GENERAL SAFETY REGULATIONS
The use of this machine is reserved to specially trained and authorized personnel.
Any unauthorized changes or modications to the machine, in particular to its electric system, relieve the manifacturer from all liability
and warranty claims.
Removing or tampering with the safety devices installed on this machine is a violation of International Safety Regulations, and, as such,
once again relieves the manufacturer from all liability and warranty claims.
4SAFETY DEVICES
The tire changer has a number of safety devices designed to guarantee the utmost operator safety:
1. Check valve on the spindle opening hydraulic line (inside the swivel connector, see g. B/1). This prevents the wheel from falling from
the spindle if the hydraulic line is accidentally broken.
2. Pressure relief valve factory set at 1,885 PSI (130 bar) ±10% (See Fig. B/2).
This limits the pressure in the hydraulic circuit and ensure correct operation of the plant.
3. Pump motor overload shut-off (inside the electric enclosure). This provides automatic shut-off for the motor to prevent damage from
overheating. This cuts in if the motor overheats to prevent it from burning out.
4. Check valve on the chuck arm lifting hydraulic line. This prevents the chuck arm from descending when any accidental break occurs
in the hydraulic circuit.

IDENTIFYING CONTROLS
The diagram B/8 illustrates the various working positions (A,B,C,D) referred to in the following pages describing how to use the tire changer.
Use of these positions ensures greater precision, speed and safety for those using the machine.
The mobile control unit (g. 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, g. 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.
Note: in order to memorise this operation, there is a hole in the lever guard corresponding to position c.
-The chuck switch (9, g. C) when moved upwards, opens the arms of the self-centering chuck (LOCKING), and when moved down,
closes the arm of the self-centering chuck (UNLOCKING).
-The pedal (10, g. C) when pressed on the left or right side rotates the self-centering chuck in the same direction as shown by the ar-
rows placed on the foot pedal.
Both rotations can be made with two different speeds, just placing the selector (12, g. B/6) in position 1 for getting slow rotation and in
position 2 for fast rotation of the turntable
The tire changer also has:
Handle (15, Fig. D) to tip the tool carrier arm (14, Fig. 4) from its work to its non-working position and vice-versa.
Pedal (19, Fig. D) that permits alternative use of the bead-losening disk (17, Fig. D) or the hooked tool (18, Fig. D).
Pressing the emergency STOP BUTTON (12 g. C) will stop any operation in course

13.2
The most convenient clamping position on the rim may be selected according to gs E/1 - E/2 - E/3 - E/4 - E/5 and E/6.
Always remember that the safest locking is on the central ange.
For rims with a drop center clamping, clamp the wheel so that the drop center is near the outside of the rim (g. E/1).
For rims exceeding a diameter of 46" and without a ange with center hole, the rim can be clamped with the 4 clamping extensions
provided on demand (# 9299270)
(# 9299272) LIGHT-ALLOY RIM CLAMPING
A set of specialclamps - especially designed for operating on light alloy rims without damaging them - is available upon request.
These clamps are to be inserted (bayonet-like mounting) into the jaw support of the self-centering chuck (see g. E/7).
Thanks to a wing screw the clamp can be locked on the support.
Clamp the rim as illustrated in g. E/8. The specially-made alloy-rim pliers are also available (#9299272).
DANGER!
Do not walk across the work area with a wheel clamped on the tire changer and lifted up from the
oor.
TUBELESS AND SUPERSINGLE TIRES
BEAD LOSENING
1) Clamp the tire assembly on the self-centering chuck, as previously described, and ensure that the tyre is deated.
3) Lower the tool-holder arm (14, g. F) into is working position and allow it to lock.
2) Take the mobile control unit to work position C.
DANGER!

5) Rotate the wheel and at the same time, advance the bead-loosener disk with small forward movements following the prole of the
rim.
6) Continue until the rst bead is fully detached.
To facilitate this operation, lubricate the bead and the edge of the rim with tire lubricant whilst the tire assembly is rotating.
CAUTION!
To avoid all risk, lubricate the beads turning the tire assembly CLOCKWISE if you are working on the outside
face and COUNTERCLOCKWISE if working on the inside face.
Remember that the stronger the tire’s adherence to the rim, the slower must be the disk’s penetration.
7) Move the tool carrier arm (14, Fig. F) back from the edge of the rim. Release the hook, raise the arm to its non-working position, shift
it and rehook it in its second work position (Fig. G).
DANGER!
Do not hold your hands on the tool when you bring it back to its work position.
Your hand(s) could be trapped between the tool and the tire assembly.
8) Push the double headed tool lever (19, g. G) and turn the head 180° until it locks automatically. Then slide the tool-holder arm along
the sliding carriage and lock it in position.
Repeat the operation previously described until the second bead is completely loosen.
During the bead loosenig operation, the claw (18, g.G) can be lowered so that it is out of the way.
9) Take the mobile control unit to work position D.
4) Operating from the mobile control unit, manoeuvre the wheel until the outside of the rim skims the bead-losened disk (g. F).
DANGER!
The bead breaker disk must NOT be pressed against the rim but against the tire bead.

