GENERAL INFORMATION This tyre-changer has been specifically designed to demount and mount truck, bus, tractors and earth moving vehicles tyres, with rims from 14" to 56" and 2500 mm. max. diameter. Any other use is improper and therefore not authorized. Before starting any kind of work on this machine, carefully read and understand the contents of these operating instructions.
SAFETY DEVICE The tyre-changer is equipped with several safety devices to grant the utmost safety at work: 1) Check valve on the chuck opening hydraulic line (inside the rotating union, see Fig. B/1). This prevents the wheel from falling from chuck down to floor if the hydraulic circuit accidentally breaks. 2) Pilot operated seal check valve (see Fig.
UNPACKING Once the packing material has been removed, check the machine visually for integrity and make sure there are no damaged parts. Keep the packing materials out of the reach of children as they can be a source of danger. N.B.
ELECTRIC HOOK UP Before making any electric hook up, carefully check that the mains voltage corresponds to the data given on the voltage tag (positioned near the tyre-changer plug). Following requirements are essential: Alimentazione Interruttore Interruttore the system must be equipped with a good earthing circuit Power supply Switch Switch...

KEY TO THE WARNINGS 10.1 Danger of crushing hands in the chuck jaws. Pay the utmost attention during tool holder tilting operation. Danger of crushing feet during chuck rotation or opening operation Danger of crushing between chuck holder and tyre- changer platform.
WORKING POSITION Diagram B/8 shows the several working positions (A, B, C, D) that will be described in the following pages. Working from these positions ensures greater precision, higher speed and safety level to the operator CHECK OF CORRECT OPERATION Before using the tyre-changer, some checks shall be made to grant correct operation.

ATTENTION! When the chuck holder moves down, it creates potential crushing points. Always work in the positions given by this guide, keeping outside the action range of moving arms. move the joystick (ref.1 fig. C page 9) leftwards (D): the chuck holder (8, Fig. A) must also move leftwards and, at the same time, the tool holder (14, Fig.
WHEEL CLAMPING 13.1 WARNING! In clamping phase, make sure the clamps have been correctly positioned on the rim, so preventing the wheel from falling off. 1) Set the mobile control unit in position B (Fig. B/8, page 13) 2) Tilt the tool holder to rest position (14, fig. D) 3) Use the joystick to move the chuck leftwards until there’s place enough to let the wheel be set on the platform.
4) Use the joystick to keep on moving the chuck arm up and down to centre the chuck (9, fig. A) to the rim 5) With the jaws (10, fig. A) closed, move the chuck against the wheel, then use the switch (5, fig. C, page 9) to open the jaws so clamping the rim from inside, in the most suitable position according to the kind of rim (to be chosen among those shown in Fig.
ATTENTION! Do not leave working area with a wheel clamped on the tyre-changer and lifted up from floor. CLAMPING EXTENSIONS Rims having diameter over 46" without central hole flange can be clamped with the kit of 4 extensions, item 140/90 (available on demand) Insert the extension on the support (bayonet-like mounting) and lock it by the wing nut (see fig.
Page 17
5) Let the wheel rotate and, at the same time, let the bead breaking disk move forward, with a stick-slip motion, following the rim profile as well as possible. 6) Go on until the first bead is fully detached. To facilitate this operation, grease tyre bead and rim edge while the wheel is rotating. ATTENTION! To avoid any risk when greasing the beads, make the wheel rotate CLOCKWISE if you are greasing the outer bead, COUNTERCLOCKWISE if you are greasing the inner bead.
SMONTAGGIO Tubeless tyres can be removed in two different ways: 1) If the wheel doesn’t present any particular difficulty, after bead breaking proceed pushing the bead breaking disk against the tyre inner side until the two beads get out of the rim (see fig. H). 2) if the wheel is a SUPERSINGLE type, or particularly hard anyway, it is not possible to proceed as described above.
Set the mobile control unit in work position B (fig. B/8, page 13) Move the finger tool until the red spot in it is about 3 cm. inside the rim. Insert the lever (17, fig. I) between rim and bead, at the right of the tool. Keeping the lever pressed, move the wheel down until the rim edge is at about 5mm.

