BLE ANTICLOCKWISE ONLY IF
ADJUSTMENTS ARE REQUIRED.
12.9 Tyre inflation
TYRE INFLATING OPERATIONS
ARE HAZARDOUS FOR THE OP-
ERATOR. IF NOT PROPERLY EX-
ECUTED THEY CAN CAUSE DAM-
AGE FOR USERS OF VEHICLES
WHERE TYRES ARE FITTED.
STANDARD OR OPTIONAL INFLATING UNITS
FITTED ON TYRE CHANGERS ARE EQUIPPED
WITH A PRESSURE LIMITING DEVICE WHICH
ALMOST ELIMINATES ANY RISK OF TYRE
EXPLOSION DURING TYRE INFLATING. AN
OUTSTANDING RISK OF EXPLOSION STILL
EXISTS. THEN THE FOLLOWING PRECAU-
TIONS MUST BE RESPECTED:
•
OPERATORS SHOULD WEAR SUITABLE
PROTECTIVE CLOTHING LIKE: GLOVES,
SAFETY EYEWEAR AND EARCAPS.
•
BEFORE FITTING A TYRE, CHECK TYRE
AND RIM CONDITIONS AS WELL AS PROPER
COUPLING.
•
MAKE SURE THAT TYRE IS PROPERLY PO-
SITIONED ON THE MACHINE: THE WHEEL
OUTER PART MUST NOT BE SECURED ON
THE JAWS.
•
CORRECT WORKING POSITION: DURING
TYRE BEADING AND INFLATING THE OP-
ERATOR MUST KEEP BODY AS FAR AS POS-
SIBLE FROM THE TYRE.
•
COMPLIANCE WITH TYRE MANUFACTUR-
ER’S SPECIFICATIONS FOR TYRE INFLA
-
TION PRESSURE.
IF MEASURED PRESSURE EX-
CEEDS 4,2 BAR, IT MEANS THAT
THE PRESSURE LIMITING VALVE
AND/OR PRESSURE GAUGE IS
NOT WORKING PROPERLY. IN
THIS CASE, DEFLATE THE TIRE
ON THE SPOT AND CONTACT AN
AUTHORIZED SERVICE CENTRE
TO VERIFY EQUIPMENT OPERA-
TION. MAKE SURE OF PROPER
OPERATION BEFORE USING ANY
INFLATING EQUIPMENT.
12.9.1 Tyre inflation with pressure gauge
(on demand)
Connect the inflation device to the tyre valve and inflate
the tyre using the left pedal.
Well lubricated beads and rims make the beading in
and inflation much safer and easier.
A LIMITATION DEVICE IS PRE-
SENT IN THE AIR SUPPLY LINE
FOR THE TIRE INFLATION (4,2 ±
0,2 BAR/60 PSI).
In case the beads are not seated at 4.2 ± 0.2 bar,
release all the air from the wheel, remove it from the
tyre changer and put it in a safety cage to complete
the inflation procedure.
12.9.2 Tubeless tyre inflation device
Some types of tyres can be difficultly inflated if the
beads are not in contact with the rim.
The tubeless inflating device, assembled only on some
models, supplies air at high pressure to the selfcen-
tering chuck nozzles (
Fig. 24 Pos.1
) and therefore
facilitates the positioning of the beads against the rim
starting the normal inflation of the tyre.
In order to carry out the inflation of the tyre on these
models follow these indications:
• Connect the inflation terminal to the valve of the tyre.
• Lift the lower bead while the pedal, placed on the left
side of the machine, is pushed at its second stage,
supplying that way the required air jet.
• Go on inflating the tyre until the required pressure
is reached with the lateral pedal pushed on its first
stage.
