(expand), neutral (stop), and down (retract).
With the clamps in the fully retracted position or clamped against the 
outside of a rim, step down fully on the pedal to expand the wheel clamps 
(clamps move outward). The clamps continue to expand until contacting 
the rim or until fully expanded. 
Internal Clamping: 
Press the pedal all the way down to close the 4 sliding clamps completely. 
Put the wheel on the table top and depress pedal all the way down, (the pedal will move in the 
upper position). The 4 sliding clamps will open and clamp the wheel.
External clamping:
Press the pedal to the middle position to position the 4 sliding clamps so that the reference on 
the table top is more or less in line with the tire diameter stamped on the sliding clamp. 
Place the wheel on the table top and push down on the wheel while depressing the pedal all 
the way to clamp the wheel.
