2. Raise the cutting head to the upright position.
3. Raise the lower blade guard (1) to the uppermost
position (Fig. 44).
4. Loosen the cover plate screw (2) with a screwdriver.
5. Rotate the cover plate (3) backward to expose the arbor

contact with the base or the miter table by spinning
the blade manually.
