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 suffi cient lubricant on tire and rim.
•
Place tire on rim in sloping position (Fig. 19).
•
Depress the pedal (4, 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 fl ange of
the bead guide roller (arrow A, Fig. 20).
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 fl ange.
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 fi tted, 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 fl ange 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
fl ange, 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 infl ation of the tire release wheel clamping.
