DANGER
NEVER exceed the pressure recommen-
ded by the tyre manufacturer. Tyres may
burst if they are inflated beyond these
limits or their structures may incur serious
damage not visible at the time. KEEP
YOUR HANDS AND THE WHOLE BODY
WELL AWAY FROM THE TYRE DURING
INFLATION. Make sure you are concen-
trated during this operation and check
tyre pressure continuously to avoid excess
inflation. A bursting tyre can cause serious
injuries or even death.
Inflating tubeless tyres
- Make sure that the wheel on which the tyre
has been mounted is firmly secured to the
turntable using the clamping device 1 fig.
34. Also make sure that the tool-carrying
head and the bead breaking unit are well
clear of the working area, if possible in a
rest position.
- Fix a new valve to the rim.
- Connect the Doyfe inflator chuck 22 fig.
34 on the air hose to the valve stem, af-
ter removing the cap. Inflate the tyre by
pressing Pedal 14 fig. 34. The tyre expands
and the beads seat.
- Continue inflating up to the maximum
value of 3.5 bar to position the tyre
correctly on the rim. Make sure you are
concentrated during this operation and
check tyre pressure continuously on the
Pressure gauge display 17 fig. 34 to avoid
excess inflation.
Inflating tubeless tyres requires a higher
air flow-rate to allow the beads to bypass
the rim HUMPS - see types of rim profiles
for mounting without a camera in fig.33;
therefore, the internal mechanism of the
valve should be removed.
In terms of the bead anchoring to its site,
the HUMP (H) and double HUMP (H2)
versions (fig.33) provide greater running
safety, even if the inflation pressure is
slightly lower than the operating one.

- From the position of the centring ridges
check that the beads are properly posi-
tioned on the rim; otherwise, deflate the
tyre, break the beads as described in the
relevant section, lubricate and turn the tyre
on the rim. Repeat the mounting operation
described previously and check again.
- Replace the internal mechanism of the
valve.
- Bring the pressure to the operating value
by pressing the Inflation push-button 20
fig. 34.
- Fit the cap to the valve to protect its in-
ternal mechanism from dust and ensure
an airtight seal.
- Remove and unload the wheel as de-
scribed in steps 11-12 of the “TYRE
MOUNTING” section.
Inflating tube-type tyres
- Make sure that the wheel on which the tyre
has been mounted is firmly secured to the
turntable using the centring handle 1 fig.
34. Also make sure that the tool-carrying
head and the bead breaking unit are well
clear of the working area, if possible in a
rest position.
- Connect the Doyfe inflator chuck 22 fig. 34
on the air hose to the air chamber valve
stem, after removing the cap. Inflate the
tyre by pressing the corresponding Pedal
14 fig. 34 at short periods of time.
The inner tube gradually expands inside
the tyre. As this happens, push in the inner