DEMOUNTING
Tubeless tires can be demounted in two ways:
1) If the tire is not difcult 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. The hook tool will have to be used as follows:
- Transfer the tool carrier arm to the outside face of the tire.
- Insert lever (17, Fig. I) between rim and bead at the right of the tool.
-Press down on the lever and lower the wheel to bring the edge of the rim about 2 inch (5 cm) from the hooked tool.
-Turn the wheel counterclockwise pressing down on lever until the bead is completely off.
-Move the tool carrier arm to its non-working position and then move it to the inside plane of the wheel.
- Rotate the wheel and at the same time move the hook tool forward inserting it between rim and bead until it is anchored to the bead
(See Fig. I).
-Move the rim 1,5-2 inch (4-5 cm) from the tool taking care that it does not unhook from the bead.
-Move the hook tool towards the outside until the red reference dot is by the outside edge of the rim.
-Place the tool carrier arm in its working position, then use bead discto push again.
-The inside face of the tite (see g. H). It is best to do this with the weel turning.
Take the mobile control unit to work position C.
Take the mobile control unit to position B.

DANGER!
When the beads come off the rim, the tire will fall. Check to make sure there are no bystanders
in the work area.
Take the mobile control unit to work position B.

15
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”.
2) Lubricate both beads and the rim with tire manufacturer recommended lubricant.
3) Attach the g-clamp to the outside edge of the rim at the highest point (See Fig. M).
CAUTION!
Make sure the g-clamp is rmly attached to the rim.
Take the mobile control unit to work position B.
4) Put the tire on the platform and lower the spindle (make sure the g-clamp is at the high point).
5) Lift the rim with the tire hooked to it and turn it counterclockwise about 6-8 inches (15-20 cm). The tire will be positioned inclined
across the rim.

6) Position the bead loosener disk against the second bead of the tire and turn the spindle until the g-clamp is at the low point (at 6
o’clock).
7) Move the disk away from the tire assembly.
8) Remove the g-clamp and replace it at 6 o’clock outside the second bead (See Fig. N).
9) Turn the spindle clockwise 90° to bring the clip to 9 o’clock.
10) Move the disk forward until it is about 0.5-1 inch (1-2 cm) inside the edge of the rim. Begin to turn the spindle clockwise, checking to
make sure that, with a 90° turn, the second bead begins to slip into the drop center.
11) When the bead is fully mounted, move the tool away from the tire assembly, tip it to its non-working position and remove the g-
clamp.
12) Position the ramp under the tire assembly, lower the spindle until the tire rests on the platform.
Take the mobile control unit to work position C.
13) Close the arms of the spindle completely. Support the tire assembly to prevent it falling off.
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.
Take the mobile control unit to work position B.

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 rst bead (refer to
point 4) clip it to both.
- Lift the rim with the tire hooked to it and turn it counterclockwise 6-8 inches (15-20 cm) (clip at 10 o’clock).
- Follow the steps described in points 10,11,12,13,14,15 above.

MOUNTING WITH THE HOOKED TOOL
1) Follow the steps described in points 1,2,3,4,5 for mounting with the disk.
2) Move the tool carrier arm to its non-working position. Move it to the inside face of the tire and rehook it at this position.
3) Check to make sure the hook tool is positioned facing the tire bead. If not, press lever (19, Fig. G) and turn it 180°.
Take the mobile control unit to work position D.
4) Move the tool forward until the red reference dot is lined up with the outside edge of the rim and about 1/4 inches (5 mm) from it
(See Fig. O).
5) Move to the outside of the tire assembly and check the exact position of the hook visually and adjust it as needed. Then turn the
spindle clockwise until the g-clamp is at the bottom (6 o’clock). The rst bead will be mounted on the rim.
6) Remove the g-clamp.
Take the mobile control unit to work position D.
7) Remove the tool from the tire.
8) Move the tool carrier arm to its non-working position. Move it to the outside face of the tire and rehook it in this position.
9) Turn the tool 180° with lever (19, Fig. G).
10) Attach the g-clamp at the bottom (6 o’clock) outside the second bead (See Fig. N).
Take the mobile control unit to work position C.
11) Turn the spindle counterclockwise to about 90° (clip at 9 o’clock).
12) Bring the tool forward until the red reference dot is lined up with the outside edge of the rim and about 1/4 inches (5 mm) from it.
Begin to turn the spindle counterclockwise and check if, after about 90° of rotation the second bead has started to slip into the drop
center. Continue turning until the g-clamp is at the bottom (6 o’clock). The second bead will now be mounted on the rim.
13) Follow the steps described in points 11, 12, 13, 14, 15 for mounting with the disk, since this will ensure that the tire assembly is removed
correctly from the machine.
Take the mobile control unit to work position C.

