Warning – damage risk for RFT or UHP tires!
FCracks might occur 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 Ger-
man and English! (www.wdk.de: mounting/
demounting instructions – tire overheating)
Before mounting put the tire in a temperate
room.
3. Move upwards the lower bead breaking roller with
the left control lever switch on the hydraulic control
unit (Fig. 6).
i
The fine positioning (close up to just 5mm distance
from rim edge) is made with the left and central con-
trol lever switches of the hydraulic control unit.
i
To control the lower bead breaker roller or the
operations carried out on the lower part of the rim,
a mirror mounted on the sheet steel or the video
camera and monitor (accessories) can be used.
5.1.3 Demounting
Warning – hand injury danger!
Risk of crush injuries during tightening flange
rotation.
Do not insert the fingers between the tire
and the rim.
1. Operate the locking flange pedal to rotate the tighte-
ning flange (Fig. 5), press the bead of the tire with
both bead breaking rollers towards the rim shoulder
(Fig. 6).
2. Lubricate with mouting paste both rim shoulders.
i
Only when both tire beads are in the semi drop cen-
tre the operation is finished.
i
If the rim moves inside the tire during this opera-
tion break as soon as possible the bead first on the
upper side and then on the lower side.
i
In case of beads stuck on the rim (e.g. in case of
winter tires, off-road or high-profile tires) the bead
breaking rollers have to be positioned behind the
edge of the rim and then they have to be put as clo-
se as possible to the rim shoulder.

!
Once the bead breaking operations are finished ad-
just the distance between the bead breaking rollers
and the rim at 5 mm, so that when the central but-
ton (AUTO) of the hydraulic control unit is pressed
the tool arrives to the same distance. Check again
the distance every time that a translation of the
locking flange is performed.
