The most convenient clamping 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 clamping is on the central flange.
For rims with a drop center clamping, clamp the wheel so that the drop center is near the outside of the rim (fig. E/1).
For rims exceeding a diameter of 46" and without a flange with center hole, the rim can be clamped with the 4 clamping extensions
provided on demand (# 9299270)
(# 9299272) LIGHT-ALLOY RIM CLAMPING
A set of specialclamps - especially designed for operating on light alloy rims without damaging them - is available upon request.
These clamps are to be inserted (bayonet-like mounting) into the jaw support of the self-centering chuck (see fig. E/7).
Thanks to a wing screw the clamp can be locked on the support.
Clamp the rim as illustrated in fig. E/8. The specially-made alloy-rim pliers are also available (#9299272).
DANGER!
Do not walk across the work area with a wheel clamped on the tire changer and lifted up from the
floor.
