9.4.3Extension plate

The extension plate (D, Figure 17) can be adjusted by sliding to the right or left or removed entirely.

To adjust, loosen two lock handles (E), slide the extension plate and retighten lock handles. Make sure end of extension plate is not in blade path.

NOTE: The lock handles (E) are adjustable. Pull out on handle, rotate it to different position, then release, making sure it seats itself upon the pin.

To remove extension plate, slide it completely off and remove lock handles (E) and mounting hardware.

9.4.4Calibration

1.Place miter gauge into one of the slots on the table.

2.Set miter gauge at 90º to blade (0º setting on the scale) by loosening lock handle (A), then pulling out spring-loaded knob (C) and turning body (B) until 0º is indicated on scale.

3.Measure accuracy of miter gauge against slot with a combination square.

If adjustment is needed:

4.Adjust body (B) until it is square (90º) to miter slot.

5.Tighten lock handle (A).

6.Verify that scale indicator (G) reads 0º. If further adjustment is needed:

7.Loosen screw (F) and adjust indicator (G) until it reads 0º.

8.Tighten screw (F).

9.If the above procedure does not satisfactorily align the miter gauge, loosen two screws (J, Figure 18) beneath mounting block and shift block as needed. Retighten screws when finished.

Figure 18

NOTE: The bar of the miter gauge has two slots with set screws (H, Figure 17). Adjust these set

screws (4mm hex key) to eliminate any play between bar and miter slot.

9.5Blade tilt stop adjustment

The stops for 90°, 45° blade tilt, and elevation settings have all been factory set, and should require no immediate adjustment. The settings should be confirmed by the operator, however, and especially if cuts become inaccurate. Both tilt stops are located inside cabinet in front of the motor.

9.5.1Tilt stop 90°

1.Disconnect machine from power source.

2.Make sure table insert has been leveled with table surface. See section 7.11.

3.Raise blade all the way, and place a 90° square on the table and against blade (Figure 19). Make sure that a blade tooth does not obstruct the actual reading.

Figure 19

4.Tilt blade with handwheel until square and blade are flush.

5.If adjustment is required, loosen nut (A1, Figure 20) on 90° stop screw (A2) with a 12mm wrench, and turn screw to proper height. Verify setting and retighten nut.

6.Check pointer position (Figure 21). If needed, loosen screw and adjust pointer to zero. Retighten screw.
