then readjust.

8.6 Blade Guide Adjustment

The blade is guided by means of pads and bearings.
The guides are adjusted ex works with minimum play.
Make sure to always install 0.9 mm thick blades for which the
blade guide pads and bearings have been adjusted.
For saw blades with a different thickness, the adjustment
should be carried out as follows:
Note:
The position for pad (A, Fig 8-8) and bearings (G) are fixed and
cannot be adjusted.
