European style high-performance wheels (asymmetric curvature) - fig. 8b: some Euro-
pean wheels have rims with very pronounced curves C, except in the area of the valve
hole A where the curvature is less pronounced B. On these wheels the bead must first
be broken in correspondence with the valve hole, on both the top and bottom sides of
the wheel.
Wheels with low pressure indicator system - fig. 10c: see "Procedure for wheels with
valve or band-type sensors"
N.B.:
When working on weak rims (i.e. with
central well with thin, projecting edges
- see side), or rims with gaps, we re-
commend use of the universal closed
centre rim flange accessory.
PRACTICAL HINTS, RECOMMENDATIONS
AND IMPORTANT INFORMATION
WARNING
Must be read before using the ARTIGLIO 50
The following information is very important. It will simplify the operator's job and/or
clear up any doubts which might arise
• During the tyre demount operation with wheels that have particularly stuck beads, as
well as carefully lubricating the disk and the bead area, we suggest to insist turning the rim
in the opposite direction (anticlockwise) while keeping the disk pressed and making the
penetration as for the normal operation that is carried out by turning the rim clockwise.
• During demounting, over-lubrication and/or an unusually shaped rim edge may cause
the tyre to slip on the rim, making demounting difficult. First, try using the bead breaker
disc in an upward direction to raise the tyre. Otherwise, to speed up the procedure simply
place the manual Help accessory between the tyre and the edge of the rim. This will allow
the bead to be lifted quickly off the rim so that it can be demounted (fig.34).
• During demounting, if the tool is unable to completely overturn the tyre bead to allow
demounting to start, the tyre bead may still be, or just have been, inserted at 180° to the
demounting zone. In this case it is essential to restore the ideal condition, with the tyre
bead inside the well of the rim. This operation can be assisted with any tool you wish
(clamp provided, pliers, bead presser or lever) (fig.34A).
• During demounting, if the tool is unable to keep the tyre bead engaged to allow de-
mounting to start, the tyre bead may still be inserted on the underside. Use the bead
breaker disc in an upward direction both to break the tyre bead again and to help to
maintain a grip on it (fig. 34B).
