Function
Wheel placement:
+ Complete lifting/lowering of the wheel lifter: press the pedal shortly and energetically.
+ Gradual lowering of the wheel lifter: press the pedal continuously and gently.
+ Wheel lifter stop: release the pedal.
Blocking (pushing the pedal down) and release (push-
ing the pedal upwards) of the tightening flange.
Wheel inflation.
Rotation of tightening flange:
+ Clockwise (pushing the pedal down); continue to push to increase the speed of the
flange rotation.
+ Anti-clockwise (pushing the pedal upwards).
Bead breaking. Both bead-breaking rollers are fitted on movable supports
and are locked with a clutch pin: their symmetrical lay out, together with
the possibility of moving the locking plate, allow optimal positioning.
Makes the introduction of the mounting lever and the bead breaking of
the upper tire bead in the semi drop centre easier. At the end of the ope-
rations the roller holding arm is tilted upwards when a spring is relea-
sed or automatically with the displacement of the upper limit stop.
Bead breaking of the lower tire bead in the semi drop centre and as coun-
ter-support for the side of the tire in case of heavy tires (demoun-
ting aid). Moved downwards at the end of the operations.
Extra aid for bead breaking. This arm is used during mounting to lead safely, for examp-
le, the upper bead of the tire in the semi drop centre (e. g. in case of RFT or UHP tires).
Hydraulic control drive:
16a. Left lever: lifting/lowering of lower bead breaker arm.
16b. Central lever: sliding (forward/backward) of the tightening flange.
16c. Right lever: lifting/lowering of upper bead breaker arm.
16d. Left button: clockwise rotation of mounting tool.
16e. Central button (AUTO): automatic positioning of mounting tool.
16f. Right button: anti-clockwise rotation of mounting tool.
16g. Side joystick: tool holder arm movement.
16h. Side lever: lifting/lowering of bead pressing device arm.
16i. Led: machine power supply indication.
Demounting and mounting of the tire. The tool can be positi-
oned by means of hydraulicmovements and can be rotated with the pe-
dal in order to use the two parts which compose it:
+ Flat tool: demounting of the 2° bead and mounting of the 1° and 2° tire bead.
+ Curved tool: demounting of the 1° tire bead.
Bead breaking device positioning.
Mounting of particularly difficult tires. It is driven by an hydraulic pressure cylinder.
Holding the centring cones and quick lock nut.
Inflates tubeless tires. Inflation is achieved through high pressu-
re blowing that positions the tire bead on the rim edge. The air tank (com-
pliant to UE 87/404) has a capacity of 18 litres of compressed air.
Tire inflation check. The manometer is compliant to CEE 87/217 directive.
Tire defl ation.
Support for mounting paste.
Holds the bead lifting lever.
Used for lifting the tire edge during demounting and mounting phases.
