over the support of the mount/demount tool. Lift
the bead onto the mounting finger. To facilitate
this operation, press with left hand on the bead in
position diametrically opposite to that of the tool. If

Tool Head Angular adjustment

(Fig. 5.1-8)
The tool is adjusted at the factory with an optimal angle
for most wheels used today. However, the angle can
be optimised for wheels with a diameter that differs
considerably from the standard.
To adjust the tool angle, proceed as follows:
1 Mount the rim for which the adjustment is required.
2 Loosen the lower screw (1).
3 Adjust the tool with the screws shown (2a and
2b). Unscrew the screw 2a or 2b to rotate the tool,
respectively clockwise or counterclockwise.
4 Screw in the opposite screw to block the tool in the
desired angular position.
5 Tighten the lower screw (1) with a torque of 35 Nm.
