The most convenient locking position on the rim may be selected according to figs E/1 - E/2 - E/3 - E/4 - E/5 and E/6.
Always remember that the safest locking is on the central flange.
N.B. for rims with channel, clamp the wheel so that the channel is near the outside of the rim (fig. E/1).
N.B. for rims exceeding a diameter of 46" and without a flangr with central hole, the wheel can be locked with the 4 extensions 140/90.
The 137/90 clamps - especially designed for operating on light alloy rims without damaging them - is available upon request.
The 137/90 clamps are to be inserted (bayonet-like mounting) into the clamp support of the self-centering chuck (see fig. E/7).
Thanks to a wing screw the clamp can be locked on the support.
Lock the rim as illustrated in fig. E/8. The specially-made 138/90 alloy-rim pliers are also available.
