Operation Instructions for TCX50H Tire Charger
46
Demounting the Inner Bead
1. If the wheel has a sensor, rotate the table top until it lines up with the toolhead.
2. Position the tire lifting disc under the inner bead, then, using the BPS control lever, lift the
bead until it is in the middle of the drop center. Take care not to damage the sensor when
doing this.
3. Insert the bead lifting lever on the toolhead until it has picked up the inner bead. Raise the
bead lifting lever until the inner bead rises on to the toolhead.
4. Turn the table top clockwise until the tire has been completely removed.
Operations and Inspections Prior to Mounting
1. Check the tire and rim for any defects.
2. If the wheel has an internal sensor, make sure that it is not defective and/or damaged. If
damage is discovered, replace the sensor (refer to vehicle’s maintenance manual).
Mounting the Inner Bead
1. Clamp the rim on to the table top from the outside only.
2. Move the tool arm to the work position and clamp the toolhead on to the rim.
3. Thoroughly lubricate the rim and tire beads.
4. If the wheel has an internal sensor, position it on the right hand side of the toolhead.
5. Position the tire so that the inner bead (lower one) is under the toolhead.
6. Turn the table top clockwise. Keep the tire pressed against the rim so that the inner bead
“slips” into the drop center.
Mounting
Follow these steps:
1. Clamp the rim on the tabletop and mount the outer bead as described in Chapter 2, Basic
Procedures, page 22.
2. Position the roller near the mount/demount head. Lower it until the inner bead is level with
the center well. If the tire bead fails to “rise” on the mount/demount head, using the bead
lever can facilitate the operation.
3. As the turntable turns the roller will revolve with the tire and keep the bead in the well. The
second bead will thus be mounted on the rim without any effort or danger to the operator
and without damaging the tire.
