Kerf Insert; Depth Adjustment - Bosch 4412 Operating/Safety Instructions Manual

The kerf insert should be adjusted close to the blade,
but without touching the blade, to avoid tear-out on
the bottom of the workpiece.
1. Lower the head assembly and lock into position.
2. Loosen the six (6) kerf screws using the multi pur-
pose tool (Figure 12).
3. Adjust the kerf inserts as close to the blade (teeth)
as possible without touching the blade.
4. Tighten the kerf screws.
NOTE: At extreme bevel angles the saw blade may
slightly cut into kerf insert.
— When the diameter of the blade has been reduced
due to sharpening, it may be necessary to adjust
the depth stop. When a new blade is installed, it
is necessary to check the clearance of the blade
to the turn table structure.
Setting Blade Depth for
Normal Full Cuts
— The depth stop adjustment is a feature used when
cutting grooves in the workpiece. (See page 27 for
cutting grooves.)
1. Loosen and turn both Jam Nuts to just above the
threaded end of the Depth Stop Bolt (Figure 13).

Stop Bolt to set the blade depth to about 1/4 inch
below the table's surface.
5. Release the saw head to the up position.
6. Turn both Jam Nuts to be tight against the bottom
of the support frame. Tighten nuts against each
other.
7. Practice slide cutting (with tool unplugged) to veri-
fy that the blade does not touch table. If it clears
the table, make a practice cut (with tool plugged)
on scrap wood to verify that the cut goes com-

could be ruined if it cuts into the table structure.
