Secure the Wheel on the Turntable
Before you can demount a Tire, you must secure the Wheel on the Turntable.
The Tire Changer supports two ways of securing the Wheel to the Turntable:
•
External clamping. The Clamps are on the outside, pressing inwards.
•
Internal clamping. The Clamps are on the inside, pressing outwards.
As a general rule, steel Wheels clamp internally (Clamps push out against Wheel) and custom and mag
Wheels clamp externally (Clamps push in against outside Rim edge). Check with your supervisor if you
are unclear about which method to use.
To secure a Wheel on the Turntable:
1. Make sure you are wearing OSHA-approved (publication 3151) personal protective equipment:
leather gloves, steel-toed work boots, back belts, hearing protection, and ANSI-approved eye
protection (safety glasses, face shield, or goggles).
2. Identify the Narrow side of the Tire; this side goes up.
3. Determine which clamping method you are going to use.

–
If you are clamping internally, press

4. Put the Wheel onto the Turntable, either between the Clamps that are all the way out for external
clamping or over the Clamps that are all the way in for internal clamping.
5. Secure the Wheel:
–
If you are clamping externally, press down on the Clamps Foot Pedal to move the Clamps in
until the Wheel is being firmly held in place.
–
If you are clamping internally. press up on the Clamps Foot Pedal to move the Clamps out
until the Wheel is being firmly held in place.

Clamping externally can be difficult on some Tires. If you are having problems getting the
Clamps to clamp externally, either press down on the Wheel from above or, if you are
using the R980AT, use the Restraint Cone to push the Wheel down from above. Pushing
down from above moves the Rim away from the Tire, making it easier for the Clamps to
grab the Rim.
