Preliminary checks
Check that there is a pressure of at least 8 bar on the pressure gauge of the Filter Regulator +
Lubricator unit.
Check that the machine has been adequately connected to the power mains.
Deciding from which side of the wheel the tyre must be demounted
See g. 10.
Find the position of the drop centre A on the wheel rim. Find the largest width B and the smallest width C.
The tyre must be demounted or mounted with the wheel positioned on the turntable with the side
with the smallest width C facing upward.
Special instructions
Some types of wheels on the market require special procedures and precautions which differ from
the standard procedure.
This applies in particular to the following types of wheels:
Alloy rim wheels: some wheels have alloy rims where the drop centre A is very small or non-existent -
g. 10-B. These rims are not approved by the DOT (Department of Transportation) standards - these
initials certify that tyres comply with the safety standards adopted by the United States and Canada
(these wheels cannot be sold in these markets).
DANGER
Take utmost caution when mounting the tyre. The rim and/or the tyre may be damaged
accidentally, with the risk of the tyre exploding during the ination stage.
European style high-performance wheels (asymmetric curvature) - g.10-C: some European
wheels have rims with very pronounced curvature C, except in the area of the valve hole A where the
curvature is less pronounced B. On these wheels the bead must rst be broken in correspondence
with the valve hole, on both the top and bottom sides of the wheel.
Wheels with low pressure indicator system - g.10-D.

USE
BEAD BREAKING
-Fully close the turntable clamps acting on pedal 5 fig. 9.
-Remove the weights from the rim.
-Fully deate the tyre, removing the valve
- Adjust the rim rest depending on wheel diameter
-Place the wheel as shown in g. 11 and take the blade near the bead, keeping the necessary safety
distance between the rim and the bead breaker blade, so that the latter works on the tyre and not
on the rim.
-Press pedal 3 (g 9) to activate the bead breaker and free the bead from the rim.
Release the pedal. Pressing the bead breaker pedal (3 g. 9) the arm moves (4 g.9) and it may be
dangerous (crushing danger); pay the utmost attention during bead breaking.
Repeat this operation on the other side of the wheel.
It may be necessary to break the bead at several points to free it completely.
WHEEL CLAMPING
-Check if there are any weights left on the rim; if so, remove them.
-Thoroughly lubricate the sides of the tyre around the entire circumference of the lower and upper
bead to facilitate the demounting and avoid damaging the beads (g.12).
-Tilt the tower backwards.
-Depending on the diameter of the rim, close the four clamps if the rim is to be clamped from inside
or open them if the rim is to be clamped from outside. Place the wheel on the turntable, push it lightly
down and act on the control pedal to lock the wheel in its proper position (g. 13).
Acting on the turntable pedal (3 g.9) closes the clamps and may be dangerous (danger of hand
crushing). During rim clamping, do not keep the hands under the tyre.

• Tool positioning (g.14 - 15)
- Set the mounting bar in work position and let the
mounting head touch the edge of the rim.
- Adjust the position of the operating arm by
turning the handwheel on the pole unit the tool
has moved 2 to 3 mm away from the edge of the
rim.
- Pull the lever placed on the horizontal arm until
the mounting bar is locked; the mounting head
will automatically move 2/3 mm. away from the
edge of the rim, thus protecting it from damage.
DEMOUNTING
- Position the tyre lever between the mounting
head and the tyre bead and lift the bead above the forward portion of the mounting head itself.
- Make the turntable rotate clockwise by pressing the relevant pedal lightly and repeatedly, then
keep the pedal continuously pressed.
- Rotate the wheel through one turn and at the same time press down with a hand on the side of
the tyre opposite to the mounting head, in order to position the bead in the central groove of the
rim.
- If the wheel has an inner tube, remove it after swinging the horizontal arm + mounting bar in
non-work position.
- Repeat the above described procedures to take out the second bead. Then move the horizontal
arm + mounting bar in non-work position and take the tyre off the rim.

MOUNTING
CAUTION
Always check that the tyre/rim combination is correct in terms of compatibility (tubeless tyre on
tubeless rim; tube type tyre on tube type rim) and geometrical size (keying diameter, cross-section
width, Off-Set and shoulder prole) before mounting.
Also check that rims are not deformed, that their xing holes have not become oval, that they are
not scaled or rusty and that they do not have sharp burrs on the valve holes.
Check that the tyre is in good condition with no signs of damage.
• Tyre preparation (g. 18)
- Grease both the tyre beads.
- Place the tyre on the rim
• Head positioning
- Set the mounting bar in work position

• Lower bead mounting
- Place the bottom bead of the tyre underneath the tool and at the same time apply a little pressure to
the tyre by hand while starting to rotate the wheel (pedal 1) for easier bead insertion.
- Rotate until tyre mounting is complete.
• Upper bead positioning (g. 19)
- Position the upper tyre bead.
Take care that the tyre does not slip underneath the tool.
• Upper bead mounting
- Rotate the wheel using pedal 5 to start mounting the upper bead. Press manually the tyre bead to
keep it inserted in the channel until the bead assembly is successfully completed.
- Return the tool into its rest position.
NOTE: for oversized (more than 19’’) or particularly tough wheels, it is recommended the use of the
pneumatic bead presser. In this case the following procedure must be applied:
• Tyre ination
- For ination, see “INFLATION” section.
• Tilt the tower backwards in non-work position.
• Free the wheel from the clamps and remove it from the tyre changer.
INFLATION
WARNING
Ination is well known to be a dangerous operation. It must be carried out in accordance with
the instructions below. Safety goggles with plain lenses and safety footwear must be worn.
CAUTION
During this operation, noise levels assessed at 85 dB(A) may occur. Operators are advised
to wear hearing protection devices.
DANGER
Although the machine limits the pressure, it does not provide sufcient protection if the tyre
bursts during ination.
Failure to comply with the instructions below will render tyre ination dangerous.
DANGER
NEVER exceed the pressure recommended by the tyre manufacturer. Tyres may burst if they
are inated beyond these limits or their structures may incur serious damage not visible at
the time. KEEP YOUR HANDS AND THE WHOLE BODY WELL AWAY FROM THE TYRE DURING
INFLATION. Make sure you are concentrated during this operation and check tyre pressure
continuously to avoid excess ination. A bursting tyre can cause serious injuries or even death.
- Release the wheel from the sliding clamps on the table top.
- Pull the horizontal arm all away out.
- Lower the vertical bar till it touches the rim.
- Lock the horizontal and vertical arms in the positions described on Fig.2.4.
- Connect the Doyfe ination chuck (32) on the air hose to the valve stem.
- Inate the tyre by using the inaction gun
