Inflating tubeless tires

1. Ensure that the rim is held securely on the turntable
and that the mounting head and tire pressing disk
are not in contact with the tire. If possible, they
should be positioned to the farthest point.
2. Install a new valve in the rim.
3. Make sure that the entire tire has been lubricated.
4. Remove the cap from the valve and place the
inflation gun on the top of the insert to inflate the
tire.
5. Interrupt the inflation process occasionally and
check the pressure in the tire until the specified
value is reached. Do not exceed the max. pressure.
The pressure must not be greater than 3.5 bar under
any circumstances.
i
Tubeless tires need a relatively high volumetric flow
of air. If air flow is inadequate, the bead will not
pass over the hump. To increase the air flow, you
can take out the valve insert.
6. Check the connection between the tire bead and
rim.
i
The connection between the tire bead and rim must
be perfect. If there is problem, you must deflate the
tire, unseat the tire bead again and relubricate the
tire bead. Rotate the tire on the rim and then inflate
once again.
7. Screw in the valve insert.
8. Connect the inflation gun and then press the deflate
button to remove the residual air.
9. Attach the valve cap.
