1 • Tyre preparation (fig. 25)
- Grease both the tyre (A) beads.
- Place the tyre on the rim (B)
2 • Head positioning (fig. 25a)
- Operate pedal (13) to move the head into its working position.
NB: The tool is already in the correct position for mounting the tyre, unless the type of rim
has been changed.
3 • Lower bead mounting (fig. 26)
- Place the bottom bead of the tyre underneath the tool and at the same time apply a little pressure
to the tyre by hand while starting to rotate the wheel (pedal 15) for easier bead insertion.
- Rotate until tyre mounting is complete.
4 • Upper bead positioning (fig. 27)
- Position the upper tyre bead.
Take care that the tyre does not slip underneath the tool.
5 • Bring the bead breaking unit closer
6 • Bead breaker disc positioning (fig. 28)
- Lower the bead breaker disc (control 21) (A) until it is level with the well of the rim.
7 • Upper bead mounting (fig.29)
- Rotate the wheel using pedal 15 to start mounting the upper bead. Press manually the tyre bead
to keep it inserted in the channel until the bead assembly is successfully completed (alternatively
use the bead presser IPH).
NOTE: for oversized (more than 19'') or particularly tough wheels, it is recommended the use of the
pneumatic bead presser IPH. In this case the following procedure must be applied:
- Position the bead pressing device (B1, Fig. 8) near the bead breaker disc (approximately 3-4cm).
Lower it until the bead reaches the height of the rim groove.
WARNING
Risk of crushing. Positioning the bead-pressing tool against the tyre could be dangerous in some
respects. Never place any part of the body, particularly hands between tools and wheel.
- As the turntable turns, the bead pressing tool will revolve with the tyre, keeping the bead inserted
inside the rim groove and thus avoiding any effort or danger to the operator and for the rim .
WARNING
Proceed with care in this stage to avoid applying excessive stress to the tyre. It is recommended to
slightly lift up the presser tool at 6 o'clock in order to release a little bit the pressure on the tyre bead.
- Once the mounting phased is complete, raise the bead breaker disc and the bead presser tool
(control 21).
- Return the lever-less head into its rest position (control 13).
NOTE: If the sector of the tyre bead placed between bead presser tool and disc is not kept correctly
inserted in the rim groove, it is recommended to use a supplementary bead pressing clamp (op-
tional). In this case the following procedure must be applied:
- After having positioned on the tyre the bead breaker disc, lock the bead pressing clamp on the rim
near (at approximately 3-4cm from the disc – Fig. 28).
- Rotate the wheel until the clamp is at 5 o'clock position and Check that the portion of the tyre bead
(between disc and clamp) is inserted in the groove of the rim.
- If not, position the bead pressing tool at 3 o'clock to press the bead into the rim grove.
