6. OPERATION

NOTE：Do not operate the machine before having completing training and qualified for
operating the tire changer. Use appropriate equipment, tools and personal protective
equipment, such as eye-glasses, ear-plugs and working boots, when operating the tire
changer.
Make sure that the power, air sources and the oil level in the oil cup are in accordance with the
requirements.
Principles
• To avoid damage when mounting and demounting tire, especially the alloy ones, use the
specialtire lever.
• For easier demounting and better protection of the tire and rim, lubricate the area between
the rim and tire bead, where the bead breaker shoe goes in, with industrial lubricant or thick
soap solution.
• Pay special attention to rotary direction marked on some flanges or tires.
• Fit the tire on the rim of matched size.
• Check for damages (distortions, surface damages, excessive run out, erosion or overall
wear) before demounting.
• Never ignore the mounting and demounting requirements of the special wheel.
• When inflating the tire, make sure the pressure increases in an even way. Check the rim as
often as possible.
Demounting Tyre
1. Preparing
• Deflate the tire thoroughly.
• Remove all the foreign substance and
weights from the rim (Fig. 13).
Fig.13
2. Demounting
NOTE：Lubricate the bead with a brush with
lubricant before the shoe touches the bead.
• Otherwise the tire bead will be worn (Fig.14)
Place the tire between the bead breaker shoe
and rubber pad and keep the shoe between the
bead and rim, about 1cm to the bead (Fig.15-a).
Depress pedal C (Fig.15-b) to separate the tire
from rim.
