may occur. We therefore recommend that the operator
wears ear protectors.
DANGER
Although the machine limits the pressure, it does not pro-
vide suficient protection if the tyre bursts during inlation.
Failure to comply with the instructions below will make
tyre inlation dangerous.
DANGER
NEVER exceed the pressure recommended by the tyre
manufacturer. Tyres may burst if they are inlated beyond
these limits or their structures may incur serious dam-
age not visible at the time. KEEP THE HANDS AND THE
WHOLE BODY WELL AWAY FROM THE TYRE DURING
INFLATION. Make sure you are concentrated during this
operation and check the tyre pressure continuously to
avoid excess inlation. A bursting tyre can cause serious
injury or even death.

nflating tubeless tyres
- Make sure that the wheel on which the tyre has been mounted
is irmly clamped to the turntable using the clamping device
1 ig. 31. Also make sure that the tool head and the bead
breaker unit are well clear of the working area, if possible
in the rest position.
- Fix a new valve to the rim.
- Connect the Doyfe union of the inlation line 2 ig. 31 to the
stem of the valve, after removing the cap. Inlate the tyre
by pressing Pedal 3 ig. 31. The tyre expands, bringing the
beads into the position where they create a seal.
- Continue inlating 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 the tyre pres-
sure on the Air pressure display pressure gauge 4 ig. 31
continuously to avoid over-inlating.
Inlation of tubeless tyres requires a higher air low-rate to
allow the beads to pass over the humps in the rim - see types
of proiles of tubeless tyre rims in ig. 31; to provide this, the
internal mechanism of the valve should be removed.
In terms of anchoring of the bead in its seat, the hump (H)
and double hump (H2) versions provide greater safety
in use, even if the inlation pressure is slightly lower than
recommended.
- Check from the position of the centring ridges that the beads
are properly positioned on the rim, and otherwise delate,
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
Inlation button 5 ig. 31.
- Fit the cap on the valve to protect its internal mechanism
from dust and ensure an airtight seal.
- Remove and unload the wheel as described in steps 11-12
of the "MOUNTING" section.
i
nflating tube
- Make sure that the wheel on which the tyre has been mounted
is irmly clamped to the turntable using the centring handle
1 ig. 31. Also make sure that the tool head and the bead
breaker unit are well clear of the working area, if possible
in the rest position.
- Connect the Doyfe union of the inlation line 2 ig. 31 to the
stem of the inner tube valve, after removing the cap. Inlate
-
type tyres
the tyre by pressing the relative Pedal 3 ig. 31 in short
bursts.
The inner tube gradually expands inside the tyre. As this
happens, push the inner tube valve inward to allow the air
left between the tube and the tyre to escape; this prevents
delation and possible damage to the tube.
- Inlate, taking great care that the pressure shown on the
Air pressure display gauge 4 ig. 31 NEVER exceeds the
pressure levels recommended by the tyre producer.
- Fit the cap on the valve to protect its internal mechanism
from dust and ensure an airtight seal.
- Remove and unload the wheel as described in steps 11-12
of the "MOUNTING" section.

nflation pressure
Maintaining correct pressure values is of the greatest impor-
tance for safe use of the vehicle.
Insuficient pressure causes overheating and may drastically
shorten the life of the tyre; it reduces roadholding and may
cause uneven wear (tread wear concentrated on the shoulders
of the tyre) and internal damage, and the tyre may even col-
lapse. It also increases the vehicle s fuel consumption.
Excessive pressure makes the tyre more liable to damage in
case of knocks and causes uneven wear (wear concentrated
along the centre of the tread).
The inlation pressure must be checked regularly, at least
every two weeks and before long journeys, not forgetting the
spare wheel.
The pressure must only be checked with the tyres cold, since
the pressure increases when the tyres heat up during use.
Never reduce the pressure of tyres when they are hot.
Tyres which have not been used for at least one hour, or have
travelled not more than 2 or 3 kilometres at low speed, can
be considered cold.
The inlation pressures when cold must be those speciied for
the car by the car or tyre producer.
For heavy-duty operating conditions (e.g. continuous high
speeds, towing trailers, etc.), where this is not already speci-
ied by the car s handbook, the recommended cold pressures
should be increased by 0.3 bar.

MAINTENANCE

ATTENTION
The "Spare Parts" manual does not authorise the user to do
any work on the machine except for that speciically described
in the operator's manual, but does enable the user to provide
accurate information to the after-sales service, in order to reduce
service times.
WARNING
CORMACH declines all liability for claims deriving from
the use of non-original spares or accessories.
ATTENTION
Any operation intended to modify the setting value of the
relief valves or pressure limiter is forbidden.
The manufacturer declines all liability for damage result-
ing from tampering with these valves.
WARNING
Before making any adjustments or carrying out mainte-
nance, disconnect the electricity and compressed air sup-
plies from the equipment and make sure that all moving
parts are suitably immobilised.
