10 • 2. Basic Procedures TC3500 Operation Instructions
Remove all weights from the rim to protect the rim and extend life of mount/demount
head (if not done previously).
Identify and recognize special wheel combinations such as Reverse Drop Center,
AH2, and “Run-Flat” Extended Mobility Tires (EMT).
Identify the inner locations on the rim where the rubber pads of the clamping arms
will come in contact in a parallel manner.
Clamping the Wheel from Inside of Rim
If servicing wheels larger than 20 inches in diameter, insert one adaptor, RP6-6494,
into each of the tulip arms.

Verify that removable rubber coated jaws are not installed in clamping arms.
Lift the clamping (left) pedal to retract the clamping device.
NOTE: Periodically clean and degrease the rubber pads to remove
dirt and debris before placing the wheel on the TC3500.
Place the wheel onto the spring-loaded, wheel-centering device.
Push down on the wheel to locate the desired area to which the rubber pads will be
applied. Hold the wheel at this location until properly clamped.
Step down on the clamping pedal until the wheel is completely clamped by the
rubber pads.
Verify that the entire face of the rubber pad contacts the rim. If the rubber pad is
partially pushed against a sharp corner or radius on a rim, the clamping force will
cause uneven pressure and eventually “chunk” the pads.
The amount of pressure being applied by the rubber pads to the rim can be
increased or decreased by depressing or lifting the clamping pedal. Apply only
enough pressure to keep the rim from rotating or coming loose during tire
demounting/mounting. Weak rims (e.g. wire wheels, etc.) can be lightly clamped by
applying minimal pressure.
