7.2 Inflating tyres with GT system
The GT inflation system facilitates inflation of tubeless tyres thanks to a powerful jet of air from the nozzles positioned on the
clamps.
During this phase of work the level of noise can reach 85db (A). It is advisable to use a noise protection.
•Lock the wheel on the turntable and connect the inflation head to the tyre valve.
• Make a last check to be certain that tyre and rim diameter
correspond.
•Check to be certain that rim and beads are sufficiently lubricated.
If necessary lubricate some more.
•Press the pedal down to intermediate position (B - Fig. 14).
•If the bead of tyre is not well seated, due to a strong bead, lift tyre
manually until the upper bead seals against the rim, then press
pedal all the way down (C - Fig, 14). A strong jet of air will be
released through the nozzles in the slides and this will help
the bead seal.
•Release the tyre; set the pedal in the intermediate position (B - Fig. 14) and continue to inflate the tyre with short jets of air and
constantly checking the pressure between air jets until the required pressure has been reached.
EXPLOSION HAZARD!
Never exceed 3.5 bar (51 PSI) when seating beads or inflating tyres.
If a higher inflating pressure is required remove the wheel from turntable and cpntinue the
inflation procedure inside a special protection cage (commercially available)
NEVER exceed the max. inflating pressure given by the tyre manufacturer
ALWAYS keep hands and body back from inflating tyre
ONLY specially trained personnel are allowed to perform these operations. Do not allow other
persons to operate or to stay near the tyre changer.

7.0 INFLATING
The greatest attention is called for when inflating the tyres. Keep strictly to the following instructions since
the tyre changer is NOT designed and built to protect the user (or anyone else in the vicinity of the machine) if
the tyre bursts accidentally.
A burst tyre can cause serious injury or even death of the operator.
• Check carefully that the wheel rim and the tyre are of the same size.
• Check the state of wear of the tyre and that it has no defects before beginning the inflation
stage.
• Inflate the tyre with brief jets of air, checking the pressure after every jet.
• All our tyre changers are automatically limited to a maximum inflating pressure of 3.5 bar
(51 psi). In any case NEVER EXCEED THE PRESSURE RECOMMENDED BY THE
MANUFACTURER.
•Keep your hands and body as far away as possible from the tyre.
