WARNING
• Hold the connection (Z) firmly using a 16mm spanner when tightening to the
compressor or air source to avoid accidental breakage of the gauge.
• Ensure that there are no air or nitrogen leaks due to incorrect installation of
the inlet and outlet hose from the inflator gauge.
3. Check that the inflator gauge is in working order by squeezing the handle
(M) and firmly holding the end of the hose (X) to avoid sudden movement
of the hose caused by the pressure of air or nitrogen.
WARNING
To avoid damage or injury, direct the airflow away from people, animals or
objects before squeezing the handle.
4. Verify that the air or gas only flows through the connector (X) and there are
no leaks from the other connections.
The inflator gauge can be hung using the hole (L) that is located at the
top of the rubber protection.
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 of the connection itself.
WARNING
This connection opens a mechanism inside the valve to allow the passage
of air or nitrogen through the pressure gauge, from the source to the tyre
and vice versa. Ensure that no leaks of air or nitrogen are present at the
connections as this could cause the inflator gauge to give a false reading.
PHASE 3
Tyre pressure measurement and inflation
Once the gauge is connected to the tyre valve (as described in PHASE 2),
with the handle in resting position (M), the dial pointer (B) will indicate the
pressure value detected in the tyre.
Squeeze the handle (M) to introduce air/nitrogen into the tyre through the
valve and inflate the tyre. Inflation will stop if the handle is released.

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.
