Set the lateral guide bearings so that they contact the
sawblade lightly.
The sawblade may not be pushed out of place.
Loosen the lock knobs (G).
Adjust the lateral guide bearings by rotating the knurled
knobs (H).
Note:
Set the lateral guide bearings so that they contact the

A quick way to achieve the spacing needed (~0.1mm) is
placing a paper note between blade and guide bearing (Fig
47).
