1. Connect an air hose (6mm or ¼ inches inside diameter) to the grooved fitting of the air tank to your compressor (pressure of 12-15 bars or 174-218 Psi).
2. Lubricate the beads. Mount the tyre to the wheel.
3. Place the mounted tyre and wheel onto the support plate of the GUN, the tyre should be slightly tilted and the lowest position of the tyre in front of the valve (photo 1).
4. Install pressure valve (TIP: remove the valve core for good flow).
5. Take the GUN with both hands, aim the nozzle between the bead and the rim and rest the brace next to the valve.

6. Push the trigger ring forward and simultaneously press the handle (photo 2). The blast of air between tyre and rim will push the upper bead into position.

7. Release the trigger ring while bringing the tyre to his working pressure by using the handle (photo 3).
8. Install the valve core.

TIP:

Tubeless tyres mounted on asymmetric rims can't be inflated if the beads are lying on the wide flange. Therefore turn the wheel with the wide flange upwards.
