Description of operation
Clamping of the rim, tilting of the machine post and
locking of the mounting head in its working position
are effected pneumatically.
The four-jaw chuck is driven by means of an electric
motor via V-belt and worm gear.
Control of machine operations is by means of a
pedals which are arranged on a control unit.
Locking of the mounting head in its working position
is accomplished pneumatically via a manually
operated control valve incorporated in the locking
lever on the mounting arm.
For clamping and unclamping of the wheel the entire
machine post with mounting arm and head can be
tilted to the rear without conditioning the working
position. This means wheels of identical size can be
handled successively without the need for repeated
readjustment of the mounting head. The machine
post is only tilted back to its working position on the
rim fl ange.
A pneumatic tyre bead breaker for demounting tyres
fi tting tightly to the rim is incorporated in the machine
and is part of the standard equipment.
A manual tyre infl ator is also part of the equipment.
Upon special request the machine can be provided
with a jet tyre infl ating system. For its operation and
use see chapter “Infl ating the tyres”.
Basic version -
Tubeless wheels system
version
The Basic version includes the tyre changer with
single speed turntable and with bead breaker that
cannot be extended. The operation and use of the
tyre changer is identical for versions with or without
the Tubeless wheels device. The only difference
for the Tubeless version is the presence of a bead
seating for tubeless tyres which produces a powerful
air jet towards the tyre chamber, close to the contact
area between the tyre and the rim.
For fi tting, operation and use of the tubeless bead
seating system see chapter “Infl ating a tyre”.
