Setting options for the clamping
bracket
The closing width of the clamping bracket may
need adjusting later if e.g. the clamp lever
cannot be closed or the clamping bracket does
not surround the tube firmly. The width of the
clamping bracket can be adjusted for tube
thicknesses of 24-26 mm.

The M5 protection screw (Metric size 2.5 mm)
and the M4 clamp screw (Metric size 2 mm)
must be released for adjustment. This enables
the width of the clamping bracket to be ad-
justed (clockwise for a smaller diameter/anti-
clockwise for a larger diameter) by turning the
eccentric shaft.

force for opening and closing the clamping bracket
Attention must be paid here to ensure that the
slit on the back of the eccentric shaft points
precisely to one of the marking points attached
to the clamp by turning the eccentric shaft (Fig.
40). This ensures that the securing screw
points precisely to one of the areas attached to
the eccentric shaft for this purpose during
tightening. Only then is independent turning of
the eccentric shaft excluded.