Turn the tire counterclockwise pressing down on lever until the tire comes completely off the rim.
DANGER!
When the beads come off the rim, the tire will fall. Check to make sure there are no bystanders in the
work area.
MOUNTING
1) If the rim has been removed from the spindle, put it back on the spindle as described in the section on “RIM CLAMPING”.
2) Lubricate both beads and the rim with tire manufacturer recommended lubricant.
3) Attach the g-clamp to the outside edge of the rim at the highest point (See Fig. R).
CAUTION!
Make sure the g-clamp is rmly attached to the rim.
4) Put the tire on the platform and lower the spindle (make sure the g-clamp is at the high point) to hook the rst bead on the g-
clamp.
Take the mobile control unit to work position B.

5) Lift the rim with the tire hooked to it and turn it counterclockwise about 6-8 inches (15-20 cm). The tire will be positioned inclined
across the rim.
6) Move the tool carrier arm to its non-working position. Move it to the inside face of the tire and rehook it in this position.
7) Check to make sure the hook tool is positioned facing the tire bead. If not, press the lever (15, Fig D) and turn it 180°.
8) Move the tool forward until the red reference dot is lined up with the outside edge of the rim and about 2 inches (5 mm) from it
(See Fig. S).
Take the mobile control unit to work position D.
Take the mobile control unit to work position C.

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 rst bead will be mounted on the rim.
Remove the g-clamp.
Take the mobile control unit to work position D.
10) Remove the tool from the tire.
11) Move the tool carrier arm to its non-working position. Move it to the outside face of the tire.
12) Turn the tool 180° with lever (19,Fig. G).
13) Turn the spindle until the valve hole is at the bottom (6 o’clock).
14) Move the ramp (4 Fig. A) under the tire and lower the spindle until the tire is pressed down against the ramp . As the ramp is moved
slightly towards the outside, the tire will open a little and thus create enough space to insert the inner tube.
The valve hole may be asymmetrical to the centre of the rim. In this case position and insert the inner tube as shown in Fig. T.
Insert the valve through the hole and x it with its locking ring.
15) Place the inner tube in the drop center of the rim (to facilitate this, turn the spindle clockwise).
Take the mobile control unit to work position B.

16) Turn the spindle until the valve is at the bottom (6 o’clock).
17) Inate the inner tube a little (until it has no folds) so as not to pinch it while mounting the second bead.
18) Attach an extension to the valve and then remove the locking ring.
The purpose of this operation is to allow the valve to be loose so that it is not ripped out during second bead mounting.
19) Lift the tire again and attach the g-clamp outside the second bead about 8 inches (20 cm) to the right of the valve (See Fig. U).
20) Turn the spindle clockwise until the g-clamp is at 9 o’clock.
21) Move the tool carrier arm (14, Fig. D) to its working position.
22) Bring the tool forward until the red reference dot is lined up with the outside edge of the rim and about 1/4” (5 mm) from it.
23) Turn the spindle a little clockwise until you can insert the bead guide lever into its seating on the hook tool (See Fig. V). This lever
can be supplied on demand.
24) Pull back on this lever which will guide the bead into drop center. Continue to turn the spindle until the tire is completely mounted
on the rim.
25) Remove the g-ramp. Remove the hook tool by turning the spindle counterclockwise and moving it towards the outside.
26) Tip the tool carrier arm to its non-working position.
27) Position the ramp directly under the tire and lower the spindle until the wheel rests on the ramp.
28) When the tire is resting on the ramp, check to make sure the valve is perfectly centered with its hole. If it is not, turn the spindle slightly
to adjust the position. Fix the valve with its locking ring and remove the extension.
29) Close the arms of the spindle completely. Support the tire to prevent it from falling off.
Take the mobile control unit to work position B.
Take the mobile control unit to work position C.

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.

TIRE WITH SPLIT RING
BEAD LOOSENING AND DEMOUNTING
TIRE ASSEMBLY WITH 3-PIECE RINGS
1) Clamp the tire assembly on the spindle as described previously and check to make sure it has been deated.
2) Take the mobile control unit to work position B.
3) Lower the tool carrier arm (14, Fig. D) to its work position until it is locked in position by its hook.
4) Position the bead loosener disk as levelled with the rim (See Fig. W).
5) Turn the spindle and at the same time move the disk forward a bit at a time following the contour of the rim until the rst bead is
completely free (lubricate while doing this).
CAUTION! If the tire has an inner tube, work very carefully and be prepared to stop the disk immediately once the bead has been
loosened so as not to damage the valve and the inner tube.
6) Repeat this procedure but this time bring the disk against the split-ring (See Fig. Z) until the lock ring is freed. Remove this with the
special lever (19, Fig. Z) or with the help of the disk.
7) Remove the split-ring.
8) Move the tool carrier arm (14, Fig. D) back from the edge of the rim. Release the hook and tip the arm to its non-working position.
Move the tool carrier arm to the inside face of the tire.
9) Press lever (15, Fig. D) and turn the tool head 180° which will automatically lock in this position. Lower the arm to its working position.
10) Turn the spindle and at the same time bring the bead loosener disk up against the tire following the contour of the split-ring until the
second bead has been loosened (Lubricate during this process).
Continue to move the disk forward until about half the tire has been demounted from the rim (See Fig. K).
11) Move the tool carrier arm to its non-working position.
12) Move the ramp (4, Fig. A) directly under the tire.
13) Lower the spindle until the tire is resting on the ramp.
