Operation Instructions for TCX575 Tire Changer  2. Basic Procedures  13 
2.2 Placing Wheel on Tire Changer 
Identify and recognize special wheel combinations such as Reverse Drop Center 
(needs inverted on changer), AH, “Run-Flat” Extended Mobility Tires, and standard 
tires with pressure sensors.  
Clamping the Wheel from Inside of Rim - Steel Rims 
Identify the inner locations on the rim where the clamps will come in contact. 
Position the clamps in the fully retracted position (clamps completely in).  
Place the wheel centered onto the turntable. 
Step down on the clamping pedal   to expand the clamps to the rim. 
NOTE:  Avoid clamping inside
 rim of alloy wheels.  Steel jaws 
may damage the finish of inside rim surface during use. 
Verify that the wheel has been properly clamped and centered. 
Clamping the Wheel from Outside of Rim - Alloy Rims 
Place the clamping pedal   in the stopped position by partially stepping down 
on the pedal with the clamps expanding or in the fully expanded position. 
From this stopped position, use additional partial steps on the clamping pedal to 
incrementally retract the clamps. Set the clamps to the mark on the turntable that 
corresponds to the size of rim to be clamped (12”- 14” - 16”). 
Place the wheel onto the turntable. 
Continue to incrementally retract the clamps until all four clamps contact the rim. 
Step down once only on the clamping pedal   to fully retract the clamps to the 
rim. 
NOTE:    Always verify that all four clamps are on the rim before 
applying pressure to prevent possible failure. 
Plastic jaw covers may be used to help maintain rim protection when clamping 
externally. Plastic jaw covers may be replaced periodically when worn by ordering  
kit RP11-8-11400085 which contains 2 sets of plastic covers. 
2.3 Demounting Standard Tire from Rim  
Top Bead Demounting 
Position the mount/demount head against the outer edge of the upper rim lip. The 
plastic surfaces should contact the rim lip. 
Slide the mount/demount head in or out along the upper rail and lower the head into 
position. Push the button on handle to lock head into position. The mount / demount 
head will automatically build in the proper spacing.
