must be checked and adjusted as necessary after intensive
use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Note for adjusting mitre angles > 45°:
Before adjusting the mitre angle, pull the saw table
extension (29) and the adjustable fence (2) all the way out.
Setting Standard Mitre Angles (see figure I1)
