Miter cutting 6-3/4" (171mm) base boards –
This saw can miter cut 6-3/4" (171mm) tall base
boards (Fig. 48) vertically positioned against
the fence (12) at any angle from 47° left to 47°
right miter. All angled cuts must be made with
the base board placed on the left side of the
table (22). For certain cuts, the base board will
have to be flipped upside down or placed with
the face side against the fence. Always use a C-
clamp (Fig. 48) to hold the base board to the
fence before making cuts. Engage the Chop/
Crown Lock. See "Chop/Crown Lock" on page
35.
