Precautionary Notes

When basic procedures are NOT followed, sharp angled wheel flanges increase
potential damage to tires during mounting. Be sure the mounting head is placed on
the rim with sufficient gap between the bead and bead seat. If the tire is incorrectly
pushed onto the rim by the side of the mounting head, it may become “trapped” and
increases mounting stress to the tire bead.

Insufficient lubrication and failure to place tire into drop center during mounting may

also cause the mount/demount head to fail prematurely.

Bottom Bead Demounting with Tool Head

Position the tire on the rim assembly as shown below. Insert the automatic lever into
the rim / tire assembly.

2.4 Mounting Standard Tire to Rim

Always use this “checklist” as a guide when mounting tires to ensure proper service.

There are four basic steps when mounting a tire to a rim:

 Position the bead on top of the mounting lip of the mount/demount head.

 Position the bead under the demounting lip of the mount/demount head.

 Lock the tire to the rim in the mounting position.

 Slip the bead into the drop center.

These four basic steps to mounting do not necessarily follow the same sequence,
however all four steps need to be performed to mount a tire to a rim.

Connect inflation hose to valve stem.

Pull up on the tire lightly to reduce the gap between upper bead and the rim.

WARNING: Do not stand over tire during inflation.

Step down completely on the air inflation pedal (pedal on the left side of the base) to
release a high-pressure air blast through jets on the clamps to assist in seating the
beads of the tire.

NOTE: To increase the effectiveness of the inflation jets, always

outside. If possible, re-clamp the wheel from the inside
before inflating.

liberally lubricate beads and raise the lower bead while
activating inflation jets.

Step down partially on the pedal to inflate tire and seal beads with inflation hose.
Frequently stop to check bead seating pressure on gauge.

WARNING: Do not exceed tire manufacturer’s maximum pressure

Reinstall valve stem core into the valve stem after beads have been seated, and then
inflate tire to vehicle manufacturer recommended pressure.

If tire is over-inflated, air may be removed from the tire by pressing the brass manual
air release button located below the air pressure gauge.

3. Advanced Procedures

The capabilities of the TCX575 allows the user to utilize numerous advanced
procedures on a variety of rims and tires. For the operator to take advantage of these
features, this section explains in detail what additional steps can be taken.

3.1 Advanced Bead Breaking Procedures

Bead Breaking “AH” Wheels (e.g. BMW M3, M5, Some Porsches, Range
Rover, Lancia, etc.)

“AH” (Asymmetrical Humps), “Bead Locking System” wheels may be identified by
looking on the back of a rim for “AH” in the rim size designation casting
(e.g. 8X17-AH).

“AH” wheels are designed so that the lowest point of the safety hump is located at the
valve stem or 180 degrees out. These two points are where it is easiest to loosen the
bead from the bead seat.

Bead Loosen “AH” Wheels as follows:

Swing the bead breaker arm out and away from the housing.

Position the wheel against the side of the tire changer between the bead breaker arm
and the housing.

Rotate the wheel so that the valve stem is in line with or 180 degrees from the blade.

Swing the bead breaker arm toward the tire and position the blade one to two inches
from the edge of the rim on the sidewall of the tire.

28  3. Advanced Procedures Operation Instructions for TCX575 Tire Changer

Step down on the bead breaker shovel pedal .

The bead breaker arm will be pulled toward the tire changer to loosen the bead.

Release the pedal to disengage the bead breaker arm and then swing the arm to the
open position.

If the bead has not been completely loosened, rotate the wheel 180 degrees and
repeat the bead breaking procedure.

Turn the wheel and loosen the opposite bead using the same procedure.

NOTE: Do not attempt to use the BPS Device for bead breaking. It

is only to be used to loosen beads that have already been
loosened with the side shovel.
