Tyre Mounting - TECO 100 Variant Manuel D'utilisation

10 • Lower bead demounting (fig. 23)(Using tool-carrying head)
- Place the tool on the edge of the rim (A).
- Push the bead breaker disc against the bottom bead (B) using control 23.
- Using control 28, operate the hook engaging the bottom bead of the tyre (C-D).
- Check that the tool is correctly coupled with the tyre bead.
- Using the control valve 23, lift the lower tyre bead till the upper edge height of the rim.
- Operate on the control 28 to get the machine ready for the subsequent demounting operation
(performed with the wheel at a standstill and not in rotation - D).
- Operate pedal 15 to rotate the wheel until the tyre is completely demounted from the rim (E).
11 • Lower bead demounting without using the lever-less head (fig. 24) (Quick system)
- Press the pedal 13 to return the vertical post in its rest position (arm laterally tilted).
- Operate control 23 and raise the bottom bead of the tyre (A) until it is level with the top bead of the
rim (B).
- Command disc penetration by pressing push-button (26).
- Start wheel rotation (pedal 15) and at the same time raise the disc by tapping on (control 23). Rotate
until the tyre is completely demounted.
11a • Lower bead demounting
- It might be necessary to use the upper bead breaking arm with the bead breaking disc rotated
by 180° for rims with an internal drop centre (reverse rims-see "Practical hints, advice and useful
information" on page 26). In this case the quick demounting procedure (paragraph 11) must be
applied.
12 • Demounting complete
- Once demounting is finished, return the lower arm totally downwards (control 23), unlock the bead
breaking unit using button 27, tilt the column (pedal 13) and, at the end, remove the tyre.
NB: in this configuration the machine is ready to handle a series of wheels featuring a similar size.
ImPORTANT: remember that if the type of tyre is changed, the horizontal and vertical arms
must be unlocked before starting any other demounting operation.
To make full use of all the characteristics of a tyre and have safety in use guaranteed, a series of
precautions must be taken when choosing and fitting tyres.
The tyre sizes, construction and service characteristics are provided by the markings on its sidewall.
Once the appropriate tyre has been chosen from those approved for use on the vehicle, the mounting
procedure can begin.
CAUTION
When mounting a new tyre, replace the inner tube in tube type tyres and the valve in tubeless
types.
CAUTION
Always check that the tyre/rim combination is correct in terms of compatibility (tubeless tyre on
tubeless rim; tube type tyre on tube type rim) and geometrical size (keying diameter, cross-section
width, Off-Set and shoulder profile) before mounting.
Also check that rims are not deformed, that their fixing holes have not become oval, that they are
not scaled or rusty and that they do not have sharp burrs on the valve holes.
Check that the tyre is in good condition with no signs of damage.
