not to accidentally push the inflating pedal while working.
•When the pedal located on the left side of the machine
body is pushed down to its intermediate position (B),
air is released from the airline gauge.
•When the pedal (C) is pushed down completely, air is
released from the airline gauge with a powerful jet from
the nozzles located on the turntable clamps.
4.5 TURNTABLE LOCKING VALUE ADJUSTING
The tire changer turntable is preset by the manufacturer on a middle range measure from11” to 21”
ext. (considering the rim outer side and) from 13” – 23” int. (if you lock the rim from inner side).
It is however possible to change this dimension range in case of need when working on larger or
small rims; it is enough to change the position of the 4 clamps are shown in the figures below.
The obtainable value starts from a minimum of 10”-20” ext. and 12”-22” int. until a maximum of 12”-
22” ext. and 14”-24” int.
To change the position, proceed as follows:
•Unscrew screw (1) by means of the Allen wrench.
•Remove the locking clamp (2) and the slide piece (3).
•Align the slide hole with one of the guide holes (4) according to the locking dimensions you
want to set. Use the measures below for reference.
It is important to perform the above mentioned operation for all the 4 clamps to
avoid any unbalance in locking phase.

CHAPTER 5 – OPERATION
Do not use the machine until you have read and understood the entire manual
and the warning provided.
Before carrying out any operation, deflate the tire and take off all the wheel
balancing weights.
The operation of the tire changer is divided into three parts:
a) BREAKING THE BEAD b) REMOVING THE TIRE c) MOUNTING THE TIRE
It is advised to equip the tire changer with the pressure regulator.
5.1 BREAKING THE BEAD
Bead breaking must be done with the utmost care and attention. When the bead
breaker pedal is operated the bead breaker arm moves quickly and powerfully.
Anything within its arrange of action can be in danger of being crushed.
•Check that the tire is deflated. If not, deflate it.
•Close the turntable clamps completely.
Bead breaking with the clamps in open position can be extremely dangerous for
operator’s hands.
During bead breaking operations NEVER touch the side of the tire.
•Position the wheel against the rubber stops on the right side of the tire changer (S).
•Position the bead breaker (R) against the tire bead at a distance of about 1 cm from the rim (fig.
8). Pay attention to the blade, which must operate correctly onto the tire and not onto the rim.
•Press down the pedal (U) to activate the bead breaker and release it when the blade has reached
the end of its travel or in any case when the bead is broken.
•Rotate the tire slightly and repeat the operation around the entire circumference if the rim and
from both sides until the bead is completely detached from the rim.

REV. 01 17 / 27
5.2 REMOVING THE TIRE
Before any operation make sure to remove the old wheel balancing weights and
check that the tire is deflated.
During arm tilting make sure that nobody stats behind the tire changer.
•Spread the supplied grease (or grease of a similar type) onto the tire bead.
Failure to use the grease could cause serious damage to the tire bead.
During rim locking MEVER keep your hands under the tire. For a correct
locking operation set the tire exactly in the middle of turntable.
Make sure that the rim is firmly fixed to the clamps.
Never keep your hands onto the wheel: the arm recovery to “working position”
could set the operator at risk of hand crushing between rim and mounting head.
•Lower the mounting bar (M) so that the mounting head (I) rests against the edge of the rim and
lock it using the lever (K). This will lock the arm in both vertical and horizontal direction and
move the mounting head (I) of about 2 mm from the rim.
•With the lever (T) inserted between the bead and the front section of the mounting head (I),
move the tire bead over the mounting head.
•With the lever held in this position, rotate the turntable (Y) in a clockwise direction by pressing
pedal (Z) down until the tire is completely separated from the wheel rim.
In order to avoid damaging the inner tube if there is one, it is advisable to carry
out this operation with the valve about 10 cm right of the mounting head. (Fig.
16)
INNER LOCKING
•Position the clamps (G) so that they are
completely closed.
•Place the tire on the clamps and press the
pedal (V) to open the clamps and thereby
lock the rim.
OUTER LOCKING
•Position the clamps (G) according to the
reference mark on the turntable (Y) by
pressing pedal (V) down to its
intermediate position.
•Place the tire on the clamps and keeping
the rim pressed down, press the pedal (V)
as far as it will go.

