is reached.
PHASE 5
disconnecting the inflator gauge from the tyre valve
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.
