Miter Detent System – Adjustment procedure
Calibrating Miter Detent System
1. Engage the miter detent at the 0° position. Loosen
the miter lock knob 1/2 turn.
2. Look for four round holes in the miter scale plate.
In each hole is a screw. Use the small end of the
6/4mm hex key or a 4mm hex key to loosen all
four screws 1 to 2 turns. This will loosen the miter
detent plate (see Figure 18).
3. Lock saw down using the head assembly lock pin
(item 43 – page 9).
4. Hold one side of a 90° combination square against
the fence and rotate the table (and detent plate)
until the side of the saw blade is in full contact with
the other side of the square.

Kerf Insert Adjustment
The kerf inserts should be adjusted close to the
blade, but without touching the blade, to avoid tear-
out on the bottom of the workpiece.
1. Hold the saw head assembly down and push in
the head assembly lock pin (item 43 – page 9) to
keep the saw in the DOWN position.
2. Loosen the six kerf screws using a #2 Phillips
screwdriver.
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.