REV. 01 18 / 27
•Remove the inner tube if there is one and repeat the operation for the other bead.
5.3 MOUNTING THE TIRE
It is utmost important to check the tire and rim to prevent tire explosion during
the inflating operations. Before beginning mounting operation, make sure that:
The tire and cord fabric are not damaged. If you note defects DO NOT mount
the tire.
The rim is without dents and is not warped. Pay attention to alloy rims, internal
micro-cracks are not visible to naked eye. This can compromise the rim and can
also be a source of danger especially during inflation.
The diameter of the rim and tire are exactly the same. NEVER try to mount a
tire on a rim if you cannot identify the diameter of both.
•Lubricate the tire beads with the special grease in order to avoid damaging them and to
facilitate the mounting operations.
During rim locking MEVER keep your hands under the tire. For a correct
locking operation set the tire exactly in the middle of turntable.
•For 10 to 20 inch wheels lock the rim using the inner part of the clamps.
•For 12 to 22 inch wheels lock the rim using the outer part of the clamps.
When working with rims of the same size it is not necessary always to lock and
unlock the mounting bar; you only need to tilt and return the ram (P) with the
arm and the bar locked in their working positions.
Chains, bracelets, loose clothing or foreign objects in the vicinity of the moving
parts can represent a danger for the operator.

REV. 01 19 / 27
Never keep your hands onto the wheel: the arm recovery to “working position”
could set the operator at risk of hand crushing between rim and mounting head.
•Move the tire so that the bead passes below the front section of the mounting head and is
brought up against the edge of the rear section of the mounting head itself.
•Keeping the tire bead pressed down into the wheel rim channel with your hands, press down on
the pedal (Z) to rotate the turntable clockwise. Continue until you have covered the entire
circumference of the wheel rim (Fig. 12).
To prevent industrial accidents, keep hands and other parts of the body as far as
possible from the tool arm when the table top is turning.
•Insert the inner tube if there is one and repeat the same operations to mount the upper side of
the tire.
Demounting and mounting are always done with the clockwise turntable
rotation. Anticlockwise rotation is used only to correct operator’s errors or if
the turntable stalls.

REV. 01 20 / 27
CHAPTER 6 – INFLATING
The greatest attention is called for when inflating the tires. Keep strictly to the
following instructions since the tire changer is NOT designed and built to
protect (or anyone else in the vicinity of the machine) if the tire bursts
accidentally.
A bust tire can cause serious injury or even death of the operator.
Check carefully that the wheel rim and the tire are of the same size.
Check the state of wear of the tire and that it has no defects before
beginning the inflation.
Inflate the tire with brief jets of air, checking the pressure after every jet.
All our tire changers are automatically limited to a maximum inflating
pressure of 3.5 bar (51 psi). In any case NEVER EXCEEED THE
PRESSURE RECOMMENDED BY THE MANUFACTURER.
Keep your hands and body as far away as possible from the tire.
6.1 INFLATING TIRE USING AIRLINE GAUGE
In the standard version our tire changer are supplied with an airline gauge. To inflate a tire proceed as
follows:
•Connect the airline gauge to the tire valve.
•Make a last check to be certain that tire and rim
diameter correspond.
•Check to be certain that rim and beads are
sufficiently lubricated. If necessary lubricate some
more.
•Seat the beads with short jets of air. Between air
jets, check the air pressure on the inflator gauge.
•Continue to inflate the tire with short jets of air
and constantly checking the pressure between
until the required pressure has been reached.
EXPLOSION HAZARD!
Never exceed 3.5 bar (51 psi) when seating beads or inflating tires.
If a higher inflating pressure is required remove the wheel from turntable
and continue the inflating procedure inside a special protection cage
(commercially available).
Never exceed the max. inflating pressure given by the tire manufacturer.
ALWAYS keep hands and body back from inflating tire.
ONLY special trained personnel are allowed to perform these operations.
Do not allow other persons to operate or to stay near the tire changer.
