and raise it until the rim flange touches the bead
breaking tool. Using the control and selector
deflate the tyre and begin the bead breaking
operation ( Fig. 19 or Fig. 16 ). Use the pedal
and selector to graudally advance the bead
breaking roller turning the spindle continuously.
- Lubricate the bead and the rim flange with the
special lubricant keeping the wheel in movement.
When the operation is finished rotate the tool by
180º, removing the pin. Repeat the bead
breaking on the other side of the tyre in the same
way.
- Tilt the toll arm and move it back of the tyre
pressing the pedal. Using the lever swing the tool
into position 2 then re-attach the tool arm to the
trolley. Use the control to move the tool againts
the tyre with the control until the bead is hooked
on Fig. 20. Put the tyre into tension moving the
rim away from the tool so that the bead enters
the channel.
- Insert the special lever ( Fig.21/Fig. 8 ) between
the rim and bead to the right of the tool to ensure
that the bead remains on the tool. Move the rim
towards the tool again ( Fig. 21 ) until the front
bead has completely come out. Rest the wheel
on the trolley platform to obtain working space for
the easy removal of the inner tube.
