2.2 Sharpening the blade:

Important:
Before sharpening, the machine must under all circumstances guided out of the fabric. Pressure foot
should lie on base plate, i. e. it should be brought to the lowest position. Automatic sharpening unit is
started by a short depression of lever. It runs along the total blade length and switches itself off - after
the sharpening process - at the top dead centre.
Caution:
Operate the automatic sharpening unit only with the grinding wheels in position.
If the lever (16) becomes blocked, the pawl (17) must be lifted.
The release lever (16) for the automatic sharpening unit can be actuated a second time as the blade
moves upward for the additionally sharpening the tip of the blade. In this way, the automatic sharpening
unit reverses, and intensively grinds the tip of the blade.

optimum resharpening of the blade be ensured.

unusual characteristics. For particularly soft material, we recommend fine-grain grinding wheels.
