# Adjusting the riving knife

The riving knife (4) prevents the saw blade (24) from becoming jammed in the kerf. Otherwise there is a risk of kickback occurring if the saw blade catches in the workpiece.
It is therefore important to ensure that the riving knife is set up correctly:

- The radial clearance between the saw blade and the riving knife must not exceed 3−8 mm (max.).
- The thickness of the riving knife must be smaller than the cutting width and larger than the base blade thickness.
- The riving knife must always be aligned with the saw blade.
- For normal cuts, the riving knife must always be in the highest possible position.

## Adjusting the riving knife height (see figure F)

The height of the riving knife must be adjusted in order to saw grooves.

- Only use the power tool for grooving or routing if a suitable protective guard (e.g. tunnel blade guard, featherboard) is in place.

- Open the clamping lever (37) and pull the protective cover (3) out of the groove on the riving knife (4).
  To prevent damage to the protective guard, store it in the bracket (11) provided on the housing (see figure ).
- Turn the crank (15) clockwise as far as possible so that the saw blade (24) is in the highest possible position above the saw table.
- Release the clamping lever (34) clockwise until it points upwards.
- Pull the riving knife off the pins (35) (pull the clamping lever (34) outwards slightly) and push the riving knife (4) down as far as possible.
- Allow both pins (35) to engage in the upper bore holes in the riving knife and then retighten the clamping lever (34).
  The markings (33) on the clamp and clamping lever (34) must be aligned as shown.
