7. Operation
Don't use the machine until you have read and understood the entire manual
and the warnings it provides.
The operation of the tire changer is divided into three parts:
1 ). Breaking the bead
2). Demounting the tire
3). Mounting the tire;
Warning: before carrying out any operation, deflate the tire and take off all the
wheel balancing weights.
1). Breaking the bead
Warning: when the bead breaker pedal is operated, anything within the action
range of bead breaker arm can be in the danger of being crushed.
Check that tire is deflated, if not, deflate it.
Close the turntable clamps completely.
Warning: bead breaker with the clamps in the open position can be extremely
dangerous for operator's hands; during the bead breaking operations never
touch the side of the tire.
Position the wheel against the rubber stop on the right side of the tire changer.
Position the bead breaking blade against the tire bead at a distance of about 1
cm from the rim. Pay attention to the blade, which must be correctly onto the
tire not onto the rim.
Press down the pedal (2) to activate the bead breaker and release it when the
blade has reached to the end of its travel or in any case when the bead is
broken.

3). Mounting the Tire
Warning: this checking of tire and rim is of utmost importance to prevent tire
explosion during the inflating operation. Before beginning mounting operation
make sure that:
The tire and the cord fabric are not damaged. If you note the defects, do not
mount the tire.
The rim is without dents and is not warped. Attention with alloy rims, dents
because internal micro-cracks not visible to naked eye. This can compromise
the rim and also be the 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.
When tilting the vertical arm, make sure that nobody stands behind the tire
changer.
When you are working with the rims of the same size, it is not necessary
always to lock and unlock the hex bar. Just tilt and restore the vertical arm
with the horizontal arm and mounting arm locked.
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.
Keep the tire bead pressed down into the wheel rim channel with your hands,
press down on the pedal (1) to rotate the turntable clockwise. Continue until
you have covered the whole circumference to the wheel rim; insert the inner
tube (if there is one).
Repeat the same operations to mount the upper side of the tire.
WARNING: dismounting and mo1,1nting are always done with the clockwise
turntable rotation. Anticlockwise rotation is used only to correct operator's
errors or if the turntable stalls.
