Follow the fitting machine manufacturer's operating instructions.

It is absolutely essential to ensure that the equipment is in proper working condition and that there is no damage to the disk wheel and tire.

Tire removal with a fitting machine:

IMPORTANT: Gap between unseating tool and rim flange must not exceed max. 2 cm.

Do not position unseating tool in area of valve (damage to wheel pressure sensor). Turn wheel through 180° and position unseating tool on opposite side.

Pull off balance weights on rim and clean rim to remove large pieces of dirt.

Unscrew valve insert, release air.

If tire beads are stuck, first release the tire with the pressing-off horn at several points of the wheel before actually pressing off, applying tire mounting paste between the tire and the rim flange. Only then press off the tire completely.

After completing fitting, first release clamping claws.

Inflate with air (without valve insert).

Increase pressure up to 3.3 bar (330 kPA) in stages (jumping pressure).

If the tire bead does not slip fully past the rim edge all round, do not under any circumstance increase the pressure.

Release air, force off tire bead again.

Coat rim flange with tire mounting paste again.

Inflate tire again up to 3.3 bar.

When tire beads are resting perfectly on rim shoulders, increase inflation pressure to max. 4.0 bar to "settle" tire.

Screw in valve insert and correct tire pressure.

After completion of work, balance wheels.

IMPORTANT: Advise the customer to avoid heavy acceleration in the initial period.

The mounting paste can cause the tire to turn on the rim and give rise to imbalance.
