INFLATION
WARNING
Inflation is well known to be a dangerous ope-
ration. It must be carried out in accordance
with the instructions below. Safety goggles
with plain lenses and safety footwear must
be worn.
CAUTION
During this operation, noise levels assessed
at 85 dB(A) may occur. Operators are advised
to wear hearing protection devices.
DANGER
Although the machine limits the pressure, it
does not provide sufficient protection if the
tyre bursts during inflation.
Failure to comply with the instructions below
will render tyre inflation dangerous.
DANGER
NEVER exceed the pressure recommended
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
concentrated during this operation and check
tyre pressure continuously to avoid excess
inflation. A bursting tyre can cause serious
injuries or even death.

nflating 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, after 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.
"HUMP" (H)
"double HUMP" (H2)
- From the position of the centring ridges check
that the beads are properly positioned 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.
