Checking and Adjusting the Basic Adjustment
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive

A certain level of experience and appropriate specialty tools
are required for this.
A Bosch after-sales service station will handle this mainte-
nance task quickly and reliably.

must be felt to engage in the detent.
Checking:
The 0° mark of the fine scale 10 must be in alignment with the
0° mark of the scale 9.
Adjusting:
– Remove the insert plate 8.
– Loosen screw 49 with the provided Phillips screwdriver
21 and align the fine scale alongside the 0° marks.
– Retighten the screw again.
Setting the Standard Bevel Angle 0° (Vertical)