Set the mobile control unit in work position C (fig. B/8) 6) Set the disk against the second bead and turn the chuck until the gripper is in the lowest position (at 6 o’clock) 7) move the disk away from the wheel 8) remove the gripper and reinstall it again in the lowest position (at 6 o’clock) but out of the second bead (see.
Page 21
MOUNTING OPERATION WITH FINGER TOOL 1) proceed as described in point 1,2,3,4,5 of “Mounting operation with disk” section. 2) Move the tool arm to rest position, then move it to the inner side of the tyre and hook it in this position.
TUBR TYRES 13.3 BEAD BREAKING ATTENTION! When deflating the tyre it is necessary to unscrew the valve ring nut so that the valve, when setting back inside of the rim, doesn’t constitute an obstacle for bead breaking. Proceed with bead breaking operations as described for Tubeless tyres. But, with tube tyres, it is necessary to stop the disk right after the detachment of the disk to avoid damaging both valve and tube.
Set the mobile control unit in work position D (fig. B/8, page 21) 10) Lift the tool arm and, by means of the proper knob, turn the tool by 180°. Move the tool arm to the inside of the wheel and lower it to work position, setting it between rim and bead. Move it until the bead is close to the rim front edge (it is recommended to perform this operation while turning the wheel) 11) Move the rim of about 4-5 cm.
Page 24
5) Lift the rim with hooked tyre and let it rotate counterclockwise of about 15-20 cm. The tyre will set itself slantways. 6) set the tool arm to rest position, then move it to the tyre inner side and hook it in this position. 7) make sure that the finger tool is positioned on the wheel side.
Page 25
16) Turn the chuck until the valve is set in lowest position (at 6 o’clock) 17) Inflate the tube a little bit (until there’s no wrinkle left) to avoid pinching it when mounting the second bead. 18) Mount an extension on the valve, then remove the ring nut. Note: this operation allows the valve to be free and not to get torn when mounting the second bead.
WHEELS WITH SPLIT RINGS 13.4 BEAD BREAKING AND REMOVING WHEELS WITH 3-SEGMENT SPLIT RING 1) Clamp the wheel on the chuck, as previously described, and make sure it is well deflated. Set the mobile control unit in work position B (fig. B/8, page 3) Lower the tool arm (14, fig.
Page 27
set the mobile control unit in work position B (fig. B/8, page 21) 13) move the chuck leftwards until the tyre is fully detached from rim. Watch out for the valve! WHEELS WITH 5-SEGMENT SPLIT RING 1) Clamp the wheel on the chuck, as previously described, and make sure it is well deflated. set the mobile control unit in work position C (fig.
12) Move the chuck leftward until the tyre (with the split ring) is pulled out of the rim 13) Remove the rim from the chuck 14) Set the tyre on the platform with the split ring turned toward the chuck 15) Lock the split ring on the chuck as described in par.

TROUBLE SHOOTING After having turned the main switch ON, There’s a slowing down of the tyre- on the power pack, the general warning changer’s movements, as well as too light doesn’t light on and commands do poor power. not work. 1) the power plug is not inserted Oil in power pack is below minimum level 2) no power from the mains electric supply...
HANDLING The tyre-changer has two slots (1 and 2, Fig. A) expressly made for moving the machine by means of a fork truck with lifting capacity of min. 2000 kg. and fork length of at least 1300mm. Before moving the machine, position the carriages (chuck and tool) in the middle of the machine as to keep balance during handling.
SCRAPPING Whenever you decide to scrap the machine, it is advisable to make it unusable by disconnecting it from power supply. Being the machine considered as a special waste, demount it in homogeneous parts and dispose of them according to the national regulations in force. Dispose of the package materials through the relevant collection centres.
