Cutting Base Molding

ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANY CUTS.
Straight 90˚ cuts –Position the wood against the fence and clamp it in place as shown in Figure 19.
Turn on the saw, allow the blade to reach full speed and lower the arm smoothly through the cut.
Cutting base molding up to 3-7/8" high vertically against the fence
Position molding as shown in Figure 20. All cuts made with the back of the molding against the fence
and bottom of the molding against the table.

Material up to 3.9" (3-7/8)" can be cut as described above. For wider boards [up to 5.5" (5-1/2")] sev-
eral minor concessions must be made.
When cutting a board between 3.9" (3-7/8") and 5.5" (5-1/2") in width the guard will hang up on the
work piece. If this occurs, simply place your right thumb on the upper side of the guard and roll the
guard up just enough to clear the work piece, as shown in Figure 23. Once you have cleared the work
piece, you can release the guard and it will continue to open as the cut progresses.
When mitering to the right side of a base molding wider than 3.9" (3-7/8") standing vertically against
the fence as in Figure 20, the saw can only cut through the board up to 1 inch from the end of the
board. Trying to cut more than an inch will cause the saw's gear case to interfere with the work piece.
If you want to cut base molding between 3-7/8" and 5-1/2" wide vertically see the following the direc-
tions.

N N O O T T E E : : If the cut must be made somewhere other than 1" from the
