    Ø 0,7 Ø 0,7 MAX 0,25% Ø 0,7 ELECTRIC HOOK UP Before making any electric hook up, check to be certain that the main voltage corresponds to that stamped on the voltage tag (attached to the cord near the tire changer’s plug). It is absolutely essential that : - The system is equipped with a good grounding circuit.
  • Page 7: Layout Of Functional Parts

    LAYOUT OF FUNCTIONAL PARTS WARNING! 1 - Lifting bracket During all operations, keep hands and other parts of the body as far 2 - Self-centering chuck holding arm as possible from moving parts of the machine. Necklaces, bracelets 3 - Self-centering chuck and too large clothes, can be dangerous for the operator.
  • Page 8: Identifying Warning Signals

    IDENTIFYING WARNING SIGNALS WARNING: Unreadable and missing warning labels must be replaced immediately. Do not use the tire changer if one or more labels are missing. Do not add any object that could prevent the operator from seeing the labels. Use ref.
  • Page 9: Identification Of Control

    IDENTIFYING CONTROLS The mobile control unit (fig. C) enables the operator to work at any position around the machine. On this mobile control unit the follow- ing controls are located: -The lever (8, fig. C) which in position [a] lifts the chuck arm and in position [b] lowers it; in position [c] moves the tool holder arm and the sliding table towards the self-centering chuck and in position [d] moves them away.
  • Page 10 First use handle (15, Fig. D) to tip the arm to this position. CAUTION! Do not move your face close to the tool carrier arm when you release it to tip it as needed. 1) Move the joystick (8, Fig. C) up (a): the spindle carrier arm (2, Fig. A) should lift; move the joystick down (b): the arm should lower. DANGER! When the spindle carrier arm is lowered, there is always a potential for crushing anything in its movement range.
  • Page 11: Operation

    OPERATION RIM CLAMPING 13.1 WARNING! In rim clamping, make sure that jaws are properly positioned on the rim, so as to prevent the tire from falling over 1) Take the mobile control unit to work position B. 2) Pull the tool-holder arm (14, fig. D) into the upright position. 3) Operating from the mobile control unit, move the sliding carriage (iten 13, fig.

    The most convenient clamping position on the rim may be selected according to figs E/1 - E/2 - E/3 - E/4 - E/5 and E/6. Always remember that the safest locking is on the central flange. For rims with a drop center clamping, clamp the wheel so that the drop center is near the outside of the rim (fig. E/1). For rims exceeding a diameter of 46"...
  • Page 13 4) Operating from the mobile control unit, manoeuvre the wheel until the outside of the rim skims the bead-losened disk (fig. F). DANGER! The bead breaker disk must NOT be pressed against the rim but against the tire bead. 5) Rotate the wheel and at the same time, advance the bead-loosener disk with small forward movements following the profile of the rim.
  • Page 14: Demounting

    DEMOUNTING Tubeless tires can be demounted in two ways: 1) If the tire is not difficult to demount, once the beads have been loosened, use the bead disk to push against the inside face of the tire until both beads come off the rim (See Fig. H). Always keep the tire rotating while pushing on it with the bead disk. 2) With Supersingle or very hard tires the procedure described above cannot be used.
  • Page 15: Mounting

    MOUNTING Tubeless tires can be mounted using either the bead loosener disk or the hook tool. If the tire is not problematic, use the bead loosener disk. If the tire is very rigid, the hook tool must be used. TIRE MOUNTING WITH DISK Follow these steps: 1) If the rim has been removed from the spindle, put it back on the spindle as described in the section on “RIM CLAMPING”.
  • Page 16 14) Move the ramp to remove the tire assembly from the spindle. 15) Remove the tire assembly. If the tire permits it, the operation described above can be speeded up by mounting both beads at the same time: - Follow the steps described under points 1,2,3,4 described above but instead of attaching the g-clamp to just the first bead (refer to point 4) clip it to both.
  • Page 17: Tubed Tires

    TUBE TIRES 13.3 BEAD LOOSENING WARNING: Release inflation valve when deflating the tire so that the valve, falling inside the rim, is not an obstacle during bead loosening Follow all the steps described previously for bead loosening tubeless tires. With tube tires, however, stop disk movement as soon as the bead has loosened to avoid damaging the tube inflation valve. DEMOUNTING Take the mobile control unit to work position C.

    Take the mobile control unit to work position D. 10) Move the tool carrier arm to the inside face of the tire, turn the hook tool 180° and lower the arm to its work position. Insert it between rim and bead and move it until the bead is by the front edge of the rim (best to do this with the tire assembly turning). 11) Move the rim about 1.5-2 inches (4-5 cm) from the tool making sure the hook does not detach from the rim.
  • Page 19 9) Move to the outside of the tire and check the exact position of the hook visually and adjust it as needed. Then turn the spindle clock- wise until the g-clamp is at the bottom (6 o’clock). The first bead will be mounted on the rim. Remove the g-clamp.
  • Page 20: Rims With Split Ring

    DANGER! POTENTIALLY HAZARDOUS OPERATION! Do it manually only if you are certain you can keep the tire assembly balanced. For large and heavy tires an adequate lifting device must be used 30) Move the ramp to release the tire from the spindle. 31) Remove the tire.
  • Page 21 Take the mobile control unit to work position B. 14) Move the ramp towards the outside until the tire is completely off the rim. Watch out for the valve! TIRE ASSEMBLY WITH 5-SEGMENT SPLIT RINGS 1) Clamp the tire on the spindle as described previously and make sure it is deflated. Take the mobile control unit to work position C.
  • Page 22: Mounting

    12) Lower the spindle until the tire is resting on the ramp. 13) Move the ramp towards the outside until the tire together with the split ring comes completely off the rim. 14) Remove the rim from the spindle. 15) Position the tire on the ramp with the splint ring turned towards the spindle. 16) Clamp the split ring on the spindle as explained in the section of RIM CLAMPING.
  • Page 23 DANGER! PONTETIALLY HAZARDOUS OPERATION! Do it manually only if you are certain you can keep the tire balanced. For large and heavy tIres an adequate lifting device must be used. 9) Move the ramp to free the tire from the spindle. 10) Remove the tire.
  • Page 24: Ordinary Maintenance

    DANGER!! Do not inflate the tire with the tire assembly on the spindle. Tire inflation is potentially hazardous and should only be done by removing the tire assembly from the spindle and placing it inside a safety cage. ORDINARY MAINTENANCE WARNING! Each maintenance operation must be performed only after the disconnetion of the plug from electric network.
