The couplings are designed to acommodate a certain style of quick-release lever.

If you use an incompatible quick-release lever, it may not be properly supported be the

coupling --- so you must change your quick-release to the correct style in order to

prevent accidents.

If the rollers are rubbing against or touching

the tire, it may cause the tire to burst.

Roller-to-rim contact ONLY! (see Fig. I)

Be careful not to pinch fingers in springs while adjusting.

The Left-side coupling has a cut-away section to accomodate the shaft of the quick-

release lever. You must align this coupling with the shaft of the QR. Failure to do

so may cause the coupling to improperly support the bicycle.

Once you have set the correct position of the rim for your bicycle, you can install or

remove your bicycle by rotating only one hub-clamp handle. This feature saves

time.

The yellow levers control the release and placement of the rollers to the rim. By adjusting

these levers, you will see that the two rollers contact the rim sidewall with equal tension.

If they are not resting on the rim properly, but on the tire, then you must re-adjust the height of

the drive pulleys so that the roller contact is solely with the rim. (see Fig. H)
