5.3 Operation
The Bead Press System has been designed to facilitate the operations of wheel locking and
mounting/demounting the tire on or from the rim. These operations, especially with low-prole,
very wide tires, or very hard beads can be very difcult.
Clamping the Wheel
Break the beads of the tire following the instructions in Section 2.1, Bead Breaking, page
22.
If you plan to clamp the wheel from the inside, follow the instructions in Section 2.2, Clamping
the Wheel from Inside of Rim - Steel Rims, page 23.
If you plan to clamp the wheel from the outside, the Bead Press System can help with this
operation. Follow these steps:
1. Release the turntable, bringing the tire changer operating arm and the Bead Press System
to a non-working position.
2. Select the turntable opening so that the jaws touch the tire near the rim, when putting the
wheel on the turntable.
3. Insert the rim pressure cone on the arm and push it upwards making sure the bayonet lock
slips into place.
4. Set the arm in work position, it will automatically lock in line with the turntable.
5. Lower lever until the cone, as it presses against the wheel, forces it down a couple of
centimeters. (The bead presser must be positioned so as not to touch the tire).
6. Close the clamps on the wheel. Raise the lever until the cone is above the wheel far
enough to be removed. Remove the bead pressing cone and bring the arm back to its
non-working position.
Lubrication of Outer Bead
If the outer bead of the tire has “re-seated”, the bead loosening procedure can be repeated
with the Bead Press System rather than the side shovel. Follow these steps:
1. Pull the roller locking knob towards the outside so that the roller is free to turn on its axis.
(For all other operations done with the Bead Press System, this knob must be inserted to
prevent the roller from turning).
2. Bring the arm to its work position. Press the lever so that the roller can slide on the arm
and position near the edge of the rim. Release the lever.
