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 flange.
A pneumatic tyre bead breaker for demounting tyres
fitting tightly to the rim is incorporated in the machine
and is part of the standard equipment.
A manual tyre inflator is also part of the equipment.
Upon special request the machine can be provided with
a jet tyre inflating system. For its operation and use
see chapter "Inflating the tyres".
T 3300-24 BS
T 3300-24 BS tyre changer operation and use are identical
to those of the T 3300-24. The only difference compared
with T 3300-24 BS is the added pedal-operated tyre
inflating device and bead seating of tubeless tyres
through the "Nozzle" inflating system.
For fitting, operation and use of the inflating system
see chapter "Inflating a tyre".
T 3300-24 2-speed / 2-speed BS
With the 2-speed versions the chuck can be operated
with two speeds (Fig. 1, Item 12).
Furthermore these machines have the added possibility
to readjust the bead breaker blade (Fig. 7).
The T 3300-24 2-speed BS is furthermore provided with
the BS tyre inflating system as specified above.
