Inflation - HPA-Faip M 928 ROYAL Betriebs- Und Wartungsanleitung

INFLATION

WARNING
Inflation is well known to be a dangerous
operation. 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.

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, 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.
- Replace the internal mechanism of the valve.
- Bring the pressure to the operating value by
pressing the Inflation push-button 20 fig. 34.
