a - a
rm swing Control and wheel pressure display panel
A1 - Air pressure display gauge
Pressure gauge which displays the air pressure set with the
pedal E1.
Displays the tyre pressure in bar.
A2 - Tool arm swing control
The control swings the tool arm into the working position and
locks it there.
The same control releases the tool arm and swings it outwards.
A3 - Delation button
Press this button to discharge excess air from inside the tyre.
This button can only be used during inlation of the tyre with

ead breaker disC unit funCtional Controls
B1 - Bead breaker disc penetration control
At the start of the bead breaking process, when the bead breaker
disc comes into contact with the tyre, activate this "hold-to-run"
control for radial movement of the bead breaker disc.
This allows controlled disc penetration during bead breaking.
The bead breaker disc will now work around the proile of the
rim, simplifying bead breaking.
B2- Bead breaker disc positioning locking/release control
Locks the bead breaker disc in the position required.
The control has two positions:
In position
the bead breaker disc arm travels freely to allow optimal radial
positioning on the edge of the rim.
In position
pneumatically locked in place, allowing the start of the bead
breaking operations.
B3 - Lever controlling vertical movement of the bead breaker
unit
B4 - Bead breaker unit release control
