Be sure that the bead is inserted in the drop centre
of the rim in order to eliminate bead yields; in order
to make his operation easier, it is suggested, during
rotation of the locking plate, to assist with a bit of
pressure the insertion of the bead in the rim.
i
In case of tires with tube, use the locking knob to
unlock the horizontal arm and move it to free the
working area; place the rim so that the valve hole of
the tube is positioned at about 90° degrees relatively
to the mounting tool position and insert, if needed,
the tube.
5. Repeat the same operations for the insertion of the
second bead.
i
In case of RFT or UPH tires, in order to hold the
bead inside the semi drop centre, the use of acces-
sories like clamps, wedges or of the TCE 200 bead
breaker is suggested.
