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.
