Operation

Attention:
The use of this machine is reserved to specially
trained and authorized personnel. Use appropriate
equipment, tools and personal protective equipment,
such as eye-glasses, ear-plugs and working boots,
when operating the tyre changer. Make sure that the
power, air sources and the oil level in the oil cup are
in accordance with the requirements.

Principles

l To avoid damage when mounting and demounting
tyre, especially the alloy ones, use the tyre lever
offered by manufacturer.
For easier demounting and better protection of the
l
tyre and rim, lubricate the area between the rim and
tyre bead, where the bead breaker shoe goes in,
with industrial lubricant or thick soap solution.
l Check for damages (distortions, surface damages,
excessive runout, erosion or overall wear) before
demounting.
Pay special attention to rotary direction marked on
l
some flanges or tyres.
l Fit the tyre on the rim of matched size.
Never ignore the mounting and demounting
l
requirements of the special wheel.
When inflating the tyre, make sure the pressure
l
increases in an even way. Pay attention to status of
the tyre bead.

Demounting
Attention:
Lubricate the bead with a brush dipped in soap
solution before the shoe touches the bead.

bead and rim, about 1cm to the bead (Fig. 05).
Depress pedal (I)(Fig. 06) to separate the tyre from

l Repeat the above steps on other part of the tyre to
get the tyre separated thoroughly from the rim.
