DESCRIPTION OF
M 928 ROYAL TYRE
CHANGER
The M 928 ROYAL model is a universal electro-
pneumatic tyre changer, to be used with integral
wheels with drop centre featuring weights and
dimensions as described in the technical data
section.
It is designed to work effectively on:
- Conventional wheels;
- Reverse rim wheels or wheels without central
hole - (use optional kit);
- Run-flat tyres with reinforced sidewalls*.
* WARNING: There are specifically studied
procedures for this type of wheels.
NB: It may be difficult and sometimes impossi-
ble to clamp and/or demount wheels of Vintage
cars (cars out of production for over 30 years),
some types of rally wheels and non-standardised
street wheels.
User Manual M 928 ROYAL
The machine is solidly constructed. It opera-
tes with the wheel in a horizontal position for
both bead breaking and demounting/mounting
operations.
All machine movements are controlled by the
operator by means of a pedal in a pedal board
and manual controls on the console.
The M 928 ROYAL tyre changer can be used
to easily break, demount and mount any type
of the above tyres.
In any stage, the M 928 ROYAL tyre changer
operates with a clamped and perfectly centred
horizontal wheel on the turntable.
Wheel loading and unloading operations are
simplified by an ergonomic wheel lift (optional kit)
which minimises the operator effort required.
The main advantage of the M 928 ROYAL model
is that it does not have a bead lifter lever.
Its absolutely innovative operating principle
comprises:
- A wheel positioning system that makes use
of the wheel inner side and the machine axial
mounting turntable as references (an optional
reverse rim kit is supplied for rims with drop
centres on the inner side).
- An efficient manual wheel clamping system,
which makes use of the rim central hole by
means of a handle and cones (an optional
clamping kit is supplied for rims with no central
hole).
- A pneumatic bead breaking unit consisting of
two bead breaker disc holders. Its pneumatic
vertical movement is independent and activated
from the console; the disc horizontal positio-
ning is manual, mechanically activated from
the console and it allows the simultaneous
positioning of the bead breaker discs. Bead
breaking is ensured by the disc movement,
with a controlled penetration commanded by
an operator.
- A head, installed on a mobile column with a
rear opening, consists of a fixed supporting
nucleus that facilitates tyre mounting and a
pivoted mobile fixed nucleus that facilitates
an optimal tyre demounting without using the
bead lifter lever*.
* In a very few cases, an accessory supplied
called manual "help" may be of use in simplifying
demounting where excessive lubricant has been
applied or for tyres coupled to special rims.
