PHaSE 2
Connection to the tyre valve
1. If present, unscrew the protective valve cap.
2. To attach the connection (X) of the inflation hose, press lever (A), insert the
opening of the connection onto the threaded part of the valve and press
axially to avoid damaging the valve - then release lever (A) to anchor the
connection to the thread of the valve. Complete the operation by turning
the connection one half-turn clockwise in order to correctly compress the
gasket.
WaRNING
The connection just made opens the core inside the valve, allowing air or
nitrogen to flow from the inflator gauge to the tyre and vice versa. Make sure
that there are no leaks in the coupling of the components, as this could distort
the reading of the instrument.
PHaSE 3
Tyre pressure measurement and inflation
Once the inflator gauge is connected to the tyre valve (as described in PHASE
2), with the handle in resting position (M), the display (B) is automatically
activated and after an initial start-up phase (in which all segments of the
LCD screen are shown) shows the pressure value detected in the tyre - the
reading will be possible once the tyre pressure has stabilised, usually after a
few seconds.
To inflate the tyre, apply pressure to the handle (M) so that air/nitrogen enters
the tyre through the valve; the inflation operation stops when the handle is
released.
IMPORTaNT
During the inflation phase, to prevent excessive pressure from damaging the
instrument, the measuring system is automatically excluded. In this phase the
display shows horizontal segments which remain visible until the handle is
released.
These segments indicate that the inflator gauge is switched on and in the
detecting phase, but that the sensor is not yet detecting pressure from the tyre
or the detected pressure is not stable.
If the display does not show the pressure when the handle is released, always
ensure that the connection to the tyre valve is correct. Should the inflation
handle or the discharge valve be pressed for a longer time than the maximum
switch-on time without pressure, the display will switch off. Once the handle
or discharge valve is released, pressure from the tyre will activate the inflator
gauge again.
It is therefore recommended to inflate the tyre with progressive gas injections,
alternating frequently between the pressure phase on the handle (inflation) and
the release phase (reading), until the desired value is reached.
WaRNINGS
• Never exceed the pressure levels specified by the tyre manufacturer.
• The optimum inflation pressure is specified by the vehicle manufacturer
depending on various factors, such as load, axle, etc.
• It is preferable to inflate when the tyres are cold (between 15°C and 25°C).
Factors such as outside temperature, stresses and driving speed cause
changes in tyre temperature and consequently change the tyre pressure
16
value: for example, a 10°C increase in tyre air temperature corresponds to a
pressure increase of approximately 0.1 bar
when the tyre is warm, it is recommended that the factors outlined above be
taken into account and that the pressure be corrected only if it is insufficient
for the current operating conditions.
PHaSE 4
Deflation of the tyre
If excessive tyre pressure is detected on the display (B), it can be gradually
reduced by pressing the discharge valve (S).
IMPORTaNT
During the deflation operation, the measuring system is excluded and the
display shows the horizontal segments, so it is not possible to monitor the
pressure drop directly. After the maximum no-pressure switch-on time,
the display switches off. As soon as the discharge valve (S) is released, the
display will return to show the pressure value. It is recommended that the tyre
be deflated by progressive air/nitrogen subtractions, alternating frequently
between deflating and reading the pressure, until the desired value is reached.
PHaSE 5
Disconnecting the inflator gauge from the tyre valve
1. Press the lever (A) and disconnect the fitting (X) from the tyre valve by retracting
it axially.
2. Screw the protective valve cap, if present.
