8. Mounting a tire
Always observe the applicable national guidelines
when mounting tyres.
Mounting of the tyre is feasible much more easily when
prior to mounting a common tyre lubricant is applied
onto the bead and the rim over which the bead will be
mounted. Never use other agents only
supposed
to
lubricate!
•
Clamp or adjust the rim such that the wheel valve is
ap-proximately 180 deg. from the mounting head.
•
Apply sufficient lubricant on tire and rim.
•
Place tire on rim in sloping position (
Fig. 19
).
•
Depress the pedal (
2, Fig. 17
)
to tilt the machine
post into working position.
•
Check mounting head setting, or set as
described under § 5. Setting the mounting head.
•
Position the tire relative to the mounting head
such that the lower tire bead runs from below
the mounting nose upwards over the flange of
the bead guide roller (arrow,
Fig. 20 A
).
•
Start mounting by operation of pedal
(1, Fig. 17)
.
During the mounting process observe correct
bead run, otherwise stop and correct by hand,
then proceed until the tire bead has gone
completely over the rim flange.
•
In case of tubed tires put on the tube after
mounting of the lower tire bead. To ensure that
the tube is not dam-aged once fitted, pay
attention to tube position as you continue with
tire mounting.
•
For mounting of the upper tire bead, position tire
again such that the bead runs from below the
mounting nose upwards over the flange of the
bead guide roller (arrow,
Fig. 20 B
).
•
Start mounting by operation of pedal (
1, Fig. 17
).
After a part of approximately 10 – 15 cm of the
tire has been mounted over the rim flange, stop
chuck rotation, press the mounted part of the
tire downwards directly behind the mounting
head so that the bead is forced into the drop
centre of the rim and bead tension remains low
(arrow
C
,
Fig. 21
).
•
Proceed with mounting until the tire bead is
mounted completely.
•
For inflation of the tire release wheel clamping.
