Tire mounting

Danger of car accidents caused by damaged
rims or tires!
In case of tire or rim damage during mounting
dangerous or even lethal situations may
occur during driving.
€
The operator has to be specifically trained.
€
Do not exert excessive forces on the tire or
the rim, adjust the slow rotation speed.
€
Use a sufficient quantity of mounting
paste.
€
In case of anomalies, e.g. suspicious
noises, stop mounting immediately.
€
For mounting of critical rim/tire
combinations, read the Wdk publications
available in German and English!(www.
wdk.de: mounting/demounting instructions
– criteria catalogue).

Mounting preparations

Warning – damage risk for RFT or UHP tires!
Cracks in case of operation on cold tire. Tire
explosion in case of high speed.
€
Inner temperature of the tire must be at
least 15 °C.
€
Read the Wdk publications available in
German and English! (www.wdk.de:
mounting/demounting instructions – tire

5.2.2 Mounting
Warning – hand injury danger!
During locking plate rotation there is a risk of
crush injuries.
€
Do not insert the fingers between the tire
and the rim.
1. Rotate the locking plate and bring the valve between
2 o'clock and 4 o'clock position.
2. Press (and release quickly) the the tilting column
pedal to lower the column.
3. Lay the tire bead on the lower left edge of the
mounting tool tab.
4. While holding the bead in the semi-drop centre press
the rotation pedal and keep turning the locking plate
until the upper tire bead has passed close to the
mounting tool (1) and it has gone under the edge of
the rim.

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, press the tilting column
pedal to tilt the column backwards; place the rim so
that the valve hole of the tube is positioned at about
90° degrees relatively to the mounting tool position
and, if needed, the tube.
5. Repeat the same operations for the insertion of the
second bead.
